  • the term “manual cleaning device” is used to refer to a completed item of manufacture, comprising the combination of a hand-covering article (e.g., a mitt or a glove or a variation thereof) and a cleaning implement, preferably in the form of a pad.
  • the cleaning element could comprise, for example, a pad of sponge material, a scouring pad, or a pad carrying abrasive or brush bristles.
  • the pad applied has a thickness many times that of the thickness of the latex rubber skin.
  • the hand-covering article is preferably formed by dipping a former into a vat of suitable elastomeric material, such as natural latex rubber or a synthetic eguivalent thereof as well as related materials such as vinyl, liquid silicone, NITRILE and PVC (polyvinyl chloride) .
  • suitable elastomeric material such as natural latex rubber or a synthetic eguivalent thereof as well as related materials such as vinyl, liquid silicone, NITRILE and PVC (polyvinyl chloride) .
  • suitable elastomeric material such as natural latex rubber or a synthetic eguivalent thereof as well as related materials such as vinyl, liquid silicone, NITRILE and PVC (polyvinyl chloride) .
  • Such processes include, for example, manipulating the former so as to distribute the latex material in a desired manner over the former (e.g., turning the former to prevent unwanted drips) and subsequently curing the latex rubber skin so that it takes on a commercially useful toughness.
  • manipulating the former so as to distribute the latex material in a desired manner over the former (e.g., turning the former to prevent unwanted drips) and subsequently curing the latex rubber skin so that it takes on a commercially useful toughness.
  • a number of significant manufacturing steps are performed before curing of the latex rubber skin.
  • a former 10 is carried on a conveyor 12 in a continuous in-line process, so as to be positioned over a vat 14 filled with a conventional latex rubber composition 16.
  • former 10 includes a raised border 18, preferably in the form of a closed loop encircling the part of the mitt corresponding to the palm of a user's hand.
  • Border 18 surrounds a bordered area 20.
  • the border 18 need not be continuous and need not be of the size and shape shown in FIG. 1. In the illustrated embodiment, the bordered area is not recessed in the sense that it has been depressed compared to similar mitts lacking the border feature.
  • the latex rubber article which is constructed using such a former, has a full thickness to comfortably receive a user's hand, and the border 18 is raised with respect to the remainder of the mitt.
  • the border is raised by an amount d ranging between .5 mm to 5 mm and most preferably between 2 mm and 3 mm (see FIG. 7) .
  • the former 10 is dipped into the latex rubber composition 16 with a coating or "skin" of latex rubber adhering to the outer surface of the former, so as to cling to the former upon its removal from vat 14, as illustrated in FIG. 3.
  • the covering eventually becomes a latex hand-covering article 28 (i.e., either a glove or a mitt or a variation thereof) .
  • the latex hand- covering article to be formed takes the shape of a mitt, and the bordered portion 20 extends over the palm of the hand.
  • the latex rubber composition 16 is of a conven ⁇ tional type, and may be substituted by other liquid compositions suitable for forming a pliable handwear article.
  • the resulting latex rubber skin closely conforms to the surface features of former 10, and accordingly, a bordered portion 28 is formed in the latex skin, and is surrounded by a raised border 24, which conforms to the raised border 18 of former 10.
  • the latex skin recovered from vat 14 initially has a slippery outer surface, which remains so until the skin is cured and dried to form a useable latex rubber article.
  • the pad of cleaning media is joined without adhesive to the hand-covering article (i.e., either mitt or glove or a combination thereof) , by using the latex material itself to bond the pad to the hand covering article with sufficient strength that the cleaning device may be used repeatedly for vigorous scrubbing and cleaning operation without separation of the pad from the article.
  • a cleaning media 34 preferably in the form of a pad, is partly dipped in a vat 36 of latex rubber composition 16.
  • only one major face of the cleaning device 34 is coated with the latex rubber composition. As will be seen, this is an optional step which can be omitted in some instances. As can be seen in FIG.
  • the cleaning pad 34 is applied to the bordered portion 28 of the latex rubber skin.
  • the former undergoes a series of turns or undulations before assuming a horizontal position.
  • the fabrication step may be carried out as illustrated in FIG. 6, but is preferably carried out with the former assuming a horizontal position.
  • the former 10 may be manually positioned, but is preferably automatically positioned under control of a scanner or sensor 35 so as to locate the latex rubber skin at a known position with respect to an automated placement arm 37 which automatically places the pad 34 in a desired position, as illustrated in FIG. 6, using a mechanized arrangement (not shown in the drawings) . It is contemplated that the pad 34 be obtained from a staging point where a plurality of pads are stacked together, ready for manual or automatic assembly with a succession of latex rubber skins carried by formers 10 along the conveyor line 12.
  • the coated pad 34 can be exposed to a radiant heater, a stream of hot air provided by manifold 33, or other heat source to induce tackiness to the latex coating on the pad.
  • the latex rubber skin carried on former 10 may also be exposed to a hot air stream, if desired, preparatory to mating with the pad 34.
  • cleaning device 34 is surrounded by the raised border 24, which provides a number of advantages, including helping to maintain cleaning media 34 in its desired position on the latex rubber skin, resisting the tendency of the cleaning media to slide off of the skin, due to gravitational or vibrational forces, for example.
  • the latex rubber article has a thickness generally comparable to that of commercially available rubber gloves, with the border 24 being raised by an amount d on the order of a few millimeters.
  • the thickness of pad 34 is typically many times greater, having a thickness ranging between 1/16 inch and 1/2 inch.
  • the former is made to undergo a series of turns after dipping, in order to control formation of a latex rubber skin, so as to ensure, for example, a uniformity of thickness in the latex rubber skin, as well as avoiding drips and other blemishes encountered in this type of dipping operation.
  • the raised border is seen to provide significant advantages, whether the latex rubber skin carried on former 10 is wet and slippery, or alternatively is tacky. In either event, the raised border enhances the placement, whether a manual placement or an automated placement of pad and latex rubber skin.
  • the raised border mentioned above be omitted.
  • more costly automated equipment may be available to a manufacturer, which can reliably place pads on a latex rubber article, with a high degree of dimensional accuracy.
  • skilled workers may be able to accurately position pads on a latex rubber article with a high degree of precision, in conjunction with manufacturing processes which reduce the probability of a pad, once placed, from becoming misaligned with the latex rubber article.
  • a raised border can provide other significant advantages.
  • a raised border can be relied upon to present a visual target to either human operators or robotic placement and the like automated machinery which employ visual orientation techniques for alignment of the equipment with respect to a latex rubber article.
  • a raised border can also be employed to provide additional bonding area to a pad (i.e., to the side edges of the pad) and to support the pad in use.
  • a user's rubbing motions will impart a shear stress to the bond between the pad and latex rubber article.
  • a raised border abutting the side edges of the pad will support the pad against such stresses. See, for example, FIGS. 22-25 which show pads which are more susceptible to dislodging under the effect of shear stresses particularly when the pads present a relatively high coefficient of friction to a surface being worked (for example, a sanding operation performed on a porous wood substrate) .
  • the latex-to- latex fusing is accomplished by using identical latex compositions to coat both the pad and the former. Upon mechanically joining or pressing the two together, the latex coating from one component contacts the latex coating of the other component so as to form a bond which is strengthened when the latex materials on the components are subsequently cured.
  • latex material on the former is understood to intermingle with latex material carried on the pad, with the latex coating of one intimately and homo ⁇ geneously mixing with the latex rubber coating of the other, coming together to form a single homogeneous mass.
  • the two coatings are capable of fusing together and interblending with one another so that one uniformly disperses into the other.
  • the fusing may rely upon a fluid or a semifluid nature of the coatings on the pad and the former so as to allow a flowing together to form an indivisible blending of the two coatings.
  • the latex coating on the cleaning pad 34 and latex rubber skin on former 10 are allowed to cure, thus effectively bonding the cleaning device to the latex rubber skin. Curing may be facilitated and/or accel ⁇ erated using known techniques, such as drying, heating or contacting the latex rubber with a known solution which treats the surface for toughening, for example.
  • the former illustrated in FIG. 6 is preferably soaked in a vat containing a treating solution..
  • the item carried on former 10 is then regarded as a completely formed manual cleaning device 30, referred to herein as a hand- covering article (such as a mitt or glove, for example) of latex rubber which is then presented to a final work station for removal from the former 10.
  • a hand- covering article such as a mitt or glove, for example
  • the hand- covering article may alone comprise a commercially viable product by itself.
  • prior art removal techniques involved everting the latex rubber article 50, i.e., turning it inside-out.
  • a cleaning pad such as the cleaning media 34
  • the cleaning media would be applied to the exposed outer surface 52 of the everted handwear article, i.e., the surface originally in contact with the former 10.
  • Any flocking or other lining would typically be applied to the surface 54 facing away from the former prior to removal of the article from the former. Internal stress and strain resulting from turning the article inside-out could be present in the article throughout its life.
  • the latex rubber skin on the former may be allowed to penetrate the surface portion of the pad directly so as to provide the basis for a secure mechanical bond when the latex rubber material is allowed to cure or harden.
  • the former having a raised border, described above.
  • the for er may be dipped in a latex rubber or other suitable solution so as to form a puddle or pool of solution in the area surrounded by the raised border.
  • the area thus surrounded will have an increased thickness or depth of solution which can penetrate into a pad applied to the bordered area.
  • the manufacturing process of forming the latex rubber article involves dipping a former into a vat of latex rubber or other suitable solution.
  • the present invention also contemplates pouring or spraying solution onto a former so as to supplement, or even replace, the aforedescribed dipping operation.
  • the production of manual cleaning devices and latex rubber articles incorporated therein are preferably formed in a continuous operation, with a series of formers carried on a suitable conveyor.
  • the present invention also applies to the production of latex rubber articles and manual cleaning devices incorporating those articles formed in a batch process. For example, a single former can be dipped, poured upon or sprayed to produce a latex rubber article.
  • a plurality of such formers can be carried on a common backing support for simultaneous dipping in a vat of latex rubber solution.
  • simultaneous manipulation of multiple formers would also be useful for a simultaneous spraying or pouring operation performed in addition to or in place of a dipping operation.
  • the cleaning device Referring now to FIG. 8, according to one aspect of the preferred embodiment, the cleaning device
  • any flocking or lining to be formed on the inside surface of the latex rubber article during its manufacture may be applied to the outer surface of former 10, preparatory to dipping in the composition 16.
  • a cotton or jersey glove or mitt or a nylon liner or a mitt may be slipped onto the former prior to dipping to facilitate donning and to add a desired body to the manual cleaning device.
  • an oscillatory or jiggling motion can be applied to the pad in the method step indicated in FIG. 6 to further seat the pad against the latex rubber skin, enhancing the void reduction, and encouraging mixing of the latex material carried on the pad with that carried on the former.
  • Such additional steps may offer advantages in extending the "hold" time for the latex rubber skin before the pad is applied, since movement of a pad contacting the latex rubber skin may break through any surface effects formed on the latex rubber skin.
  • the raised border 24 in the latex rubber skin allows the former to undergo a range of motion even when the surface of the latex rubber is in a fluid or slippery state without separation of the pad from the skin. As can be seen in FIG.
  • the media 34 is cradled in a recess formed by the raised border 24, and accordingly, the former can be twisted and moved in various directions to reduce drip formation and other imperfections. As mentioned above, it may be desirable in some instances to rotate and move the former 10 in extreme (even inverted) positions to reduce drip formation and to distribute the latex rubber material in a uniform fashion about former 10.
  • a former 70 having a raised border 72 is prepared for a dipping in the vat 14, as illustrated in FIG. 11, so as to form a latex rubber skin when the former is removed, as illustrated in FIG. 12.
  • a pad 76 has a major face thereof dipped in a vat 36 of latex rubber solution 16, as indicated in
  • the pad 76 is then applied to the latex rubber skin, while the skin is still "wet", that is, uncured.
  • the skin at this point may or may not be tacky.
  • the latex rubber skin has a raised border 80 which conforms to the raised border 72 of the former.
  • the pad 76 is placed within raised border 80, as illustrated in FIG. 15.
  • the latex rubber is then cured in a conven ⁇ tional fashion to produce a latex rubber article of usable toughness.
  • the pad 76 is integrally fused to the latex rubber article, with the combination comprising a completed cleaning device 84. As indicated by the arrow in FIG. 15, the cleaning device 84 is removed or stripped from former 70 without turning the latex rubber article inside-out.
  • cleaning pads may be affixed to the opposed surfaces of a latex rubber article, with raised borders on both sides providing sufficient retention of both pads, an important feature since the former cannot be adjusted to a position where dislodging gravitational forces, acting in shear on the applied pads, can otherwise be simultaneously eliminated for both sides of the latex article.
  • halogenation of the mitt may result in deterioration of the sponge pad, particularly in the case of synthetic sponge pads. It has been found that halogenation, i.e., dipping of the mitt in a halogen solution, such as a chlorine or bromine solution, improves certain surface characteristics of the finished mitt. In particular, halogenation of the finished mitts aids in preventing the opposite surfaces of the mitt from adhering to each other, and reduces the difficulty encountered by a user when inserting or removing one's hand.
  • a halogen solution such as a chlorine or bromine solution
  • the absence of halogenation generally is not problematic with respect to the interior surfaces of the mitt.
  • the exterior surface of the mitt may still have undesirable qualities such as, e.g., the surface may be somewhat sticky, or tacky, or have a high coefficient of friction when in contact with certain materials.
  • the quality of the exterior surface may be improved by siliconizing the exterior surface. This may be accomplished by placing the finished mitts, with pads attached, in a tumbler, with a cloth or rag that has been impregnated with silicone.
  • halogenation may be accomplished by spraying a chlorine or bromine solution into the interior of the mitt after it is stripped from the former to halogenate the interior of the mitt without deleterious effects on the pad.
  • Interior surface characteristics may also be improved by application of a silicone spray to the former prior to application of a coagulant to the former before dipping of the former. Where this method is employed, the coagulant and silicone material must be compatible, such that neither will prevent the other from accomplishing its function.
  • the interior surface of the mitt may be provided with an irregular, rather than smooth, surface. The irregular surface may be provided by formation of a pattern of fine grooves and ridges on the former.
  • the pattern may, for example, be a herringbone pattern, a stippled pattern, or the like. It may be desirable to confine the pattern to the cuff portion of the mitt, i.e., the portion of the glove between the opening of the mitt and the hand portion, which covers the user's wrist. The pattern may be applied continuously to entirely cover the interior surface of the cuff portion.
  • the mitt When stripping the mitt, the mitt may be partially everted, with the upper edge of the mitt pulled down to strip the cuff portion of the mitt from the cuff portion of the former, and continued downward tensile loads may then be applied to the cuff portion, in some cases partially everting the hand portion and pad, until the entire mitt is removed from the former.
