Definitions

  • the present invention relates to an elongated pile sub- assembly, pile sub-assembly articles and a guide apparatus that is useful for the purpose of making a brush, or making a pile or bristle surface structure such as a floor covering, a wall covering or an automotive component. More particularly, the present invention concerns an elongated pile sub-assembly have a "root" end for secure anchoring of the elongated pile sub-assembly on or through a substrate.
  • a "U” shaped tuftstring for wall or floor coverings is normally attached to a backing structure first, to form a pile fabric or carpet.
  • the point of attachment for the "U” shaped tuftstring is at the bottom of the "U” shape, which is also where the yarn and the support beam bond to one another.
  • This bond area is generally a solid mass of fibers fused together providing only a small surface area to contact with and bond to a support substrate.
  • the bond between the "U" shaped tuftstring can be formed using a thermal or solvent fusing process, adhesives, or mechanical interlocking means. This small contact area generally produces low "tuft- lock” values (e.g. the force at which the bond fails). Additionally, the rounded bottom of the "U” is susceptible to rotation (see Figs.
  • elongated pile sub-assembly that has a high "tuft-lock" value, controlled wicking and vertical alignment.
  • a low-cost elongated pile sub-assembly containing bundles of fibers arranged to provide a high density, that can be made by a simple, inexpensive method, and is designed to be packaged, or used directly as a feed material for making a brush or a pile/bristle surface structure.
  • a strong, reliable elongated pile sub- assembly that can be packaged and handled in a fabrication process. It is also desirable to have a guide apparatus to bond the elongated pile sub- assembly to a substrate.
  • a pile or bristle surface structure comprising: a substrate, and an elongated o pile sub-assembly secured to the substrate.
  • Figs. 1 B and 1 C are elevational end views of the prior art showing visible defects resulting from "U" shaped tuftstring rotation;
  • Fig. 6 is a diagram showing one way to measure the diameter 5 of a pile yarn
  • Fig. 9A is a diagrammatic view of a simple process for making the elongated pile article of the present invention.
  • Fig. 13 is an end elevational view of an embodiment of an 5 elongated pile sub-assembly bonded using an ultrasonic weld;
  • Fig. 18A and Fig. 18B show elevational views of two embodiments of an ultrasonic horn used for bonding in the present invention. 0
  • the base portion of the "U" shaped tuftstring may roll or rotate as it is guided and secured to the backing. More friction on one bundle segment 109b than on bundle segment 109a, for example, would generate a torque and cause the "U" shaped tuftstring to rotate counter clockwise as shown by arrow 103a (see Fig. 1B). Another cause can be attributed to an uneven substrate surface such as when a reinforcement fiber is present and generates a ridgeline 105a on the surface.
  • a torque force is again established when the velocity or motion is normal to the plane of the substrate and can cause the tuftstring to rotate or lean.
  • the leaning effect shown in Fig. 1C can also cause a space 132 between the tufts which creates an undesirable spacing defect or at least causes density variations in the finished pile.
  • Figure 4 shows an end elevational view of an elongated pile sub-assembly with the short filament bundle segment 127 having surface flaring 129 in the adhesive 117.
  • the short filament bundle fibers are totally encapsulated for a strong anchoring of the elongated pile assembly 125.
  • Another variation, not shown, is where all the roots 127 of Figure 2 lay horizontally to one side.
  • the ultimate position of the roots of the tuftstring is mostly dependent on the characteristics of the substrate and the stiffness of the root filaments. An open, non-woven substrate would easily permit the roots to penetrate the fabric structure without much deflection of the roots as shown in Figure 2A.
  • an elongated pile sub-assembly may be mounted on the core 314 in an alignment in which the elongated pile sub-assembly is longitudinal, i.e. parallel to the centerline axis of the core, or in an alignment in which it describes a circle about the longitudinal axis along the circumference of the core, or in other variations on any of such alignments as described.
  • Elongated pile sub- assemblies may be secured to the core in parallel alignment to each other.
  • the shorter bundle segment of the elongated pile sub-assembly may be secured to the surface of the core; or the elongated pile sub-assembly may be secured to the core by a bond between the core and the support beam, or a bond between the core and portions, or all, of both the shorter bundle segment and the support beam.
  • the shorter filament segments may become the point of contact for the application of adhesive between the substrate and the elongated pile sub- assembly, forming an adhesive bond between the substrate and the shorter filament segments, or the shorter filament segments may be the location of, and be contacted with, a zone of polymer flow.
  • the shorter filament segments act as roots in these embodiments, ensuring a solid bond between the elongated pile sub-assembly and the substrate.
  • the rooted tuftstrings can be attached to sheets of polymer with relatively "solid" surfaces such as sheets made of epoxy 5 resins, thermosets, thermoplastics, wood, and even metal. (Some of these methods of attaching require the use of adhesives.)
  • an alternative to wrapping the elongated pile sub-assemblies spirally, as shown in Fig. 15, is to make a pile surface structure by creating an array in which one or more elongated pile sub- assemblies are, for example, in parallel alignment to each other and brought into contact with a bonding surface of a backing substrate.
  • a typical set-up would position the guide 90 with an elongated pile sub-assembly 125 threaded into the guide 90 over the flat substrate with a minimal gap between the bottom surface of the beam and the substrate to substantially splay the short segment filaments 127 without causing binding of the elongated pile sub-assembly 125 as it passes through the slot 97 of the guide assembly 90.
  • the rooted tuftstring pile articles are continuously supplied from one or more rooted tuftstring machines or from an inventory on spools.
  • the elongated pile sub-assemblies are directed by rolls and guide pins (not shown) into the grooves of the guide with the short bundled end extending outward therefrom.
  • the guide mechanism guides a plurality of individual short bundle segments of elongated pile sub-assemblies into contact with the preferably continuously fed backing substrate.
  • An adhesive material such as a thermoset or thermoplastic adhesive is 5 applied to the surface of the substrate just prior to passing under the guide assembly. Ideally, the linear rate of the process and the heat capacity of the adhesive is adequate to achieve good wetting and encapsulation of the short fiber segments prior to bonding with the substrate.
  • the adhesive is cooled as it passes under the guide assembly 0 such that at the exit of the guide, the rooted tuftstrings are unable to reposition themselves.
  • FIG. 17 Another process embodiment of the present invention is o shown schematically in Figure 17.
  • the short segment fibers 127 of the elongated pile sub-assembly 125 face toward the bonding element (e.g. adhesive applicators 95) as the elongated pile sub-assembly are feed through the guide 91.
  • the short bundle segments of the elongated pile sub-assembly preferably wipe the adhesive from the applicator end and 5 the elongated pile sub-assembly continuously wipes the guide surface to avoid a large build up of adhesive in the guide as the elongated pile sub- assembly is feed through the guide.

Abstract

L'invention concerne un sous-ensemble velours allongé comportant un montant de support destiné à fixer une pluralité de faisceaux de fils. Chaque faisceau de fils fixé sur ce montant présente une extrémité velours et une extrémité base destinée à ancrer les sous-ensembles velours allongés. Les extrémités bases peuvent également entremêler leurs bourres pour améliorer le support d'ancrage du sous-ensemble velours allongé. Un ensemble de guidage est utilisé pour former un article en cordon de touffes enracinées, tel qu'une brosse ou un article de revêtement de sol. Le sous-ensemble velours allongé selon l'invention peut être utilisé seul pour fabriquer une brosse ou une structure de surface en crin ou en velours, telle qu'un revêtement de sol, un revêtement mural ou un composant pour automobile, ou il peut être disposé avec d'autres articles velours allongés, et fixé sur un substrat de support, comme par exemple lorsqu'il est utilisé pour fabriquer une structure de surface en velours ou en crin. Une brosse ou une structure de surface en velours peut être fabriquée à partir d'un seul sous-ensemble velours allongé, ou à partir d'un sous-ensemble velours associé à un élément de corps de brosse ou à un substrat de support.
