Description

Weft supply needle for ribbon narrow loom {WEFT INTRODUCTION NEEDLE FOR A RIBBON NEEDLE LOOM}

The present invention relates to a weft needle for ribbon narrow loom according to the preamble of claim 1.

First, the type of weft feeding needle mentioned is disclosed in CH 663 629 A. When weft feed needles are used on a ribbon narrow loom where the shed sill loops are bound by an auxiliary thread on the side facing away from the supply side, the two weft loops limb enter the operating range of the needle and are very limited. It leads to the disadvantage of being more difficult to bind in space.

The object of the present invention is to further improve the weft feeding needles mentioned earlier in order to avoid the above drawbacks.

This object is achieved by the features of claim 1. The guide element is arranged on the arm portion, on the side facing away from the guide bow, starting from the area of the hook and extending through only part of the length of the arm portion. The guide element forms a deflection point for deflecting the free limb of the cisyloop on the region facing away from the hook. The spaced limbs of the supplied weft-loops are deflected and do not enter the working area of the needle, so that the weft of the weft-loops can be satisfactorily secured by the auxiliary room, which can be achieved in a very limited space.

Advantageous improvements of the weft feed needle are defined in accordance with claims 2 to 6.

The arm element according to claim 2, wherein the guide element is disposed on the side of the arm portion in which the second guide bow faces away from the first guide bow, and engages over the hook, starting at the front end of the weft feeding needle, It extends over only a portion of the length and can be designed to connect with a connection point on the arm portion that forms a deflection point that deflects the spatial limb of the cisiloop.

In particular, a simple solution is described in claim 3, wherein according to the guide element, the guide element has a guide groove starting at the hook, extending over a part of the length of the arm part on the outside of the arm part and the curved surface of the arm part forming a deflection point. It is designed to be.

Depending on the structural conditions of the ribbon narrow loom, according to claim 4, an advantage can be obtained by allowing the guide element to extend over only one quarter or one third of the length of the arm portion.

It is basically possible to arrange the first guide bow at the top and the guide element at the bottom, but the construction of the weft feed needle according to claim 5 is characterized in that the first guide bow is arranged at the bottom and the guide element is arranged at the top. It can get more advantage.

Various configurations of the hook design are possible. However, according to claim 6, it is more preferable that the hook is designed to face the outside of the curved arm portion.

Figure 1 shows the floating area of the ribbon narrow loom. The warp yarn 2 is opened by a shedding device, not shown in detail, into the shed in which the weft loops 6 of the weft yarns 8 supplied later are supplied by the weft feeding needle 4. On the side facing away from the supply side, a needle 10 for floating the auxiliary chamber 12 together with the weft loop 6 is provided to secure the weft loop. The secured weft loops 6 are beaten at the biting-up edge 16 by the leads 14, resulting in the ribbon fabric 18 being made.

Weft feed needle 4 is shown in more detail in FIG. 2. The weft feeding needle 4 has a curved arm portion 20 connected at one end portion 22 with the drive element 24 of the ribbon narrow loom. A hook 28 that holds the weft loop 6 is arranged at another distal end 26. The arm part 20 has a lower first guide bow 30 which extends substantially over the entire length of the arm part, which receives the at least one weft 8 together with the arm part. The slot 32 is formed. At the distal end facing the hook 28, the guide bow 30 is connected to and fixed to the arm portion 20 via the connecting portion 34. As shown in FIG. On the side facing away from the 1st guide bow 30, the 2nd guide bow 36 which is a guide element is arrange | positioned. The second guide bow 36 is coupled to the hook 28, one side is fixed to the front end of the weft supply needle, preferably to the connecting portion 34 of the first guide bow 30, the other side is the arm portion ( And extends over a length of 20), for example a portion of one third to one third. In the fixed portion, a deflection point 35 is formed to deflect the spatial limb 38 of the cisyloop 6. The length of the second guide bow is selected in such a range that the spatial limb of the weft loop can not enter the operating area of the needle.

In particular, as shown in FIG. 1, the second guide bow 36 steers the spatial limb 38 of the weft loop 6 to the outside of the operating area of the knitting needle 10 so that the auxiliary chamber 12 is internally located. The space limb 38 is not caught when it is displaced from. In the absence of the second guide bow 36, the spatial limb of the weft loop 8 will follow the path portion 38a, as indicated by the dashed lines (in the figure), in the operating area of the needle 10. It is more difficult to securely bind the weft loop 6 with at least the auxiliary chamber 12 at the end. A plurality of wefts 8, 8a, 8b are supplied through the guide member 40 in the slot 32 of the first guide bow 30, and as known in the art, the hook 28 of the weft feed needle Figure 1 shows that it can be selectively engaged with.

3 to 5 further illustrate a representative embodiment of the weft feeding needle 4a corresponding to FIGS. 1 and 2, wherein the same members are given the same reference symbols. In the weft feeding needles of FIGS. 3 to 5, the guide element begins at the hook 28a and extends over a portion of the length of the arm portion 20, with the extended surface being in particular spaced apart from the guide bow 30. It is designed as a guide groove 42 formed outside of 20). The selected weft 8 is lifted from the region of the connection portion 34 outside the lower slot 32 to the upper region of the hook 28a to enter the hook 28a. When the weft feeding needle 4a swings into the shed, the weft 8 is guided to the guide groove 42, and the curved surface of the arm portion 20 deflects the deflection portion 35a which deflects the weft limb to the length. It does not enter the operating area of the needle.

Additional advantages and modifications are readily applied in this technical field. Therefore, from a broader perspective, the present invention is not limited to the described embodiments and the described exemplary embodiments. Accordingly, various modifications may be made without departing from the scope of the general inventive concept as defined by the appended claims and their equivalents.
