Device for producing a thread formed from stitches of an auxiliary thread Edge on fabrics

The invention relates to an apparatus for manufacturing an edge formed from meshes of an auxiliary thread on fabrics, in particular on fabric tapes that protect on loose looms are made, in which the ochuß in Loop shape is entered by means of a reciprocating insertion needle.

Known devices of this type, as described, for example, in US Pat. No. 3,064,689, have a rather complicated structure in order to ensure that the covering thread is looped around the edge needle which is used for stitch formation. Other devices such as the UIi -Fabrics 1 296 o? 3 and 1 6o4 36.3 are described ,, have the following caution "With the last-mentioned caution lafc a guide ν Γίϊ.Ί. * the Hllfofadan erfo: cdtiTli ':: h, tuu; · for eich tuid like au «ü * ;; -« borrowed from the work of the web /:.

The object of the invention is to create a simple structure for a device of the type described, whereby the vote of the thread guide for the auxiliary thread on the loom speed is reached automatically ο

This object is achieved according to the invention in that the thread guide of the auxiliary thread is attached to the slack of the loom, while the edge needle, which moves back and forth approximately in its longitudinal axis, is approximately parallel to the fabric plane in a vertical longitudinal plane between the side hand of the fabric and the thread guide so is arranged that this is with the retracted L _a de below the edge needle and on the other hand above the same when the needle is advanced against the finished tissue «.

Another advantage of the invention is to see that with the device a simple edge with stitches formed by the auxiliary thread alone or a fixed stitch edge can be formed, the stitches both from the auxiliary thread and from the Weft thread »

On the side of the fabric 28 opposite the holder 34 for the insertion needle 32, a needle 36 for edging is arranged in a plane which is essentially parallel to the horizontal plane of the fabric has proven. A thread guide 38 for the auxiliary thread 4o is attached to the drawer 22, specifically on the side opposite the holder 34, and serves to guide the auxiliary thread 4o at an angle to the hand 26 of the fabric 28, as shown in FIGS. 1 and 7 to 14 can be seen · The edge needle 36 is inserted into a needle holder 42, which is seated on a fork piece 44, to which one end of a length-adjustable rod 46 is connected, see Fig. 3ο The other end of the rod 46 is with the pin 49 of a crank mechanism 48 connected. The fork piece 44 with the needle holder 42 is connected to two parallel links 5o, 5o ^f , the other ends of which are hinged to the loom frame. When the crank drive is running, the rod 46, the fork piece 44 and the edge needle 36 are curved upwards, forwards and again moves downwards when the needle advances towards the back of the loom, see Fig. 3 »The needle holder 42 with the edging needle 36 returns on this curved path when they move towards the front of the loom * This path the edge needle 3 & is necessary so that it remains at a distance from the incoming leg of the BehuSfadenschiaufe and still won _?

In the position of the drawer 22 shown in full lines in FIG. 2, the auxiliary thread 4o assumes its lowermost position, while the drawer 22 is here in the position in which the insertion needle 32 enters the compartment formed by the warp threads 24 to insert the front leg 3o ^f (FIG. 12) of a loop of the weft thread Jo and the edge needle 36 passes transversely over the weft thread leg 3o 'and the auxiliary thread 4o, as can be seen from FIGS. 7 and 11. Is the load 22 to move to its pre-M particular position, as in Fig. 2 indicated by broken lines, the auxiliary yarn is 4o raised to a position at ~ Q

which it lies above the horizontal plane of the fabric 28, as a result of which the auxiliary thread 4-o is guided against the edging needle 36 and in its hook, as can be seen from FIGS. 8 and 12. After the auxiliary sf threads 4o is inserted in the hook of the edge needle 36, the edge needle 36 is in its retracted position shown in FIG _e 3 and 1o, giving, where 4o pulls the auxiliary yarn to form a loop "Fig. 14 shows the corresponding Torgang, wherein but for knitting the auxiliary thread 4o with the weft threads 3o loops both from the weft thread and from the auxiliary _

thread to be pulled. "

7 to 10 show successive stages when forming an edge knitted from the auxiliary thread 4o alone, the stitches through the weft thread loops be pulled through so that they cannot be pulled out of the tissue 28. This type of edge is true not mesh-proof, but has proven to be very useful for many narrow fabrics. With this type of edge it is essential that the weft loops are not caught by the hook of the edging needle 36. The movements the insertion needle 32 and the edge needle 36 must therefore be matched to one another in order to ensure that the weft thread 3o when forming a loop around the Shank of the edged needle 36 pulled below the tongue

as can be seen from FIG. The relative movements the insertion needle 32 and the edge needle 36 are adjustable, as shown in FIGS. 4 and 5, which is "described" in more detail below,

11 to 14 show successive stages in Forming a fixed stitch edge which is knitted from both the auxiliary thread 4o and the weft threads 3o, by looping the weft thread above the tongue around the Edge needle 36 are pulled so that the weft thread 3o is caught by the hook of the edge needle 36 »Here are then loops of the weft thread and loops of the auxiliary thread through previously formed loops of the Weft thread and auxiliary thread pulled through.

The edging device can be adjusted that either the simple edge by means of the knitted auxiliary thread according to Fig. 7 to 1o or the stitch-fixed edge according to FIGS. 11 to 14 is produced, in which the auxiliary thread and the weft threads with one another are entangled · One of the two settings according to Fig. 4 or 5 is used for this · In Fig. 4 the length of the V / eg on which the edge needle 36 advances, determined by the stroke of the crank drive 48. This stroke is itself on the distance of the crank pin 49 from the center The crank pin 49 is located in the position shown in FIG. 4 position shown and the path of movement of the insertion needle 32 is not changed, the device is a simple edge formed by means of the knitted auxiliary thread 4o. If, however, the crank pin 49 takes its place 54 is set and remains the trajectory of the insertion needle 32 unchanged, a fixed mesh edge is created, in which the auxiliary thread and the weft threads together are entangled ©

Fig. 5 illustrates another setting to to change the type of edge created «The entry needle 32 is adjustably mounted on the needle holder 34 so that it is either the fully extended position or the dashed line Position · Is the insertion needle 32 in the fully extended position and the edge nn ade lan drove in the position shown in Pig * 3 and 4-, in this way the mesh-proof edge according to FIGS. 11 and 14 is produced. If, however, the insertion needle 32 is in the dashed line Position after Fig. 5 offset and "remains the edge needle drive unchanged, becomes a simple edge according to Fig. 7 ^ is produced because the weft cord is underneath the tongue is looped around the shaft of the edging needle 36 o

It can thus be seen that the path of movement of the insertion needle or the edge needle drive is either alone or can be adjusted together to make the weft loop either above or below the tongue of the To create an edging needle, so that a single or a fixed-knit Edge can be created as desired, whereby the timing of the movements of the girls in the must be precisely adjusted in the usual, well-known manner «

As can be seen from FIG. 6, the Santennadel 36 is in the generally rotated so that their beacons are below the horizontal opens · It has been found to work very well is obtained when the hook is within the 9 © ° -% iÄdra3atesi opens, the through. ü @ »Begem 5β la Fig * 6 says let «you tilt the Kaat # sas & * l 36 .kaaa © about 4 «? ° amount to * - ■
