Object of the invention

The aim of the invention is therefore to improve the quality of the pile loop knitted fabrics that can be produced on crocheting machines. in particular with regard to the mesh tear resistance in order to achieve a simpler finishing of these goods and to open up new areas of application for them.

Explain the essence of the invention

The object of the invention is to G-round, in a pile loop knitted fabric of the type mentioned in the introduction in an uncomplicated manner, the mesh resistance of the fabric base with the help of the pile thread to increase and to provide a method and a crochet galloon machine for the production of such goods. This object is achieved according to the invention in that the pile thread at least in the predominant part of those courses of stitches in where it is tied between the needle and sinker stitches in the same way as the warp thread and forms an open loop in the stitch, which is partially drawn through to the right side of the goods. This loop of pile thread material pulled through the mesh practically prevents the loops from running if the binding warp thread breaks, as it does not jump over the loop can.

According to a further feature of the invention, the pile thread is voluminous and elastic in order to increase the stitch resistance. The pile thread advantageously consists of an effect yarn in which the thread core is shorter than the thread surrounding the thread core. A method of making the stitches of the present invention Pile loop knitted fabric on a crochet galloon machine with a row of crochet hooks, one of which is the binding warp threads leading guide bar, at least one guide bar for the pile threads, weft thread guides and arranged between the needles Pole sinkers is characterized according to the invention in that the

Pile threads in the same layer as crochet hooks in every second row of stitches are presented to the knitting thread and clamped by the binding warp thread on the shaft of each needle, and when the needles are withdrawn under Maintaining the clamping - with the gill parts on the shaft the needle moves up to the hook - each an open loop of pile thread material is formed from a thread reserve that is at least partially pulled through the formed loop on the right side of the knitted fabric during the knockdown. A crochet galloon machine for carrying out the method according to the invention, for which the machine has a binding warp thread guide rail, at least one thread guide, which is a series of Polschi ingenhalt em is assigned, partial wefts covering weft thread guides and printing sinkers, all with a number of Crochet needles work together, with a weft thread guide being provided for each crochet needle division, and the associated pressure plates are raised and lowered in recesses serving as guides of the respectively assigned pile loop holder, is according to the invention characterized in that sinkers are provided in the needle gaps below the needles in front of the pile loop holders that can be raised and lowered to deliver the thread reserve for the formation of the loop of pile thread material.

According to FIG. 1, the crochet galloon machine has a number of crochet needles 1, the hooks 2 of which by means of a binding warp thread 4 leading guide rails 3 are occupied, these threads usually to a fringe binding or to simple crochet stitches are processed.

The crochet hooks 1 are held in a bar 5 and guided by a comb 6, which for this purpose is at its upper end has corresponding recesses 7.

Between every two crochet hooks 1 or per needle division there are two PoI loop holders located one behind the other in the longitudinal direction of the needles 9; 10 arranged at a distance from one another and from the comb 6. The pile loop holders extend so far below the crochet hooks 1 that they are able to take up some pile loops 11; 12 before the one taking place in the direction of arrow A. Withdrawal, the double-sided pile loop knitted fabric 13 is freed from the holders 9; 10. The pile loop holders are above the crochet hooks 1 9; 10 at a greater distance from each other than under the crochet hooks 1 each attached to a bar 14; 15 so that in the room a rail 16 is provided from one bar 14; 15 to the other could be, which is equipped with weft guides 17 extending in the direction of the crochet needles 1. The weft guides 17 each have a thread guide tube 18 at their free end. In the case shown, the rear row is used Pole loop holder 9 as a guide means for the printing plates 19, which are seated on a bar 20. The crochet galloon machine is also equipped with as many weft guides 17 as there are crochet hook divisions »for binding of two thread systems there is a guide rail 21 in front of the pile loop holders 10 and behind the pile loop holders 9 a guide rail 22. Both guide rails 21; 22 are with Pile thread hole needle.ln 23; 24 equipped. Furthermore are in the needle gaps provided below the needles 1 in front of the pile loop holders 10 sinkers 25, which are in a bar 26 that can be raised and lowered held v / ground. (Fig. 1)

At the beginning of the seven-cycle cycle, the front pile thread hole needle is at a standstill 24 under the crochet hook 1 (Fig. 2 and 2a). Then the pile thread hole needle 24 goes up and swings over the shaft of the corresponding crochet hook 1. The pile thread 27 wraps around the upper one Position "located board 25 and is on the shaft of the needle 1 as a result of the stroke of the guide rail 3 through the binding warp thread 4 clamped (Fig «3 and 3a).

When withdrawing the crochet hooks 1 comes due to the specific Formation of the threads 1 (according to DWP 29 378) only the correspondingly presented binding warp thread 4 in the hook 2 of the Needle 1, the clamping of the pile thread 27 being maintained by the clamping point from the shaft of the needle 1 to the Hook 2 of the same migrates (Fig. 4 and 4a). When the needles 1 retract further, the sinker is first 25 lowered, whereby a certain reserve of pile thread material is made available that the maintenance of the Clamping of the pile thread 27 by the binding warp thread 4 on the hook of the needle 1 until the old stitch 28 is knocked off (Figures 5 and 5a).

When the old mesh 28 is knocked off, the open Loop 29 (Fig. 5 and 5a) partially pulled through to the right side of the V / are · As a clamping of the pile thread 27 on the shaft the needle 1 or its hook 2 only arrives when the binding warp thread 4 is placed in the same position as the pile thread 27, can repeat this process only in every second row of stitches, which is why the bar 26 carrying the sinker 25 only in each second machine tour is raised »

The Polschlingengewirke according to the invention, Fig _# 6 · Den Gewirkegrund form the group consisting of the binding warp yarns 4 wales of Häkelmaschen and that of the weft yarn guidebooks. 17 and the printing sinkers 19 weft threads 30 placed under four crochet needles each, which are enclosed by the needle loops 31 and the sinker loops 32 of the binding warp thread 4.

909830/0579

The ones from the pile thread needles extend from one crochet stick to the immediately adjacent one 24 originating, pile loops forming pile threads 27 integrated so that they lie over the weft threads 30 and the front side of the goods, each pile thread 27 forms in each stitch row in which it is the same as the binding warp thread 4 between Needle stitch 31 and sinker stitch 32 is tied, an open loop that partially extends to the right side of the Pile loop knitted fabric is pulled through. This through the mesh loop 29 drawn through practically prevents the loops from running if the binding warp thread 4 breaks, since the same cannot jump over the pile thread loop 29, especially if the pile thread material used is right is voluminous.

It should also be noted that the thread hole needles 23 originating pile loops representing the rear side (right side) of the goods are not shown in FIG. 6 for the sake of clarity became. They are provided analogously to the pile loops 27, but on the other hand lie under the weft threads 30, so they hang practically in the needle stitches 31 of the binding warp thread 4 and are formed without the loops 29.

Finally, it should be noted that the maintenance the clamping of the pile thread 27 by the binding warp thread 4 on the shaft or hook 2 of the needle 1 is required A thread reserve does not necessarily require the presence of an additional aid such as the plate 25. If the pile thread is elastic and consists, for example, of an effect thread whose thread core is shorter than the thread surrounding the thread core, it is maintained due to the elasticity inherent in the pile thread the clamping of the pile thread 27 by the binding warp thread 4, i.e., which is used to maintain the clamping of the pile thread 27 on the Needle 1 required thread reserve then results from the Structure of the pile thread material
