In a crochet galloon machine, the needles (11) are fastened to a needle bar (12) reciprocated by at least a connecting rod (20) for the control of needles, operatively engaged with a needle control eccentric (21) carried by the rotary main shaft (22). Associated with the needles (11) are closure latches (13) fastened to a thrust bar (14) integral with at least a rod (18) carrying out a reciprocating movement upon command of a rocker lever (29) the opposite ends of which are fastened to respective connecting rods (30) for the control of latches (13). Each connecting rod (30) is driven by a latch control eccentric (31) operated by the main shaft (22).

Crochet tools for producing bands on a crochet galloon machine. For the production of thin bands on ten or more crochet needles (10, 10') per centimeter of width, the stems of the crochet needles (10,10') are clamped over more than half the length of the needle. A knocking-over bar (20) fastened to the machine has a free straight edge (66) which adjoins closely but without play those parts of the crochet needles (10,10') which project out of the clamp device. The crochet needles are clamped with adequate security against lateral bending. There is no friction between the crochet needles at the knocking-over bar (20). The crochet needles can be clamped in groups, so that they stiffen one another. For the feeding of elastic threads use is made of combs (6) which are displaced laterally to-and-fro relative to the crochet needles in the working rhythm, but which are disposed at a uniform height relative to the crochet needles.

Installed on a crochet galloon machine is a device (1) for inserting alternately-interposed wefts, comprising two weft-inserting sliders (10, 16) carrying respective threading tubes (11, 17) each adapted to lay down a weft yarn (12, 18) to be interlooped in the article of manufacture (M) being worked. Each slider (10, 16) is movable along a respective weft-inserting guide (9, 15). The cyclic movements of the sliders (10, 16) are mutually offset according to a cycle fraction equal to the number of the provided weft-inserting bars (9, 15), so as to alternate laying down of each weft yarn (10, 18) with each chain stitch (6b)-formation cycle.

A crocheting machine has slide needles (2) with knitting needles (4) which are disposed on a knitting needle bar (6). Slides (8) of the slide needles (2) are attached at a slide bar (10) which is disposed over the knitting needle bar (6). Thus, a simple and rugged construction for the crocheting machine is obtained.

The invention is directed to a process and a device for the production of textile net-like fabrics by various bonding processes, e.g., the warp knitting process or stitch bonding process. Based on the object of the invention--to provide a process and a device for carrying out the process for producing textile net-like fabrics with threads which are continuous in the working direction and transversely thereto and which form mesh sides of the net, with large mesh widths, a high variability of structure, and product widths extending beyond the working width --a plurality of adjacent groups (4) of mesh side threads forming the mesh sides in the working direction are produced, a function thread (12) is guided from one longitudinal side of the fabric to be produced to the opposite longitudinal side of the fabric to be produced in order to form the other mesh side lying transversely to the working direction, the function thread is temporarily set in its position transversely to the working direction at least at two setting points arranged adjacent to one another transversely to the working direction, the function thread is formed into at least one loop in order to form function thread reserves (13) between two setting points arranged transversely to the working direction, the function thread which is provided with at least one function thread reserve and is temporarily set transversely to the working direction is tied on or tied in at the same time at least at two adjacent groups of mesh side threads, and the temporary setting of the function thread is canceled.

The device herein described comprises a pair of pulling rollers 3 which engage a manufactured article 4 produced by knitting members 5 acting upstream of the pulling rollers themselves, in order to interlace weft yarns with warp yarns 4a. A first driving mechanism 6 connects the pulling rollers 3 to a rotating main shaft 7, so that the pulling rollers too are rotated in order to pull the manufactured article apart from the knitting members during the operation of the loom. The device further comprises feed rollers 17, 18 rotated by a second driving mechanism 22 connecting them to the first driving mechanism. Feed rollers 17, 18 act upstream of the knitting members, upon the warp yarns 4a to move them forward towards the knitting members 5 and give them an appropriate tensioning.

The thread processing device (8) of a textile machine has at least one thread guiding device that moves a thread (4) back and forth between at least two positions (12, 14) by means of a thread guiding member (30, 32, 34). The thread guiding member may be moved in one direction by means of an interlocking drive (28) and in the opposite direction by a frictional engagement drive (36) that acts against the interlocking drive (28). The textile machine is substantially improved by designing the frictional engagement drive (36) as a pneumatic drive with an individual gas chamber (64) that contains a gas volume that may be compressed by the interlocking drive at the working frequency. The gas chamber communicates with a compressed gas source through a non-return valve.

A thread control device of a weft knitting machine comprises a thread guide, which is fastened to a weft rod. The weft rod is mounted to be pivotable about its longitudinal axis and to be axially displaceable in supports, which in turn are movable at right angles to the axis. The weft rod is connected to be secure against rotation with a non-axially displaceable crank. A non-rotatable drive transfer member is reciprocatingly displaceable in a plane parallel to the axis by, for example, a pivot arm. A thrust member is articulated by ball joints to the crank and to the transfer member and in operation converts reciprocating motion of the transfer member into oscillatory pivotation of the crank. Such a thread control device makes high operating speeds possible and enables production of tapes with complicated patterns. The pivotation can be produced and controlled by a dog chain guided over a cylinder, which can guide other dog chains for displacement of additional weft rods and the axis of which extends at right angles to the weft rods.
