Description

Jacquard flat knitting machine The invention relates to a jacquard flat knitting machine with an optional either to transfer the stitches from the needles of the one on those of the other bed or device suitable for ordinary knitting, two opposing pairs of locks on the feet of the same height Needles, jacks and auxiliary jacks work around the needles for knitting or for looping stitches to move differently.

It is known in jacquard flat knitting machine with a device for stitch transfer to arrange loading sondere Stößer- and needle raising cam to the stitch transfer in Stößerschloß and for stitch transfer in the needle cam, in each case in combination with the Stößer- and needle jacks which determines to perform the knitting movement are.

There are also knitting machines with a device for stitching known, in which combined needle lifters are provided between the needle countersinks for advancing needles with different foot heights in order to achieve different large feed rates for knitting and stitching movements.

The invention is based on the object of a jacquard flat knitting machine of the type mentioned at the beginning, the stitching of needles on one bed Needles of the other bed without complicated lock parts and without an extension the opposing normal ones required for ordinary stitch formation To enable lock pairs.

According to the invention this object is achieved in that for hanging the mesh of each opposing pair of locks in the area between the usual, has adjustable needle countersinks in their lock plates retractable needle lifters, who are out of action while knitting.

The needle lifters for each lock pair are expediently at the same time with one another can be moved in and out of working position.

Furthermore, the needle lifters advantageously have the needle bed surface on their surface facing side a straight, unstepped surface.

The invention is based on an exemplary embodiment of the lock pairs in connection with a jacquard flat knitting machine and with cover explained in more detail on the drawing.

The drawing shows the two lock pairs I, II of the jacquard flat knitting machine, namely the lock pair I during the slide stroke from right to left during a Knitting row for patterned pressed goods, and the pair of locks II during the carriage stroke of left to right during a stitch transfer row from the needles of the rear onto the needles of the opposite front needle bed.

With A the needle locks are designated, which between the usual Needle countersinks are not needle lifters for shifting the needles according to the knitting, but only have retractable needle lifters 6, 7 for stitching. With B they are common ram locks and with C the common auxiliary ram locks.

The fixed lock parts are shown hatched. The countersink are adjustable according to the arrows and the other lock parts are in the lock plates retractable. The lock parts in the working position are fully extended shown, while the out of work lock parts are dashed are shown.

1, 1 ', 1 ", 2, 2' etc. denote the dash-dotted through lines of the needle, ram and auxiliary ram feet when walking through the locks concerned, the reference numbers referring to the following positions: 1 out of business, 2 catch, 3 stitch formation, 4 stitches transfer, 5 stitches transfer. The stitch transfer and stitch takeover needle levers 6 and 7 are arranged in the area between the two conventional needle cores and can be lowered into the lock plates, whereby they are brought into and out of working position with one another by means of conventional control elements.

The needles intended for knitting are replaced by those of a conventional one Jacquard device selected pusher without a needle lifter directly into the specific Catching or stitching position advanced and then by means of the usual Countersink lowered into the starting position (lock pair T - slide stroke from right to left).

Should now the stitches of the selected jacks or the related Needles of the rear needle bed on the opposite needles of the front needle bed are reassigned, for the time being the usual control organs are used to control the mesh transfer and To move stitch take-over needle lifter 6, 7 (lock pair 11) into working position. During the subsequent slide stroke, from left to right, the pushers bring their Needles or their feet in engagement with the in the area between the two needle countersinks arranged needle lifters 6, 7 for looping stitches.

From the above it can be seen that in the two according to the invention Pairs of locks that are used for knitting or for knitting stitches on a jacquard flat knitting machine are determined in the needle locks in the area between the two usual needle countersinks only needle lifters for stitching and no needle lifters for knitting are.
