Abstract

The invention relates to a control unit for thread feeding devices, such as those associated with knitting machines and the like. The control unit generates pattern or switch data control signals based on a pattern memory, or otherwise, for the thread feeding devices. In an embodiment of the invention, the control unit adds to or subtracts from the pattern data any advance or lag angles as necessary to account for the structure of the machine and to thus assure effective thread feeding.

Description

FIELD OF THE INVENTION[0001]The invention relates to a control device for at least one thread feeding device of a thread processing machine, especially a knitting machine. The invention also relates to a method for positive thread feeding to a textile machine, especially a knitting machine with changing thread requirements.BACKGROUND OF THE INVENTION[0002]Circular knitting machines and flat knitting machines are known, which are designed for stitching patterned goods. With respect to patterned goods, different stitching positions must be supplied with thread intermittently rather than continuously.[0003]One example of a circular knitting machine for creating patterned goods is seen in EP 0 724 033 A1. The circular knitting machine has a cutting device in order to cut away unnecessary thread. If thread of the corresponding color is needed again, the previously cut thread is fed again to the stitching position.[0004]In addition, a so-called striping attachment for a circular knitting ...
