Controlled thread guides for a weft thread magazine

摘要

A weft thread magazine operates in a warp knitting machine having a needle bed. This magazine includes a pair of endless transfer chains, each having a plurality of holders for retaining weft threads in parallel and for delivering them to the needle bed. Also included is a thread laying arrangement operable to transversely reciprocate between the transfer chains and to transport weft threads from one chain to the other. The arrangement also includes a carriage having a plurality of thread guides for transferring weft threads around the holders as the thread laying arrangement reverses direction. These thread guides can reciprocate between an operative and inoperative position. In the inoperative position, the thread guides are precluded from transferring thread to the holders. The magazine also includes a control device for moving the thread guides between the operative and inoperative position.
