Title: Yarn feeding and changing apparatus for circular knitting machine
Inventor: SAWAZAKI MASATOSHI
IPC: D04B15/54
Filed: 1986-02-28
Abstract: An individual yarn clamping and cutting device 19 is provided for each yarn guide 16 and is moved to an open position, e.g. by a pawl 26, in response to movement of the yarn guide from active to inactive position.
