Patent DE-2345986-A1 (DE)
Title: Yarn feed device having reserve winding on drum - with movable guide to prevent or allow yarn to be pulled axially from the drum to provide two feed rates
Inventor: JACOBSSON KURT ARNE GUNNAR
IPC: B65H51/22
Filed: 1973-09-12
Abstract: A reserve winding of yarn is formed on a drum and a yarn guide which is open in the direction in which yarn is supplied to the drum, and which is pref. pivotal on an arm at the side of the drum surface about an axis parallel to the drum axis, is movable to engage the yarn adjacent the lower end of the drum. When the yarn guide is disengaged from the yarn, the yarn can be pulled axially off the lower end of the drum and fed rapidly to e.g. a knitting machine, while when the yarn guide engages the yarn it prevents the yarn from slipping axially from the lower end of the drum so that the yarn delivery speed from the drum is limited by the rate at which yarn is wound onto the drum. The drum may be rotatable or stationary, and in the latter case the yarn is pref. wound onto the drum by an orbiting, yarn guide. The device is of simple construction and all parts are readily accessible.
