Abstract

LOOM STORAGE FEEDER IMPROVEMENT The disclosure relates to a system and method for matching yarn withdrawal speed from a yarn supply package and utility means such as a shuttleless loom thereby reducing the possibility of supply package sloughs and yarn breakage caused by conditions such as large changes in loading on an intermediate rotary drum type yarn feeding and tensioning storage device. Thus, the drum of the storage device is driven by a d-c motor controlled to provide a constant drum drive speed thereby withdrawing yarn from the supply package at a constant rate. said rate is slightly higher than the consumption rate of the utility means. The drum speed is maintained constant by a feedback system which avoids changes in speed of the drum except when occurrences of an overfill of yarn on the drum occur. Thus, a constant speed drum drive system in this invention replaces variable speed or constant torque drum drive systems of the prior art which drive in relation to loom consumption resulting in frequent storage feeder stops and starts which in turn result in package sloughs and/or yarn breakage.
