ABSTRACT:
The disclosure relates to a system and method for correlating strand withdrawal speed from a strand supply package and utility means such as a shuttleless loom thereby reducing the possibility of supply package sloughs and strand breakage caused by conditions such as large changes in loading on an intermediate stationary drum type strand feeding and storage device. Thus, the loom operates to withdraw strand from the feeding device at a first average rate. A flyer withdraws strand from the supply package at a second rate which is slightly higher than the first average rate and wraps that strand onto the drum of the feeding device. Withdrawal of the strand by the flyer generates a balloon in the strand intermediate the strand supply and the flyer. Flyer drive speed is controlled by a feedback system which avoids changes in speed of the flyer except when occurrences of an overfill of strand on the drum occur. An overfill detector is provided for the drum and operates an on-off circuit in response to detection of an over-accumulation of strand on the drum to interrupt current flow to the flyer drive. When the overfill condition is relieved current is restored to the flyer drive. The frequency and duration of current interruptions is controlled so that the balloon of strand between the strand supply and the flyer is maintained at all times when the loom is operating. Consequently, strand sloughs and strand breakage which could result from frequent starts and stops of the feeding device are avoided. The system and method are equally applicable to strand feeding devices of the rotary drum type, in which case the motor is employed to control drum drive speed.
