ABSTRACT:
Tension is reduced in the unwound length of roving remaining between the drafting mechanism and the package after the frame has been brought to a halt. This can be done by additional feed from the drafting mechanism after stopping of the other elements of the frame. A tension adjusting means is coupled into the drive to the rollers of the drafting mechanism to advance the mechanism the desired amount. The degree of feed may be different depending upon whether the stoppage is due to a break at one of a group of flyers, or to a doffing operation.
