ABSTRACT:
In a method of chopping fiber from a leg containing three or more fiberizers, prior to stopping the chopper for maintenance all of the strands are first removed from the chopper and put into a single set of pull rolls located near the chopper where the strands are pulled while the chopper is down. When the chopper is started back up the strands are more quickly started back into the chopper avoiding the considerable walking and time required in the conventional method of restarting strands from a leg of fiberizers back into a chopper. One of the pull rolls is free to move away from the other roll, but is biased against moving away to provide the grip needed to pull many strands at the same time.
