ABSTRACT:
A means and method for handling trim strip slit from the margin of a travelling web, comprising rotary means by which biasing forces is applied to the strip away from the slitter into the chute. Within the chute relatively low velocity means advance the trim strip in a foldably bunched condition toward the bottom of the chute where the bunched trim strip is then transported away from the chute. Low velocity air, as well as rotary members are provided in the chute for effecting the foldable bunching and advancing of the trim strip. Either or both of low velocity air and mechanical conveying apparatus may be provided for transporting the trim strip away from the bottom of the chute.
