DEVICE AND METHOD FOR HANDLING TRIM STRIP IN A WEB SLITTER

摘要

Trim strip in a web slitter having upper and lower rotary slitting means cooperating at a severance point for trimming a strip from the edge portion of a travelling web is engaged on a cylindrical rotary trim biasing and guiding surface associated with the lower slitting means. The trim strip is retained in wrapping engagement on the rotary surface by pressure differential and thereby positively transported away from the severance point into a chute. At a point spaced from the severance point the trim strip is stripped from the rotary surface for onward movement in the chute.
