ABSTRACT:
Stripping apparatus to remove scrap around die cut blanks in a web comprises a roll pair through which the web is passed, one roll carrying spikes to impale the scrap pieces and the other roll carrying abutments to contact the scrap pieces on the opposite side to the spikes. According to the invention the abutments are retractable, so that effectively the scrap piece is pinched between the spike and abutment shortly before the nip of the rolls. FIG. 1 illustrates the preferred arrangement.
