ABSTRACT:
Apparatus and method for delaminating a composite sheet structure of the kind comprising a vertically frangible layer having a first surface adhesively bonded to a first sheet at a substantially uniform strength and an opposite surface abutting areas which are, respectively, adhesively bonded to a second sheet at strengths less or greater than the uniform strength and having a marginal portion or tab extending beyond the first sheet. The composite sheet structure is fed into the nip of upper and lower peel rollers and upon passage therethrough a strip sheet roller is rotated into position to bend and hold the laminate against the upper peel roller in a position to fracture the tab from the first sheet. On reversal of the feed direction and passage of the laminate back through the nip of the strip sheet and upper peel roller, the thicker "keeper sheet" of the flexed laminate breaks from the "throw-away" sheet containing the tab, at the preformed tab.
