Abstract
A thermally exposed laminate is passed between the nip of a pair of peel and pressure rollers toward a pair of tab and deflector rollers which are movable through an arcuate path, such that, the tab roller initiates separation of the disposable sheet from the retained sheet and pulls the disposable sheet between the driven tab and peel rollers, while the retained sheet is contacted by the deflector roller for bending of the sheet around the pressure roller. The disposable and retained sheets are traversed through divergent paths, respectively to waste and to the next processing stage.
