ABSTRACT:
Methods and apparatuses for tearing computer printer paper margin pieces from the main part of the paper sheet. The apparatuses include base and operative members having opposing jaws which are controllably movable between open and grasping positions. The jaws are formed with inwardly converging lips which guide the paper stacks into place. A backstop is provided to align the paper with respect to the jaws. An end stop can also be provided. Biasing is provided to open the jaws and a separation limiting structure is used to automatically stop the jaw opening at a predetermined limit. Arched jaw faces are shown for improved gripping of the sheets.
