Abstract
A press force control apparatus for use in a apparatus for stacking sheets of paper that have been cut from a continuous roll of paper by inserting each successive sheet of paper beneath a previously stacked sheet of paper. The press force control apparatus includes a paper press for pressing a top surface of the sheets of paper, after the sheets of paper have been placed in a stacked position, wherein the paper press is translatable up and down with respect to a stack height of the sheets of paper. The press force control apparatus includes a press force switching facilities for dually functioning to contact the paper press to apply a press force to the paper press and thus hold the paper press in a downwardly translated position, wherein the paper press transfers the press force to the sheets of paper in the stacked position until the stack height of the sheets of paper in the stacked position reaches a predetermined value and to release the press force when the stack height of the sheets of paper exceeds the predetermined value. The press force switching facilities is provided with a mechanism for controlling the stack height at which the press force is released. The press force control apparatus assures that an appropriate press force is always applied to the sheets of paper so that the sheets of paper may be reliably successively stacked on the bottom of the stack.
