ABSTRACT:
A printing press having novel sheet transport mechanisms which facilitate precise operation at high speeds. In the preferred embodiment, the press includes a printing bed which pivots forward and downward on parallel links to remove sheets of stock from forwardly opening grippers. Also in the preferred embodiment, novel mechanisms for opening and closing the grippers are provided, including a mechanism for closing the grippers which is inoperable until the grippers are in the proper position to grip the leading edge of a sheet of stock.
