Abstract
A roller cage having at least one needle roller on one side and larger rollers having axes parallel thereto on the other side, a print transfer plate having a reciprocal sliding drive means extending through the roller cage with opposite sides in contact with the respectively oppositely disposed rollers, the larger rollers adapted to roll on a plate disposed parallel to a printing form, which plate has lateral recessed grooves into which the rollers roll prior to and after the printing operation to increase the distance between the needle roller and the printing form for inserting sheets to be printed and removing printed sheets which are pressed against a dye support and printing form by the needle roller during the printing process, and an inclined plane and stop mechanism functioning to raise and lower said plate as it moves back and forth under the influence of the reciprocating print transfer plate during the printing operation.
