Abstract
A transfer-printing process and apparatus for transfer-printing from a master card onto a work piece. The process starts by manual insertion of the master card into a gap provided between press rollers. By the insertion of the master card, the work piece is fed into a work piece path and the surface thereof is wetted during its movement along the path. The work piece thus fed and the master card sustained between the gap are registered with each other as desired and pressed for transfer-printing by the rotation of the press rollers. The work piece and the master card are then delivered to the insertion inlet of the master card.
Claims4
A transfer-printing apparatus including:
- workpiece advancing rollers which remove workpieces one by one from a workpiece hopper wherein workpieces are stacked and advance each workpiece to a printing station along a path, means for moistening each workpiece with solvent during the path of advancement of the workpieces;
- a transfer-printing mechanism having two cooperating rotatable press rollers with rotation axles parallel to those of the workpiece advancing rollers, a first press roller of the two press rollers having a surface consisting of a flat portion and a cylindrical pressing portion;
- the flat portion serving to create a gap between said first and second press rollers when the flat portion is located adjacent the second roller for inserting therethrough a master card with printed materials thereon, the cylindrical pressing portion cooperating with said second press roller to press together the workpiece and the master card to transfer-print the printed materials and to remove the master card together with the workpiece in a direction opposite to the direction of insertion of the master card;
- a master card postiion detector which generates a signal when the leading edge of a master card is manually inserted through the gap to a predetermined position;
- a workpiece position detector provided along the path for generating a signal when the leading edge of the workpiece reaches a predetermined point;
- a driving mechanism for driving the workpiece advancing rollers and for driving the transfer-printing mechanism for one rotation to transfer-print and to orient the first press roller flat portion adjacent the second roller to recreate said gap between the flat portion and the second press roller after completion of the transfer-printing;
- and a driving mechanism control circuit for controlling the driving mechanism so that the workpiece advancing rollers move the workpiece in accordance with the signal from the master card position detector and so that the transfer-printing mechanism begins operation after a predetermined time interval after the signal is generated from the workpiece position detector.
