ABSTRACT:
An apparatus for forming a color image by transfer of at least one distinctively colored color image from a corresponding support therefor onto a single carrier support using a transfer cylinder for each color image for receiving on its periphery in a fixed location the image-carrying support and transport means carrying a register strip provided with register holes and attached to the leading end of the carrier support along a path tangential to the transfer cylinder periphery, the transfer cylinder including registering pins movable radially thereon between a retracted inoperative position and an operative projected position projecting outside the cylinder periphery for engagement with the register holes as the register strip arrives at the cylinder. After registration, the image-carrying support and carrier support are pressed together progressively along their length to transfer the image to the carrier support. The sequence is repeated at the transfer cylinder for each color image. The movement of the register pins is controlled timed relation to the transport of the register strip by control means, preferably a cam.
