Abstract

A continuous motion cylindrical can decorator is provided with mandrels that receive undecorated cans and a deco chain that carries decorated cans through a curing oven. The mandrels are mounted along the periphery of a continuously rotating carrier. Chain speed is much slower than linear mandrel speed and spacing between pins on the chain is much less than spacing between mandrels. Interposed between the chain and the mandrel carrier is a continuously rotating transfer carrier having a plurality of suction holding devices thereto. As the holding devices move through a transfer region they are in single file and receive cans that are blown from the mandrels. In the transfer region mandrel linear speed is substantially greater than linear speed of the holding devices, and spacing between the latter is much less than spacing between mandrels As the loaded suction holding devices move downstream through a pickup region cans thereon are loaded on two rows of pins carried by the deco chain. Linear speed of the holding devices while moving through the transfer region exceeds chain speed, and in this region the holding devices are spaced apart by a distance that exceeds pin spacing. By the time the holding devices reach the pickup region they are arranged in two rows, are spaced apart and are moving at a speed such that they essentially track the moving pins while the latter are being loaded.
