Abstract: A conveyor for moving an elongated workpiece around a loop path without turning it end for end. A track is provided in the form of a loop with at least one main run, which may be straight, and loop ends that join the main run at spaced positions. Auxiliary end tracks are offset from the respective loop ends and join the main run with the loop ends, at junctions. A carrier having a pair of track followers engages the track and is propelled by an endless drive. A switch is operable to connect the main run to the respective loop end or alternatively to the respective auxiliary end. The switch is controlled by a switch operator that is responsive to the position of a carrier to operate the switch after a first follower on a carrier has passed the switch, but before the second follower has passed the switch, so that the carrier then moves laterally to the main run with one follower engaging the loop end and the other follower moving on the auxiliary end.

Abstract: Method for dry printing from a foil onto a workpiece having a contoured (inclined) surface. As the workpiece is advanced linearly beneath a foil applicator roll, an inclined surface on the workpiece will shift the roll in a vertical direction relative to a carriage, from which the roll is biased downwardly. Such roll movement is sensed and causes a force to be applied to the carriage, to move the carriage in a vertical direction so that it "follows" the roll. The carriage movement is limited to an amount sufficient that a pre-established downward biasing force on the roll will be restored, so that the roll pressure on the foil is maintained within an effective printing range. Further a driving force is applied to the roll and foil that tends to move them faster than the rate at which the workpiece is being advanced.
