ABSTRACT:
A folder collect cylinder comprises at least five gripper mechanisms and an equal number of tucking mechanisms controlled by non-rotating cams that are selectively masked by masking cams that rotate about an axis coincident with the cylinder axis. The masking cams are driven from the main collect cylinder drive through a transmission that can be adjusted to change the speed ratio of the masking cams to the collect cylinder and the phase of the masking cams to the gripper mechanisms to provide non-collect, two-collect, three-collect and partial-collect without ever masking the taking surface of the non-rotating gripper cam during a taking phase of any gripper mechanism.
