Abstract
The disclosure relates to a tucker cylinder which cooperates with a folding cylinder to fold a sheet. The tucker cylinder is rotatable about a first axis and has a cylindrical outside surface and a circular end face. A tucker blade is connected to a carrier which is rotatable about a second axis within the tucker cylinder and parallel to and spaced from the first axis about which the tucker cylinder rotates. The carrier has a slot extending radially of the second axis, and a member fixed to the end face of the tucker cylinder slidably engaging the slot for transmitting rotary motion of the tucker cylinder to said carrier. An arcuate opening is formed in the end face through which the member extends. The arcuate opening is coaxial with the first axis of rotation of the tucker cylinder, and the member is adjustably positioned in the opening to adjust the timing of the motion of the tucker carrier.
