Abstract
Abstract This invention provides a sheet transfer mechanism for sheet fed rotary printing presses. A conventional transfer drum is provided with an angular lever mechanism for controlling the axial direction of the transfer drum. The angular lever mechanism is operated in conjunction with a control gear mechanism to provide separate operations on specific revolutions of the transfer drum. Gripper support spindles are mounted on the transfer drum with a control gear mechanism to effect a shift in a substantially circumferential direction to place the sheet being transferred in the desired position with respect to the transfer drum.
