Abstract: A paper thickness measuring device for use in a rotary paper feeding device having a rotating cylindrical drum. In a preferred embodiment of the present invention, a gripper is mounted on the cylindrical drum for gripping a sheet; and a target is mounted on the cylindrical drum and mechanically linked to the gripper such that a position of the target corresponds to displacement of the gripper by a gripped sheet. The target is arranged and configured for detection of the target position a predetermined time or at a downstream location after the gripper grips a sheet.

Abstract: A sheet material feeder includes a sheet material holder for holding a pile of sheet material, a rotating drum for transporting the sheet material from the pile, and an acceleration device receiving the sheet material from the rotating drum at a first speed and releasing the sheet material at a second speed greater than the first speed. Also disclosed is a sheet material feeder with a sheet material holder for holding a pile of sheet material; and a rotating drum for transporting the sheet material from the pile, the rotating drum including at least one sucker rotating with the drum for contacting the sheet material.

Abstract: A sheet material feeder includes a sheet material holder for holding a pile of sheet material; a sucker bar device having at least one sucker for contacting the sheet material, the sucker bar device having a pivot axis, and an actuator for pivoting the sucker bar device about the pivot axis and having a first position and a second position. When the actuator is in the first position, the sucker pivoting about the pivot axis from a first angle where the sucker contacts the sheet material by a predetermined angle so that the sucker removes the sheet material from the pile; and when the actuator is in the second position, the sucker pivoting about the pivot axis from a second angle where the sucker does not contact the sheet material.

Abstract: A rotary stitching device has a wire supply, a cutting device for cutting a wire section from the wire supply, and a rotating forming wheel having a forming wheel axis of rotation, the rotating forming wheel receiving the wire section. A rotating delivery wheel has a delivery wheel axis of rotation parallel to the forming wheel axis of rotation and an outer circumference, the delivery wheel having an opening in the outer circumference and having at least one stitching head, and the forming wheel placing the wire section in the opening to form a stitch. A printed product conveyor moves printed products in a direction perpendicular to the delivery wheel axis of rotation so that the printed products receive the stitch from the stitching head.
