An apparatus for adjustably positioning a form roll having a form roll axis against at least two different sized plate cylinders in a variable cutoff printing unit is provided. The apparatus includes a plate cylinder support for interchangeably supporting the at least two different sized plate cylinders, the plate cylinder support including a plate cylinder axis at least two different sized plate cylinder cams. The at least two different sized plate cylinder cams are interchangeably removably connectable to the plate cylinder support and include a smaller plate cylinder cam and a larger plate cylinder cam that are removably connectable to the plate cylinder support as alternatives of each other. The apparatus also includes a form roll hanger for supporting the form roll that is configured for contacting the smaller plate cylinder cam if the smaller plate cylinder cam is coupled to the plate cylinder support to set a smaller distance between the plate cylinder axis and the form roll axis. The form roll hanger is also configured for contacting the larger plate cylinder cam if the larger plate cylinder cam is coupled to the plate cylinder support to set a larger distance between the plate cylinder axis and the form roll axis. A method of adjustably positioning a form roll and a variable cutoff printing press are also provided.

A stitching head is provided for stitching books or printed products. The stitching head includes a supporter and a driver. The supporter has a corrugated supporter surface including first ridges and first grooves. The driver interacts with the supporter and has a channel and a corrugated driver surface which includes second ridges and second grooves. The first grooves and first ridges of the supporter mesh with the second ridges and second grooves of driver and the channel supports stitching material between the corrugated supporter surface and the corrugated driver surface. A method is also provided.

Spring loaded corrugated stitcher head and method of stitching

A stitching head is provided for stitching books or printed products. The stitching head includes a supporter and a driver. The supporter has a corrugated supporter surface including first ridges and first grooves. The driver interacts with the supporter and has a channel and a corrugated driver surface which includes second ridges and second grooves. The first grooves and first ridges of the supporter mesh with the second ridges and first grooves of driver and the channel supports stitching material between the corrugated supporter surface and the corrugated driver surface. A method is also provided.

A saddle stitching device including a saddle-back conveyor having a first printed product location and a second printed product location adjacent the first printed product location, a first stitcher adjacent the conveyor and driven by a first motor, and a second stitcher adjacent the conveyor and driven by a second motor.

Saddle stitcher with individual stitcher drives

The present invention relates to a method and apparatus for mounting a printing plate on a printing unit cylinder's surface, the printing unit cylinder having an open passage in a retaining area of the printing unit cylinder. Within the open passage a lock-up bar is slidably mounted. The lock-up bar includes an element for retaining at least one edge of the printing plate. A tucking device assigned to the printing unit cylinder has a tucker bar substantially covering the retaining area of the printing plate.

Method and apparatus for mounting a printing plate on a cylinder

The present invention is directed to an apparatus for mounting a printing plate on a printing unit cylinder, with the printing unit cylinder having an opening in a clamping area. A lock-up bar is slidably mounted in the opening of the printing unit cylinder, the lock-up bar having an element for retaining at least one edge of a printing plate. A tucking device substantially extends on the clamping area, the tucking device being provided with a protection element and with a plurality of tucking elements arranged over the clamping area and over the width of the printing unit cylinder.

Apparatus for mounting flexible plates in a printing unit

A rotatable plate cylinder (10) for supporting a printing plate (150) has an open passage (34) and a locking member (26) supported for movement in the passage (34). The locking member (26) is movable inward of the passage (34) to a closed position, and is movable outward of the passage (34) to an open position. The locking member (26) is subjected to a first centrifugal force which urges it to move outward from the closed position toward the open position when the plate cylinder (10) rotates. A balance member (28) is subjected to a second centrifugal force when the plate cylinder (10) rotates. Connecting pins (100) direct the second centrifugal force against the locking member (26) oppositely to the first centrifugal force.
