A printing press is provided. The printing press includes a print unit printing a stream of printed products having a first pitch, a pitch changing device and a controller. The pitch changing device includes an upper roller mounted on an upper axle, a lower roller mounted on a lower axle, the upper and lower rollers forming a roller nip and at least one motor driving the upper and lower rollers in opposite directions. The roller nip receives the stream of printed products. The controller is connected to the at least one motor and is configured to decrease an initial velocity of the roller nip to a final velocity using an electronic cam velocity profile and to increase the final velocity of the nip to the initial velocity after releasing the printed products over a longer period of a cycle of the electronic cam velocity profile than decreasing the initial velocity to the final velocity. A method is also provided.

Conveyor and method for changing the pitch of printed products

A double cut folder is provided for a printing press. The folder has a first cutting cylinder pair including a first knife cylinder and a first anvil cylinder for perforating a web, and a second cutting cylinder pair including a second knife cylinder and a second anvil cylinder for cutting the web into signatures. Each cutting cylinder pair includes a plurality of knife mounting locations and a plurality of cutting rubber locations. Each knife mounting location is configured to hold a knife box. A first subset of the plurality of knife mounting locations each have a knife box secured therein, and a second subset of the plurality of knife mounting locations do not have a knife box secured therein.

Double cut folder with variable knife mounting locations on cutting cylinders

An apparatus for driving a pair of nip rollers at a rotational velocity that varies within each revolution is provided. A first nip roller and a second nip roller form a nip therebetween for moving a sheet or signature. A drive configured and arranged to drive a drive shaft at a constant rotational speed. A pair of variable rotational speed couplings each have an input coupled to the drive, and an output connected to a respective one of the first and second nip rollers. Each coupling rotates its respective nip roller at a rotational speed that varies within each revolution.

Variable rotational speed coupling for a pitch changing or slow down device

A nip roller is provided that includes a shaft, a first nip disk portion, a second nip disk portion and an attachment section for removably securing the first nip disk portion and the second nip disk portion to the shaft.

Nip rollers with removable disks

A ribbon transport apparatus for a printing press is provided. The ribbon transport apparatus includes a vacuum conveyor belt transporting a ribbon and a manifold supporting the vacuum conveyor belt. The vacuum conveyor belt and the manifold are arranged to draw the ribbon towards the vacuum conveyor belt via a suction. A method of transporting a ribbon in a printing press is also provided.
