摘要： A folder for a printing press includes a cutting cylinder assembly having at least two knife and anvil cylinder sets positioned near the cutting region of a folder. The cutting cylinder assembly slides or actuates one of the knife and anvil cylinder sets into a cutting position for a desired cut length. The web passes between the knife and anvil cylinder set and is cut. When the cut length needs to be changed, the assembly is relocated to such a position that a second or further set of knife and anvil cylinders is aligned with the web.

摘要： A folding device is provided for folding n sheet comprises a jaw cylinder, a folding cylinder, a paper guide, and an actuator. The jaw cylinder has a jaw, and the folding cylinder has a hold down element and a folding blade. The folding blade is movable between an extended position and a retracted position. The folding blade is in the extended positron to transfer one or more sheets to the jaw cylinder during a fold off operation, and the folding blade is in the retracted position during a collect operation. The paper guide is positioned between the folding cylinder and the jaw cylinder. The paper guide includes a static guide element and a reciprocating guide element connected to the static guide element, the reciprocating guide element movable between a retracted position and an extended position. The actuator is connected to the reciprocating guide element; the actuator configured and arranged to place the reciprocating guide element into the extended position during the collect operation and into the retracted position during the fold-off operation.

摘要： 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.

摘要： 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.
