Abstract

See full text

A printing press folder is provided. The printing press folder includes a pair of cutting cylinders cutting a web at a cutting location to form signatures, a pair of transport cylinders positively gripping and transporting the signatures and a pair of acceleration cylinders positively gripping and transporting the signatures. The transport cylinders define a first nip and the first nip and the cutting location are separated by a first distance that is slightly shorter than a length of each of the signatures. The acceleration cylinders define a second nip. The pair of transport cylinders receives and releases signatures at a first velocity and the pair of acceleration cylinders receives the signatures from the pair of transport cylinders and releases the signatures at a second velocity that is greater than the first velocity. The first nip and the second nip are separated by a distance that is slightly shorter than the length of each of the signatures, such that the transport cylinders release each of the signatures as the acceleration cylinders grip the respective signature and the transport and acceleration cylinders maintain positive control over the signatures during transport. A signature transport apparatus and a method for transporting printed products in a printing press folder are also provided.
