INCREMENTAL VELOCITY CHANGING APPARATUS FOR TRANSPORTING PRINTED PRODUCTS IN A PRINTING PRESS FOLDER

摘要

A printing press folder includes a pair of cutting cylinders cutting a web to form signatures, a pair of transport and acceleration cylinders transporting the signatures. The transport cylinders define a first nip and the first nip and a 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 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.
