Apparatus for slowing down signatures sent to a quarter fold of a folder for a printing machine

摘要

An apparatus and method for slowing down signatures sent to a quarter fold of a folder for a printing machine are disclosed. Signatures are transported between a first set of fast belts including upper belts and lower belts. The signatures are then received at their leading edge by an assembly of upper and lower partial pulleys mounted to a frame which changes the speed of the signatures to a slow speed. The signatures are then received at their leading edge by a second set of slow belts including upper belts and lower belts.
