Abstract
A folder apparatus is disclosed which has at least one lead-in tape mechanism having a left lead-in tape and left exit roller and a corresponding right lead-in tape and right exit roller, the fight and left lead-in tapes forming a signature passage for delivery of a stream of signatures. One of the exit rollers is spring-loaded in the direction of a fixed exit roller. The spring loading takes place with two springs acting opposite one another, the springs having different spring rates or modula. This dual spring action reduces pounding caused by the signatures as they pass through the lead-in tapes.
