Roller arrangement for a booklet maker

摘要

A roller arrangement for booklet makers comprises at least a first ( 1 ) and a second ( 2 ) pair of rotatably driven rollers, between which booklets ( 4 ) are intended to pass successively for folding. The first pair of rollers comprises two rollers ( 1 ) that are arranged such that they can move towards and away from each other and having a spring loading towards each other, while the second pair of rollers ( 2 ) comprises two rollers with a mutual separation that can be adjusted. Mechanical means ( 3 ) are arranged to, following the insertion of a booklet between the rollers of the first pair of rollers, automatically adjust the mutual separation of the rollers of the second pair of rollers depending on the distance between the rollers of the first pair of rollers.
