Abstract
The three-side trimmer comprises three compact cutting units of a nearly identical design, which have a flow of forces that is closed in itself and separate drives. Full-area cutting tables and pressing plates and telescopic cutting tables and pressing plates in the head-and-foot station ensure optimal quality of cut while avoiding the use of replaceable parts for format change. Due to elastic design and a slightly oblique positioning of the pressing plates, air inclusions are prevented from occurring during the pressing. A most lightweight design possible with weak dynamic forces to achieve good quality of cut are provided while avoiding the use of replaceable parts for format change.
