Processing machine for web material, in particular transverse format cutting machine for paper.

摘要

A pair of toothed wheels (34) which synchronise the motion of a pair of contra-rotating components (esp. cutting rolls) on a converting machine for web products (esp. a machine for cross-cutting paper into sheet lengths) have a mechanism for adjusting, in segments, and on at least one of the toothed wheels, the gap between the teeth of the two wheels. The rolls are of the type which carry sets of knives at their circumference.
