Handling device for strip or sheet of paper - incorporates cross-beams and longitudinal support for tool-carrying positioner guided across path of incoming material

摘要

The material is conveyed along a path (25) associated with two or more movable tools and adjustment devices positioned automatically by a drive (37). A positioner (34) is driven along a threaded spindle (36) across the path (25) between guide bars (33). The tools are selectively coupled and uncoupled by catches and a pneumatic cylinder. They are spaced by thrust rods at predetermined distances away from the positioner (34), with different lengths such that all catches and grooves are correctly positioned at rest. The actual position of the tool is detected by a sensor. ADVANTAGE - Resetting of machinery for cutting or stacking different formats is facilitated and accelerated.
