Abstract

This tape winding arm is part of a winding device for film strips, tape or other similar medium, where the medium is wound up onto rolls. The medium passes over the end of the winding arm along guiding and deflecting elements on a cushion of compressed air, which is supplied through a hollow in the arm, and past a rotating pinch roller. This pinch roller is also part of the winding arm, and the winding arm is made of lightweight metal and pivots, so that its pinch roller rests on the tape roll, helping to ensure even winding through constant contact with the roll. The winding arm consists of two parts screwed together at the pivot point; this allows easy disassembly and removal from the pivot spindle.
