ABSTRACT:
A winding apparatus for web material with severing device comprising a pair of power driven endless cutter chains wherein the tension of the cutter chains is adjusted during operation of the winding apparatus and thereby avoids the need for periodic manual adjustment and the problems attendant thereto. The device for adjusting the tension comprises a force applying fluid cylinder to move one of the sprockets carrying each chain to a position which increases the tension. A cooperating latch device serves to secure the sprocket in any adjusted position.
