ABSTRACT:
A friction brake used in association with a supply roll in a device advancing sheet material from a supply roll onto a take-up roll. The brake comprises a shaft supported by a plate and having a head at one end and a threaded portion at the other. A journalling part, a reverse bias arm, and a friction washer interposed between the arm and journalling part are each rotatably supported on the shaft and are biased together by axial adjustment means positioned adjacent the shaft threaded end portion. The axial adjustment means cooperates against one side of the plate to clamp the rotatably supported members against the plate other side. The reverse bias arm creates on the supply roll a drag when sheet material is pulled and subsequently delivers to the supply roll a reverse bias force after the pulling of material stops.
