Thread-tensioning device on a warp creel

Abstract

A disc brake, formed from a lower disc and an upper disc, is fitted on a carrier which is fastened in position to a warp creel part by means of a single screw. The lower disc rests on a rotary cage which carries a gearwheel. This gearwheel meshes with a pinion on a drive shaft. This drive shaft runs at the point where the thread coming out of the warp creel is to be deflected towards a lapping machine and thereby forms, at the same time, a driven deflecting rod for deflecting the thread. Moreover, connected turnably to the drive shaft is a beveled part which forms, with its surface, part of a peripheral positioning of the upper disc and, at the same time, causes the upper disc to turn intermittently via the frictional connection with this upper disc. A pressure element, which is clamped releasably in a clamping piece, acts centrally on the upper disc. This clamping piece is connected via a pedestal to an adjusting sheet bar via which the pressure load of the upper disc can be varied simultaneously for several thread-tensioning devices.
