Abstract
An assembly of filament-drawing rollers, used for stretching rovings or fiber bundles in a spinning machine, is divided into a plurality of stages each including an elongate driven roller and a set of coacting counterrollers, the driven rollers being interconnected at both ends by respective gear trains for rotation at predetermined relative speeds by a motor driving one of these gear trains. In order to prevent any overstressing of the mechanism if nonmatching gears are inadvertently inserted into the two gear trains, a torque limiter in the form of a shearing bolt or a friction clutch is interposed between at least one driven roller and an associated driving gear. Advantageously, the torque limiter is provided with a device generating an alarm signal upon relative rotation, due to overload, of its input and output shafts respectively joined to the driving gear and the driven roller.
