ABSTRACT:
A carriage, preferably carrying a knife for cutting a moving web for attachment of the cut web end to a web winding roll, is driven on a supporting rail along a linear path by means of a driving motor operating a toothed driving belt. The belt is detachably clamped to the carriage by a clamp fixed on the carriage and formed by a support plate having a belt supporting surface thereon and a pressure plate provided with teeth for mating engagement with the belt teeth mounted on the support plate in opposed relation to the support plate surface to define with the surface a slot for reception of the belt. The pressure plate is slidably supported for movement toward and away from the surface and is spring-biased to normally clamp the belt therebetween. Emergency stop means are effective if the carriage due to accident should exceed the normal end limits of its path to lift the pressure plate against the spring-bias away from the belt supporting surface and disengage the belt from the camp, allowing the carriage to be arrested by a shock absorber disposed adjacent each end of its path.
