Abstract
An apparatus on a drafting system of a spinning machine, especially a draw frame, carding machine, combing machine or the like, for weighting the drafting system rollers, has at least one pressure fluid cylinder with a piston which is acted upon by pressure fluid and is arranged so as to be axially movable inside a cylinder housing and from which a piston rod extends. The piston rod passes through at least one cylinder cover that forms the end boundary of the cylinder housing. For determining the position of the piston with the piston rod, an optical distance sensor scans the distances with respect to a counter-element and the distance sensor is connected to an evaluation device.
