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
First Claim
1. An apparatus on a drafting system of a spinning machine for weighting a drafting system roller, comprising:
- a cylinder;
a piston axially movable within the cylinder;
a piston rod extending from the piston for applying weighting to the roller;
a sensor; and
an evaluation device;
wherein the sensor is an optical sensor arranged to determine a distance between the sensor and a counter-element and the sensor is connected to the evaluation device for determining the position of the piston and piston rod.

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.
