"Apparatus in a system of stretching of a spinning machine, especially a structure of drawing machine, carding machine, brush or similar.For weighing of the roller stretching system, having at least one cylinder through pressure ".The present invention relates to a device in a system of stretching of a spinning machine, especially a structure of drawing machine, carding machine, brush or similar.For weighing of the rollers of the system of stretching.Having at least one cylinder through pressure with a piston that is actuated by means of pressure and is provided so as to be axially movable inside a cylinder housing and from which a stemThe piston extends the piston rod passing through at least a stopper cylinder that forms the boundary of the housing of the cylinder.Where there is a disposition of the sensor to determine the position of the piston with the piston rod.In order to improve the device still further, to determine the position of the piston with the piston rod.An optical distance sensor explores the distances with respect to a counter element and the distance sensor is connected to an evaluation device of electric.
