Abstract
In the pneumatic pressing of textile strands in a drafting frame the pressure in the pressure line is monitored by a pressure sensor and/or a flowmeter and used to control a value between the pressure source and that pressure line. According to the invention a disturbance signal is outputted when the pressure in the line drops below a threshold, the control signal for the valve exceeds a threshold, the displacement of the value member exceeds a certain level and the flow rate exceeds a value so as to indicate leakage beyond a tolerance level.
