Abstract

PURPOSE:To simplify the adjustment and control of winding force in accordance with winding-up conditions, by arranging a pressure regulating valve in a hydraulic circuit in a winder for a steel cold-rolling mill or the like, in which a wedge shape shaft is slid in an expansible and shrinkable winding barrel by means of a hydraulic rotary cylinder. CONSTITUTION:A control instruction signal alpha in accordance with winding conditions is delivered from a controller 28 to a pressure regulating valve 27 which is set, therefore, to meet with the winding conditions. In this stage hydraulic oil is regulated to a predetermined pressure by the regulating valve 27 when a directional control valve 2 is set at a position (a), and flows into a rotary cylinder 11 through a swivel joint header 9 so that a piston 12 pulls in a pyramid 14 for expanding segments 15 which are contracted when the directional control valve 2 is set to a position (b). With this arrangement, hydraulic control is undergone at will so that the adjustment and control of winding force in accordance with winding conditions may be suitably made and as well the life of a drum is prolonged.
