Document Type and Number:
WIPO Patent Application WO/2014/083632
Kind Code:
A1
Abstract:
A take-up device (2) is provided with: a hydraulic device (9); a pressure detecting device (11); a pressure calculation means (18); and a control means (22). The hydraulic device (9) is a device for expanding and contracting a mandrel (7). The pressure detecting device (11) detects the pressure of hydraulic fluid in the hydraulic device (9). The pressure calculation means (18) calculates the tightening pressure operating on the mandrel (7) on the basis of the pressure detected by the pressure detecting device (11). The control means (22) controls the hydraulic device (9). In addition, the control means (22) carries out positioning control until the number of strip (3) windings reaches w3. The control means (22) carries out constant pressure control after the number of strip (3) windings reaches w3.
