Abstract

PURPOSE:To reduce abrasion and as well to enhance the perfomance of a segmented winding shaft which is adjusted by fluid pressure, with winding torque transmitted to a winding core that is fitted onto the shaft, by using the end faces of lug plates as means for frictionally driving a winding core holding collar. CONSTITUTION:Internal pressure in a fluid pipe 2 is gradually increased by rotatingly driving frictional lugs 4 in through-holes 3 together with a hollow shaft 1 upon rotating, so that friction between the frictional rugs 4 and a frictional ring 9 on the side of a winding core holding collar 6 is also gradually increased. This collar 6 is fixed to a winding core C by spherical members 8 serving as wedges, and therefore frictional force between the frictional lugs 4 and the frictional ring 9 rotationally drives the winding core C. Accordingly, widing torque by the winding core C is proportional to the number of the collars 6 for holding the winding core C and the internal pressure of the fluid pipe 2, thereby the control of gradual reduction of tension is precisely carried out in accorandace with the conditions of sheet winding under the control of fluid pressure.
