And a pneumatic pressing mechanism 6 for pressing the lug 5 against the inner peripheral surface of the core on the shaft 4 by the action of compressed air. The illustrated pneumatic pressing mechanism 6 includes:
A tube that expands in accordance with the pressure of the supplied compressed air. When the core is fixed, compressed air is supplied to the tube 6 from the plug 7 with a check valve to expand the tube as shown by a chain line. The lug 5 is pushed up to project from the outer peripheral surface of the shaft body 4 through a hole provided in the shaft body 4, and the core is firmly held so as to rotate together with the shaft body 4. When releasing the holding of the core, the function of the check valve of the stopper 7 is released to release the air in the tube. Since the compressed air in the tube 6 does not escape during the winding of the sheet, the pressing force of the lug 5 on the inner peripheral surface of the winding core is kept constant.

The sheet roll R wound around C is deformed into a bowl shape, and is likely to be defective. Therefore, in the related art, the outer peripheral surface of the sheet roll is supported from below by a supporting roller during winding to prevent the air shaft from bending.

When the control becomes complicated, the size of the apparatus increases and the workability deteriorates. Therefore, the present invention provides a plurality of narrow sheets divided by a slitter,
It is an object of the present invention to wind up the winding core so as not to be defective without providing a supporting roller for preventing the air shaft from bending around each winding core held in an adjacent state by the air shaft.

空気の圧力を大きくすることを特徴とする。SUMMARY OF THE INVENTION According to the present invention, the pressure of compressed air supplied to a pneumatic pressing mechanism for pressing a lug against the inner peripheral surface of a core of an air shaft at the beginning of winding is reduced, thereby reducing the pressure on the core. When the sheet winding amount increases, the pressure of the compressed air supplied to the pressing mechanism is increased.

確実に固定することができる。By supplying compressed air with low pressure to the pneumatic pressing mechanism of the air shaft at the beginning of winding, even if the core is easily deformed like a thin paper tube or a plastic tube, When the core is penetrated by the shaft and the inner peripheral surface is pressed by the lugs, the pressing force by the lugs on the inner peripheral surface is reduced, so that the core is deformed into a polygonal shape, for example. Poor quality can be prevented. In addition, since the winding torque at the start of winding is small, even if the pressing force of the lug is reduced, the winding core can be securely fixed to the shaft so as not to run idle.

良品になるのを防ぐ。When the winding amount of the sheet on the core increases to a certain extent, the core is reinforced by the sheets wound on the core in a number of layers. However, the core is not substantially deformed. Therefore, as the sheet winding amount increases, the pressure of the compressed air supplied to the pneumatic pressing mechanism that presses the lug against the inner peripheral surface of the core increases, thereby increasing the pressing force of the lug to the inner periphery of the core. This prevents the core from being shifted in the longitudinal direction of the shaft and leaving a gap between the adjacent cores, and prevents the sheet roll from deforming into a bowl shape and becoming defective.
