Is a perforated arm and is rotatably mounted on the bracket 6 via a bearing 7. The pins 8 projecting from the arm 5 and the pins 13 projecting from the bracket 6 are connected by a spring 14 attached thereto. still,
The spring 5 and the like are not shown on the arm 5 shown as a cross-sectional view on the left side of the roller 3 in FIG. 2, but the spring 14 is provided via the spring 14 like the arm 5 shown on the right side of the roller 3. The arm 5 and the bracket 6 are connected together. The springs 14 may not be installed on both sides of the arm 5 and may be provided on only one side. The shaft 4 on which the roller 3 is mounted is fixed by the bolt 9 while being engaged with the recesses 5a of the pair of arms 5. Reference numeral 10 denotes a retainer that prevents the arm 5 from being detached from the bracket 6, and is attached to the bracket 6 with screw bodies 11 and 12 and a pin 13. The above-mentioned bracket 6 is mounted on the shaft body 15, and the key 16 attached to the bracket 6 is moved in a state of being engaged with the groove 15a formed along the longitudinal direction of the shaft center of the shaft body 15, and the butterfly screw It is fixed to the shaft body 15 by 17. The shaft 15 is mounted on the machine base 2 and the bearing 1
It is rotatably mounted via 8 and 19, and a lever 20 is attached to the end. Reference numeral 21 denotes a fluid cylinder rotatably mounted on the machine base 2 via a fixture 22, and a piston rod is connected to the lever 20 via a joint 23. A compressed air supply pipe 24 having a pressure control valve for supplying compressed air, a supply path switching valve, etc. is connected to the fluid cylinder 21. Then, when the piston rod is projected by supplying compressed air, the bracket 6 is rotated counterclockwise together with the shaft body 15 via the lever 20, and the pin 13 protruding from the bracket 6 is formed on the arm 5. The arm 5 is pressed against the recessed portion 5a formed therein and is rotated in a direction away from the tube 30. On the other hand, when the piston rod is retracted, the shaft 15 is pushed through the lever 20.
At the same time, the bracket 6 is rotated in the clockwise direction so that the screw body 12 projecting from the bracket 6 comes into contact with the concave portion 5b formed in the arm 5 so that the arm 5 is pressed and rotated in the direction approaching the tube 30. .

Instead of the fluid cylinder described above, it is also possible to use a device that rotates normally or reversely with a pressure fluid, or an electric motor or the like.

When winding a sheet-like material with the above-mentioned surface pressure applying device,
First, the tube 30 is inserted into the sheet-like material winding position of the chuck 1 and tightened. Next, in order to mount the roller 3 corresponding to the width dimension of the sheet-like material 31, the butterfly screw 17 is loosened, and the arm 5 together with the bracket 6 is moved in the longitudinal direction of the axial center along the groove 15a formed in the shaft body 15. Then, the butterfly screw 17 is tightened at a predetermined position to fix the bracket 6 to the shaft body 15. Then, when each arm 5 is set at a predetermined position, the shaft 4 having the roller 3 corresponding to the width dimension of the sheet-like material 31 is engaged with the recess 5a formed at the end of the arm 5 and the bolt 9 is tightened. To fix. If a plurality of sheet-like materials 31 are used as one chuck 1 like a slitter winder.
In the case of simultaneously winding the tube 30 tightly attached to each other, the pair of arms 5 and the surface pressure imparting device such as the roller 3 are installed corresponding to each sheet-like material 31.

When each roller 3 is installed at a predetermined pressing position by the above-mentioned operation, the pressure control valve of the compressed air supply pipe 24 is operated to bring the roller 3 into contact with the tube 30 with a preset pressing force. The pressure of the compressed air supplied to the cylinder 21 is adjusted. Then, the supply path of the compressed air supply pipe 24 is switched to the first
Withdraw the piston rod as shown
The bracket 6 is rotated clockwise together with the shaft body 15 via. Then, the arm 5 is pulled and rotated by the spring 14, and the roller 3 is brought into contact with the peripheral surface of the tube 30. When these preparations are completed, the winding machine is started to wind the sheet-like material 31.

In the above-described winding operation, when a plurality of sheet-shaped materials are wound at the same time, even if all the sheet-shaped materials 31 are wound under the same tension and the same surface pressure condition, the center of the winding machine in the width direction. The sheet-like material wound in the end portion and the sheet-like material wound in the end portion are different in the amount of entrainment of the accompanying airflow associated with the winding, resulting in a difference in the winding diameter. However, since each arm 5 is connected to the bracket 6 integrated with the shaft body 15 via the spring 14, each roller 3 is rotated together with the arm 5, and even if there is a difference in the winding diameter, it does not contact the peripheral surface. There is no gap in the roller 3, and the receiving is performed in a state where the roller 3 is in contact with the outer peripheral surface of the sheet-like material with substantially the same surface pressure.

The present invention can be carried out as described above, but the shaft 15 on which the arm 5 is mounted is not rotated by the fluid cylinder 21, but the shaft 15 is movably mounted on the machine base 2 via a bracket or the like. Alternatively, the fluid cylinder or the driving device such as an electric motor and a rack or a pinion may be moved so as to move toward and away from the chuck 1.

(Effects of the Invention) The present invention includes a shaft body rotatably supported by a machine base as described above and rotated by a drive device, and at least a pair of shaft bodies slidably mounted in the shaft center longitudinal direction.
