ためになされたものである。The prior art has the following drawbacks. Burrs are formed at the peripheral edges of the strip-shaped long material (15) of each line slit in the slit process of the strip-shaped long material (15). When the strip-shaped long material (15) in which each burr is generated is simultaneously wound on the same winding shaft,
Since the winding diameter is different for each strip due to the difference in the thickness of the burr generated by each strip, the tension of each strip cannot be kept constant. For this reason, the coil of the strip-shaped long material (15) wound on each strip is loosened. For this reason, after the winding, the coil of the strip-shaped long material (15) is removed from the winding shaft, and then winding is tightened by using a jig or the like for each line. In the winding step, scratches and the like were generated and the quality of the strip-shaped long material (15) was remarkably impaired, and the winding operation was very heavy work, which caused the operator pain. Further, there is a winding device that employs a looping winding method as a method for preventing the loosening of the strip-shaped long material (15) by another conventional technique, but this method also has the following drawbacks. In this winding system, a winding drum corresponding to the number of winding strips is fixed to the same winding shaft with a key or the like to prevent the slippage of the winding shaft of the strip-shaped long material (15). Immediately before, the strip long material (15) of each strip is pressed down with a strong pressure by a pad or the like.
When a strong driving force is applied to the take-up shaft, each strip can be wound in a tightly wound state due to the ironing phenomenon that resists the braking force of the immediately preceding pad, but a strip with a small winding diameter due to the difference in burr thickness Since the winding length is short, it cannot be wound to the same length as other strips, and it hangs down in front of the putt. Long strip material (15)
Since the amount of drooping gradually increases in proportion to the length of winding, the burrow was accommodated by digging a deep hole as deep as ten meters or so underground. It takes a great deal of money to dig this deep hole, which increases the installation cost of the slitter line, increases the installation area, reduces workability, and increases the risk of workers. Further, there is a drawback that abrasion is generated by ironing due to pressing of the pad, which causes a deterioration in quality. The present invention has been made to eliminate these drawbacks.

る。Operation (see FIGS. 3 and 5) A liquid or gas under pressure is applied to the hollow portion (2) of the hollow winding shaft (1) which is open in one direction and the tip of the hollow portion (2) does not penetrate. Pump in and apply pressure. When pressure is applied, the piston (5) is pushed up and pushes the winding ring (8). Then, a strong frictional force is generated between the piston (5) and the winding ring (8), and the winding ring (8) brakes. Since the winding tension can be set by increasing or decreasing the pressure of the liquid or gas fed into the hollow portion (2) with a pressure adjusting valve (11) prepared separately, the frictional force can be increased or decreased. An appropriate winding tension can be set by arbitrarily setting the pressure of liquid, liquid, or gas. Long strip material (15)
When the winding tension is properly set by the pressure adjusting valve (11) and the hollow winding shaft (1) is driven, the rotation of the hollow winding shaft (1) causes the piston (5) to rotate. And the winding ring (8) is rotated by being transmitted to the winding ring (8) by the braking force due to the frictional force of the winding ring (8). The strip-shaped long material (15) is fixed and wound on the winding ring (8) for winding. If the winding tension of a strip having a large winding diameter becomes strong due to the mismatch of the cutting burr thickness of the individual strips due to the slits of the strip-shaped long material (15), the braking force between the piston (5) and the winding ring (8) is resisted. Then, the winding ring (8) slips to stop the winding, and the other windings having a weak winding tension continue to rotate due to the braking force of the winding ring (8). Then, when the tension of the strip at which the winding is stopped becomes weak, the winding ring (8), which has been slipping, is again rotated by the braking force and winding is performed. The above operation is repeated. (See FIGS. 4 and 6) For winding a strip-shaped long material (15) that requires particularly weak winding tension, a liquid or gas fed into the hollow portion (2) of the hollow winding shaft (1). The pressure of is reduced to push the piston (5) into the cylinder hole (4) with the pressure of the spring (7),
The friction force between the piston (5) and the take-up ring (8) is released, and the hollow take-up shaft (1) is rotated by a weak braking force due to the pressing force of only the spring (7) and the take-up ring (8). Can be transmitted to the winding ring (8) to wind the strip-shaped long material (15) which requires particularly weak tension. The pressing force of the spring (7) is adjusted by the cushioning action of the piston (5) by increasing or decreasing the pressure of the liquid or gas in the hollow portion (2).
