The inner peripheral surface of the core member 22a is supported at two points on both sides of the bent portion 15a of each leaf spring 15, as shown in FIG.
The core material 22a is elastically supported by the leaf spring 15.
Since the rotational resistance between the leaf spring 15 and the inner peripheral surface of the core 22a is set to be larger than the rotational resistance between the fixed cylinder 5 and the rotary cylinder 6, the take-up roll 22 and the rotary cylinder 6 are separated from each other. While rotating integrally, the rotary cylinder 6 can rotate with respect to the fixed cylinder 5. The rotational resistance between the fixed cylinder 5 and the rotary cylinder 6 is the frictional resistance between the plastic rotary cylinder 6 and the resin sheet 10 and the frictional resistance between the resin sheet 10 and the metal fixed cylinder 5. It is determined according to the elastic force of the compression coil spring 11. The rotation resistance is adjusted mainly by moving the ring plate 12 to change the elastic force of the compression coil spring 11.

て支障を来すことを防止できる。Now, in the state where the winding roll 22 is supported by the supporting device configured as described above, as shown in FIG. The fitting projection wall 14 of the rotary cylinder 6 of the first support member 3 is loosely fitted to the inner peripheral surface on one end side of the core member 22a of the winding roll 22 fixed to the end side by the bolt 23 and inserted into the mounting shaft 1. At the same time, the leaf springs 15 of the rotary cylinder 6 are pressed against the inner peripheral surface of the core member 22a so that the take-up roll 22 and the rotary cylinder 6 can rotate integrally. On the other hand, the fixed cylinder 16 of the second support tool 4 is attached to the mounting shaft 1.
Is fixed to the tip end side of the second support tool 4 by a bolt 24, and each fitting protruding wall 21 of the support cylinder 17 of the second support tool 4 is loosely fitted to the inner peripheral surface of the other end of the core material 22a of the winding roll 22. With this attached state,
When the wrapping film of the winding roll 22 is pulled out by driving the film conveying device of the wrapping machine, the winding roll 22 receives a certain rotation resistance with respect to the fixed cylinder 5 of the first support tool 3 and the rotation cylinder 6 is formed. At the same time, they rotate integrally with each other, and rotate on the outside of the support cylinder 17 of the second support tool 4 with a slight space therebetween. Since the core material 22a of the winding roll 22 is elastically supported by the leaf spring 15 as described above, the leading end side of the winding roll 22a is irregular due to a change in pullout resistance when pulling out the packaging film and other causes. Even when the film is idled, the support cylinder 17 of the second support tool 4 blocks this, so that there is substantially no problem in drawing out the film. Further, as described above, since the pressure contact force between the fixed cylinder 5 and the rotary cylinder 6 can be adjusted, it is possible to prevent the rotary cylinder 6 from idling due to inertial rotation and pulling out an extra packaging film to cause a trouble. .

Therefore, the entire winding roll 22 can be removed from the mounting shaft 1.

When pushed in, the inner peripheral surface of the core member 22a slides on the second support tool 4 and one end thereof is fitted into each leaf spring 15 and each fitting projecting wall 14 of the first support tool 3. Therefore, the entire winding roll 22 can be supported by both the support members 3 and 4.
