When manufacturing aluminum foil, etc., a large diameter roll is used as the base material, and a specified length is wound onto a cylindrical core made of cardboard or the like. Therefore, when attaching the core to the winding device,
Fit the core onto the core mounting shaft, attach a collar member having an end surface with a larger diameter than the core to both ends of the core mounting shaft to support each end of the core, and attach the collar member to the core mounting shaft with screws or pins. By fixing the core to the core mounting shaft, the core and the core mounting shaft are integrated. Then, the core mounting shaft with the core fitted thereon is set in the winding device, and the device is driven to wind the base material of a specified length around the core into a roll shape, and then the core mounting shaft is removed from the device. Loosen the screws and pins to remove the collar member from the core mounting shaft, remove the rolled roll from the core mounting shaft, fit a new core onto the core mounting shaft, and use the collar member to attach each core again. The end is supported and fixed to the core mounting shaft with screws or pins. Then, the core mounting shaft to which this core is fixed is again set in the winding device.
〈考案が解決しようとする問題点〉

に手数がかかり、作業能率が悪い。<Problems to be solved by the invention> Therefore, in order to attach the core to the core attachment shaft in a conventional winding device, the collar member must be fixed to the core attachment shaft each time with screws or pins. Furthermore, when removing the core after winding, the core must be removed by loosening the screws and pins and removing the collar member before the core can be attached or removed. Therefore, attaching and detaching the core takes time and labor, resulting in poor work efficiency.

It will not be deformed or damaged. Furthermore, the free rotation prevention mechanism consisting of the concave-convex fitting means allows the receiving shaft part and the cap part to rotate together without any slippage, so that the core etc. are not twisted during winding. Therefore, there is no need to cut off the end of the roll after winding and discard the deformed and damaged portion, and the entire length of the roll can be effectively used, resulting in no waste, which is highly economical. In addition, products such as toilet paper rolled up using the core-mounted shaft of the present invention have high commercial value because their edges are not damaged.
