Abstract
In a web winding apparatus for winding a web on a winding core, the winding core is rotated by a predetermined amount while an end portion of the web, which is held by a holding mechanism, is pressed against the winding core. Thereafter, the holding by the holding mechanism is released, and thereby the end portion of the web is attached to the winding core. Thereafter, the winding core is rotated, and the web is wound up on the winding core. A rotation speed of the winding core when the web is being pressed against the winding core is a higher speed than a rotation speed of the winding core at the time of attaching the web to the winding core. In this manner, the web is accurately wound on the winding core.
Claims18
A web winding method for winding a web on a winding core, the method comprising:
- rotating the winding core by a predetermined amount while pressing an end portion of the web, which is held by a holding mechanism, against the winding core, predetermined amount being set such that an attachment force between the winding core and the end portion of the web is generated by the winding core and the end portion of the web rubbing against each other, and thereafter, carrying out temporary attachment by attaching the end portion of the web to the winding core by releasing the holding by the holding mechanism;
- and
- after the temporary attachment by generation of the attachment force, starting rotation of the winding core to wind up the web on the winding core.
A web winding apparatus comprising:
- a rotation mechanism that rotates a winding core;
- a holding mechanism that is configured to be able to hold a web and configured to be able to move;
- and
- a controller that controls the rotation mechanism and the holding mechanism so that the winding core is rotated by a predetermined amount while an end portion of the web, which is held by the holding mechanism, is pressed against the winding core, the predetermined amount being set such that an attachment force between the winding core and the end portion of the web is generated by the winding core and the end portion of the web rubbing against each other, and thereafter, the winding core is rotated after the holding by the holding mechanism is released.
A producing method of a web obtained by winding the web on a winding core, the method comprising:
- rotating the winding core by a predetermined amount while holding an end portion of the web with a holding mechanism so that the end portion of the web is pressed against the winding core, the predetermined amount being set such that an attachment force between the winding core and the end portion of the web is generated by the winding core and the end portion of the web rubbing against each other, and thereafter, carrying out temporary attachment in which the end portion of the web is attached to the winding core by releasing the holding;
- and
- after the temporary attachment by generation of the attachment force, starting rotation of the winding core to wind up the web on the winding core.
