Claims

[Scope of utility model registration request]

A bed roll 1 is provided for winding the continuous web W unwound from the raw roll P, and the continuous web W is sequentially cut into regular length webs X, X, etc. each having a predetermined length L on the outer peripheral surface 1a of the bed roll 1. A web cutting device 5 for cutting the web at a peripheral speed that is located on the side in the web traveling direction from the web cutting position on the bed roll outer peripheral surface 1a, is brought close to the bed roll outer peripheral surface 1a, and is slower than the peripheral speed of the bed roll outer peripheral surface 1a. Moreover, the retard roll 2 is rotated in the opposite direction to the rotation direction of the bed roll, and each fixed length web X, which is located close to the outer peripheral surface 2a of the retard roll 2,
A winding roll 4 constituting a part of a web winding device 3 that functions to wind up X into a roll shape is provided, and furthermore, the bed roll 1 is provided with a winding roll 4 which is a part of the web winding device 3 that functions to wind up the web X into a roll. A vacuum device 11 is installed to feed the web X in the running direction while the web is adsorbed onto the surface 1a, and the retard roll 2 is provided with a vacuum device 11 for forwarding the web X in the running direction while adsorbed onto the surface 1a. The winding roll 4 is provided with a vacuum device 12 for transferring and adsorbing the retard roll outer peripheral surface 2a.
A vacuum device 13 is provided for transferring and adsorbing the fixed length web X onto the winding roll outer circumferential surface 4a, and the web is cut into predetermined lengths M on the winding roll outer circumferential surface 1a. The fixed length webs X, A web roll manufacturing apparatus characterized in that it is configured to be able to be transferred onto the outer circumferential surface 4a of a winding roll and sequentially wound into a roll in a web winding section 9.
