Provided is an apparatus capable of preventing the intrusion of particles into spaces in a web substrate roll. The apparatus forms web substrate rolls by continuously winding a long web substrate (21), on which edge tabs (14) have been installed, in a chamber (5) under vacuum or under reduced pressure, and is provided with: a winding section (4) for winding the web substrate (21) and overlaying the edge tabs (14); and a filler-supplying section for adding a filler (20) between portions of the web substrate (21) that are adjacent to each other in the radial direction and are between the two edge tabs (14) by supplying the filler (20) to the web substrate (21) that is being wound on the winding section (4).
A web substrate roll-forming apparatus for forming a web substrate roll by continuously winding a long web substrate having edge tabs installed, respectively, in both ends in the width direction thereof in a chamber under vacuum or reduced pressure, the apparatus comprising:
A web substrate roll formed by winding a long web substrate having edge tabs installed, respectively, in both ends in the width direction thereof in a manner overlaying the edge tabs, the roll comprising a filler added into an in-roll clearance formed between portions of the wound web substrate adjacent to each other in the radial direction so as to prevent foreign matters from intruding into the in-roll clearance.
