WIPO Patent Application WO/2014/068703
Kind Code:
A1
Abstract:
This paper tube manufacturing machine has a movement path that guides movement of a paper web having a plurality of cut-in grooves and a web bending device that forms a paper tube by a process of bending the paper web. This web bending device includes a garniture belt, a tube forming section, and an applicator. In the moving process for the paper web, the tube forming section maintains the inner surface of the paper web in a free state while forming the paper web into the paper tube continuously using the garniture belt, so that the paper tube has a lapped part in which both side edges of the paper web overlap each other. Meanwhile, the applicator applies an adhesive to one of the two side edges on the paper web before the lapped part is formed to make the two side edges adhere to each other.
