1 is a paper tube cap mounting device, and the paper tube cap mounting device 1 is roughly divided into a plurality of presses having an arc-shaped press surface 2a on the outer periphery and a tapered surface 2b expanding outward on the inner surface. A piece 2, a retractable piece 3 that comes into contact with the tapered surface 2b of the press piece 2 and expands the outer periphery of the press piece 2 outward, and a retractable piece 3 that comes into contact with the retractable piece 3 and expands the outer periphery of the press piece 2 outward. The paper tube cap attachment device 1 expands the outer periphery of the press piece 2 outward to expand the cap and attach it to the paper tube.
そして、プレス駒２の隣り合う一方は、山形の
形状で、他方は、該山形を受け入れる谷形状を有
している。 One of the adjacent press pieces 2 has a chevron shape, and the other has a valley shape to accommodate the chevron shape.
なお、３１は、出没駒３に設けられた張り部
で、張り部３１は、口金を紙管に食い込ませるも
のである。 In addition, 31 is a tensioned part provided on the retractable piece 3, and the tensioned part 31 allows the cap to bite into the paper tube.
又、１２は、復帰のバネであり、１３は、カバ

凸状部の形成が防止される。 At this time, one of the adjacent press pieces 2 has a chevron shape, and the other side has a valley shape to receive the chevron shape, so that the outer periphery of the press piece 2 comes into diagonal contact with the mouthpiece, and the press piece 2 Even if the press surface 2a has a gap, the outer periphery of the press piece 2 contacts the die obliquely, and the part of the die that does not come into contact with the press piece 2 is also stretched, leaving no trace on the die, unlike conventional methods. This prevents the formation of convex portions on the base.
