Abstract
(EN)
In one embodiment, a long strip member (100) with reinforcing material attached continuously in the longitudinal direction and having joints formed at the edges on the opposite sides is fed out, and the adjoining joints are jointed to make a spiral pipe (S). A curling device (3) has a roller for feeding the strip member (100) with reinforcing material and a curl guide. By using the curling device (3), an arcuate curl having a radius of curvature substantially equal to or shorter than that of the spiral pipe (S) is formed in the adjacent strip member (100) with a reinforcing material, and then it is deformed spirally and plastically. Consequently, the spiral pipe (S) can be made while suppressing the action of a restoring force for restoring the strip member (100) with reinforcing material so as to have the original radius of curvature.

Dans un mode de réalisation, un long élément de bande (100) avec un matériau de renfort fixé continuellement dans le sens longitudinal et ayant des joints formés aux bords des côtés opposés est amené, et les joints adjacents sont joints pour réaliser un tuyau à spirale (S). Un dispositif d'ondulation (3) présente un rouleau pour amener l'élément de bande (100) avec le matériau de renfort et un guide d'ondulation. En utilisant le dispositif d'ondulation (3), une ondulation arquée ayant un rayon de courbure sensiblement égal ou inférieur à celui du tuyau à spirale (S) est formée dans l'élément de bande adjacent (100) avec un matériau de renfort, et ensuite elle est déformée en spirale et plastiquement. Par conséquent, le tuyau en spirale (S) peut être réalisé tout en supprimant l'action d'une force de rétablissement, afin de rétablir l'élément de bande (100) avec un matériau de renfort de façon à obtenir le rayon de courbure original.

 一実施形態では、両側縁部に接合部が形成され、長手方向に連続する補強材が装着された長尺な補強材付き帯状部材(100)を供給し、互いに隣接する接合部同士を接合して螺旋管(S)を製管する。巻き癖形成装置(3)は、補強材付き帯状部材(100)を送りローラおよび巻き癖ガイドを備える。巻き癖形成装置(3)を用いて、隣接する補強材付き帯状部材(100)に、螺旋管(S)の曲率半径と略同等もしくは同等以下の曲率半径の円弧状の巻き癖を形成し、これを螺旋状に塑性変形させる。これにより、補強材付き帯状部材(100)に元の曲率半径に復元しようとする復元力が作用するのを抑制して螺旋管(S)を製管できる。
