<P>PROBLEM TO BE SOLVED: To successfully correspond to a case where a hose is arranged and a condition required for the hose. <P>SOLUTION: Constituent materials 1, 2 respectively supplied from a plurality of supply portions are spirally wound on a molding rotating shaft, these wound portions are axially juxtaposed, and corresponding width direction ends are fixed in the adjacent wound portions, thereby composing a pipe wall section. With respect to the other supply portion, at least one supply portion is relatively moved forward and backward in the axial direction of the molding rotating shaft, thereby changing a relative positional relationship in a radial direction between the wound portions of the constituent materials 1, 2 supplied from the supply portions. <P>COPYRIGHT: (C)2012,JPO&INPIT |
