ABSTRACT:
To obtain a storing method for an elongated plastic deformation member in which the elongated plastic deformation member and a liner are overlapped and wound around a reel for storing the elongated plastic deformation member, whereby partial deformation or deformation nonuniformity of the elongated plastic deformation member can be suppressed.In the present invention, when a liner and an unvulcanized tread member are wound on a reel72and stored, the reel72is supported by a driven roll40and a driving roll30.The reel72is intermittently rotated by alternately repeating normal rotation and inverse rotation, and rotational angles of the reel72are caused to be different before and after rotation of the reel72is stopped, whereby, during storing, a load due to the tread member itself can be imparted more uniformly to the entire circumference of the wound tread member. Accordingly, collapsing deformation of the tread member due to the load becomes uniform in a longitudinal direction of the wound tread member. Consequently, difference in the shape of the tread member does not occur throughout the circumference of the wound tread member.
