<P>PROBLEM TO BE SOLVED: To provide a joint-free cylindrical body, which has an uneven pattern on the surface thereof, adapted as a master model of a casting mold capable of inexpensively and simply manufacturing a casting roll having the linear uneven pattern on the surface thereof. <P>SOLUTION: A method for manufacturing the joint-free cylindrical body having a linear uneven pattern on the surface thereof includes: the lamination process for manufacturing the joint-free cylindrical body made of laminated resin by integrally laminating a non-heat shrinkable and easily deformable hard thin film layer to all over the surface of a joint-free resin cylindrical body having heat shrinkability only in a uniaxial direction of either one of a longitudinal direction and a peripheral direction; and the heat shrinkage treatment process for forming linear protruded and recessed parts crossing a heat shrinkage direction at a right angle by thermally shrinking the joint-free laminated resin cylindrical body in a unidirectional direction to deform the hard thin film layer forming surface in a wrinkled state. <P>COPYRIGHT: (C)2012,JPO&INPIT |
