<p><P>PROBLEM TO BE SOLVED: To provide a molding method of a rubber sheet improving shrinkage of a rolled rubber sheet, even when a material of a large shrinkage is used, and to provide the molding apparatus of the rubber sheet. <P>SOLUTION: The molding apparatus of the rubber sheet includes a stretching device 4 provided downstream in the moving direction of the rubber sheet (s) from a calender apparatus 1 forming the rubber sheet (s) by rolling unvulcanized rubber. The stretching device 4 enlarges the width dimension of the rubber sheet (s) to 110% or more of the original dimension in the width direction of the rubber sheet (s) orthogonal to the moving direction of the rubber sheet (s). <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
