<P>PROBLEM TO BE SOLVED: To provide a roll for molding a sheet which has high temperature control capability without deteriorating durability and includes a groove formed at the inner surface of an outer cell which differentiates the pliability of a cell in the groove direction. <P>SOLUTION: The roll for molding the sheet includes a cylindrical outer cell 5 for molding the sheet 2 by pressure and an inner cell 6 with a smaller outside diameter than the inside diameter of the outer cell in the outer cell. In addition, the roll is so designed that the temperature of the outer cell is controlled by a temperature control liquid 7 circulating in a space between the outer cell and the inner cell, and a recessed part 12 or a projecting part 22 is formed on the inner circumferential surface of the outer cell. <P>COPYRIGHT: (C)2011,JPO&INPIT |
