摘要:
[Object] An apparatus and a method for producing optical sheeting with which increased productivity can be achieved while maintaining the accuracy of produced optical sheeting.[Solution]An apparatus 1 for producing optical sheeting includes: a first rotating roll R1 configured to be heated; a second rotating roll R2; a first belt mold S1 that has molds for optical elements on a surface thereof, and is configured to turn around the first rotating roll and the second rotating roll; a sheet feeding means D2 configured to feed synthetic resin sheeting onto a surface of the first belt mold S1, a second belt mold S2 configured to be pressed against the first belt mold S1 and to turn with the turning of the first belt mold S1; and at least two pressure rolls R3 and R5 around which the second belt mold S2 is mounted and which is configured to press the second belt mold S2 against the first belt mold S1, wherein the pressure roll R5 is arranged at a position where the second belt mold S2 comes away from the first belt mold S1 and cooled at a surface thereof.
