METHOD FOR SEPARATING LAMINATE, AND SEPARATION DEVICE

摘要

PROBLEM TO BE SOLVED: To separate a laminate consisting of a die and a molding without damaging the grooves for formation of a lens. SOLUTION: While the center part of the laminate (6) of the die (2) and the molding (3) is pressed, the peripheral part of one layer is pulled in a plurality of positions at a time to the opposite direction to the pressing direction so that the layer is separated from the peripheral part of the other layer and that the separation is made to proceed to the center part to separate the molding (3) from the die (2). Separation between the die and the molding is made to proceed from the peripheral part to the center part in such a manner that the part once separated is not brought into contact again with the corresponding part. Thus, the molding can be separated from the die without damaging the grooves for formation of the lens.
