Abstract

PURPOSE:To execute the mass-production of a translucent sheet with a tracking channel by copying the fine pattern of a stamper with a compression forming method to give the temperature and the pressure of a suitable condition to the translucent sheet whose thickness is between 300-800mum by a heat press. CONSTITUTION:A stamper 2 of a nickel of an electroforming, in which the cutting of the fine pattern is executed, is fitted to one side of heat presses 1, in which the temperature and the pressure can be controlled, and a polycarbonate sheet 3 of thickness 400mum is inserted between the presses 1. After a preheating is executed to one part of the sheet 3 at the temperature lower than a softening point, for example, at 120 deg.C, it is pressurized for thirty seconds with the condition of 200 deg.C and 10kg/cm<2> and a quenching is executed during the pressurizing. The pressurizing is removed at the temperature lower than 120 deg.C and the sheet 3 is coiled off. Thus, with one procedure for forty seconds, a translucent cover film, to which a fine tracking channel is copied, can be formed.
