Abstract

PURPOSE: To obtain the illustrated gramophone disk without causing tears on a printed paper and deformation of sound grooves by a method wherein a surface material made from a heated and gelled thermoplastic resin, the printed paper and a reinforcing material are inserted into a set of press dies in a specific order and heated under pressure.
CONSTITUTION: Stampers 3, 4 are arranged respectively inside of an upper and a lower metal mold 1, 2 and an central axis 5 is provided on the lower mold 2. Into that central axis 5 are inserted sequentially the preheated and gelled surface material 6 made from thermoplastic resin, then the printed paper 7 with pictures and writings printed, the reinforcement material 8 such as a thermoplastic resin sheet etc., then the printed paper 9 similar to the printed paper 7, moreover the surface material 10 similar to the surface material 6 in these order. After that, the metal moldes 1, 2 are heated and compressed, the surface materials 6, 10 are flowed radially around the axis 5 as the center to form the sound grooves. Under such states the surface materials are cooled. The surface material and the reinforced material are hardened in a body to obtain the intended illustrated disk.
