<p>PURPOSE:To obtain thick rolled polymer sheet by a method wherein a plurality of polymer films or sheets, each of which is uniaxially stretched by rolling and which are brought in the condition being interposed by adhesive film layer, are continuously heated up to a predetermined temperature and, that, fixed by pressure and cooled by being pressed down cooling rollers. CONSTITUTION:Each coiled stock 1 is heated by being brought into repeated contact with a group of rollers 2 and pressed down one pressure roller 3, which is heated up to a predetermined temperature, and, in succession, cooled with cooling roller 4 and wound up in coil 5. By laminating uniaxially rolled films obtained as described under the condition pinching adhesive films among them, a coil 6 is obtained. The laminated films are heated in a heating furnace 8, in which four heating rolls 7 are arranged, up to the predetermined temperature. Pressure rolls 9 arranged near the outlet of the heating furnace are cooling rolls, the temperature of which is kept at constant. At compression, the matrix of the stock is held just below its melting point and the adhesive film melted. Simultaneously with pressing down, the heat of the laminated films is removed by the rollers, and consequently the temperature of the films lowers. In this case, when the thickness of the material of the films is large, the cooling of the films is performed by adding the cooling rollers 10. After cooling, the films are cut in sheets 12 with a cutter 11.</p> |
