Abstract

PURPOSE:To obtain the thermoplastic resinous sheet eliminating a drawdown from a resin having a high fluidity by feeding an extrusion sheet material between a plurality of cooling rolls by an endless belt stretched over the cooling rolls provided foreward of a T-shaped die. CONSTITUTION:In the foreward direction of the T-shaped die 1, there is provided and bridged the endless belt 4 made of nylon and the like over three cooling rolls 3, 3' and 3'' and three supporting rolls 5, 5' and 5''. The extrusion sheet meterial 2 is carried by the endless belt 4 and fed between the cooling rolls 3, 3' and 3''. The extrusion sheet material goes through these rolls 3, 3' and 3'' smoothly to form an extrusion sheet without drawdowns. EFFECT:This manufacturing method can be applied to the embossing shaping process.
