Abstract

PURPOSE: To manufacture a sheet formed with fine recessed and protruded patterns sharply on a surface thereof by a method wherein a pasty thermoplastic resin is coated on an endless belttype form body formed with the fine recessed and protruded surfaces, thereafter, is treated with a heat treatment.
CONSTITUTION: An endless belttype form body 3 formed with fine recessed and protruded surfaces thereon is constituted and a thermoplastic resin 5 softened into a pasty state is coated on the form body 3 when it is driven and progressing. Then, the thermoplastic resin 5 is heat-treated in a heating furnace 7, thereafter, is separated from the form body 3 to manufacture a formed sheet 10. Further, a packing base material 11 may also be laminated on the formed sheet 10. According to said method, the sheet formed sharply with fine recessed and protruded patterns on a surface thereof can be manufactured.
