Method of emboss pattern process, emboss pattern processing apparatus and embossed sheet

摘要

A method of an emboss pattern process has steps of transferring an emboss pattern onto a thermoplastic resin sheet (11) by using an emboss patterning roller (13); lustering the opposite face of the embossed face of the thermoplastic resin sheet by using a lustering means (15) having a mirror face member; and peeling the thermoplastic resin sheet (11) from the emboss patterning roller (13) at a lower temperature than a temperature for transferring the emboss pattern. The emboss patterning roller (13) has a roller body (17), having a face embossed with the pattern, and sealing rings (18A,18B) attached on each side face of the roller body (17), in which the roller body and the sealing ring has a passage for flowing a cooling medium from one sealing ring through the roller body to the other sealing ring.
