Abstract
A method of an emboss pattern process has steps of transferring an emboss pattern onto a thermoplastic resin sheet by using an emboss patterning roller; lustering the opposite face of the embossed face of the thermoplastic resin sheet by using a lustering means having a mirror face member; and peeling the thermoplastic resin sheet from the emboss patterning roller at a lower temperature than a temperature for transferring the emboss pattern. The emboss patterning roller has a roller body, having a face embossed with the pattern, and sealing rings attached on each side face of the roller body, 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.
