Abstract
PURPOSE: To provide a loyally embossed pattern to an original sheet by arranging the plural rolls around an embossed roll so as the nips between the rolls become tighter as the original sheet proceeds and passing the softened original sheet through these nips.
CONSTITUTION: The plural opposing rolls 61, 62, 63, 64 are arranged around an embossed roll 60 and the nips between both rolls 601, 602, 603, 604 are adjusted to become tighter successively. Then, a thermoplastic original sheet 10 is sent through these nips 601, 602, 603, 604 in a softened state at high temperature. Thus, cooling shrinkage of the original sheet 10 is offset by the thickness change of the original sheet 10, so the reversed pattern loyal to the pattern embossed on the roll 60 can be obtained on the sheet 10.
