Abstract

PURPOSE: To obtain sheets of methacrylic resin having a shibopattern, which hardly disappear during a heat-molding operation or which has an excellent survivability, by setting the temperature of the surfaces of shibo-rolls at a level near of higher than the heat-molding temperature.
CONSTITUTION: A methacrylic resin extruded in the form of a sheet through a sheet molding die 2 is passed through three rolls 3, 4, 5 while the sheet is hot, to form a shibo-pattern thereon. In order to form a shibo-pattern on one side of the sheet, the roll 4 is used as a shibo-roll. In order to form a shibo-pattern on both sides of the sheet, the rolls 4, 5 or 3, 4 are used as shibo-rolls. The temperature of the surface of these rolls is set at a level near or higher than the heat-molding temperature. Thus, a sheet A of methacrylic resin having a shibo-pattern can be obtained, which has a rough surface reproduced perfectly by the roughness of the shibo-rolls and which has an excellent frosted outer appearance and a high diffusing effect. Even when the sheet A thus obtained is subjected to heat-molding, such a vacuum molding and knock-out molding, it does not adversely affect the shibo- pattern at all.
