Abstract

PURPOSE:The opening part of the outlet of die is formed with a peripheral surface of rolls with negative cut of uneven pattern and the pattern is transferred to the extruded material of synthetic resin, thus producing continuous formed product of synthetic resin having uneven pattern on the surface. CONSTITUTION:Die 2 that has drum-shaped forming surface on the center part and outlet 22 with a bended surface 23 on top and bottom, right and left sides at the edges of the outer walls is fixed on the edge of extruder 1 on the flat base 21. Revolving rolls 26-29 with uneven pattern on their surface are fixed between opposite surfaces of L-shaped supporting plates 241-244 that are formed around the outlet 22 at base 21. The molten synthetic resin is extruded from cylinder 11 in extruder 1 through outlet 22 and formed on the peripheral surfaces of revolving rolls 26-29 and simultaneously the uneven pattern that is negatively cut on the peripheral surface is transferred to the formed synthetic resin, thus producing continuous formed products of synthetic resin with uneven pattern on the surface.
