Abstract
PURPOSE:To mold said resin molded product of a bush, a band etc. continuously without using a large mold, by combining a disk having a notch part and a disk without it and making the two into a pattern roll. CONSTITUTION:Resin molding material is fed from a hopper 6 of an extruder 5 and sent to a die 8 by a screw 7. Melted resin falls from the resin passage 9 of the die 8, passes through a clearance between a wedge like die 10 and a rear part 11 and is extruded on the peripheral face of a pattern roll 12. Resin extruded from the passage 9 of the die 8 is introduced between a declined face 10a inside the wedge like die 10 and the roll 12 and pushed to the declined face 10a and a groove 10 b by an extruding force generated due to the rotaion of the roll 12 to an arrow direction. It is forced into the notfh part 18 shaped at the peripheral face of the roll 12, cooled, solidified and taken off as a train of a molded product 13.
