  • Process for producing shaped synthetic resin articles varying in shape of longitudinal section
    Patent number: 4009237
    Abstract: A shaped synthetic resin article varying in cross-sectional area and shape of longitudinal section along at least a part of the length is continuously produced by introducing a molten synthetic resin composition, extruded from an extruder die, between at least one pair of rolls rotating in the direction of extrusion so that the rolls of each pair contact each other on their periphery, the peripheral surfaces of the rolls being engraved so as to form a cavity corresponding to the shape of said shaped article when the rolls of each pair contact each other while being rotated, in which cavity the molten resin composition is remolded into an article having the desired shape and at the same time the surplus resin composition overflowing from said cavity is cut off by the edges of said rolls contacting each other, and then cooling the molded article to solidify the same.
