パリソンの押出成形装置。 An apparatus for extrusion molding a parison, which includes a rotatable annular die having an uneven portion on the inner circumferential surface of the lower end, and a rotatable annular die arranged concentrically inside the die and having an uneven portion on the outer circumferential surface of the lower end. a core; and an annular die slit formed between the die and the core to extrude the molten resin; the die and the core are arranged so that their uneven parts face each other so that the width of the extrusion port side of the die slit is adjusted in the circumferential direction; A parison formed in a mesh shape with a plurality of intersecting protrusions on the inside and outside is extruded from a die slit while rotating in opposite directions in different states.
Parison extrusion characterized by extruding a parison of uniform thickness from a die slit with the die and core relatively displaced in the direction of their respective rotational center lines so that the width on the die slit extrusion port side is made equal in the circumferential direction. Molding equipment.
