    Abstract: An extrusion device includes a sculpted extrusion die comprising a pair of mating die lips having sculpted surfaces and defining a die exit for an extrudate. The contour of the sculpted surfaces is substantially similar to the contour of a juxtaposed surface configured for receiving the extrudate from the die exit of the sculpted extrusion die. The sculpted extrusion die preferably comprises a die lip adjustment mechanism for adjusting a thickness of the extrudate exiting the die exit and the thickness of the extrudate received on the juxtaposed surface. The air gap between the die exit of the sculpted extrusion die and the juxtaposed surface preferably is substantially eliminated by adjusting the distance between the sculpted surfaces and the juxtaposed surface. A method of adjusting a thickness of a substantially continuous sheet of extrudate formed using an embodiment of the sculpted extrusion die of the invention is provided.

    Abstract: The invention relates to the extrusion of tire components with a large change of gauge across their cross-sectional area. It is provided a method and an assembly for extruding such a tire component with an extruder feeding a flow channel with a downstream die opening, whereby a deflector is provided in the flow channel upstream the die opening such that a flow of rubber is slowed down in front of broad portions of the cross-sectional area of the downstream die, avoiding distortion or bending of the extruded tire component.

    Abstract: An unvulcanized rubber extruder that realizes extrusion forming of an unvulcanized rubber extrudate ensuring manufacturing of a high-quality tire without any increase of tire manufacturing steps. In the vicinity of left side end portion, in the drawing, of unvulcanized rubber (A) (rubber chafer part), unvulcanized rubber (B) flows along parallel wall (56) on the downside of main rubber flow channel (34) and flows along second inclined surface (38) on the upside of the main rubber flow channel (34). Simultaneously, apart from the main flow of the unvulcanized rubber (B), portion of the unvulcanized rubber (B) is extruded out in the direction perpendicular to auxiliary rubber flow channel (44) (arrow B direction). Accordingly, in the left side end portion, in the drawing, of unvulcanized rubber (A) (rubber chafer part), it appears that the upside and downside are shut in by the flow of the unvulcanized rubber (B).

    Abstract: The invention relates to a calibrating plate for an extrusion die for producing plastic profiles, comprising a substantially plate-shaped basic body (21), in which an opening (22) for guiding and calibrating the plastic profile (23) to be produced is provided, with at least one insert part (1) made of a material with high hardness being inserted into the basic body (21), which insert part comprises at least one holding section (2) and a shaping section (3), with both the holding section (2) as well as the shaping section (3) being formed partly as cylindrical surfaces with generatrices parallel to the extrusion axis (6), and with the insert part (1) being held in the axial direction in the plate-shaped basic body (21) by a delimiting stop (5). A longer service life and a simpler adjustment can be achieved in such a way that the holding section (2) comprises a groove (4) which extends in the direction of extrusion (6a), and that the delimitation stop (5) is arranged at one end of the groove (4), which stop protrudes from the groove (4).
