  • Patent number: 8506280
    Abstract: The invention comprises a die apparatus including a flexible lip for adjusting a gap between the flexible lip and a second lip. The apparatus include a cross-bar contacting the lip and extending substantially the length of the lip, where the cross-bar is connected to linear moving members. The linear moving members may be moved, for instance, through pivoting pivot members. The pivoting members may pivot by adjusting a slide bar. As a result, the dimensions of the gap may be changed by moving the slide bar in a first direction or a second direction.

  • Patent number: 8496460
    Abstract: A method and apparatus is provided for distributing material through a multilayer pipe extrusion die. A first flow passageway, having a first cross-sectional area and extending along a first flow direction, may be connected to a second flow passageway, having a second cross-sectional area substantially the same as the first cross-sectional area of the first flow passageway, to provide a second flow direction different from the first flow direction of the first flow passageway. A conical passageway may extend from the second passageway toward a dispensing outlet. Material may be distributed from the first flow passageway into the second flow passageway. The method and apparatus may generally maintain the same flow properties of the material at a point before and after the connection of the first flow passageway and the second flow passageway. The flow properties of the material may be altered proximate to the outlet.

  • Patent number: 8414284
    Abstract: An apparatus forms an elastomeric strip. The apparatus includes a roller and an adjustable surface. The roller has a cylindrical surface. The roller rotates at a predetermined angular velocity. The adjustable surface confronts the cylindrical surface and has a first stationary position relative to the cylindrical surface such that the apparatus forms an elastomeric strip having a first thickness. The adjustable surface is adjustably pivotable relative to the cylindrical surface such that the adjustable surface moves to a second stationary position for forming an elastomeric strip having a second thickness.

  • Patent number: 8273276
    Abstract: A roller die preformer for use in an extrusion system to form wide extruded components, such as a rubber tire tread, on a surface of a roller. The roller die preformer includes a flow inlet, a flow outlet and a laterally expanding flow channel extending from the flow inlet to the flow outlet. A flow restrictor is configured within the flow channel to urge the flow of material toward the lateral extremities of the flow channel to thereby form an extruded component at the flow outlet having a lateral width which is greater than the lateral width of the flow inlet of the preformer.

    Abstract: A device for expanding a tubular elastic body, the device comprises a rigid tube to be introduced into at least a part of the elastic body and keep the elastic body in an expanded state, and an expansion means adapted to expand the elastic body and arranged to be introduced into a first end of the rigid tube. The expansion means is adapted to be movable inside the rigid tube and when the expansion means is fully introduced in the rigid tube, the expansion means protrudes at a second end of the rigid tube and thereby forms a transition between the rigid tube and the expansion element. One end of the expansion means is provided with a radially resilient expansion element with a width decreasing in the introduction direction of the expansion means into the first end of the rigid tube.
