  • Method and apparatus for producing a seal including a portion having a wall of variable thickness
    Patent number: 7883332
    Abstract: The method makes it possible to produce a seal (1) of an extruded plastics material, including a tubular section (3) with a wall of variable thickness (WT), using a distribution chamber having a terminal die plate (12) with an annular extrusion orifice (15) formed therein, corresponding to the cross section of the tubular section (3). A chamber (18) is formed in the distribution chamber in communication with the extrusion orifice (13) and into which an elastomeric material is fed for forming the tubular section (3). The chamber (18) of the distribution chamber is in open communication with the outside environment by a passage (21) which is separate from the extrusion orifice (13) and is provided to carry a flow of elastomeric material coming from the chamber (18).
