초록 ▼

An extrusion head is disclosed, for extruding weather strips of elastomeric material, particularly for motor vehicles, of the type comprising an anchoring section and a longitudinal sealing section in the form of a tab coextruded with the anchoring section. The extrusion head comprises a die with an extrusion orifice having a shape corresponding to the cross-section of the weather strip to be extruded, and a deflector device adapted, when actuated, to change the inclination or orientation of the sealing section relative to the anchoring section during extrusion.

대표청구항 ▼

An extrusion device for extruding a weather strip of elastomeric material having a substantially flat anchoring section and a longitudinally sealing section in the form of a tab coextruded with the anchoring section and connected to the anchoring section along a straight line with the tab being inclined to one side of a plane perpendicular to the anchoring section along said straight line, said extrusion device comprising an extrusion head having a die with a fixed configuration extrusion orifice corresponding to the cross-section of the weather strip to be extruded, moveable deflector means disposed adjacent said extrusion orifice and adapted to be moved into and out of engagement with said tab to selectively change the inclination of said tab relative to said anchoring section from one of said plane to the other side of said plane; said moveable deflector means comprising a deflector member having a deflection surface adapted to contact said tab and having an initial profile at one end thereof corresponding essentially to the profile of one face of said tab as it emerges from said extrusion orifice, a final profile at the opposite end thereof having an inclination different from that of the initial profile and a continuously variable intermediate surface extending from said initial profile to said final profile, and means for mounting said deflector member for movement relative to said extrusion orifice between a rest position in which said deflection surface does not interfere with the weather strip leaving the extrusion orifice and a working position in which the deflection surface is disposed adjacent said extrusion orifice with said initial profile coinciding with the corresponding portion of said extrusion orifice whereby the tab upon leaving the extrusion orifice slides in contact with the deflection surface and is plastically deformed to gradually assume the final profile of the deflection surface. A method for extruding weather strips of elastomeric material comprises extruding a strip of elastomeric material from a fixed configuration extrusion orifice in an extrusion head having a substantially flat anchoring section and a longitudinal sealing section in the form of a tab connected to the anchoring section along a straight line and inclined relative to said anchoring section on one side of a plane perpendicular to said anchoring section along said straight line and selectively moving a deflector member having a variably contoured deflection surface with an initial profile coinciding with the corresponding portion of said extrusion orifice into engagement with one surface of said tab subsequent to the extrusion of said strip to gradually deflect said tab to change the inclination thereof relative to said anchoring section.
