Method and apparatus for changing the inclination or orientation of a longitudinal tab of an extruded weather strip for motor vehicles during its extrusion and weather strip thus obtained.

摘要

An extrusion head (10) is disclosed, for extruding weather strips (1) of elastomeric material, particularly for motor vehicles, of the type comprising an anchoring section (2) and a longitudinal sealing section in the form of a tab (3) coextruded with the anchoring section (2). The extrusion head (10) comprises a die (11) with an extrusion orifice (12) having a shape corresponding to the cross-section of the weather strip (1) to be extruded, and a deflector device (18) adapted, when actuated, to change the inclination or orientation of the sealing section (3) relative to the anchoring section (2) during extrusion.
