DISPOSITIVO DE EXTRUSAO DUM PERFIL NA PERIFERIA DA SUPERFICIE DUM VIDRO

摘要

In order to extrude onto a motor-vehicle glazing panel a seal (6) placed at the periphery (11) of its surface (25) which comprises a lip (10) for the centring and the sealing of the positioned glazing panel, a two-channel nozzle (16,17) is used. …The channel (17) serves for the extrusion of the peripheral lip (10). It comprises an obturating device (26) which enables the flow rate of material from the channel to be regulated. The regulating of the obturator (26) is carried out as a function of the radii of curvature (R) of the perimeter of the glazing panel. ……
