Abstract
Process for producing an automobile pane, equipped with a frame of elastomer of a predetermined shape by extruding the elastomer onto the periphery of the pane and beyond the pane and defining at least a part of the shape of the elastomer as it is extruded by positioning mold surfaces beyond the periphery of the pane.
Claims7
Process for equipping a pane (25), having first and second opposite surfaces, with a profiled member of thermoplastic elastomer by means of an extrusion head (10, 39, 45, 59, 69) supplied from an extruder (1) by a pipe (8) and guided along an edge face (27) of the pane, defining the periphery of the pane (25), by a robot (12), the process comprising the steps of:
- (a) placing the pane (25) in a mould (22, 32, 42, 52, 62) with the first surface in contact with a support surface (35, 43, 58, 68) of the mould, with the support surface projecting beyond the edge face (27) of the pane;
- (b) depositing a cord of thermoplastic elastomer (41, 46, 60, 66) from the extrusion head (10, 39, 45, 59, 64) onto said second surface of the pane at the periphery of the pane and onto the support surface which projects beyond the edge face (27) of the pane (25);
- (c) adhering the cord of thermoplastic elastomer to said second surface;
- and
- (d) removing said pane with said cord adhered thereto from said mould.
