Abstract: A method for producing a profiled bead made of a plastic, particularly of a polymer, on a piece, particularly on a window pane. In the method at least a partial portion of an edge region or lateral face region of a surface of the piece is brought into contact with a forming face. The plastic is deposited stuck to at least part of the periphery of a surface of the piece untouched by the forming face and the external dimensions of the profiled bead formed are also defined by the forming face. The forming face is pressed against the edge region or lateral face region of the fixed piece using a flat support, the shape of which can vary under the pressure of a fluid. This then gives a better matching of the forming face to the contour and to any dimensional discrepancies of the piece.

Abstract: A window pane (1), in particular an automobile window pane, is adhesively bonded to a frame (8) of a window opening by an adhesive bead (6), and carries a profiled bead (3) provided with a recess (4) extending longitudinally and a tear-away cord (8) laid therein. Tear-away cord (8) is designed for breaking the adhesive bond between window pane (1) and frame (7). A contact surface is provided for adhesive bead (6) alongside profiled bead (3). In the fitted state, recess (4) is open toward adhesive bead (6) so that the tear-away cord may be pulled without exerting a high force directly in the adhesive bead that abuts the opening of the recess.

Abstract: An assembling element, particularly for vehicle bodywork, is provided with a fastening edge (14) onto which an elastic weatherstrip made from an extrusion-compatible elastomer is extruded. The fastening edge (14) is provided with anchoring notches (17). In a variant, the elastomer of the weatherstrip and the surface of the fastening edge (14) do not form a mutual adhesive joint and the anchoring notches (17) are provided so that the weatherstrip, which is anchored solely mechanically, can be detached if required from the fastening edge (14) and, without further processing, subsequently be refastened mechanically to the fastening edge. In a second variant, the anchoring notches (17) prevent play and make it possible substantially to enhance the connection between the strip and the edge.

Abstract: A method and apparatus for extruding a plastic spacer directly on an object, in particular on the periphery of window glazing, such as automobile glazing intended to be glued into the opening of a vehicle. In particular the invention relates to properly producing the connection zone between the end and the beginning of the extruded spacer when it forms a closed loop. According to the invention the beginning of the spacer and the remainder of the loop are extruded, with the exception of the connection zone. The object is then provided with an applied anti-adhesive deposit surface that is continuous with the surface of the object. The path of the extrusion head is diverted in relation to the surface of the object so that the extrusion occurs on the applied deposit surface, proximate to and beyond the beginning of the spacer loop. The extruded spacer is then allowed to harden and the extremities of the spacer are cut and adjusted to properly complete the connection.

Abstract: This invention concerns a device used in the process of manufacturing an automobile pane 1 equipped with a polymer frame 52 placed on the edge of the pane 1. The frame 52 is extruded onto the pane 1 which can be moved by means of a suitable support in such a way that the edge of the pane travels through a recess in an extrusion head 25 and 40. The recess of the extrusion head 40 preferably includes a U-shaped jaw 41 straddling the edge of the pane. At the front extremity of the two half-jaws of the U-shaped jaw 41 there are disposed sealing ledges or shoes 42 and 43 which are movable perpendicularly to the surfaces of the pane and which, during extrusion, bear upon the surfaces of the pane. Alternatively, the extrusion head can include a fixed jaw where the sealing ledges or shoes slideably and sealingly contact the plate.

Abstract: A motor vehicle glazing (1) prepared for installation according to the adhesive process is provided with a profiled spacer (8) produced by extrusion of an extrudable polymer directly onto glazing (1) and subsequent setting. During installation of glazing (1) in the window opening of the motor vehicle body, profiled spacer (8) acts as an intermediate member between glazing (1) and assembly adhesive extrudate (13). Profiled spacer (8) is provided along its outer periphery with a lip portion (10) projecting beyond peripheral area (3) of glazing (1). In the installed position of glazing (1), lip portion (10) rests against the window frame flange (4) running parallel to peripheral area (3) of glazing (1) and acts, upon insertion of the glazing during the setting process of assembly adhesive (13), as a support and centering element for glazing (1).
