Abstract
A process is described for installing an automobile glazing by direct gluing in which an extrusion nozzle deposits an adhesive mass in bead form on one of two surfaces to be glued. The bead can either be used directly for gluing or, after hardening, act as a profile placed on glazing which is used as an intermediary between the glazing and a second gluing bead. Embedded within the bead are a plurality of high tensile strength flexible wires. During the removal of the glazing the wires are used to shear the bead where they have been introduced, i.e., either in profile or in the second gluing bead. The wires are positioned so that each has to shear only a part of the section of profile or of the bead.
Claims16
A process for installing an automobile glazing into an opening by depositing between the glazing and the opening an adhesive mass in bead form and a plurality of high tensile strength wires for shearing said bead, said wires being adapted to shear different parts of said bead, at least some of said wires being embedded in said bead.
A device for embedding a plurality of flexible wires in a bead of glue comprising an extrusion nozzle (40) having a calibrated opening (42) to deposit an adhesive mass with high viscosity,
- at least two passages (43) each of which conducts a flexible wire (23, 24) into the adhesive mass, and
- at least two tubular guides (49, 50) each of which feeds a wire (23, 24) into one of said passages.
An automobile glazing intended for direct gluing comprising on its edge a profile bead (20), in which at least two flexible wires (23, 24, 25, 26, 27, 28, 29) are located at different positions in said bead with ends that exit laterally from said bead, said wires being adapted to shear different parts of said bead, whereby by pulling successively on the ends of said wires, said wires are used to shear said bead.
A process for installing an automobile glazing into an opening by depositing between the glazing and the opening an adhesive mass in bead form and a plurality of separate high tensile strength wires for shearing said bead, said wires being parallel to each other and to said bead and being adapted to shear different parts of said bead, at least some of said wires being embedded in a cross-section of said bead.
