  • Releasable adhesive joint, a method for establishing a releasable adhesive joint and an apparatus for releasing such adhesive joints
    Patent number: 5620794
    Abstract: The invention provides a releasable adhesive joint between two elements. The two elements are fixed to each other by means of an adhesive bead or by means of two or more adhesive beads. The adhesive joint comprises a heatable separating member closely fitting the adhesive bead or embedded in the adhesive bead, or closely fitting or embedded in one of the adhesive beads. The heatable separating member looses the adhesion to the closely fitting parts of the adhesive joint or is destroyed upon heating the heatable separating member to a temperature at which the adhesive bead is not yet damaged, thus releasing the parts of the adhesive bead closely fitting the heatable separating member. This releasable adhesive joint is especially useful in fixing vehicle glass panes to a vehicle body frame.
