ABSTRACT:
The invention relates to attachment of metal edge strips to a sliding glass sheet for an automobile, the function of the strips being to guide or hold said sheet. Edge strips are attached to a sliding glass sheet by means of an adhesive which has high adhesion to glass, such as an adhesive comprised of polyurethane with other components.
According to the invention, the adhesion of the adhesive to the edge strips is enhanced by furnishing the leg of the strip, which contacts the adhesive, with apertures, grooves, notches, channels and hollows. It has been found that the contact surface between the adhesive and the leg is at least twice as important as that between the adhesive and the glass.
