Use of a strip of self-adhesive film for temporary bonds
First Claim
1. An adhesive element for a temporary bond, comprisinga) a piece of stretchable film carrying adhesive on both faces,b) means rendering one adhesive area on each face non-adhesive, the resulting non-adhesive area on one face being aligned with the adhesive area on the other face to provide a stretchable film having one adhesive area and one non-adhesive area per face,c) the adhesive being such that upon stretching in its plane it loses adhesiveness,d) whereby upon joining two surfaces by applying one face of the element to one surface and applying the other surface to the other face of the element they are joined and subsequently by moving one of the surfaces laterally the adhesive stretches, loses its adhesiveness and the surfaces are released from one another and from the elementwherein said element has a thickness of about 25 to 3000 μ
