Abstract

The element pref. comprises a folded paper, which may be impregnated with resin, or a felt or porous plastics, folded into a hollow cylinder, with the ends glued together or held by two folds. The cylinder is glued on its upper and lower faces. The element may have two cheek plates cut from very flexible, open-cell polyurethane foam, glued on one face. The compatible glue uses a volatile solvent. Immediately after gluing, the folded material and the cheek plates are brought into contact under slight pressure, with perfect adhesion and absolute sealing, without use of moulding processes. May be used on motor vehicles.
