ABSTRACT:
An adhesive support assembly for attaching at least one article. The support assembly includes a bed of pressure-sensitive adhesive having an upper surface. The adhesive bed which is also heat-meltable, is held within a tray or other walled container. This container is sufficiently heat-resistant to allow heating the support assembly to at least the ring and ball softening temperature of the adhesive so that when the upper surface of the adhesive bed has become shopworn or loses adhesive strength from repeated use and/or adhesion of dirt, the assembly can be heated to at least this softening temperature to restore this adhesive strength.
