Abstract
A device for sealing folders, parcels, and the like. The device comprises a handle which carries at its free end a metal plate containing an image to be printed, a thermoelectric element for heating the plate, and a heat accumulator for maintaining the temperature of the plate. An adhesive thermolabile tape comprises a semi-transparent film of cellulose acetate carrying on one of its faces a layer of colored adhesive material. The film is 'scorched' by the action of the seal so as to display in an indelible way, the image of the latter.
