ABSTRACT:
The invention relates to an applicator comprising a) an elongated chamber (3) having an opening for a glue stick and a nozzle (6) for distributing melted glue, b) means for gradually pushing the stick into the chamber (3) and c) two heating elements (131, 132), each of which comprises a channel (151, 152) made from an electrically resistant material and which can be connected to an electrical power source. Said channel (151, 152) is formed on an electrically insulated surface of a substrate (141, 142) which is arranged so as to be in thermal contact with a mass of glue contained in the chamber (3). The heating element (131, 132) is applied against an external conformal surface (21, 22) of a heating body (2), one surface of which defines said chamber (3). The heating body (2) is made from a heat-conducting material.
