摘要

Device for the liquefaction of solid adhesives, in the form of a fusible bar, under the effect of heat, of the type comprising a heatable body provided with a guide channel for the stick of adhesive and an electrical heating device that generates in the guide channel a temperature corresponding at least to the melting temperature of the adhesive so that a stick of adhesive introduced into the guide channel liquefies during the insertion movement and flows in the liquid state at the mouth of the guide channel, characterized in that the device electric heating is a ptc heating resistor (positive thermal coefficient resistor) that is arranged with an axial direction component in relation to the guide channel and extends in this direction over a length that corresponds to several times the average diameter of the guide anal.
