Abstract
A device for guiding a rod-shaped member formed of a gluing material which is softened by heat through insertion into a guide channel of a heating apparatus, the device comprising an elastic, flexible cartridge arranged on a heater and secured thereto by a metal sleeve. The metal sleeve extends beyond the heater and surrounds a portion of the cartridge for conducting heat to a section of the cartridge removed from the heater. A small gap is provided between the cartridge and the portion of the metal sleeve surrounding the cartridge to allow for an enlargement in cartridge diameter. The hollow interior of the cartridge is provided with an inwardly directed lip-shaped circumferential edge which cooperates with an inserted gluing material rod to form a seal therebetween. The metal sleeve is preferably a helically coiled metal wire.
