ABSTRACT:
A hot-melt dispenser or glue-gun is provided with a two-element sleeve at the inlet to the melt chamber, the elements being separated by a thermal barrier to reduce heat flow from that sleeve element in direct contact with the melt to the other sleeve element thereby inhibiting undue softening or even premature melting of the rod of thermoplastic composition held within the sleeve as it is fed to the melt.
