ABSTRACT:
An apparatus for liquefying a thermoplastic plastic, in particular an adhesive on the basis of polyurethane, comprises a heatable sealed supply container having an upper portion for receiving a downwardly open transport container for the thermoplastic plastic and a lower portion serving as buffer volume, a heating means for heating the thermoplastic plastic disposed in the transport container, a base portion arranged beneath the supply container and thus beneath the transport container and accommodating a collecting trough for the liquefied thermoplastic plastic and a cover at the upper end of the supply container. In addition, a heating device, either a heat radiator or a contact heating means, is integrated into the cover to heat the bottom of the transport container and thus increase the discharge rate.
Expediently, a resiliently mounted heating plate which comes to bear on the bottom of the transport container is provided in the cover.
