HEATER MODULE FOR AN APPARATUS FOR MELTING AND DISPENSING THERMOPLASTIC MATERIAL

摘要

Abstract of the DisclosureA heater module adapted to be used in an apparatus for meltingand dispensing thermoplastic material, with other like modules forforming a pre-melt and/or a melting stage for heating the thermoplasticmaterial. Each module is of uniform construction and includes an elongatedcore having a plurality of longitudinally spaced first fins projectingfrom one side of the core and second fins projecting from the other sideof the core, but longitudinally and uniformly staggered from the firstfins, so that a plurality of parallel modules adjacent to each other willhave the recesses between adjacent fins closed by the opposite fins toform longitudinally staggered vertical holes for the fluid passage ofthe melted thermoplastic material.
