Abstract
The invention pertains to a system for dispensing tacky thermoplastic material such as butyl, and the like, and includes encasing a strip of the tacky material within a thin, non-tacky thermoplastic film capable of fluxing into the material at elevated temperatures wherein the material may be wound upon a spool for transportation and handling, and the material is fed from a spool into mixing and heating apparatus, preferably in the form of an extrusion gun, for application where desired as a bead.
