METHOD AND HOT MELT MIX APPLICATOR WITH HEATED HOSE AND APPLICATOR WAND

摘要

A heating system for a hot melt mix applicator hose (22) and dispenser wand (24) comprises a three phase heating element (30) powered by a generator (166) that is a vehicle alternator (194) driven by an internal combustion engine (52) to heat the hose (22), wand (24), and hot mix material within. A controller (46) communicates with a temperature sensor (122) carried by the hose (22) to selectively energize the generator (166) to provide current to the heating element (30) to maintain the desired hot mix material temperature. The heating element comprises three phase heating element wiring (98, 100, 102) wrapped around the hose (22) and wand (24).
