ABSTRACT:
An electrically heated hose for simultaneously heating and feeding melted adhesive and pressurized air to an adhesive spraying head includes a tubular central flexible plastic core for feeding the adhesive therethrough, a resistance heating type helically wrapped around the core with adjacent turns spaced from each other and an outer layer of thermal insulation surrounding the tape and core so that a helically-shaped air passage is formed between adjacent spaced helical turns of the heating tape, the inner wall of the outer layer and the outer wall of the core. A pressurized air admitting tube is connected to one end of the helical passage and a pressurized air discharge tube is provided at the opposite end thereof for supplying the pressurized air in a preheated condition to the spraying head for atomization of the melted adhesive.
