The glue blender, installed on a metal supporting structure, consists of a suitable sized drum, a top door for manually loading the material, and a bottom door through which the material is discharged. The mixing tools inside the drum are mounted on a shaft which is operated by a gear motor. Pneumatic nozzles spray the glue mixture onto the material. A small graduated tank containing the glue mixture, is situated at the top of the assembly. The glue mixture flows at a variable rate into the blender by means of a manual valve. The machine comes complete with an electric control panel. The mixing time of the shaft may be set using the timer.
