A fully automatic, recipe-driven hot melt applicator for roll-fed labeling, the B & H glue extrusion system produces void-free glue patterns while eliminating vacuum drum re-padding. Using a controlled combination of pressure and temperature, the PLC-driven system applies an extruded film of hot melt adhesive to preprogrammed locations on labels through a vertical pattern nozzle, regardless of fluctuations in production speed. The unit controls glue laydown weights within +/-10% of the programmed target weight; it controls the glue pattern placement on the label within +/-0.01 inch and the glue temperature within +/-1°F.
