Abstract

In a system (1, 101, 201) for spraying hot-melt adhesive onto glued surfaces comprising a melter (61) to heat hot-melt adhesive, an air compressor (60), a power and control system (63) and a gun (10). The gun (10) is connected to the melter (61) by a pipe (53) with screw connectors (54, 55), through which a hot-melt adhesive being heated flows, and the air compressor (60) by an air pipe (56) with screw connectors (57, 58) through which a pressurized compressed air flows. The gun (10) has a nozzle (20) with a hot-melt adhesive outlet or orifice (21) and a compressed air outlet (23). The pipe (53) through which flows the hot-melt adhesive having a viscosity between 2500 mPa*s and 7000 mPa*s and a temperature between 120°C and 200°C, and a density between 0,8 kg/dcm³ and 1,4 kg/dcm³, and the air pipe (56) are fitted in an insulating layer of a hose (50), and whereas the throughput of the pipe (53) through which the hot-melt adhesive being heated flows is between 0,5 kg/h and 1,5 kg/h, while the air pipe (56) has a throughput between 0,1 m³/min and 0,6 m³/min.
