Gas hose 46B to vacuum subassembly 24 air mass flow, and by air hose 46C control pump 32 motor 38, air hose 46D
Air-source 16 is connected to the solenoid component 40 of distribution system 34, bypasses air shut-off valve 17, the control pressure of solenoid component 40
Flowing of the contracting air to distribution module 44, to start distribution module 44 in open position, to distribute liquid adhesive and closing
Position, thus prevent liquid adhesive be assigned, controller 18 is communicated with all parts of system 10, as air shut-off valve 17,
Melt system 30, pump 32 and/or distribution system 34 and its various parts, for the operation of control system 10, cold section 12 of component
It can run at room temperature, without heated, container 20 can be the hopper for accommodating a large amount of solid binder particles, suitably
Adhesive may include such as thermoplastic polymer adhesive, such as ethylene-vinyl acetate, and feeder assembly 22 connects container 20
It is connected to hot part 14, for solid binder particles to be transmitted to hot part 14 from container 20, component feeding 22 includes vacuum group
Part 24 and feeding hose 26, vacuum subassembly 24 are located in container 20, and the compressed air from air-source 16 is transported to vacuum group
