Abstract:
A system for supplying heated material and applying it to a substrate, wherein the system includes a hot melt unit which heats and supplies material from a material reservoir through at least one material output line, each said material output line being connected to a device manifold, each said device manifold being connected to a material application device, each said device manifold having a material flow passage therethrough; each said device manifold including a flow restricting orifice disposed in said material flow passage and a pressure transducer disposed between said orifice and said material application device, said heated material flowing from said material output line and through said orifice of said device manifold past said pressure transducer and into said material application device, said transducer having a sensing face exposed to the flow of said heated material for sensing the pressure of the heated material in said material flow passage and producing an output indicative of the pressure therein, said heated material being applied by said material application device to said substrate.
