Abstract
A modular system, for delivering hot melt adhesive materials, comprises a modular metering assembly, having metering stations disposed therein, that is able to be attachably and detachably mounted upon a modular tank assembly. Alternatively, one or more of the metering stations may be disposed externally of the modular metering assembly, and alternatively still further, one or more additional modular metering assemblies may be attachably and detachably connected to the first modular metering assembly. Also disclosed is a closed-loop fluid pressure control system, for independently controlling the pressure of the hot melt adhesive material being conveyed to the metering devices, whereby the working pressures of the hot melt adhesive materials being conveyed to the metering devices can have different working pressures.
