Abstract
Apparatus for intermittently dispensing substantially constant cross sectional thickness beads of molten hot melt material comprising a service block connected to a pressurized source of molten hot melt material, a dispensing gun module, and a return module. Both the dispensing gun module and the return module are mounted upon the service block, the connection being such that the inputs to both modules are received from the service block. Both the dispensing gun module and the return module have valve elements therein operable to open flow through the dispensing gun module and the return module alternatively so that the pressure of adhesive supplied to the dispensing gun module remains constant as hot melt material is dispensed from the dispensing gun module intermittently.
