  • Patent number: 5217169
    Abstract: A device for retarding drool from a multi nozzle manifold having a plurality of outlet passageways in fluid communication with a single feed passageway. A drool-retarding member selectively segregates the outlet passageways with respect to fluid communication among the outlet passageways, preventing flow from one outlet passageway into a lower outlet passageway during adhesive cutoff periods. The drool-retarding member is a reciprocating member having an inoperative position in which a plurality of inlet ports to the outlet passageways are sealed, and having a fluid-apply position in which the inlet ports are free to allow fluid communication among the outlet passageways and the feed passageway. In a passive embodiment, the drool-retarding member is a valve that is spring biased to cover the inlet ports. Pressurized adhesive overcomes the bias of the spring when an upstream flow-regulating mechanism is controlled to discontinue adhesive flow.
