  • Patent number: 6752323
    Abstract: A hot melt high temperature material application system with application device pressure monitoring and heated recirculating manifold uses high temperature pressure transducers with each application device such as spray guns to monitor hot melt material application. A material supply line fitting has a calibrated orifice at the interface with a device manifold associated with each application device. In another embodiment, the calibrated orifice is located in a fluid passageway of the device manifold. The calibrated orifice corresponds in size to the opening of a nozzle of the application device. Heated recirculating manifolds are combined with hot melt material supply systems to provide uniform pressure to multiple application devices, and to recirculate material back through the supply system. Each recirculating manifold includes a heater, pressure regulator, and a recirculation path. The manifolds may be directly or remotely connected to one or more hot melt material supply systems.

  • Publication number: 20020047051
    Abstract: A system and related methods for configuring and monitoring a spraying application system for installation and use at a site that is remotely located from the spraying system manufacturing site. The system provides a configuration module that allows a customer or purchaser to configure a system electronically based on the customer's spraying needs. The selected configuration may further be linked to a pricing and inventory database module to allow the customer to order the system components, and obtain price and delivery schedules. In one embodiment, the configuration module is available to the customer via a secure web site over the Internet provided by a server accessed from a computer such as a personal computer at the customer's site. The system also provides a remote access module that provides spraying system operation and parametric information to be monitored at the manufacturing site to determine how the spraying system is operating and whether repair or maintenance should be initiated.
