Systems and methods related to dispensing fluid and controlling a dispensing operation. The system includes a fluid dispenser including an inlet and an outlet, the dispenser being operable to start and stop the flow of the fluid from the outlet onto a substrate. The system also includes a fluid supply reservoir adapted to hold the fluid, and having an outlet coupled in fluid communication with the inlet of the fluid dispenser to establish a flow path for the fluid between the fluid supply reservoir and the outlet of the fluid dispenser. The fluid supply reservoir further includes a pneumatic input coupled to an air flow path adapted to receive pressurized air for forcing the fluid from the outlet of the reservoir. An electronic air flow meter device is operatively coupled to the air flow path to produce electrical output signals.

An applicator head for a vacuum coating system includes a manifold shell having opposing shell plates, each including a conduit attachment coupled to a shell aperture. An applicator manifold is affixed to each shell plate. Each applicator manifold includes two coupled manifold plates, with one including a manifold aperture, and each is affixed to the respective shell plate so that each manifold aperture aligns with the respective shell aperture. An applicator channel is formed between the manifold plates of each applicator manifold, and the applicator channel is fluidically coupled to the manifold aperture of each respective applicator manifold. Each applicator channel forms an applicator port at a leading edge of each respective applicator manifold, and each leading edge is configured to be complementary in shape to an edge of a workpiece to be coated. First and second face plates are disposed over the leading edges of the applicator manifolds.

A glue delivery system and method for providing precise application of glue on a substrate. A bead of glue is extruded from a first glue chamber to a leading edge of the substrate. A trailing edge of the substrate is blown off and over to the nozzle to receive a smear of glue from a second glue chamber. A gear pump is controlled by a servo drive that is connected to a servomotor utilizing a gear reducer. The pump regulates the extrusion of the glue onto the substrate that is programmed with empirical data of gear reducer ratio at which the glue flows within a constant speed, torque, current, speed and position of the glue. The empirical data is provided to a programmable logic circuit to achieve a precise pressure related to volume of a glue deposition and speed of the substrate onto which the glue is applied.

The invention relates to a device for producing an adhesive tape (2), comprising a supply unit (5) for supplying a strip-type textile carrier (3) of the adhesive tape (2), and a coating unit (6) for applying an at least lamellar adhesive coating (4) to at least one side of the carrier (3). The invention also relates to an ultrasound unit (9 and 10) and/or a laser unit for producing perforations and/or cut edges in the carrier (3).

An applicator tool positionable within a valve seat bore of a cylinder head for an internal combustion engine. The applicator tool includes a sealing portion extending radially outwardly from a base body of the applicator tool for sealing abutment with the valve seat bore, a wiper portion extending radially outwardly from the base body and narrower in diameter than the sealing portion, and a circumferential groove between the sealing portion and the wiper portion and recessed relative to the wiper portion, wherein the circumferential groove has a groove base which is circumferentially continuous.

A device for coating material with resin and subsequently laying the material saturated with the resin onto a surface, the device comprising a vessel for retaining the resin, the vessel having a slot sized and configured so that the material is passable through the slot after being coated with resin retained in the vessel, and a first and a second roller being arranged on either side of the slot or behind the slot.

Provided are a method and an apparatus for producing a functional film with a coating solution including a material whose performance is deteriorated by oxygen, without performance deterioration. The method for producing a functional film includes a coating step of supplying a coating solution having a dissolved oxygen concentration of 1000 ppm or less to a die coater having a backup roller and applying the coating solution to a flexible support transported in a state where the support is wound around the backup roller by the die coater, in which a reduced pressure chamber which covers a surface of the flexible support is provided on an upstream side of the die coater in a transport direction of the flexible support, and an inert gas is supplied to the reduced pressure chamber and an exhaust amount from the reduced pressure chamber is larger than a supply amount of the inert gas.
