Abstract: A fluid application device stores seam paste in a reservoir tank 18 and feeds the seam paste to a pressure tank 20 through a feed pump 22. Inside of the pressure tank 20 is maintained under a given air pressure by a pneumatic unit 26, and the seam paste is supplied from the pressure tank 20 to an application nozzle 16 through a supply pipe 24. A level sensor 28 detects fluid level of stored seam paste in the pressure tank 20, and a detection signal is input to a controller 30. The controller 30 controls operation of the feed pump 22 based on the detection signal that is transmitted from the level sensor 28 and also controls a supply amount of the seam paste to the pressure tank 20 to maintain the fluid level in the pressure tank 20 at a fixed level.

Abstract: A belt-like material stably transferring apparatus an absorbing and feeding apparatus for continuously absorbing and feeding the belt-like material by use of a difference in air pressure. The absorbing and feeding apparatus comprises a reserving chamber for absorbing and feeding the belt-like material to be reserved therein, and a pressure detecting chamber connected to the reserving chamber through a slit. The reserving chamber has an opening portion for feeding the belt-like material, and blowers and are connected at a position, which is opposite to the opening portion. The pressure of the pressure detecting chamber is changed in accordance with the change of the pressure in the reserving chamber connected to the pressure detecting chamber through the slit. The pressure of the reserving chamber is changed in accordance with the amount of absorbing and feeding the belt-like material absorbed and fed to the reserving chamber.
