  • Device for lubricating and cooling molds, in particular forging dies and tools in metal forming
    Patent number: 7290426
    Abstract: A device which is designed as a spray head and is intended for lubricating and cooling molds, in particular forging dies and tools in metal forming, is described, in which device the feed passages for coolant, compressed air and lubricant are accommodated in a common compact housing but are designed to run separately from one another, and in which spray nozzles are in each case assigned to these separate flow passages, these spray nozzles being specifically designed for spraying the lubricant and the coolant, respectively. By means of this measure, the spraying operation can be designed in an optimum manner and it becomes possible to keep the lubricant and coolant consumption low.

  • Process and device for spraying a moving fibrous web
    Patent number: 6444090
    Abstract: Process and apparatus for spraying a moving fibrous web with at least one jet. The process includes feeding a controlled volume flow of a spray agent to the at least one jet through at least one pulsing valve, and damping and reducing pulses occurring in the controlled volume flow of the spray agent. The apparatus includes at least one jet arranged to be fed with a controlled volume flow of a spray agent, at least one pulsing valve which feeds the controlled volume flow of the spray agent to said at least one jet, and at least one pulse damper arranged to damp or reduce pulses occurring in the controlled volume flow of the spray agent.
