  • Such devices are made US 2 400 315 . US 3 516 388 . EP 0 520 324 . DE 1 796 280 or EP 1 044 725 known.
  • Such known devices are devices in industrial plants, with which, for example, on a surface of a workpiece, in particular a thermoforming board, an oil film or a layer of adjacent oil droplets is applied. In this way, the "slip" between the punch, the drawing ring and the hold of a deep drawing press can be adjusted.
  • electronically controlled spray valves are used to apply the oil film to the transported substrate, with which the order quantity per surface or the desired application geometry can be precisely adjusted. Because a faulty thickness of the applied oil film can adversely affect the press result. This can lead to wrinkles or optical quality defects on the finished product.

  • the narrow front regions forming constrictions of opposing spray chambers are offset in the transport direction against each other.
  • successive conveying elements for the substrates offset on different sides of the transport plane to each other so that, for example, before application of the liquid application agent on the inlet side, the substrates rest on the inlet side conveyor belt and after application of the applicator on the outlet side, the substrates are transported hanging, being held magnetically, for example, on the outlet side conveyor belt.
