Definitions

  • the invention relates to a device for applying a coating medium on at least a partial surface of an elongated and transported in its longitudinal direction workpiece consisting of a loadable with vacuum coating chamber with one in the inlet and the outlet side of the same formed and adapted to the cross section of the workpiece Opening and from a located in the coating head and can be acted upon with the coating medium slot.
  • a device for applying a coating medium on at least a partial surface of an elongated and transported in its longitudinal direction workpiece consisting of a loadable with vacuum coating chamber with one in the inlet and the outlet side of the same formed and adapted to the cross section of the workpiece Opening and from a located in the coating head and can be acted upon with the coating medium slot.
  • a device is off DE 4 337 438 known.
  • the coating media used are pumpable and filterable, liquid liquids such as pigment solutions, paints, lacquers, primers and impregnating agents. These coating media are applied in a box-like coating chamber by an applicator unit mounted in the same, which is designed as a spray or flood frame or slot nozzle, either profile-dependent or profile-independent.
  • the coating chamber has both in its inlet side and in its outlet side wall to an opening which is adapted to the cross section of the workpiece, extends at right angles to the transport direction of the workpiece 2 and may be formed by a replaceable template.
  • this opening is formed slightly larger in its cross section on all sides, so that between the boundary edges of the opening and the workpiece, a circumferential, constant gap is present.
  • air flows from the outside into the coating chamber, entraining excess coating medium, so that the thickness of the applied coating medium is approximately the same over the entire surface or partial surface.
  • a workpiece may have transverse grooves, transverse grooves, holes or blind holes between its ends.
  • the outlet opening so the opening at which the coating medium is already on the workpiece, created in the outlet opening to the workpiece a significantly larger gap through which changes the flow rate and the speed of the sucked outside air.
  • the thickness of the coating medium changes or increases in such areas. For example, this accumulation of the coating medium may result in a non-functional coating associated with cracks and / or color changes.
  • the invention is based on the object to show a device for applying a coating medium on at least a partial surface of an elongated and transported in its longitudinal direction workpiece, wherein the occurring by a reduction in cross-section of the workpiece change the speed and the volume of the air sucked from the outside not Significantly detrimental effect on the thickness and on the quality of the applied coating, without the need for special nozzles and air streams are required with appropriate controls.
  • the air sucked from the outside no longer flows in the cross-section reduced areas in the transport direction of the workpiece, but on the reduced cross-sectional areas, so that even in these areas, the desired coating quality is achieved without additional effort.
  • the air sucked from the outside no longer flows in the cross-section reduced areas in the transport direction of the workpiece, but on the reduced cross-sectional areas, so that even in these areas, the desired coating quality is achieved without additional effort.
  • At the ends of the workpiece no thickening or beading occur. Even in slot and pin areas excess coating medium is sucked in the same way as at the other places. No additional effort is required to achieve these benefits.
  • the device is space-saving, since additional nozzles with lines and controls omitted.
  • a coating chamber 3 which is connected to a vacuum line 4.
  • This coating chamber 3 has an opening 6 both on its inlet-side wall and on its outlet-side wall 5.
  • Both the inlet opening and the outlet opening 6 may be formed in a replaceable template which is inserted into the wall 5.
  • the cross section of the outlet-side opening 6 is adapted to the cross-section of the workpiece 2, but the cross-section of the opening 6 on all sides by a predetermined amount is greater than the cross-section of the workpiece 2.
  • the air sucked in via the gap between the workpiece 2 and the opening 6 does not flow exclusively in the longitudinal direction of the workpiece 2. Rather, when the one end of the groove 7 first reaches the region of the opening 6, sucked air through this groove 7, which also entrains excess coating medium in this area, so that the desired uniform application of the coating medium is achieved here as well.
  • inlet-side wall 5 - as indicated by dashed lines - and arranged there opening 6 to be arranged at an acute angle transversely to the transport direction of the workpiece 2.
