Definitions

  • the invention relates to a machine for one-sided or two-sided Applying a liquid or pasty application medium by means at least one commissioned work on the surface of a running Material web, in particular of paper or cardboard; at the Commissioned the application medium from a dispensing opening arrangement, in particular slot nozzle, directly or through mediation at least a guide surface, in the form of a gravitational or / and under the influence of further forces towards a running underground moving curtain or veil, with direct order of the running surface is the surface of the material web and at indirect Order the running underground the surface of a Transmission element, preferably a transfer roller, which is then transfers the application medium to the surface of the web; the machine being assigned to the commissioned work or the one Dispensing opening arrangement having dispensing part of the commissioned work a medium catcher, possibly a drip pan or gutter, for collecting from the dispensing opening assembly discharged application medium in connection with the start or / and completing the order and / or in Intercepting business interruption phases.
  • the medium catcher In order to ensure a good, high Quality requirements of sufficient order result are subject to the various components of the addressed machine various requirements, including the medium catcher.
  • the medium catcher In terms of that the curtain or veil is not too high, that is, the discharge port arrangement is not too high above the running underground, the medium catcher should be in particular in Height direction be made comparatively compact.
  • a proper discharge of the collected medium by the Ensuring catcher, especially in high-viscosity media or / and very wide machines can be difficult and according to conventional usual approaches possibly only at the cost of a large Curtain height is possible.
  • a second aspect of the invention further the task, the curtain or veil by a suitable embellished edge to interrupt the application or to release the order, so that so far a undefined loading of the current underground, in particular the running material web, with application medium is avoided. That's the way it works in conventional medium catchers in the form of across the Material web extending trays or gutters (so-called “starting gutter”) come to that the curtain by adhesion and Oberschreibs bine in the manner of the well-known "teapot effect" on runs off a wall of the starting chute and from this undefined on the Subsurface drips. Such a run down of order medium Area sections of the medium catcher should be avoided.
