Definitions

  • the invention relates to a floating element for guiding sheets in a Sheet processing machine, especially in a printing press.
  • Floating elements are known, which are in brackets or guides Printing machine between printing units or in the area of a sheet delivery are used to guide the sheet particularly at critical points improve.
  • Floating elements are used in different training floating arch support on an air cushion, for arch lifting, Sheet smoothing, for sheet braking, by suction to the floating pull Sheet transport used. They consist of a fixed in the machine arranged housing with arranged on the outside leading the sheet Air nozzles and one to the compressed air system and / or to the suction air system of the Machine connectable interior.
  • the necessary use of such Floating elements is largely dependent on the nature of the substrate, but also dependent on operating conditions. Floating elements are therefore ever according to the type of order to be processed for different tasks different positions needed. Floating elements are often not required annoying in the way.
  • the air supply is carried out by external control Compressed air or with suction air.
  • Blown air-supplied sheet guiding elements are known from DE 42 42 730 A1, which are designed as exchangeable cassettes. This makes it possible to use one specific point on the machine, the sheet guiding element against another with different nozzle openings.
  • a floating element of the type mentioned can be used as a compact component in different areas shape.
  • This task is accomplished by training according to the characteristics of the Claim 1 solved.
  • a floating element with the inventive features can be added to any Place of a sheet-processing machine, in particular a printing machine, are used, namely for bow stretching, bow braking, Accelerating or guiding sheets, especially when moving, unrolling or hold.
  • An embodiment with a housing that is as flat as possible is preferred Sandwich construction, so that the accommodation of a floating element with the Features of the invention is also possible in confined spaces. Possibly can floating elements made of air-guiding housing parts and others Air source receiving housing parts are composed.
  • a further development of the invention provides that several air leading Housing parts and possibly also several air sources receiving housing parts are interconnected in such a way that Complementary coupling elements automatically in the manner of a plug-in coupling Make connections between the housing parts.
  • Figure 1 shows a Side view of the levitation element according to the invention.
  • This consists of a rod-shaped sheet metal housing 1, which consists of a Cross-section approximately U-shaped lower part (1a) and one of its top tight final upper part (1b), this upper part at intervals from each other and in series one behind the other blowing nozzles 2. Top and the lower part of the sheet metal housing are airtight on overlapping edges connected with each other.
  • the elongated housing 1 is at one end an ejector 3 coupled to the air-guiding interior of the housing 1 connected is.
  • the ejector 3 is correspondingly connected via a compressed air line 4 dimensioned compressed air source or, if necessary, also with an under correspondingly high pre-tensioning compressed air system of a machine connected.
