  • the invention is intended to reduce the risk of breakage of decorative materials when turning.
  • the stated object is achieved by arranging above the magazine a separating and turning drum which receives the at least one suction strip and is rotatable about a horizontal axis, and that the separating and turning drum is followed by a takeover station which takes over the sheet-shaped decorative material and which is opposite to the separator - And turning drum transversely to the axis of rotation along a predetermined path is movable.
  • the top sheet-like decor material Due to the suction effect of the suction of the squeegee, the top sheet-like decor material is sucked in each case. It then adheres to the peripheral surface of the separating and turning drum.
  • the separating and turning drum is moved into such a position that the suction of the squeegee vertically and without spacing or at a small distance to leaf-shaped decorative material stand. After the separating and turning drum is rotated by a certain angle, the recorded sheet-shaped decorative material is turned, ie, the bottom of the stack side is then up.
  • the transfer station is designed so that the respective sheet-shaped decor material can be taken over exactly.
  • the device is designed in its entirety so that the sheet-like decorative materials always have exactly the same position or are aligned before placing on the raw plates, so that they can be fed to the individual raw plates one after the other exactly.
  • the separating and turning drum can be moved in the vertical direction by means of a short-stroke drive and by means of a long-stroke drive.
  • the short-stroke drive By means of the short-stroke drive, the entire separating and turning drum is raised by a relatively small amount, for example by a few millimeters, immediately after receiving the sheet-shaped decorative material, so that during removal of the sheet-shaped decorative material by rotation of the separating and turning drum, then the sheet-like decor material lying in the stack above is not carried away.
  • the long stroke drive the separating and turning drum is also moved to adapt to the changing height of the stack. This is effected by appropriate buttons by the electrical control of the device.
  • a structurally simple solution results when the short-stroke drive and the long stroke drive is formed by a single linear drive, which is controlled according to the required position of the separating and turning drum.
  • a linear drive for example, a spindle drive in question, which is driven by a motor.
  • the linear drive may also be a controlled piston-cylinder unit or an electric cylinder.
  • the magazine is associated with a blow bar so that at least after lifting the separating and turning drum by means of the short-stroke drive a compressed air pulse is generated, which is directed to the stack facing side of the recorded from the separating and turning drum sheet-shaped decorative material.
  • this blow bar must be adjustable in height so that it can be adapted to the height of the stack.
  • the transfer station is equipped with a suction profile, which after the turn of the sheet-shaped decorative material with vacuum to take over the same acted upon.
  • suction bars or suction profiles which can be acted upon by vacuum, is that no mechanical parts are necessary, which would have to be controlled to hold the sheet-like decorative material.
  • the control of the vacuum or the application of vacuum is carried out by conventional valves, which are installed stationary within the device.
  • the transfer station can be lowered and raised, at least in the position that assumes the sheet-like decorative material.
  • the transfer station is lowered so far that the suction profile can take over the sheet-shaped decorative material by the vacuum application and that it adheres to it.
  • the transfer station is raised again.
  • the squeegee of the separating and turning device is retracted by means of a drive in order to protect the sucker.
  • the separating and turning drum is rotatable so that the squeegee is receptive in the final position above the stack.
