  • This is possible due to the individually adapted to the individual workpiece size transverse displacement of the workpieces 10 by the Versetzstation 40, so that as shown in the figures, individual workpieces with different sizes in the flow can be edited without clock loss with 1 piece.
  • the workpieces can be processed in any order both longitudinally and transversely, since the driving rails 30 are highly controllable or retractable as needed.
  • the device according to the invention in particular plate-shaped workpieces 10 by a two-pass through the device according to the invention angle and dimensionally can be edited on the edges, for example, to a finished door element with umgeleimten edges.
  • the transport device transverse to the direction of movement and over the entire width of the transport device extending longitudinal elements to rest for the workpieces 10, wherein the longitudinal elements extend over the entire width of the transport device such that they on the transport chain 53 as are also stored on the conveyor chain 54.
  • the workpieces 10 can be arranged on the longitudinal elements both during the processing of the first side 11 and during the processing of the second side 12, wherein the workpieces 10 by the transfer station 40 on the longitudinal elements of the transport device can be moved.
  • These longitudinal elements can in turn be raised, so that thereby give the follower stop assemblies 30, which can be controlled with respect to the respective workpiece size.
  • the length dimension of the workpieces is usually in about 250 to 2400 mm, with workpieces having a length less than 1200 mm according to Fig. 4 be shifted from right to left. However, if the workpieces are greater than 1200 mm, they are moved from left to right and then again left to the second stop position. This arrangement is particularly useful in that the displacement times are kept as low as possible and the width of the device according to the invention is minimized.
