  • the portal 15 engages over the cutting bed, wherein the portal plane is transverse to the transport direction 2.
  • the gantry 15 not only supports the cutting frame 8, 8a of the cutting station during cutting, but also supports two automatically operating cutting frame replacement devices according to the invention, which remove a cutting frame 8, 8a from the cutting station 1 and then re-feed another cutting frame. In this case, the removed cutting frame 8 is transported to a first parking station and then spent the parked in a second parking station cutting frame 8a to the cutting station 1.
  • portalinnen pen each adjacent and extending parallel to a support 16, 17, the cross member 18 superior support columns 19, 19 a arranged.
  • Each support column 19, 19a is in the foot area at a arranged in the cutting station area console element 21 and in the head area in a z. B. located in the cross member area bearing element 22, z. B. in a bearing plate, z. B. rotatable about a vertical axis held.
