  • the lower edge of the elevator 5 is released from the rail 72 in that the rail 72 is pivoted or rotated by a motor or the front edge of the elevator 5 is lifted manually from the rail 72.
  • the guard 70 which in turn is pivotably mounted and preferably carries a guide roller 66 at the end, is pivoted manually or by a motor so that an access opening results through which the elevator 5 can be fed to the means for fixing the elevator 5.
  • the guard 70 is swiveled back into its starting position manually or by a motor, so that the guide roller 66 contacts the elevator 5 and thus the elevator 5 on its way is guided to the clamping gap formed between the clamping jaw 22 and the impact 24.
  • the elevator 5 is preferably fed by the action of gravity or, alternatively, driven by a motor or manually.
  • the transport cylinder 3 is further rotated counter-clockwise by a motor and the elevator 5 is pressed onto the outer surface of the transport cylinder 3 in the area of influence of the pressure roller 60 until the rear edge of the elevator 5 reaches the clamping gap formed between the clamping jaw 47 and the impact 48.
  • the tensioning shaft 50 is rotated and the clamping gap is thus closed.
  • the pressure roller 60 is then pivoted away. If the elevator 5 is to be removed from the transport cylinder 3 again, the pressure roller 60 remains pivoted away from the transport cylinder 3.
  • Either the front edge or the rear edge of the elevator 5 is released by the transport cylinder 3 and the transport cylinder 3 then rotates so that the elevator 5 is conveyed again in the direction of the store 72. Finally, the edge of the elevator 5 that was still fixed up to that point is released.
  • the arrangement of an elevator 5 on the stripping cylinder 4 is comparable to the arrangement of an elevator 5 on the transport cylinder 3, so that reference is preferably made to this unless differences are expressly described. To arrange an elevator 5 on the stripping cylinder 4, the stripping cylinder 4 is first rotated into a receiving position provided for receiving the elevator 5.
  • the stripping cylinder 4 can be rotated with the aid of an individual drive assigned to it or via a gear train which drives the stripping cylinder 4 with other cylinders and which is driven by a main drive.
  • the stripping cylinder 4 is preferably driven by a single drive, whereas the transport cylinder 3 is driven by a gear train that connects the transport cylinder 3 with other cylinders and into which a main drive drives.
  • the means for fixing the rear edge of the exchangeable elevator 5 are at least approximately opposite the storage 73.
  • the elevator 5 to be fed stands with its lower edge (which corresponds to the rear edge in the fixed state on the stripping cylinder 4) on a memory 73 comprising retaining pins.
  • the retaining pins are designed as positioning means in the form of positioning pins which are provided with positioning recesses in the elevator 5 correspond.
  • the positioning recesses in the elevator 5 are the positioning pins opposite and the elevator 5 is pre-aligned by the assignment of the positioning recesses to the positioning pins.
  • the lower edge of the elevator 5 is released from the retaining pins by pulling in the retaining pins or manually lifting the rear edge off the retaining pins.
  • the pivotably mounted guard 71 which preferably carries a guide roller 67 at the end, is pivoted manually or by a motor, so that an access opening results through which the elevator 5 can be fed to the means for fixing the elevator 5.
  • the guard 71 is swiveled back into its starting position manually or by a motor, so that the guide roller 67 contacts the elevator 5 and thus the elevator 5 on its way is guided to the clamping gap formed between the clamping jaw 22 and the impact 24.
  • the elevator 5 is preferably fed by the action of gravity or, alternatively, driven by a motor or manually.
  • the pneumatic muscle 25 is relaxed and the rear edge of the elevator 5 is thus fixed between the clamping jaw 22 and the cuff 24.
  • the stripping cylinder 4 is then rotated clockwise by a motor.
  • the linear drive 65 is activated.
  • the linear drive 65 pivots the pressure lever 63 until the pressure roller 61 rests against the elevator 5 and presses it against the outer surface of the stripping cylinder 4.
  • the stripping cylinder 4 is then rotated further by a motor in the clockwise direction and, in the area of influence of the pressure roller 61, the elevator 5 is pressed onto the outer surface of the stripping cylinder 4 until the front edge of the elevator 5 reaches the clamping gap formed between the clamping jaw 47 and the impact 48.
  • the tensioning shaft 50 is rotated and the clamping gap is thus closed.
  • the pressure roller 61 is then pivoted away. If the elevator 5 is to be removed from the stripping cylinder 4 again, the pressure roller 61 remains pivoted away from the stripping cylinder 4.
  • Tangent point transport cylinder and upstream sheet transport cylinder B Tangent point of transport cylinder and stripping cylinder C.
