  • the form fingers are pivoted 12.1 with the hooks 24.1 in a pivoting movement about its pivot axis 14 upwards and outwards.
  • the sheath 17 around the respective lower inner edge of the two feet 19, 21, that is, pulled around the lower right inner edge of the base 19 and the lower left inner edge of the base 21.
  • each shaping device 7 is again moved horizontally in the direction of the orthogonal to the conveying direction 3 of the pallet 2 aligned side of the pallet 2. Since the two form fingers 12.1 of a forming device 7 are longer than the four form fingers 12 of this forming device 7 and thus protrude with respect to the forming fingers 12 in the direction of the pallet 2, the forming fingers 12.1.
  • the pallet 2 facing surface of the hook 24.1 as a result of the horizontal movement with the base 23 and the outside of the located in the travel base 19, 20, 21 in contact.
  • the pallet 2 facing surface of each hook 24.1 as previously with respect to the Fig. 5 and 6 described, preferably coated with the non-stick and / or heat-resistant material 27.
  • the sheath 17 at the two sides to be formed which are in the illustrated embodiment, the short end faces of the pallet 2, when pulling the shroud portion 18 to the outside and / or when shifting the shroud portion 18 upward additionally be fixed by a displaceable in the direction of the pallet 2, pin-shaped fixing 25.
  • the fixing element 25 By means of the fixing element 25, the sheath 17 is pressed against the pallet 2. This frontal fixation avoids unwanted crescent formation.
  • the middle chain track 1 consists of two mutually parallel spaced chains.
  • the fixing element 25 is located between the two chains of the middle chain track 1.
  • the fixing element 25 acts in the middle of the pallet 2 approximately at the level of the base 23 or slightly deeper.
  • the fixing member 25 is in the illustrated embodiment by a pivoting movement of his in Fig. 1 illustrated rest position in which it does not protrude from the plane of the chain conveyor, moved to its fixing position.
  • the pivot axis and the associated drive of the fixing element 25 may be part of the chain conveyor. But it is also quite possible that the pivot axis and the associated drive of the fixing element 25 are part of the molding device 7.
  • the fixing element 25 can be located laterally at a small distance from the middle chain track 1. Then it does not act exactly on the center of the pallet 2, provided that the pivoting plane of the fixing element 25 is parallel to the axis of the chain track 1 and the conveying direction 3. However, if the pivoting plane of the fixing element 25 is not parallel to the axis of the chain track 1 and the conveying direction 3, a contact in the middle of the pallet 2 is also possible in this case. Regardless of the orientation of the pivoting plane of the fixing element 25, the fixing element 25 acts approximately at the level of the base 23 or slightly deeper on the pallet. 2
  • each side of the middle chain track 1 each have a fixing element 25, so that in this way the casing 17 is pressed against the pallet 2 at two points.
