  • the rejuvenation of the second portion of the board takes place in that the board is cut (preferably by punching) prior to forming such that two outer edges of the board extending along the direction of extent, which face each other transversely to the direction of extent, face each other in the transition area run and in the second section transverse to the direction of extension have a smaller distance from each other than in the first section.
  • through holes are formed on the board for the later mounting of the barrier.
