  • the feed member 25 consists of a side or staggered suction disc 26 and an axially parallel directed suction fingers 27. Both capture the blank 10.
  • a cross-facing in the conveying direction Edge area of the blank 10 is in contact with the suction finger 27.
  • a lateral edge area of the blank 10 is by the rotating suction disc 26 held.
  • the blank 10 is called Partially cylindrical hollow body in the region of the movement path of the Folding mandrels 24 kept ready and taken by them one after the other.
  • the cutting unit 14 or the folding turret thus formed 23 with the assigned organs corresponds in structure and in the Operation of the unit according to DE 196 44 079.3.
  • the cutting unit 14 works in such a way that the material web 11 through the preferred rollers 12, 13 and as a deflection roller serving cutter roller 16 on the circumference of the conveyor roller 19th is created.
  • the operation of the cutting unit 15 is like this formed that a front end portion of the web 11th already bears against the circumference of the conveyor roller 19 and on this is held by suction bores 20 or the vacuum, if the separating cut for the production of the blank 10 performed becomes.
  • the conveyor speeds are coordinated so that the web of material 11 slip under the circumference of the Conveyor rollers 19 abuts. This is therefore with a greater peripheral speed driven as the conveying movement of the material web 11. After cutting off the blank 10, this is on the peripheral speed of the conveyor roller 19 accelerates.
