  • Guide roller 64 is connected, whose axis of rotation in each case horizontally in the direction of the center axis A shows.
  • the guide rollers 64 follow the said rotational movement B the Course of the guide slot 62. Accordingly, the needles 60th in the downwardly offset angle range 63 over the guide rollers 64 led down. During a rotary movement through this area 63 The needles 60 thus temporarily deviate from the underside of the object 11 vertical back. If the offset angular range 63 so in the area of the cutting plane of a sickle knife or the plane of rotation an ejection star is placed, the needles 60 on the guide rollers 64 and the guide slot 62 there sufficiently vertical moved down to a collision with the rotating sickle knife or ejection star to avoid.
  • the arrangement of needles shown in Figs. 6a and 6b may be used 60 as an alternative to the rotary valve 23 for driving the article 11 to a rotational movement B are used.
  • This alternative drive means can the structure of the device according to the invention and the implementation simplify the process of the invention. Especially is the introduction of a radial slot 52 in the article 11 is not required.
  • By driving the article 11 by means of the arrangement of needles 60 may have a higher positioning accuracy in the Rotational movement B of the article 11 can be achieved because the object 11 both with respect to the direction of rotation B and against this direction is fixed. Also in this type of drive, the article 11 in variable Rotation angles are moved about the center axis A.
