  • the suction openings 6a are thus connected to the ambient atmosphere via the passage 23 and the ventilation recess 21.
  • the kidney-shaped opening 20 is located outside the opening 18 and is therefore not connected to the vacuum source 2.
  • a significant advantage of the rotary slide valve 1 is seen in the fact that the vacuum source 2 does not suck into space, but is closed according to FIG. 8 by the overlap of the opening 18 by the sliding body 12.
  • the suction cups 6 are thus ventilated at a freely selectable point in time which is dependent on the position of the control disk 22 relative to the sliding body 12. Since, as mentioned, the control disc 22 is adjustable in the barrel, the ejection behavior, respectively. the time at which the sheets 38 are dropped onto the collecting chain 29 is optimized and the running speed is thus increased. In principle, this is also possible with the rotary slide valve 51 shown in FIGS. 9 to 12, which is explained in more detail below.
