- the present invention is the Task based on a filing device like this to improve that one Vacuum control possible when depositing the web sections is and nevertheless the susceptibility to failure when operating the This does not increase the machine, i.e. a safe Fixing the track sections to the contact areas of the Rotor is guaranteed.
- the first rotational position can thus be predetermined once that the time of pressurization coincides with the time when the contact areas touch the track sections of the rotor. It will be the Disadvantage of the known device avoided that too large volume flow through the suction areas into the interior of the Rotors arrives and there the available negative pressure decreases.
- each separate from a vacuum generating device separately controllable rooms can be provided by a respective Print communication opening of a respective contact area of the rotor.
- the size and therefore the Angle of the segment of a circle in which a Negative pressure on the suction areas of the rotor could take place by appropriate control or Non-control of the openings can be achieved.
- a preferred embodiment of the invention stands out characterized in that a mouth opening one with the Suction areas of a respective contact area connected and with the contact areas rotating line means in the area within the circle segment with one or several extending or arranged in the direction of rotation communicating vacuum opening and that between the mouth of the conduit and the vacuum-carrying opening at least one control opening defining actuator is provided, against which the Rotor is rotatable.
- Size of the angle and thus the extent or size of the circle segment, within which one Negative pressurization of the respective suction areas takes place, can be varied by the actuator, namely in that the at least one control opening in the Actuator the vacuum-carrying opening quasi in Extended or shortened circumferential direction.
- the negative pressure opening of one compared to a machine frame in the operation of the stationary part is formed. In this way, it can be repeated mentioned first rotary position exactly defined compared to the Arrange the conveyor level of the flat material web sections. Further can be used for print communication between the negative pressure opening and a negative pressure generating device any necessarily flexible pipe means are used.
- the stationary part mentioned above can form a hub, through which there is a drive train for the rotor extends.
- the negative pressure room creates one sufficient suction capacity.
- the sealing surface is not necessarily flat needs to be trained - it would also be a cone shape conceivable -, it proves to be advantageous if that Actuator disk-shaped or flange-shaped and opposite the negative pressure opening around the Rotation axis is rotatable. So it's not about a linearly movable slide or slide element but the actuator is about the same axis as the rotor preferably with regard to the vacuum-carrying opening limited rotation.
- the actuator is a further development of the invention advantageously limited by a stop element rotatable.
- this inventive concept is the stop element of one protruding over the sealing surface into a recess of the Actuator engaging projection formed.
- the protrusion Limited according to an even broader inventive concept the protrusion the negative pressure opening in One-sided circumferential direction and acts as sealing cams formed in a control opening of the actuator.
- the Projection thus also serves as a stop element and on the other hand as the first rotational position independent of means defining the current position of the actuator.
- Actuator opposite the vacuum-carrying opening motorized, pneumatic or hydraulic, or in other Is driven rotatable can do this on its outer periphery coupling means, for example in the form of a Teeth, a push rod joint or the like. include. It would be but also possible that a meshing with a pinion Internal toothing on a suitable section of the actuator however, radially outside of the drive train for the rotor is provided.

With these The gripper arms 8 pass through the rotor 4 at a receiving station of the flat material web sections in succession be fed. When passing through the receiving station engages under the rotor 4 with its gripping arms 8 respective track section and swings it Track section from the receiving station and spends it in the storage station already mentioned.
- the gripping arms 8 of the rotor 4 are strip-shaped Hollow body formed. As indicated in Figure 4 is shown, comprise the gripping arms in one Contact area 10, with which they can be handled against Flat material web sections can be created, suction areas 12, those within a circle segment area 14 (see FIG. 6) between a first rotational position 16 and a second Rotary position 18 of a respective gripper arm 8 with negative pressure are acted upon.
- the gripping arms 8 are in one to the face and in the radial Open in the respective mold recess 20 in the Rotor disk 6 used and by means of an axial cover 22 and an axial securing means 24 both in axial as well as in the radial direction against loosening on the rotor disk 6 secured.
- the lid 22 is in turn with the Screwed rotor disc 6, which is shown by position 26 is.
- Each gripping arm 8 comprises an axial opening 28 which within the mold recess 20 with an axial opening 30 is aligned in the rotor disk 6.
- the axial opening 30 forms a mouth opening 32 of the rotor 4.
- the hollow gripping arm 8 forms a conduit 34 between the mouth opening 32 and the suction openings 12 of a respective contact area 10th
- the rotor 4 with its rotor disk 6 is opposite one stationary part 36, which forms a hub 38 (FIG. 3) an axis of rotation 40 rotating via a drive shaft 42 driven drivable. Between the rotor disc 6 and the hub 38 is an actuator 44 to be described in more detail Individual is shown in Figure 5, arranged.
- the hub 38 has, as can be seen from FIGS. 1 and 3 is one concentric to the direction of rotation
- Rotation axis 40 extends space 46, which over a Means 47 forming suction channel (FIG. 2, not in FIG. 3) shown) with a negative pressure, not shown generating device is connectable.
- the room 46 is in Form a deep recess in the part forming the hub 38 36 incorporated. This deep recess is to that Actuator 44 through a vacuum-carrying opening 47 limited.
- the surrounding the vacuum-carrying opening 47 axial areas of part 36 form a sealing surface 48, against which the axial side of the actuator 44 in Is essentially sealed. Stand from the sealing surface 48 Protrusions 50 and 52, the protrusion 50 extending the space 46 limited in the circumferential direction.
- the protrusion 52 is of that other circumferential end of the space 46 in the circumferential direction spaced.
- the projections 50, 52 engage in recesses 54, 56 in the Actuator 44 a ( Figures 5, 6).
- One side each 58, 60 of the projections 50, 52 form a stop element and limit the rotatability of the actuator 44 in Clockwise direction of Figure 6.
- the other side 62 of the Projection 52 forms a stop element for the rotation counterclockwise.
- the actuator 44 disc-shaped and has a flange portion 64 with which it is in a central opening of the hub 38 hineinerstreckt.
- a Rolling bearing 66 is provided, which is rotatably radially inside on the drive shaft 42 clamped collar sleeve 68 which connected in a rotationally fixed manner to the rotor disk 6 by means of screws 70 is.
