- an additional spring element is provided to the Contact between the surfaces of the cam and the control roller Ensure maintenance of a preload.
- Fig. 1 shows the side view of a cylinder configuration according to the invention in Folder with a cylinder assigned to the specimen leading cylinder Cutting cylinder.
- the cutting cylinder 5 comprises two Cutting knife 8 and has two copies on its outer surface to record one after the other, one also speaks in this context of double diameter, while the first exemplary cylinder 6, the Folding knife cylinder, in this configuration four copies on his Circumferential surface 11 can accommodate one behind the other.
- the Copy holding devices on the folding knife cylinder 6 are in the following figures described in more detail.
- the folding knife cylinder 6 works with the one that also holds four copies in this configuration Folding jaw cylinder 7 together, which is equipped with folding jaws 15.
- Grippers 20 on the two transport cylinders 16 and 17 take the cross-folded copies from the circumference of the jaw cylinder 7 and direct they to an upper or a lower delivery 18 or 19.
- Fig. 2 shows the representation of a cutting cylinder with a backdrop Movable copy guide device, which is in the cutting cylinder retracted state.
- the cutting cylinder 5 partially shown here rotates about its axis 21 and is provided on its outer surface 23 with at least one cutting knife 8, which with groove bar on the opposite first specimen leading Cylinder 6, in this example the folding knife cylinder, works together Separate copies from material web 3.
- the cutting knife 8 is in one Cutting knife storage 35 added, which on one side with Recesses 35.1 is provided.
- the cutting knife bearing 35 further comprises two clamping strips made of elastic, resilient material 35.2 and 35.3, with which the cutting knife 8 is held.
- the guide 28 can include a sliding guide 28.1 similar to which a Support 27 - in the vertical direction - is movable.
- On the support 27 is one Copy guide device 24 fixed by means of a fastening 25.
- the top - towards the cutting knife 8 - curved end of the Copy guide device 24 is in the retracted state on the Recess 35.1 of the cutting knife bearing 35.
- the essentially parallel to the normal 29 extending and retracting the Copy guide device 24 is provided by a vertical one Sliding movement of the support 27 on the sliding guide 28.1, for example one Backdrop guidance - generated.
- a lever 30 On a shaft 31, a lever 30 is clamped, the extended lever arm connected to the support 27 by means of a bolt 34 is. Via a control roller 32 on a control cam 36, not shown here rolls (see FIG. 4), a rotation of the Adjustment shaft 31 brought about, which by means of the extended lever arm of the Lever 30 is transmitted as a vertical sliding movement on the support 27.
- the essentially vertical entry and exit movement of the Copy guide device 24 is indicated by the double arrow 26 next to the Copy guide device 24 indicated.
- FIG. 3 the copy guide device 24 explained in FIG. 2 is shown in FIG Cutting cylinder shown extended state.
- Fig. 4 gives a top view of the item guide devices on Cutting cylinder again.
- the control roller 32 can be seen, which rolls on a control cam 36, whereby the movement of the actuating shaft 31 is initiated.
