Format length also the longitudinal register in the same direction and by the same amount according to the registration marks adjusted. Corrections with respect to the coincident setting of the registration marks 35 a and 36 a cause the same correction in the main preferred device and in the longitudinal register of the perforating device.

There are two additional probes for correcting the incorrect fit

125 and 126 belonging to the perforating device, one of which is a probe head 125 on one of the registration marks 35 ″, 36 a of the paper web 1 and the other probe head

126 are directed to a marking 127 assigned to the phase position of the perforation knife 27. Both Probe heads are via further control lines 128, 129, 130 via a second electronic control device 131 connected to the servomotor 109 of the longitudinal register adjustment device. In this second control device 131 is the target / actual comparison between the registration mark 35 λ or 36 ″ and the position the marking 127 assigned to the perforation knife 27. If the two are not completely identical the paper web 1 carrying the registration mark is readjusted by the longitudinal register adjustment device 108 and thus the matching position between the registration mark and the perforation 28 again manufactured.

According to the embodiment of FIG. 3, the probe head 126 is above the perforating roller which the marking is arranged, the cutting edge of the perforation knife 27 itself making the marking 127 is.

In the embodiment according to FIGS. 4 and 5 is the marking 127 on an end face Adjustment ring! 32 arranged, which can be locked by clamping screws 133.

Instead of the perforating device having a perforating roller, a punch perforating device according to FIG. 7 can be used. This perforating device is denoted generally by 26 α. The perforation knife 27 performs an up and down movement which can be actuated by a toggle lever 134 which swings about the fixed axis 135. The toggle lever is connected to a push rod 136 which carries a freely rotating feeler roller 137 at its free end. The feeler roller runs on the circumference of a cam 138, which either carries the marking 127 itself or has an adjusting ring 132 a with the marking, which is shown in FIG. 7 is shown in dashed lines. The probe head 126 is directed at this marking 127. The cam 138 makes one revolution per format length. The instant of the cut of the perforation knife to produce the cross-line perforation 28 and the instant of the scanning of the marking 127 by the probe head 126 are in phase. The perforation takes place at the moment when the paper web 1 comes to a standstill and is therefore in accordance with the main preferred device 5, which causes the paper web to come to a temporary standstill. The fixed support opposite the perforation knife 27 is analogous to FIG. 1 denoted by 27 α.

In Fig. 1 are further work stations 139 and following the perforating device 26 140 shown, which either produce further cross-line perforations or punchings or impressions can make. Stations 139 and 140, if present, would be in synchronism connected to the perforating device 26, that is to say geared to this. They are controlled indirectly also by the passport marks 35 α and 36 ".
