11.6.10 Exchanging the Rubber-Metal Vibration Damper
For this step, the cutter is lifted out of the machine.
WARNING
Wear thick protective gloves. 11
CAUTION
Before you exchange the rubber-metal vibration dampers, the disassembled pneumatic cutter
must be screwed to the mounting plate (Item no.: Section 11.3) before removing any part.
If this prefabricated plate is not available, the rubber-metal vibration dampers have to be ex-
changed at the Siemens factory because, if this plate is not used, it is impossible to reassemble
the blades/tape deflector without distortion.
The cutter must be completely assembled before it is removed from the plate (all screws tightened:
see Fig. 11.4.2).
Tighten the screws to the correct torque -> see Table, Fig. 11.4.2. 11
NOTE:
In the case of a problem, all 4 rubber-metal vibration dampers are always exchanged. 11
à Turn the machine and then the compessed air ON.
à Disconnect the movable component changeover table from the machine and move it out of the
machine.
à Turn the machine OFF, disconnect the machine from the mains and turn off the flow of com-
pressed air at the compressed air unit. Actuate the needle valve on the compressed air unit to
bleed the compressed air lines (see DANGER text in Section 11.1).
à Remove the pneumatic cutter, as described in Section 11.6.1.1.
à Note the CAUTION text above.
à Before any further disassembly, place the dismantled cutter so that the retaining brackets (LH
and RH) are on the prefabricated mounting plate (Item no.: see Section 11.3) and screw it tight
with four M6 socket hex head cap screws.
à Mark the mounting position on the stationary blade (left end must remain on the left).
à Remove the stationary blade, as described in Section 11.6.2.

à Remove the cover plate holder (incl. cover plate), the tape deflector holder incl. tape deflector
and the two holddowns incl. the spacers, as described in Section 11.6.3.
– The version 03 holddowns match the version 04 cutters (= with tape deflector).
– Blades and spacers are attuned (= match).
à Loosen the screws fastening the 2 rubber-metal vibration dampers on the left and right (one
M4 socket hex head cap screw on each: see Fig. 11.4.3 -> 9).
à Lift the cutter off the rubber-metal vibration dampers on the cutter holders.
à Working from the bottom, loosen the srews fastening all 4 rubber-metal vibration dampers to
the cutter holder (one M4 socket hex screw each: see Fig. 11.4.3 -> 9).
à Make certain that disks and spring washers previously removed are placed back under the vi-
bration dampers (see Fig. 11.4.3 -> 12 and Fig. 11.4.2 -> 18).
à Place the 4 new rubber-metal vibration dampers (Item no.: see Section 11.2) on the retaining
brackets and, working from the bottom of the brackets, screw the dampers tight.
à Working from above, place the cutter onto the vibration dampers and screw it tight to them (Fig.
11.4.3 -> 9). Pay attention to the length of the screws (= 20 mm).
à Assemble the cutter in the manner described in Section 11.6.3.2.
à Dismantle the cutter from the mounting plate.
à Mount the cutter in the machine, as described in Section 11.6.1.2.
à Install the empty-tape duct assembly and check the entire length of the gap between the lead-
ing edge of the tape deflector and the “empty-tape baffle, inside", as described in Section
11.6.8.
à Perform the appropriate “Final Steps” (see Section 11.6.11).

11.6.11 Final Steps
CAUTION
Tighten the screws to the correct torque -> see Table, Fig. 11.4.2. 11
à Make certain that each of the cables running out of the left and right of the control board box
is again fastened to the fixing pedestal with cable tie.
The strain on the cables / plug-and-socket connections must be relieved (Fig. 11.6.6 -> 8).
à Check the gap between the leading edge of the tape deflector and the "empty-tape baffle, in-
side", as described in Section 11.6.8.
à Where applicable, mount the tape chute into the machine.
à From below mount the stop buffer assembly on the machine frame (two M8 socket hex head
cap screws on left and right).
à If the nozzle changer is removed, stop the nozzle changer over the installation position and and
make the electrical and pneumatic connections.
à Mount the nozzle changer.
à Turn the compressed air back on at the main switch on the compressed air unit.
à Move the changeover table back into the machine and connect it.
