Quick change system for SPRINT Series
1. Quick change system for SPRINT Series
The task of the quick change system is to reduce the machine setup time when
changing operation mode between border frame/cap/tubular. After converting the
machine to the quick change system, accesories which have not been converted
can be connected as customary to the quick change system.
The quick change system is designed solely for machines of the series SPRINT 6.
A conversion can only be carried out for SPRINT 6 and SPRINT 5 machines.
The installation is not possible in case of the following machine
types!
• SPRINT
• SPRINT 2-4
• SPRINT XL
• JAFA-/JNF-Serie
• L-/M-/S-/X-/Y-/Z-Serie

1.2 Preparations
Please read the description of the procedure carefully through. The description
contains information which you have to be aware of before the installation.
Subassembly of the horizontal barrel adjuster
Screw one of the nuts on the clamping
screw.
The end position of the nut should
be approximately 3-4 mm above the
screw head.
Slide one of the guide washers on the
screw. The guides of the washer should
be located on the far side of the head
of the clamping screw.
Carry out the assembly with the second
clamping screw as well.
Fig. 1: Clamping screw with nut and washer
Insert the prepared clamping screw
from the bottom of the inclusion of the
horizontal clamping xture.
Slide the second guide washer above
the clamping xture adaptor from the
top on the clamping screw.
The guides of the washer must be in
the direction of the clamping xture
adaptor.

Screw the second nut on the clamping
screw and tighten slightly.
Run the installation described above
with the second horizontal clamping
xture.
Fig. 3: Clamping xture adaptor (side view)
Attach one of the pre-installed
horizontal clamping xtures with 4
screws and 4 washers on one of the
cleviss, as shown in (Fig. 4).
Thereby tightening the screws only
slightly.

Disassembly, conversion and assembly of the carriage
Fig. 6: Cover, Disassembly
Remove the cover of the pantograph drive for lateral movement.
Remove 2 screws with plastic washers on the top and the 3 screws with plastic
washers on the back of the cover.
Do not loosen in any case the
fastening of the drive belt on the
connection (X)!

Quick change system for SPRINT Series
Disconnect the carriage by removing two fastening screws.
On the bottom of the carriage the connection is xed by 2 locknuts.
The drive belt is now loosened from the carriage and can be moved
without barriers.
Fig. 9: Carriage, Disassembly
Rotate the drive belt carefully until you can reach the rear mounting screws of the
carriage.
Remove the 8 mounting screws incl. the locking washers from the two movable
pilot carriages and remove the carriage.
Fig. 10: Carriage (view from the bottom)
The countersunk screws are inserted with LOCTITE 290 and they
are sitting thightly. Be careful, when removing the screws in
order not to deform or distroy the cross slot.
Disassemble the two clevises by removing the 4 countersunk screws.
The countersunk screws are inserted with the glue LOCTITE 290.
Due to the relatively high effort which is needed to remove the
screws, it may, at the disassembly come to deformity of the screw
heads. Use the new countersunk screws from the package to fasten
the horizontal clamping xture.

Fig. 11: Horizontal clamping xture assembled, carriage (view from above)
Mount the two pre-assembled clevises with the horizontal clamping xture on the
carriage. Observe the mounting direction of the horizontal clamping screw.
Rotate the mounting screws ca. 1 turn in the thread.
Place a drop of Loctite 290 (or equivalent adhesive from another manufacturer)
on the threads of the 4 mounting screws.
Only tighten the two screws securing the individual clevises rmly after both
countersunk head of the screws are sitting in the intended cuts.
Fig. 12: Carriage, assembly
Assemble the carriage with the 8 mounting screws (incl. locking washer) on the
two movable pilot cariages of the pantograph drive for lateral movement.
Secure the connection with the two
screws incl. the washer on the carriage.
Fig. 13: Connection, assembly
On the bottom of the carriage the screw connection is countered by
2 lock nuts.
For securing the connection, screw the two lock nuts from below rmly on the
screws.
ÖSo the transmission of motion of the pantograph drive for lateral
movement is established again.

Using a suitable spanner set the
absorving energy of the system with
which the tubular frame has to be
pushed in the guides on the centring
devices.
Fig. 20: Centring device, force setting
Check the setting by moving back and forth the cylinder arm frame holder
Change and check the settings of the absorving energy until you nd the
appropriate setting.
Centring device Impact
Setting tighter higher effort
Setting looser smaller effort
The setting is right if the cylinder arm frame holder slides into both clevises
evenly under slight pressure.
Slide the cylinder arm frame holder
with the centring devices in the guides
of the two clevises.
Set a parallel distance of 6,0 mm
±0,3 between the carriages of the
pantograph drive and the cylinder arm
frame holder.
Fig. 21: Distance setting
To facilitate the setting of the 6 mm distance a correspondingly thick
gauge can be applied. This can be a metal strip, 2 screws or similar
material of the appropriate strength.
Place the clamping screws of the two
horizontal clamping xtures centered
in the recording of centering devices.

Quick change system for SPRINT Series
Set over the lower nuts of the two
clamping screws the contact pressure
of the two horizontal clamping xture.

countered with the upper nuts of the
two clamping screws.
Fig. 23: Clamping screws, adjustment
Check the setting of the comprehensive force by repeatedly opening and closing
the horizontal clamping xture.
Close the horizontal clamping xture completely.
The horizontal clamping xtures are correctly adjusted when they can be
completely closed with a clear click-sound and not much effort.
Contact pressure Impact
to small no click sound
correct clear click sound
to high effort when closing the clamp too
high, horizontal clamping xture
is very difcult to close.
The basic setting of the quick change system is herewith concluded.
The cylinder arm frame holder can be used now with the quick change system.
Replace the cover of the pantograph drive for lateral movement. 2 screws with
plastic sheaves on the top and the 3 screws with plastic sheaves at the back of the
cover. See (Fig. 6).

slight pressure.
A new adjustment of the clamping screws on the horizontal clamping
xtures is not necessary.
Fig. 31: Pantograph drive, cabinet slot
Please pay attention when inserting the centring devices in the clevis, that the
lower clamping devices of the cap attachment are opened wide enough and that
the threads of the lower clamping devices sit in the two slots of the cabinet on the
pantograph drive for lateral movement.
If you can not position the cap attachment accordingly, the pantograph can move
laterally and brought into position by means of the pantograph control.
