Installing The Lamination Dummy; Final Assembly - Ottobock 6A20-30 Instrucciones De Uso

6) Position 2 layers of carbon fibre cloth (e.g. 15 cm x 15 cm) offset
around the hemispherical dummy on the distal end of the model.
7) Pull 2 layers of Perlon stockinette over the model and tie it off on
the hemispherical dummy.
8) Screw the shuttle lock fully into the lamination anchor and tighten
the screw of the threaded clamping (torque value: 10 Nm).
9) Position the lamination anchor in the longitudinal residual limb
axis on the hemispherical dummy.
10) Bring the lamination anchor arms to the correct a-p and m-l posi­
tion. Never align the threaded clamping in the anterior or posteri­
or direction.
11) Optional: Adapt the anchor arms of the lamination anchor to the
model with a bending iron.
12) Replace the shuttle lock with the lamination dummy (see
Page 12).
13) Wrap the clamping section of the lamination anchor with plasta
tape to prevent contact with the lamination resin. This ensures
even clamping.
14) Pull the fibreglass roving through the holes in the anchor arms
and allow it to hang in a loop. If there are no holes, allow the
fibreglass roving to hang around the anchor arms in a loop.
15) Place 3 layers of carbon fibre cloth (e.g. 15 cm x 15 cm) offset
over the lamination anchor arms.
16) Pull 2 layers of Perlon stockinette over the model and tie off below
the cap screw of the lamination anchor.
17) Cut 1 piece of carbon fibre woven hose to size (1.3 times the
length of the plaster model) and pull it over the model.
18) Tie off the excess carbon fibre woven hose below the cap screw
of the lamination anchor and pull it over the plaster model.
19) Pull 2 layers of Perlon stockinette over the model and tie off below
the cap screw of the lamination anchor.
20) Pull on a soaked PVA bag.
21) Complete the lamination process with Orthocryl lamination resin.

22) After the lamination resin has cured, remove the lamination
dummy.

5.2.3 Installing the lamination dummy

1) Tighten the screw of the threaded clamping to a point where the
shuttle lock can still be screwed in and out.
2) Unscrew the shuttle lock from the lamination anchor.
3) Screw in the lamination dummy.

5.3 Final assembly

anchor.
2) The shuttle lock may be unscrewed from the thread by no more
than 3/4 of a turn to align it.
3) Secure the cap screw of the threaded clamping using Loctite®
and tighten using the torque wrench (10 Nm).
Screwing in the ratchet unit
Required materials: 710D4 torque wrench
>
► Screw the ratchet unit into the shuttle lock (torque value: 10 Nm).
