14) Wrap the clamping section of the lamination anchor with plasta
tape to prevent contact with the lamination resin. This ensures
even clamping.
15) Place 2 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) Pull 2 layers of carbon fibre woven hose over the model and tie off
below the cap screw of the lamination anchor.
18) Pull 2 layers of Perlon stockinette over the model and tie off below
the cap screw of the lamination anchor.
19) Pull a soaked PVA bag over the model.
20) Complete the lamination process with Orthocryl lamination resin.
21) After the lamination resin has cured, remove the lamination
dummy.
5.2.2 Laminating the transtibial socket
> Required materials: 710D4 torque wrench, cap screw, 711S4*
bending iron, 99B81 PVA bag, 623T3 Perlon stockinette, 616B1
carbon fibre cloth strap, 699B1 fibreglass roving, 616G12 carbon
fibre cloth, 616G4 fibreglass mat, 616G15 carbon fibre woven
hose, 617H119 Orthocryl lamination resin 80:20 PRO
1) Pull 2 layers of Perlon stockinette over the model and tie it off on
the hemispherical dummy.
2) Position 1 layer of carbon fibre cloth strap circularly around at the
height of the MPT (mid-patella-tendon) point.
3) Medially and laterally, position 1 layer of carbon fibre cloth strap
(width: 5 cm) respectively from the hemispherical dummy to the
socket brim.
4) Anterior and posterior, position 1 layer of carbon fibre cloth
strap (width: 5 cm) respectively from the hemispherical dummy to
the socket brim.
5) Position 4 strips (approx. 5 cm x 3 cm) of fibreglass mat on the
carbon fibre cloth strap to line the anchor arms.

6) Position 2 layers of carbon fibre cloth (e.g. 15 c m x 1 5 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 13).
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.
