8) Pull a soaked PVA bag over the model.
9) Complete the lamination process with Orthocryl lamination resin.
10) Once the lamination resin has cured, remove the PVA bag.
11) INFORMATION: Align an anchor arm that has been angled at
the factory in the posterior direction.
Move 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.
12) Place the lamination anchor at the socket end as required for
proper alignment and bring it into position.
13) Optional: Adapt the anchor arms of the lamination anchor to the
model with a bending iron.
14) Install the lamination dummy (see Page 18).
15) Stabilise and fix the lamination anchor with a sealing resin/talcum
powder mixture.
16) Pull one layer of perlon stockinette over the model.
17) Place two layers of woven carbon fibre (e.g. 15 cm x 15 cm) off­
set over the lamination anchor arms.
18) Pull one layer of perlon stockinette over the model.
19) Pull two layers of carbon woven stockinette over the model.
20) Pull two layers of perlon stockinette over the model and tie off
below the cap screw.
21) Pull a soaked PVA bag over the model.
22) Complete the lamination process with Orthocryl lamination resin.
23) After the lamination resin has cured, remove the lamination
dummy.
5.2 Laminating the transtibial socket
Required materials: torque wrench (e.g. 710D20), 711S4*
>
bending iron, 99B81 PVA bag, 623T3 perlon stockinette, 616B1
carbon fibre webbing, 699B1 fibreglass roving, 616G12 woven
carbon fibre, 616G15 woven carbon fibre stockinette, 617H119

1) If the lamination anchor has a threaded connector: Fully
screw in the screwed insert.
2) Tighten the cap screw of the threaded clamping using the torque
wrench (10 Nm).
3) Pull a soaked PVA bag over the model. The PVA bag should be
sealed by heat welding at the distal end.
4) Pull two layers of Perlon stockinette over the model.
5) Place three layers of woven carbon fibre (e.g. 15 c m x 1 5 cm)
with offset fibre alignment on the distal end of the model.
6) Pull two layers of Perlon stockinette over the model.
7) INFORMATION: Align an anchor arm that has been angled at
the factory in the posterior direction.
Move 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.
8) Place the lamination anchor at the socket end as required for
proper alignment and bring it into position.
9) Optional: Adapt the anchor arms of the lamination anchor to the
model with a bending iron.
10) Install the lamination dummy (see Page 18).
11) Stabilise and fix the lamination anchor with a sealing resin/talcum
powder mixture.
12) 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.
13) Place three layers of carbon fibre cloth (e.g. 15 cm x 15 cm) in an
offset arrangement over the lamination anchor arms.
14) Pull one layer of Perlon stockinette over the model.
15) Pull two layers of carbon woven stockinette over the model.
16) Pull two layers of perlon stockinette over the model and tie off
below the cap screw.
17) Pull a soaked PVA bag over the model.
18) Complete the lamination process with Orthocryl lamination resin.
19) After the lamination resin has cured, remove the lamination
dummy.
