offset arrangement on the distal end of the model.
4) Pull two layers of Perlon stockinette over the model.
5) CAUTION! Do not bend the anchor arms of the lamination
anchor.
Move the lamination anchor arms to the correct a-p and m-l posi­
tion.
6) Set the 4X3 lamination dummy onto the pyramid of the lamination
anchor.
7) For 4R63, 4R100: Place the 4X52 lamination dummy on the prox­
imal side of the lamination anchor. The lamination dummy remains
in the prosthetic socket.
8) Place the lamination anchor at the socket end as required for
proper alignment and bring it into position. Use the marking on
the 4X3 lamination dummy to do so.
9) Stabilise and fix the lamination anchor with a sealing resin/talcum
powder mixture.
10) 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.
11) Place three layers of carbon fibre cloth (e.g. 15 cm x 15 cm) in an
offset arrangement over the lamination anchor arms.
12) Pull one layer of Perlon stockinette over the model.
13) Pull two layers of carbon woven stockinette over the model.
14) Pull two layers of Perlon stockinette over the model and tie off in
