1.
Carefully check
that the two beams (ensouples) are parallel.
2.
Fix the rateau
on the two jumelles, near the rear roller.
3.
Mark on the rear
roller/beam the spot where each lame of warp should be, taking care that
they are well centered on the beam/roller (write down the measures taken, the
distance between the metal galette and the start of the work, the width
of the work…).
4.
Pass the verdillon
of the rear beam/roller through the loops (side opposite to the side with the
crosses, the encroix) of the crenilles, taking care not to forget
any thread.
5.
Replace the “safety”
threads (fixed on the warping machine or ourdissoir, generally in white
cotton) which separate the portées, with a warp thread which will be
stretched using two upholstery nails fixed on the beam.
6.
Place the crossed (en
encroix) end of the portées of each crenille on the rateau
approximately where they will be assembled.
7.
Distribute the
threads of the crenille equally between the nails of the rateau
and arrange the threads neatly on the verdillon.
8.
Wind the warp on
the rear roller/beam, tensioning it well (smooth the threads between your
fingers, do not let them dangle underneath, they must be even) so that the
threads are coiled taut evenly. Proceed with complete turns of the roller until
the crenille reaches the level of the rateau. You can place a
wooden slat or paper between every two turns of the roller/beam (so that the
threads remain at the same level).
9.
Look for the cross
(encroix, enverjure) of the threads at the front end of each crenille
(the cross marked when warping by two “safety” threads, generally colored).
Replace these safety threads with a rope that is stretched from one jumelle
to the other as close as possible to the rear beam. Take care to leave the
hooks free of use on the gâteaux, and to attach the rope to the jumelles
in such a way that it can subsequently be made independent of them.
10. Carefully remove the rateau. You can leave it
if you pass your heddles alone.
11. Smooth the threads of the end of the crenilles
and cut the loops of each crenille to the same length.
12. Pass a warp thread through the heddles so that you can
suspend them taut in front of the rope by attaching them to the jumelles (be
careful not to forget any heddles).
13. Pass the warp threads through the heddles (check that
there are no errors by grouping them into groups of six). Remove the threads
that support the heddle bars and detach the rope from the jumelles.
Unwind the warp until the heddle bars of each lame and the rope rest on
the loom board. Take a point of reference on the front beam/roller and tie the
knots in packs of six threads (take the opportunity to check one last time that
your threads are correctly passed through the heddles).
14. Pass the front verdillon over the knots,
dividing them into two bunches of three threads.
15. Mark on the front beam the exact location of each lame,
referring to the measurements taken at the beginning. Equalize the knots on the
verdillon and place it in the channel of the front beam/roller.
16. Pull the warp taut, pull the rope up against the rear
beam. Make four passes (passées) of cotton (smaller gauge than the gauge
of the cotton warp) stretched tightly in front of the front beam/roller, fix
them on the roller using upholstery nails at the front. Equalize.
17. Equalize at the back on the rope.
18. Pull the warp taut and caille it (minimum 15 mn).
19. Loosen then turn the front roller. Equalize behind and
tighten. Let the warp cailler. You can place a wooden slat or paper
between every two turns of the roller/beam, so that the threads remain at the
same level.
20. Repeat this operation until the entire warp is
on the front beam.
21. Remove the rope and replace it with two warp threads
stretched over the roller using the upholstery nails. Equalize and caille the
warp again.
22. Roll the roller backwards. Caille the warp (it
is no longer necessary to equalize) and repeat this operation until the entire warp
is behind again.
23. Make two passes (passées) of the warp at the
back and even out one last time.
24. The warp is ready.
