until the end of the warp touches the last Harness you are using. Make them
out of a strong non-stretchable linen or cotton cord. You will need to make
one Extension Cord for each section in your Sectional Beam. For each
Extension Cord:
1) Measure a piece of cord long enough to reach from the axle of the
Warp Beam, at least one and a half revolutions around the Beam
and then reach to the back most Harness.
2) When measuring the length of the cords, take into account that,
when the warp is attached to the Extension Cord the knot between
the cord and the warp needs to fall between the Crosspieces of the
Sectional Beam, not on them. This will keep the warp smooth on
the Beam so it doesn’t go over the knots created when attaching
the warp to the cords.
3) Now double that length and cut it. All Extension Cords should be
exactly the same length, so cut them all at the same time.
4) Take the two ends of the cord and knot them together, using an
overhand knot.
5) Wrap the cord around the center bar of the sectional beam with a
larks head knot. You will also use a larks head knot to secure the
warp threads to the extension cord.
Using a Tension Box
The Tension Box is an essential tool for Sectional Warping, which:
1. Puts threads under even tension.
2. Spreads threads to the proper width of the section.
3. Makes a thread-by-thread cross.
Sectional Beam Calculation
First, you must calculate the number of spools or cones of yarn you will
need. Each section is wound onto the Sectional Beam separately; therefore,
you’ll need to have one spool or cone for each end in that section. For
example, if your section is 2” wide, with sixteen E.P.I., you would need
thirty-two spools or cones of yarn.
To prepare for Sectional Beam warping, we need to calculate:
1. how many spools we need to wind
