Warping The Sectional Beam

Figure 62 - Adjusting the Size of the Section
Extra care to correctly center and adjust the width of each warp section will
result in more perfect tension while weaving.
Make sure that the threads are going on to the Beam in flat layers. If you
notice that warp piles up at the hoops, the section of the warp is too wide. If
the warp falls down at the hoops, the warp section is too narrow.
If any of the above is happening, gently unwind the warp (into a box,
perhaps) and pivot the front reed on the Tension Box again until you get
perfectly flat layers. This is very
important
, otherwise you will end up
having different length threads in one section, since the circumference of the
Beam within the section is not going to grow evenly. This uneven tension will
cause tension problems.
Counting Turns Or Yardage
To determine the length of the warp you are putting on the Beam, you need
to count either turns, revolutions, or yards.
To count turns, you can do it in your head, but it is more reliable to use a
digital or mechanical revolution counter.
Counting revolutions even with a digital counter will only give the
approximate warp length, because the circumference of the Beam will
increase slightly with each rotation. This is called “Beam Build Up”.
To count yards with a Yardage Counter while warping the Sectional Beam,
you need to place the Yardage Counter at the front of the Tension Box. You
should use an extra thread for measuring yardage, because if you use one of
the threads from your warp section, that particular thread would have a
