A loom is a frame within which the carpet is made, and also the
warp is tightened. Looms are applied to hold the warp threads
under tension so as to facilitate the interweaving of the weft
threads. A vertical rather than horizontal loom, is more comfortable
for workers and reasonably the most used. It should be mentioned
that this kind of loom was used by the carpet weavers who
participated in the present study. Weavers sit on a bench next to
each other and create individual knots row after row. The designs
upon which the carpet is shaped are chartered out on a graph by
which a map reader or another weaver instructs the graphic designs
to the workers who are knotting the carpet. Required tools in
this process are scissors, iron rod, levers, and comb beaters. When
the carpet is made, it is taken off the loom and then the designs and
patterns are trimmed by scissors.
