Info
A weaving loom is an apparatus for making thread into cloth by weaving strands together at right angles. Warp threads run lengthwise, and woof threads run crosswise in a woven fabric.
During weaving, every other warp thread is raised up and the alternate ones pulled down to create a "tunnel" if observed from the edge of the cloth. A shuttle, which looks like a miniature canoe, contains a bobbin of woof thread within it, is "thrown" through the tunnel.
The laybar (in red) carries a comb-like device called a reed (in black). The teeth of this reed-comb separate the warp threads and push the new woof thread sideways into the previous ones to "beat-up" the cloth and create a tight weave.
