in this loom, warps are winding around upper beam and lower beam. sitting place of weaver is fixed, because the woven carpet is regularly pulled down and conveyed to the backside of loom; consequently carpet might be woven with length of a little less than twice length of loom.

In cases, when loom is wooden or metallic, loosening or tightening warps are done by wedge or screw.

This kind of loom is the basic pattern of looms, which are made today with screw or metal made.
