The oriental rugs are made on a loom. There are two types of looms.
The horizontal loom
The horizontal loom is the most loom employed in rug production. This is remarkably simple consisting four pegs and two parallel wooden crossbeams are laid out on the ground. Horizontal loom is widely used by nomads, who are constantly on the move. This type of loom is easy to dismantle and transport with unfinished rug, as nomads are at constant move in search of new Pastures for their kattles and camels.
The Vertical Loom:
The vertical loom is a more sophisticated version of the horizontal loom. The vertical loom has two fixed parallel wooden or steel uprights, into which crossbeams are slotted. large and extra-large city carpets are on vertical loom. This is fairly large in size and several weavers can work side by side.
Weaving looms differ considerably in size and sophistication, but all operate on exactly the same principle, which requires a secure frame on which to tie the warp strands. This is achieved by constructing a rectangular framework, usually of wood, which may be either of fixed dimensions or adjustable in size. On fixed frames, the weaver can only make rugs in sizes smaller than the inner dimensions of the frame; adjustable frames allow one or more of the beams to be extended so that larger rugs can be woven. On most adjustable looms the vertical beams are fixed and one or both of the horizontal beams, which hold the warp strands in place, can be moved up or down the frame.
