Reed (weaving)
A reed is part of a loom, and resembles a comb. It is used to push the weft yarn securely into place as it is woven, it also separates the warp threads and holds them in their positions, keeping them untangled, and guides the shuttle as it moves across the loom.〔"Reed." ''The Oxford English Dictionary''. 2nd ed. 1989.〕〔1911 Encyclopædia Britannica〕 It consists of a frame with lots of vertical slits. The reed is securely held by the beater.〔 Floor looms and mechanized looms both use a beater with a reed, whereas Inkle weaving and tablet weaving do not use reeds.
==History==
Modern reeds are made by placing flattened strips of wire (made of carbon or stainless steel) between two half round ribs of wood, and binding the whole together with tarred string.〔 Historically reeds were made of reed or cane, however modern reeds are made of metal wires.〔 John Kay in 1738 first used flattened iron or brass wire, and the change was quickly adopted. Previously the cane was split by pressing it against a spindle that had knives radiating out of it at the appropriate distance apart. The split cane was then bound between the ribs of wood in the same manner as the wire is now.
The wire is flattened to a uniform thickness by passing it between rollers, straightened, given rounded edges and smoothed. The final step is to cut the wire to the correct length and insert it into position.〔 The tarred cord that binds the reed together is wrapped around each set of wooden ribs and between the dents to hold the ribs together.
The length of the metal wire varies depending on the type of fabric and the type of loom being used. For a machine powered cotton loom, the metal wires are commonly long. For hand powered floor looms, around is common.
