The warp-weighted loom may have originated in the Neolithic period. The earliest evidence of warp-weighted looms comes from sites belonging to the Starčevo culture in modern Serbia and Hungary from late Neolithic sites in Switzerland. [4] This loom was used in Ancient Greece, and spread north and west throughout Europe thereafter. [5]
Tablet weaving dates back at least to the 8th century BCE in early Iron Age Europe [1] where it is found in areas employing the warp-weighted loom. [2] Historically the technique served several purposes: to create starting and/or selvedge bands for larger textiles such as those produced on the warp-weighted loom; to weave decorative bands onto ...
The sizing machine improved the process by sizing a warp before putting it into the loom. The warp threads are first wound onto a large beam, which is then placed at one end of the sizing machine. Then the warp is drawn off the beam and passes through a bath of boiling size, between sets of rollers and cooled, dried and rewound onto another beam.
In weaving, the shed is the temporary separation between upper and lower warp yarns through which the weft is woven. The shed is created to make it easy to interlace the weft into the warp and thus create woven fabric. Most types of looms have some sort of device which separates some of the warp threads from the others.
In general the supporting structure of the loom is called the frame. It provides the means of fixing the length-wise threads, called the warp, and keeping them under tension. The warp threads are wound on a roller called the warp beam, and attached to the cloth beam which will hold the finished material. Because of the tension the warp threads ...
Swivel weaving. The swivel weave is a weaving technique that incorporates a decorative element into the fabric by using small shuttles that insert additional weft thread around selected warp threads, while the main weft thread forms the fabric's structure.
Balanced plain weaves are fabrics in which the warp and weft are made of threads of the same weight (size) and the same number of ends per inch as picks per inch. [3] Basketweave is a variation of plain weave in which two or more threads are bundled and then woven as one in the warp or weft, or both.
The threading of a Jacquard machine is so labor-intensive that many looms are threaded only once. Subsequent warps are then tied into the existing warp with the help of a knotting robot which ties on each new thread individually. Even for a small loom with only a few thousand warp ends, the process of re-threading can take days.
