Thrumming is a technique in which small pieces of wool or yarn (thrums) are pulled through fabric to create a wooly layer.The term thrum originally referred specifically to worthless pieces of warp thread which remained after weaving a piece of fabric using a loom, though its meaning has since broadened to include any small pieces of wool or thread which are used in a similar way.
In general, weaving involves using a loom to interlace two sets of threads at right angles to each other: the warp which runs longitudinally and the weft (older woof) that crosses it. (Weft is an Old English word meaning "that which is woven"; compare leave and left. [a]) One warp thread is called an end and one weft thread is called a pick.
Drawloom, with drawboy above to control the harnesses, woven as a repeating pattern in an early-18-hundreds piece of Japanese figured silk. A drawloom is for weaving figured cloth. In a drawloom, a "figure harness" is used to control each warp thread separately, [20] allowing very complex patterns. A drawloom requires two operators, the weaver ...
The word dobby is a corruption of "draw boy," which refers to the weaver's helpers who used to control the warp thread by pulling on draw threads. A dobby loom is an alternative to a treadle loom . Both are floor looms in which every warp thread on the loom is attached to a single shaft using a device called a heddle .
The enchanted loom is a famous metaphor for the human brain invented by the pioneering neuroscientist Charles S. Sherrington in a passage from his 1942 book Man on his nature, in which he poetically describes his conception of what happens in the cerebral cortex during arousal from sleep:
The selvage (US English) or selvedge (British English) is the term for the self-finished edges of fabric. In woven fabric, selvages are the edges that run parallel to the warp, and are created by the weft thread looping back at the end of each row. The selvage of commercially produced fabrics is often cut away and discarded. [26]
One end of a rapier, a rod or steel tape, carries the weft yarn. The other end of the rapier is connected to the control system. The rapier moves across the width of the fabric, carrying the weft yarn across through the shed to the opposite side. The rapier is then retracted, leaving the new pick in place.
A graphic with Arabic text distinguishing raw fibers from processed threads and woven fabric. Warping: The warp yarns are arranged on a beam to prepare for weaving. The warp threads are held taut and parallel, and as such must be strong and durable. Weaving: During weaving, the weft yarn passes over and under the warp yarns in various patterns.
