Weaving: definition of warp and weft and the operative cycle of shedding, picking and beating in textile manufacture. Definition of weaving explains formation of woven structures by interlacing warp (lengthwise) and weft (crosswise) threads, identifies a warp thread as an end and a transverse weft length as a pick, notes consecutive picks from a folded length of yarn, and states that shedding (separating the warp into two sheets), picking and beating in are the primary operations of a single weaving cycle.
