单词 loom
释义
loom

Science and Technology
  • A device used to weave any cloth, braid, ribbons, rugs, tapestry, etc. that is made by two sets of threads intersecting at right angles with those in one direction passing alternately over and under those in the other direction. The loom holds the warp (longitudinal) threads under tension. Each warp thread passes through a heddle, allowing selected threads to be raised, thereby creating a space (shed) through which a shuttle passes, drawing through a weft (lateral) thread, then between the ‘teeth’ of a comb-like reed. The reed is held on a frame so that it can be swung to beat the warp, one line at a time, firmly into place. At intervals the woven material is pulled towards the weaver, across a cloth beam, and wound on to a roll, bringing more of the warp within reach. There are many designs of loom, varying greatly in size and including looms specialized for particular tasks.
