Dimensions (wxdxh) 115 x 99 x 127 cm (45 1/4" x 39" x 50") Weight 45 kg (99 lb). A dobby loom has a dobby mechanism, which is used to program the harness combinations for the weave pattern. Dobby is short for "draw boy" which refers to the weaver?s helper who was used to control the warp thread by pulling on draw threads. The dobby mechanism replaces the treadle/lam combination of the traditional floor looms. The performance of a multi-harness loom is vastly improved by using a dobby mechanism, as it overcomes the major problems associated with the use of a large number of treadles. A dobby loom allows you to select the combination of harnesses for every shed opening you wish to make. The great advantage of a dobby loom is that it avoids the necessity and the labor involved in making multiple tie-ups to treadle positioned underneath a loom. An investment in a Louët Dobby ensures many years of comfortable and productive weaving. The electronic dobby will give you almost unlimited harness combinations using a computer and software from Fiberworks PCW, Patternland, Weavemaker, Weave It, WeavePoint or Pro Weave, which all work with the Louët electronic interface.
