This International Standard defines terms related to harnesses for Jacquard weaving machines used in the textile industry, with the aim of presenting a standardized, prescribed phraseology. It identifies the parts of, and positions on, the harness and establishes a nomenclature for those parts. Excepting special cases, the Jacquard machine is positioned such that the centre of hook insertion for the fully equipped Jacquard machine corresponds to — the centre of drawing-in width in weft direction (see definition 7), and — the centre of comberboard depth, drawing in warp direction (see definition 6). Where there are special rules for the manufacture of a harness, a hook distribution plan is necessary. NOTE In addition to terms given in the two official ISO languages (English and French), this International Standard gives the equivalent terms in German, under the responsibility of the member body for Germany (DIN). However, only the terms and definitions given in the official languages can be considered as ISO terms and definitions.
