[A Specification was laid open to inspection under Sect. 91 of the Acts, Aug. 20, 1946.] [Class 74 (ii)] In making elastic fashioned articles (such as body belts, bandages, girdles and corselets) on a warp knitting-machine, the warp threads are divided into zones (e.g. A, BSP1/SP, C) located side-by-side, by omitting needles of one row over small spaces D, feeding warp threads to the other row of needles only over these spaces and laying in, in one or more zones, elastic and nappable or non-nappable non-elastic weft threads to extend in straight lines between the warp-knitted courses. The wefts are introduced through guides FSP1/SP, FSP2/SP, the guides Fl reciprocating more quickly than the guides FSP2/SP; and the articles are fashioned by varying the tension of the elastic wefts GS and by the size, nature and'distribution of the elastic and non- elastic zones. The tension is varied by holding the elastic yarn for varying periods during laying-in, to produce differing degrees of subsequent contraction and the frequency of the weft insertions may be varied, as between zones I, II and III of Fig. 4. Separating courses Tr, between the articles, are formed by omitting weft threads within nappable zones A and laying them in after every fourth course only in the other zones. The warp threads may be of rubber, cotton, cellulose, or silk and individual warps may differ. The rubber thread of the elastic wefts may be covered with cotton, cellulose or silk. The non-elastic wefts may be of cotton, cellulose, wool or waste yarn and be covered with fancy thread (e.g. artificial silk). The nappable wefts are of readilyteasable cotton, cellulose, or wool. Selvedges serving as sewing strips may be formed in the same way as are the inter-zonal parts D.
