Abstract
The invention relates to a method and related equipment for manufacturing shaped fabrics or anatomically shaped tubular hosiery and knitwear items, obtained with Raschel looms having preferably two parallel needle beds and automatic latch needles. During the knitting process, by gradually varying the height of the needle bed and of the sinking plane lying above with respect to the needles sliding in the same bed, knitting density can also be suitably changed. As a consequence, concerned anatomic parts such as the bodice and ankles of a pair of tights or a stockings as well as the waist and sleeves of a sweater can be shaped with higher accuracy and effectiveness.
Claims16
A method for producing textile items with “tricot-Raschel-crochet” linear looms (TR2) for warp knitting, having at least a first bed (FNA) of needles (N, N1), comprising the step of manufacturing at least a textile item (CM), characterized in that it comprises the step of moving at least said first needle bed (FNA) during said step of manufacturing said textile item (CM), said needle bed (FNA) moving in order to vary the knitting density by varying the height of the sinking plane (PAB) with respect to the needles (N) sliding in the same bed (FNA).
A “tricot-Raschel-crochet” linear loom for warp knitting, comprising at least a first needle bed (FNA), characterized in that at least said first needle bed (FNA) is mounted movingly onto the loom and in that it further comprises means (GL, EX, EX2, L1, L2) for moving selectively said first needle bed (FNA) during the operation of the linear loom (TR2).
