Double-needle bed raschel type warp knitting machine

Abstract

Two groups of weft shuttle magazines are configured for one double bar Rachel loom in order to manufacture spaced knitted fabrics for which the surface is reinforced through attached warp and / or warp. Two groups of longitudinal conveyors (13h, 13v) are subject to the two groups of the weft shuttle magazines. The two groups of longitudinal conveyors (13h, 13v) move mutually in opposite movement direction (36h, 36v). Moreover, the two groups of longitudinal conveyors (13h, 13v) pass horizontal yarn feeding areas (14h, 14v) placing the weft in turn, then pass the slightly oblique feeding areas (15h, 15v), strongly oblique first returning areas (16h, 16v), finally pass the other returning areas (17h, 17v) of the longitudinal conveyors (13h, 13v). The invention is characterized in that the movement rails of the two pairs of the longitudinal conveyors (13h, 13v) mutually pass and form one puncturing area (38). Moreover, the movement rails of the two pairs of the longitudinal conveyors (13h, 13v) cross at a deflection position (39h, 39v) between the slightly oblique feeding areas (15h, 15v) and the strongly oblique first returning areas (16h, 16v). The crossing position is located on a knitting position of the double bar Rachel loom. The compact building mode is realized through the design, wherein the weft can be conveyed to the knitting position in a larger speed through the weft shuttle magazines, thus the double bar Rachel loom with the building mode has higher production speed.

Description

technical field [0001] The invention relates to a double-needle-bar Raschel-type warp knitting machine for producing spacer knitted fabrics. The warp yarn, knitting yarn and pile yarn cooperate with the knitting needles on the opposite side and form and output the resulting spacer fabric web between the two bars. The weft thread supply device of the area between the rows of needles, wherein the weft threads are respectively woven into the upper layer of the spacer knitted fabric produced on the side of its supply device. Background technique [0002] Spacer knits have long been known under the name "wool"; they consist of two fabric layers which are joined to each other by pile yarns. A method for the production of double-pile plush knitted fabrics is known, wherein the fabric web is cut longitudinally by means of a tape cutter and produces velvet knitted fabrics, as well as complete spacer knitted fabrics in clothing, furniture covers, upholstery fabrics and web applicati...
