Embodiment Construction
[0031] figure 1is a schematic cross-section along the warp direction of two carpets C1 and C2 which are woven simultaneously one over the other on a face-to-face weaving machine or loom There are two lead-in members not shown.
[0032] Picks (picks) P1 to P32 in figure 1 is shown in , and defines the lead-in loop for weft yarns.
[0033] Each carpet C1 or C2 comprises a respective backing fabric F1 , F2 and a respective pile D1 , D2 extending from one backing fabric F1 or F2 to the other. Backing fabrics F1 and F2 may also be referred to as ground fabrics. The tufts D1 and D2 are to be separated from each other by a knife K belonging to a cutting device not further shown. The knife K travels along the median plane π0 of the weaving machine on which the carpets C1 and C2 are knitted. The plane π0 extends parallel to and between the backing fabrics F1 and F2. It is at an equal distance from both fabrics.
[0034] The backing fabric F1 comprises two binding warp yarns b1 a...

The present application relates to a method for weaving a fleece and a fleece having shaded cut pile regions. Wherein, the top and lower backing fabrics are woven with the following yarns: filling warp yarns, binding warp yarns, weft yarns including inner weft yarns and back weft yarns, the inner weft yarns are introduced at the pile side of the filling warp yarns, and the back weft yarns are introduced at the rear side of the filling warp yarns . Patterned pile yarns are interwoven into the top and lower backing fabric. The groups of weft threads are introduced into at least one backing fabric in successive weft insertion cycles. In the first series of weft insertion cycles and at least in the first backing fabric, the pattern pile yarn is turned from the outside around the first inner weft yarn, and then from the inside around the second successive inner weft yarn before it is turned from the outside around the successive weft yarns. weft yarn diversion; in the second series of weft insertion cycles and at least in the first backing fabric, the pattern pile yarn is diverted from the outside before it is turned from the inside around the first successive inner weft yarn and from the outside around the second successive inner weft yarn Turn around the back weft.
Description
technical field [0001] The present invention relates to a method for simultaneously knitting two pile fabrics with shaded cut pile areas on a face-to-face knitting machine. The invention also relates to a fleece having shaded cut pile regions which can be woven using this method. Background technique [0002] In the field of weaving carpets on face-to-face looms, it is known, for example, from DE-C-319 324 to obtain two different orientations of the pile legs by varying the structure of the backing fabric of the two carpets . The weft threads are incorporated in the backing fabric at two different heights: the inner weft threads are introduced on the pile side of the tension warp threads, and the rear weft threads are introduced on the other side of the tension warp threads. Each opening of the binding warp thread comprises only one weft thread. Considering the bottom fabric shown in the drawings of this German patent, if it wraps around an inner weft knot directly follow...
