Abstract: A method for weaving a pile fabric with areas having a corded structure, a backing fabric being woven on a weaving machine by inserting backing weft yarns during successive weft insertion cycles between binding and tension warp yarns, while pattern-weft yarns are inserted outside the backing fabric, and are covered by pile warp yarns forming cords. Successive series of different pattern-weft yarns are inserted into the pile fabric in areas having a corded structure and at least one pattern-weft yarn of each series is running essentially above the warp yarns in a first part of its trajectory and is forming the pattern, and is covered by pile warp yarns essentially forming cords in a second part of its trajectory, so that a predetermined pattern or design is formed. This enables the color palette and/or the effect palette to be modified across the width of the weaving machine with weft effects.

Abstract: A method for face-to-face weaving of shadow velours fabrics in which two velours fabrics are woven with pile forming pile yarn tufts having a pre-determined orientation, each velours fabric having pile zones with a different aspect, because their pile yarn tufts have a different orientation, in order to form a pre-determined figure on each velours fabric and in which overlapping pile zones, having differently oriented pile yarn tufts are formed on the pile faces, facing one another, in parts (31), (32), (33), (34), (35), (36) of the face-to-face fabric, so that the projection of each figure produces a figure on the opposite pile face, which is different from the figure formed on the other pile face. This method makes it possible to determine the figures of the two velours fabrics independently of one another.

Abstract: In face-to-face weaving pile fabrics with high pile density, groups of three weft yarns (1-3), (4-6) are inwoven in respective openings between binding warp yarns (7), (8), (9) (10) crossing each other, and non-pile-forming pile warp yarns are inwoven, while pile warp yarns are alternately interlaced in the top and the bottom backing fabric over a weft yarn according to a two-shot weave. In series of four successive weft insertion cycles in each case three weft yarns (1), (2), (3) are inserted for the top backing fabric (30) and three weft yarns (4), (5), (6) for the bottom backing fabric (31). A weaving machine inserts two weft yarns one above the other per weft insertion cycle and by weft disengagement or weft cancellation in the course of two cycles per series inserts only one weft yarn. Two pile-forming pile warp yarns after a pile change are interlaced over a weft yarn.

Abstract: A method for weaving face-to-face carpets consists of figures formed in an upper fabric and in a lower fabric. Different pile warp threads are woven-in alternately as non-working dead pile in the upper and lower fabrics to form figure-forming pile running from the upper fabric to the lower fabric and vice-versa. A double pile is woven-in with a transition in the weft direction from the figure-forming pile warp thread exiting the lower fabric to a figure-forming pile warp thread exiting the upper fabric. Carpet fabrics with face-to-face carpets separated into upper and lower fabrics is formed of different pile warp threads alternatively woven-in as non-working dead pile in the upper and lower fabrics which protrude as figure-forming pile. A color transition from one figure-forming pile warp thread to another figure-forming pile warp thread results in a woven-in double pile in the fabrics.

Abstract: A method for weaving fabrics with a two-sided rib structure, such as false boucl{acute over (e)} fabrics, comprises forming a fabric on a weaving machine from weft threads and warp threads of a series of warp thread systems, with sets of at least two weft threads running one above the other. Each warp thread system comprises at least three pattern warp threads of which two opposite each other, respectively along the upper side and the lower side of the fabric, form a number of ribs. The pattern warp threads are alternately rib-formingly passed around over one or several sets of weft threads and are interlaced in the fabric, while each additional pattern warp thread is inwoven in the fabric between weft threads of the sets over which other pattern warp threads are rib-formingly passed around.
