Carpet having a shadow effect and method for weaving a carpet fabric having a shadow effect

Abstract

A carpet having a shadow effect comprises a backing fabric having weft threads (S) and tension warp threads (S, S), further comprising pile warp threads (P) interlaced with the weft threads (S) of the backing fabric and forming pile elements, the weft threads (S) being provided in groups (G) of weft threads repeatedly appearing in a warp direction, each group (G) of weft threads providing a relative positioning of the weft threads (S) thereof relative to at least one tension warp thread (S, S), a weft thread (S) of a group (G) being either positioned on a pile side relative to a tension warp thread (S, S) or on a back side relative to this tension warp thread (S, S) in a respective relative positioning, a first group (G) of weft threads having a first relative positioning of the weft threads (S) thereof and a second group (G) having a second relative positioning of the weft threads (S) thereof different from the first relative positioning, wherein the first relative positioning and the second relative positioning provide a substantially mirror-symmetrical arrangement with respect to each other relative to a plane of symmetry (Sy) extending in the weft direction, and/or wherein in the first relative positioning and the second relative positioning weft threads (S) positioned at a first group end region (E) in the warp direction and weft threads (S) positioned at a second group end region (E) in the warp direction have a different relative positioning with respect to at least one tension warp thread (S, S).
