A method for weaving pile fabrics with pile-free zones, in which, on a weaving loom, in successive series of at least two successive weft insertion cycles in each case at least one ground weft thread () and at least two effect weft threads (),() having mutually different appearance-determining properties are inserted at well-defined weft-insertion levels, in which the effect weft threads (),() in each series are inserted in successive weft insertion cycles, and in which, in order to create a predetermined effect in at least one pile-free zone, the warp threads (-); (-); (-) are positioned with respect to the weft insertion levels such that at least one effect weft thread (),() runs on the pile side substantially uncovered.

Method of weaving of a pile fabric with pile-free zones

A method for weaving pile fabrics with pile-free zones, in which, on a weaving loom, in successive series of at least two successive weft insertion cycles in each case at least one ground weft thread () and at least two effect weft threads (),() having mutually different appearance-determining properties are inserted at well-defined weft-insertion levels, in which the effect weft threads (),() in each series are inserted in successive weft insertion cycles, and in which, in order to create a predetermined effect in at least one pile-free zone, the warp threads (-);(-);(-) are positioned with respect to the weft insertion levels such that at least one effect weft thread (),() runs on the pile side substantially uncovered.

A face-to-face weaving machine comprising upper () and lower spacers () for extending in the warp direction between two fabrics (), () and a weft insertion device (), (), () for inserting weft yarns () between the spacers (), (), said spacers being carried out as a rigid element with a first (), () and a second part (B), (B), the vertical intermediate distance between the first parts (), () of the spacers () being shorter than said distance between the second parts (B), (B) such that the weft yarns () can be inserted between said second parts (B), (B). This invention also relates to a method for weaving pile loop fabrics, in which at least three weft yarns () are inserted above one another during successive weft insertion cycles on a face-to-face weaving machine, in which an upper () and a lower backing fabric () are woven, and loop weft yarns () are inserted between the two fabrics (), () and are kept at a distance of the backing fabrics (), (), and in which pile warp yarns () form pile loops over loop weft yarns (), so that two pile loop fabrics are woven, whereas pile warp yarns () are interlaced in the upper () and the lower backing fabric () alternately and are cut through between the two fabrics (), (), so that zones with a cut pile are obtained on the fabrics.

Weaving machine and method for weaving fabrics with pile loops

A face-to-face weaving machine comprising upper ( ) and lower spacers ( ) for extending in the warp direction between two fabrics ( ), ( ) and a weft insertion device ( ), ( ), ( ) for inserting weft yarns ( ) between the spacers ( ), ( ), said spacers being carried out as a rigid element with a first ( ), ( ) and a second part ( B), ( B), the vertical intermediate distance between the first parts ( ), ( ) of the spacers ( ) being shorter than said distance between the second parts ( B), ( B) such that the weft yarns ( ) can be inserted between said second parts ( B), ( B).

A method for manufacturing a loop pile fabric with a varied appearance includes a woven backing fabric. Loop weft yarns ( A), ( B) are provided outside the backing fabric, and loop warp yarns ( ), ( ), ( ) are so provided that they are alternately inwoven in the backing fabric and form a pile loop ( ), ( ) over at least one loop weft yarn ( A), ( B), and the loop weft yarns ( A), ( B) are subsequently removed. By providing first ( A) and second loop weft yarns ( B) with a different thickness, pile loops ( ), ( ) of different height are formed. To obtain a fabric in which both pile loops ( ) and cut pile ( ) occur subsequently a top part can be removed from a number of pile loops ( ). In areas ( ) where no pile loops are formed effect backing weft yarns ( B) with laterally protruding filaments can be inwoven in the backing fabric. A loop pile fabric can be manufactured according to this method.
