Definitions

  • the present invention relates to a method for manufacturing pile fabrics, such as for example carpets, wherein two base fabrics are woven composed of first ground warp threads and first weft threads, respectively, while each base fabric comprises at least one pile warp thread, parts of which extend between both base fabrics in a pile-forming manner, wherein at least some pile warp threads are non-pile-forming over at least a part of their length, and wherein the pile-forming parts of the pile warp threads between both base fabrics are cut, so that two pile fabrics are obtained.
  • Such a method can be performed on a weaving machine, such as for example a double-face weaving machine, for manufacturing pile fabrics, such as for example carpets, comprising a weft insertion device configured to insert in each case at least two weft threads at different weft insertion levels between ground warp threads and pile warp threads in successive weft introduction cycles, a shed-forming device provided to position said ground warp threads and pile warp threads in each weft introduction cycle with respect to the weft insertion levels in such a way, that two base fabrics are woven one above the other from first ground warp threads and first weft threads, respectively, whereas parts of pile warp threads extend in a pile-forming manner between both base fabrics and at least some of the pile warp threads are non-pile-forming over at least a part of their length, and a cutting device provided to cut the pile-forming parts of the pile warp threads between both base fabrics, so that two pile fabrics are obtained.
  • a weaving machine such as for example
  • the present invention relates in particular to such a method for manufacturing carpets whose properties come very close to replicating the typical properties of hand-knotted carpets. More particularly, it relates to manufacturing relatively lightweight and flexible and relatively easily pliable carpets, whose pile exhibits a multicoloured pattern (or design or motif) which is readily recognisable on the back of the carpet.
  • At least some of the non-pile-forming parts - preferably all non-pile-forming parts - of the pile warp threads are thus held together in one or several additional fabrics which may be removed as a coherent whole during weaving on the weaving machine.
  • This may be achieved, for example, by providing means on the weaving machine which advances each additional fabric, as weaving progresses, and transports it away towards a receiving device. These means comprise, for example, a picker roll. Transporting away the additional fabrics hardly delays the weaving procedure, if at all, and the two pile fabrics no longer have to undergo an aftertreatment in order to remove redundant parts of pile warp threads, as a result of which this method results in a higher productivity and a reduced risk of damage compared to the known method.
  • the method according to the invention makes it possible simultaneously to manufacture, in a highly productive manner, two high-quality carpets having the properties of hand-knotted carpets, these properties more specifically meaning that the pile has a multicoloured and clearly defined pattern whereas no, or hardly any non-pile-forming parts of pile warp threads are bound in in the base fabrics.
  • the pattern is clearly visible on the back of the carpets and the carpets also have the typical lightness and pliability of hand-knotted carpets. These typical properties can also be maintained when the pile density is relatively high.
  • a respective associated additional fabric is formed on the back of each base fabric, at least some of the non-pile-forming parts of the pile warp threads are woven in with the additional fabrics, and the pile-forming parts of the pile warp threads between both base fabrics are cut along a cutting plane which is situated between the base fabrics.
  • the additional fabric which is associated with the upper base fabric is formed above the upper base fabric, whereas the additional fabric which is associated with the lower base fabric is formed below the lower base fabric.
  • a number of pieces of pile warp thread are in this case preferably obtained which comprise a pile-forming part and a non-pile-forming part, at least one pile leg is formed on each pile fabric by a pile-forming part of a piece of pile warp thread whereas a non-pile-forming part thereof is woven into the associated additional fabric, and said pile leg, which is formed by the pile-forming part of said piece of pile warp thread, is pulled out of the pile fabric when the associated additional fabric is removed.
  • two additional fabrics are formed between the base fabrics and are respectively associated with the one and with the other pile fabric, at least some of the non-pile-forming parts of the pile warp threads are woven into the additional fabrics, and the pile-forming parts of the pile warp threads are cut according to a cutting plane situated between the additional fabrics.
  • the pile-forming parts which are cut are pile-forming parts of pile warp threads which are successively interlaced with the one and in the other base fabric, and/or are pile-forming parts of pile warp threads which are successively interlaced with the one base fabric and an additional fabric associated with the other base fabric, and/or are pile-forming parts of pile warp threads which are successively interlaced with the one and the other additional fabric.
  • an additional fabric is formed between the two base fabrics, at least one pile warp thread partly woven into the additional fabric runs from the additional fabric to the one base fabric in a pile-forming manner, at least one pile warp thread partly woven into the additional fabric runs from the additional fabric to the other base fabric in a pile-forming manner, and the pile-forming parts of pile warp threads between both base fabrics are cut along a first cutting plane which is situated between the additional fabric and the one base fabric and along a second cutting plane which is situated between the additional fabric and the other base fabric, so that the additional fabric is separated from the two pile fabrics.
  • the second weft threads may be bound in in each additional fabric by second ground warp threads and/or by non-pile-forming parts of pile warp threads.
  • Said first weft threads preferably comprise ground weft threads and backing weft threads, whereas each base fabric is woven from respectively first weft threads which are bound in by respectively first ground warp threads and/or by respectively non-pile-forming parts of pile warp threads, and from respectively backing weft threads which are situated on the back of the base fabric, and that the pile-forming parts of the pile warp threads which form pile on the pile fabric are interlaced in each case over a backing weft thread.
  • the pile-forming pile warp threads are also clearly visible on the back of the pile fabric at the location of each pile leg formed on the pile side.
  • the pattern formed by the pile legs is also very clearly visible on the back of the pile fabrics.
  • connecting warp threads are provided in each base fabric which, in the base fabric, run alternately on the pile side of one or several first weft threads and run over a backing weft thread which is situated on the back of the respective base fabric, so that each base fabric is connected to at least some of the backing weft threads which are situated on the back thereof.
  • This method can be carried out on a weaving machine for simultaneously weaving two pile fabrics which is adapted to manufacture pile fabrics having an appearance resembling the appearance of a hand-knotted fabric, and to obtain, after the pile warp threads running between both pile fabrics have been cut, two pile fabrics which do not have to undergo any further treatment in order to remove redundant yarns.
  • This weaving machine can have the characteristics indicated in the second paragraph of the present description, wherein the weaving machine is adapted to weave in, before the pile warp threads are cut, at least some of the non-pile-forming parts of the pile warp threads, together with second weft threads, to form at least one additional fabric.
