Definitions

  • the invention relates to a method for producing a pile fabric on a flat fabric serving as the base fabric, alternating according to the pattern tied pile loops and pile legs on two together weaving machine producing flat fabrics connected by Florhenkel, each pile-forming pile threads using a jacquard machine either the pile loop binding or the pile handle binding different binding weft threads of the two flat fabrics assigned are, the pile loops forming pile threads between one the pile side of the base fabric and a weft further weft thread of the basic goods are stretched and the Pile threads forming pile legs initially as pile handles between Weft threads of the two flat fabrics stretched and under training the pile leg between the two flat fabrics - with avoidance a contact of the cutting element with the apices of the pole loops - be separated.
  • a weaving method of this type is known from DE 199 18 171 A1.
  • On a double-protective double-carpet weaving machine becomes two flat fabrics generated, both as the base fabric of a pile or carpet fabric serve. Both basic fabrics are differentiated by pile handles Colors connected. In both flat fabrics and base fabrics are not patterned pile threads, so-called dead poles, mostly stretched involved.
  • the jacquard machine can select these pile threads and either for binding as a dead pole on the base fabric or for the formation of Pole handles in connection with the opposite base fabric move to subject training.
  • a so-called double pile fabric is created or double-pile fabric. By separating the pole handles in the middle between two pile fabrics or carpets are created for the two basic goods. Both Pile fabrics have both pile areas and areas in the pile layer with only closed pole handles.
  • the pole loops formed here have only small dimensions and are regularly significantly flatter than the pile legs in the pile areas. If you want to enlarge the pole loops with thicker shots, in Weft direction of adjacent pile handles spread in the warp direction. she form a cord-like pile surface in the weft direction. It is unsatisfactory. There can be no pile fabrics with acceptable pedaling properties and uniform pole height are generated. The pile loops and pile legs cannot be positioned anywhere on the pole surface.
  • EP 1 081 260 A1 is used for the production of a pile fabric
  • Pole loops and pile legs use a kind of rod weaving machine proposed.
  • the single-action rod weaving machine carries in every third tour on the pole side a thicker shot over which the pro Warp course each a selected pile thread forms a larger loop.
  • Cutting rod pole form element
  • the large pole loops formed in the process are pulled out the cutting rod separated and form upright, in the base fabric anchored pile legs. These pile legs are significantly longer than the pole loops formed on the goods base.
  • the Rod weaving machine works with one contact and requires for binding a series of pile loops or pile loops a total of three weaving machine tours. Because of the large mass of those to be entered within a tour The weaving machine can only cut the rod at low speed work.
  • the cutting rod heat up during the cutting process in such a way that when The ends of the pile legs exceed a certain temperature to melt. This affects the quality of the pile fabric produced. For this reason there is a further reduction in the working speed the weaving machine mostly unavoidable.
  • the height of the pole loops can also be determined using the method mentioned here do not adjust to the greater height of the pile legs if pile loops and pile leg side by side in the weft direction be positioned.
  • the cross section of the rod determines the height difference between pile legs and pile loops.
  • the pedaling comfort can only be ensured if the surface areas of the Carpets with pile loops are very small. Should the pole loop structure prevail, then the pile heights must be reduced by a shear process. The low and hard pole loops determine the pedaling comfort at a low level.
  • the object of the present invention is therefore to provide a method for Production of a pile fabric with any pattern arranged Propose pile loops and pile legs, in which the pile loops and the pile legs have a sufficient and approximately the same height have optimal alignment to the pole surface.
  • the amount of the total Pole layer should be limited according to the required treading properties be variable.
  • the procedure should work with two or three protections Two-speed can be implemented without additional speed limitation his.
  • the pile legs and the pile loops are on the pile surface can be arranged in any pattern. It is excluded that the means also spread the pile legs to spread the pile loops.
  • the size of the pole loops is determined by the choice of the dimensions of the lancets can be varied within the usual limits. For securing the uniform The height of the pile legs and the pile loops are not additional Operations required.
  • both the pile handles are as well as the vertices of the pole loops exactly positioned in terms of their position, so the loop structure is not due to faulty separations is affected.
  • the second flat weave that is only very short and patterned sections of the pile handle can be used for purposes can be used where an attractive appearance is not expected.
  • the process can be carried out on conventional double carpet or double pile weaving machines with a lancet arrangement in the middle compartment without limitation the usual working speed can be realized.
  • a Realization of the procedure with single shot entry is possible, required but of course several tours for the production of a pole row.
  • the described method basically also enables the sample Combination with a pile thread pattern on the base fabric and / or with a shot pattern.
  • Claims 6 and 7 define expedient procedures of Specialist training on weaving machines with three weft insertion levels.
  • Pile warp threads of different colors or different properties assigned can also be colored or structured patterned pile loops or Pile leg areas can be realized.
  • the accompanying the weaving process Pile threads can be used as dead poles in the basic fabric or in the second flat weave be involved (see claims 8 to 10).

On the base fabric only the pile legs 2261 remain, which together with the apices the pile loops 225 form the pile surface of the pile fabric 220.

In this way, you can create any color you want or structurally patterned pole surface with arbitrarily distributed pile legs and pole loops.
