Definitions

  • the present invention relates to a method for producing a three-dimensional knitted fabric, i.e. a knitted fabric, the surface of which is spatially shaped, e.g. with helmets or the heel of socks.
  • the shape is realized in a known manner by increasing and / or reducing stitches in certain areas of the knitted fabric.
  • All possible shapes, such as Balls or bowls can be produced without e.g. in the conventional spiked technique there is a line within which all the stitches are removed, so that the knitted fabric in the area of this line is subject to special loads.
  • the invention distributes, on the one hand, the increase or decrease or inactivation of needles over the entire area to be shaped, as a result of which the deformation of the knitted fabric no longer occurs along a line, but rather homogeneously in the entire knitted fabric.
  • the deformation at each individual point of increase or decrease or inactivation / activation of needles is no longer so great, since the increase / reduction / inactivation can be less at each individual point due to the large number of points. This means that the deformation of the knitted fabric at one point in the increase / decrease / inactivation is less than in the prior art, where in one or a few places the entire increase / decrease / inactivation required for the shaping took place.
  • the above locations are now evenly distributed over the area to be deformed by the invention, this distribution being as uniform as possible, ie homogeneous should.
  • the distribution can be carried out regularly, ie in a controlled manner, in such a way that all points of increase / decrease / inactivation are approximately equally far apart. However, these points can also be statistically distributed over the area to be deformed, as a result of which the creation of any texture which could represent a predetermined breaking point is avoided.
  • the degree of deformation is preferably determined by density, i.e. controls the mutual distance of the places where the increase / decrease / inactivation takes place. If a strong deformation is desired, these points are arranged in a higher density than in areas in which less deformation is desired. In this way it is possible to produce homogeneous textile pieces which, in the desired manner, have less deformed areas and more deformed areas. In this way, homogeneous knitted fabrics can be produced in all desired shapes.
  • a three-dimensional shape is achieved by increasing and / or decreasing stitches in several areas of the knitted fabric.
  • the number of stitches increased / decreased or split / combined should not be excessive, for example not more than ten stitches. If you increase several stitches within the knitted fabric in several places, you get a bulge of the knitted fabric at the points of increase. If you reduce the stitches in the knitted fabric at a large number of points, the knitted fabric contracts in this area, so that in turn a bulged area is created.
  • the increase and decrease can be combined as desired to achieve desired shapes.
  • Another possibility of producing three-dimensional knitted fabrics is that needles are deactivated in certain areas of the knitted fabric, while the needles are continued in the other areas. By later activation of these inactivated needles e.g. after one or more rows of stitches, the knitted fabric contracts in this inactivated area, which can be used again in the desired manner to achieve certain shapes. If you e.g. in the case of a knitted fabric in the edge areas of the flat knitting machine, inactivating needles and repeating this inactivation at intervals of a few rows of stitches of different widths, a spherical structure with a very homogeneous structure is obtained.
  • the needles should only be inactivated over a few rows of stitches, so that excessive deformations of the knitted fabric are avoided at one point.
  • the width (number of needles) of the inactivation can be changed alternately, so that a scattering of the deformed points in the deformation region can also be achieved in this way. These points are located at the points where an inactivated area is adjacent to a knitted area.
  • FIG. 1 shows a knitting scheme for knitting a spherical knitted fabric by inactivating needles in the edge region of the knitted fabric
  • FIG 3 shows the creation of a bulged area by increasing and decreasing according to the present invention.
  • FIG. 1 shows a knitting scheme for producing an approximately spherical knitted fabric.
  • the figure shows the actually knitted textile surface 10.
  • the shape of the textile is now achieved by partially or completely inactivating 10 needles within a region b of the textile surface on both sides, so that knitting is not carried out over one or more rows of needles in this region .
  • the stitches are then connected to the stitches knitted last. This means that during the time that the needles are not activated in the edge area b of the knitted fabric 10, certain areas of the course rows simply disappear.
  • the rows of stitches before and after the area which has been eliminated are thus simply knitted together, as a result of which the knitted area in this area is drawn together in accordance with the number of rows of stitches not knitted.
  • the points at which deformation occurs are points 11. At these points 11, the inactivated areas adjoin the knitted areas. Therefore, the width of the inactivated area, ie the number of inactivated needles, is continuously varied, so that the deformation points 11 are evenly distributed within the deformation area b. In this way, one also avoids a defined structuring of the decrease, which in turn would be associated with a weakening of the knitted fabric.
  • the mutual distance between the inactivations 12, 14, 16 is relatively constant, so that the deformation points 11 also have an approximately uniform distance in the direction of the meshing.
  • the needles are deactivated in a first short area 12, which for example only has 20 needles.
  • the stitches are deactivated in a region 14 which extends over the entire width b of the shaped region. In this case, the inactivation would affect, for example, 60 needles.
  • the needles are activated over a width 13 which lies between the two widths mentioned above, for example with 40 needles. In this way, the deformation points 11 are distributed uniformly over the deformation width b.
  • the inactivated areas 12, 14, 16 are interrupted again and again by knitted areas 18, in which knitting is carried out over the entire width of the knitted fabric, which in the direction of the meshing leads to approximately uniform intervals between the points 21.
  • knitted areas 18 In the middle of the knitted fabric 10 there is an area 20 in which knitting is carried out, while an area 22 extends further outward in which the knitted fabric already has non-knitted rows of stitches at a distance of several rows of stitches. These non-knitted areas increase towards the outside, as can easily be seen from the drawing. If one now keeps in mind that the knitted sections 18 are connected to one another at their upper and lower edges, it is easy to understand that the knitted fabric 10 shown in FIG. 1 should have an approximately spherical shape .
  • the inactivation 12, 14, 16 in the knitted fabric runs over two successive courses.
  • the degree of deformation is set by the distance, ie the sequence of inactivations and the width of the inactivation areas 12, 14, 16. The wider the inactivation areas and the sequence of inactivations, the greater the deformation.
  • FIG. 1 describes a method for producing three-dimensional knitted structures by inactivating needles
  • FIGS. 2 and 3 show a knitting method in which a three-dimensional shape is produced by increasing or decreasing stitches.
  • 2 shows a method in which the three-dimensional shape of the knitted fabric takes place in a defined area 30.
  • a stitch is doubled in a first stage 32, ie a stitch is split into two stitches, so that there are now two wales instead of one wale.
  • point 34 there is a further splitting of the two wales into two wales so that there are now four wales which are again split into eight wales at position 36.
  • area 30 is the widest.
  • the increase according to the invention does not take place in an area 30 as in FIG. 2, but at five different points 50, 52, 54, 56, 58, at each of which a stitch is divided into two stitches (split) and then combined again into a stitch.
  • the duration of the division is different for the five digits, so that there is a homogeneous distribution of the increase / decrease points within the knitted fabric.
  • knitted stitches 60 are arranged between the areas 50, 52, 54, 56, 58 of the increase / decrease, which serve to increase the homogeneity of the knitted fabric in the entire shaped area.
  • the increase is less long and in the areas 50, 58 lying at the edge, the increase is only relatively short, for example the increase / splitting there extends over one to ten rows of stitches.
  • the present invention is therefore suitable for producing all possible geometric shapes such as spheres, cones and all types of bulges of regular or irregular type.
  • Both the increase / decrease in the stitches and the partial inactivation of the needles in a row of stitches can be at an uneven spacing and to a different extent. It can also be controlled or carried out statistically in order to achieve the highest possible homogeneity. When distributing these points and distributing the size of the increase / reduction / inactivation, care must be taken, however, that overall an approximately uniform shape of the knitted fabric is achieved over the entire area.

Abstract

Ce procédé sert à fabriquer un tricot tridimensionnel, c'est-à-dire un tricot dont la surface est façonnée dans l'espace. On obtient une structure tricotée tridimensionnelle, homogène et résistante en augmentant et/ou en diminuant le nombre de mailles dans des zones déterminées. Le nombre de mailles est augmenté/diminué à plusieurs endroits uniformément répartis dans la surface à façonner en trois dimensions. On peut fabriquer de manière similaire un tricot tridimensionnel en désactivant au moins partiellement les aiguilles de tricotage dans la zone à façonner, sur au moins une rangée de mailles (12, 14, 16), puis en les activant à nouveau plus tard, alors que l'on continue à tricoter dans les autres zones (18) du tricot.
