Definitions

  • the invention relates to a flat knitting machine with at least a needle bed and one sliding along the needle beds Sled, the at least one lock with needle selection devices and has needle countersink.
  • the wiper surfaces on the needle counter and the needle counter position the lock of a knitting machine determine the shape and the size of a stitch.
  • With double-faced R-R knitted fabrics give slim stitches the most beautiful stitch pattern. This is due to a narrow wedge area on the needle countersink reached.
  • result round stitches are the most beautiful stitch pattern.
  • These round stitches become wide culvert areas on the needle countersinks needed so that as many needles as possible at the same time be held in the deepest culvert position. To this Way, the tendency that the just moved in can be reduced Stitch from the previous stitch the prevailing tensile forces pulls some knitting thread and thereby this stitch a little smaller again.
  • the shape of the wedge surface can also determine whether all Needles are drawn in equally far during the cultivation or whether in the same needle counterbore position are drawn in at different distances can.
  • a needle countersink has been proposed in CH 448 358 of the two winder surfaces for the production of two different ones Has mesh sizes. Those needles that one have high needle foot, are on one Kulier Chemistry and the needles with the low needle feet on the other culvert area. So with this needle countersink produce two different mesh sizes, however the size ratio of the stitches to each other is fixed and not is changeable.
  • the present invention has for its object a To create flat knitting machine in which an influencing the mesh shape and / or size by changing the wedge area is possible without replacing the needle counterbores.
  • the task is started with a flat knitting machine mentioned type according to the invention solved in that with the Needle counters are each movably arranged on the needle countersink Kulierelement interacts, regardless of the needle countersink can be controlled and that together with the needle countersink depending on its position Kulier inhabit of different sizes and / or Forms.
  • This Kulierelement it is possible both with double-faced R-R knits as well as with single-faced Smooth knitted fabrics to achieve the optimal stitch pattern.
  • the needle counterbore itself can, for example, with a Narrow Kulier Structure be equipped, the only effective is when an R-R knitted fabric is to be made.
  • the wedge element there may also be an area at a corresponding adjustment of the Kulierelements the Kulier Structure broadened the needle countersink, so that a total broad cul area as it is used for the production of single-surface smooth knitted fabric is optimal.
  • the adaptation to the different types of binding is with an inventive Flat knitting machine possible in a very simple way. An exchange of the needle counterbores is no longer necessary. It all that is required is a corresponding control of the wedge elements be made.
  • Depending on the adjustment of the wedge element can be a narrow or a wide cul area be adjustable.
  • the Kulierelement can also be a guide surface for the needle feet have a propulsion after the stitching of a stitch the needle at a defined distance from the wiper surface causes. This allows the tension on the Knitting thread works, reduce. The different knitted ties must be realized with a wide variety of knitting threads become. If the forces in the knitting threads during the knitting process get too big, they tear. A knitted fabric with such Thread breaks ("burst") are rejects.
  • burst knitted fabric with such Thread breaks
  • the Kulierelement can also be a guide surface for the Have needle feet, with which the insertion depth of certain needles compared to the draw-in depth of the needle counter sinking surface is changeable.
  • stitches can be formed have a size difference to those stitches on the needle counter sinking surface are formed. It can even a continuous adjustment of the mesh size difference a stepless adjustment of the feed depth of the certain Needles are realized.
  • the wedge element during the knitting process is adjustable.
  • the mesh shape and -size can then be stopped without stopping the machine during the Adjust the knitting process.
  • the locks also work according to the pressure lock technology, it is even possible that Define the wiper area for each individual stitch.
  • the knitting lock 100 from FIG. 1 has a needle drive part 110, which cooperates with a limiting part 120. There is also a leading needle counterbore on the knitting lock 100 130 and a trailing needle counterbore 140 are provided if the direction of movement as indicated by arrow 150. The needle counterbore 130 has no function. Also points the knitting lock 100 two Kulierimplantation 160 and 170, the cooperate with the needle core 130, 140 as follows is described.
  • the device 1 shown in Fig. 2 corresponds to the needle countersink 140 and the wedge element 170 from FIG. 1.
  • the needle countersink is designated here with 2 and the Kulierelement with 3.
  • the Kulierelement 3 is pivotable at the pivot point 4 on the needle counterbore stored. By acting in the direction of the Arrow 11, the Kulierelement 3 is pivoted into its inner end position. An existing wiper surface 8 is thereby disabled.
  • the feet 10 of the not shown Needles participating in the knitting process slide along a plane 5 of the needle counterbore 2 until it is under a narrow Kulier Chemistry 6 on the countersink 2 their the one in question Mesh size have reached the corresponding wedge position. In this culvert position, the needle feet 10 through a surface 7 on the countersink 2 positively guided, whereby a high Uniformity of mesh size is achieved.
  • the narrow one Kulier arrangements 6 results in an optimal stitch pattern for R-R knitted fabrics.
  • FIG. 3 shows the arrangement 1 from FIG. 2 when the wiping element 3 by acting in the direction of arrow 12 in his outer end position is pivoted. Now it closes Kulier relations 8 to the Kulier Activities 6 of the countersink 2 and this widens them. Due to the widened wetting area 6 and 8 can now multiple needle feet 10 in at the same time the lowest wedge position. This gives an optimal mesh pattern for single-surface smooth knitted fabrics.
  • the wiper surface lies 6 of the needle countersink 2 and the wiper surface 8 of the wiper element 3 in different levels.
  • a needle selection device not shown
  • a knitted lock also not shown with pressure lock technology that specified each individual knitting needle can be whether it over the narrow Kulier Structure 6th or should be cultivated over the wide cul area 6 + 8.
  • Needle feet 10 that are only halfway up the needle counterbore 2 are applied, are calculated on the narrow surface 6 and the Needle feet 10, which lie against the needle counterbore with the entire foot height, are cultivated on area 6 + 8. That way it is possible that in knitted fabrics in which within a Knitting row a change from a single-surface weave a double-faced weave takes place, every stitch in the optimal shape is formed.
  • the arrangement 60 shown in FIG. 5 corresponds to the arrangement 1 from FIGS. 2 and 3, but with the additional possibility that the needles after reaching the wedge position can perform a defined relief movement.
  • the arrangement again has a countersink 2 and a wedge element 30 on that at point 40 to its inner end position is pivoted and thus the position shown in Fig. 2 occupies.
  • the wiper element 30, however, has an additional one Guide surface 9, which the needle feet 10 after culturing on the narrow wedge surface 6 of the needle counterbore 2 again Push it up a little bit and drive out the needles a little, which reduces the tension in the knitting thread.
  • a positive guide surface 15 is provided on the needle counterbore 2, which brings the needles to their rest position.
  • a pressure lock technology can be designed for every single knitting needle whether she should carry out the relief movement or Not.
  • the needle feet 10, which are only half the height of the needle counterbore experience no relief movement while the needle feet, which lie against the needle counterbore with the entire foot height, are detected by the curved surface 9 and thereby the Carry out relief movement.
  • the wedge element 30 is in its outer End position swiveled (not shown), so the selected Needles either on the narrow wedge surface 6 or the wide cultivation area 6 + 8 can be cultivated.
  • the arrangement 50 from FIGS. 6 and 7 enables formation of meshes with a different mesh size than the one with Kulier relations 6 of the needle countersink 2 formed stitches.
  • the arrangement again has a needle countersink 2 with a narrow one Kulier relations 6 and a positive guide surface 7.
  • the associated wedge element 31 is again about a pivot point 41 pivoted and in Fig. 6 in its inner end position shown by acting in the direction of arrow 11 ''.
  • the needle feet 10, which are only half a foot on Needle countersink 2 are applied to the narrow surface 6.
  • the wiper surfaces 6 and 7 form one Forced operation.
  • the needle feet that are at the full height of the foot Needle countersink 2 are applied to the wide wedge area 6 + 8 calculated.
  • the forced guidance is through the surfaces 7 and a further surface 14 is formed on the wedge element 31.
  • the Kulierelement 31 is acted upon by Direction of arrow 12 '' pivoted into its outer end position.
  • the feet of the needles which have a mesh size corresponding to that Form the needle counterbore position, lie at half the height of the foot Needle countersink 2 and are cultivated over the area 6.
  • the Surfaces 6 and 7 again form a constraint for them Needles.
  • the feet of the needles which are supposed to form a larger stitch, than it corresponds to the needle counterbore position, lie with the entire foot height on the needle counterbore 2. Your way to the creation extends over the plane 5 and formed on the needle counterbore 2 the Kulier Chemistry 6 to that formed on the Kulierelement 31 Level 13 and then to surface 81.
  • This surface 81 is the wiping surface for the larger stitches and also forms with the mesh delimiting surface formed on the wedge element 31 14 a forced operation.
  • the wiping element 31 can be shown in FIG. 6 innermost swivel position continuously up to its outermost, 7 pivoted position. This makes possible a stepless enlargement of the stitches on the Kulier Chemistry 81 are formed, compared to those who the Kulier Chemistry 6 are formed.
