Definitions

  • the invention relates to a device for producing a spacer knitted fabric, in particular a spacer knitted fabric with a fabric surface spacing of more than 14 mm. Furthermore, the invention relates to a method for producing such a spacer knitted fabric.
  • the two textile surfaces are connected by pile threads together.
  • the height is the distance between the two textile surfaces, which are interconnected by a pile thread.
  • a pile thread is often used a monofilament thread.
  • a spacer knit can be produced on a circular knitting machine with knitting cylinder and dial.
  • the one then tubular knitted surface is made with the needles of the dial and the other also tubular knitted surface with the needles of the knitting cylinder. Both knitted surfaces are connected with the monofilament running back and forth between them. The distance of the knitted surfaces is dependent on the distance between the knitting cylinder and the dial.
  • the distance between the dial and the knitting cylinder can not be made arbitrarily large to meet the desire to produce larger Kick surfaces distances to meet. Because the distance between dial and knitting cylinder must be bridged by the needles when they are expelled. A larger needle ejection requires a longer path in the needle lock, which requires longer locks. If longer locks are used, the productivity of the machine is reduced to the same extent, because longer locks have the consequence that fewer lock curves are possible over the circumference of a circular knitting machine. The system number at the diameter of the circular knitting machine is then reduced, which means fewer courses per machine revolution.
  • From the DE-OS 103 20 533 is a circular knitting machine for producing spacer knits known.
  • a circular knitting machine for producing spacer knits known.
  • Slide needles are used. Distances between the knitted surfaces of up to 14 mm can be achieved with this machine.
  • needles require locks, which have a lock curve not only for the needle but also for the slide. Such locks are more expensive than locks for latch needles.
  • the application comes up against limits, if the distances of the knitted surfaces should be greater than 14 mm, because the then required over-shoots longer locks are necessary. It then applies the above with respect to the productivity of the knitting machine. If longer locks are used, the productivity of the machine is reduced to the same extent, because longer locks have the consequence that less lock curves are possible over the circumference of a circular knitting machine.
  • the distance of the two textile surfaces depends inter alia on the tongue or hinge lengths of the latch needles.
  • the connecting thread of the two textile surfaces must be inserted in the catching position both in the Rippnadel as well as in the cylinder needle.
  • both needles can be extended to the maximum extent that the thread located in the hook, which is used for stitching, still remains on the in-reserve needle tongue and does not slide over the inner edge of the needle tongue on the needle shaft.
  • the distance between the two textile surfaces in the use of latch needles on the max. Hinge length limited. This is especially true in a knitting machine according to US 6,122,690 , In this knitting machine, two needle cylinders face each other coaxially.
  • Both needle cylinders are equipped with latch needles.
  • This document discloses the transfer of stitches of a needle on a first knitting cylinder to a needle on a second knitting cylinder.
  • the distance between two knit fabrics is limited by two times the hinge length minus one times the hook size, since the pile thread is inserted into both hooks of the knitting machine needles. It can thus be produced spacer fabrics with a distance of about 10 mm between the knitted surfaces.
  • two groups of needles are present, each forming a needle contour and are used to produce a knitted surface. Between two knitted surfaces extend sections or legs of a pile thread. This is guided by means of a group of assisting parts respectively in the catching area of the needles of one or the other needle contour, in order to be anchored in the respective knitting surface.
  • the distance between the two needle contours is thus bridged by the Vorlegemaschine. The size of the distance is no longer defined by the maximum achievable Nadelaustrieb or in the case of latch needles by the distance between the tongue tip in tongue return and needle hook.
  • Tongue pins determine the path that a loop or loop held in the hook may travel until it slides over the open tongue in reserve and is thus knocked off the needle during needle withdrawal.
  • the device according to the invention is therefore particularly suitable for equipping with latch needles, wherein in principle also slide needles can be provided.
  • the Nadelaustrieb can remain limited to the customary for producing single-layer knit fabric, which only small needle strokes and thus small lock curves are required.
  • a large number of knitting systems can be installed on a circular knitting machine and a large number of courses can be produced in one cylinder revolution.
  • the device according to the invention therefore enables economical operation even when producing spacer knitted fabrics with fabric surface pitches of more than 14 mm.
  • the knitting machine according to the invention allows the production of spacer knits not only with high number of stitches per revolution (high system density) but also with high rotational speeds of the knitting cylinder.
  • the low required ejection of the latch needles coincides with the budding, which is necessary for the production of simple, smooth knitwear.
  • the presentation parts In principle, it is possible to design the presentation parts so that they are movable between two yarn transfer points, namely the yarn transfer point of the first font and the yarn transfer point of the second font back and forth. However, it is preferred to move the presentation parts between a passive position and a yarn transfer position. The Passive position lies approximately halfway between the two yarn transfer positions.
  • the group of submission items is divided into two subgroups. The first subgroup is assigned to the needles of the first fontur while the second subgroup is assigned to the needles of the second fontur. This means that each needle contour has its own pile thread feeder in the form of master parts. This concept allows both the setting of very small Fonturab remedies and thus very small Kitchens distances as well as the setting of very large Kick Square distances.
  • the presentation parts can be moved in principle in different ways. It is preferred to store and move them longitudinally displaceable. The advancing movement or thread transfer movement can then be achieved, as the movement of the knitting tools (needles, in particular latch needles) through a lock, which is engaged with feet of the Vorlegemaschine.
  • the inventive concept is generally suitable for knitting machines, even for flat knitting machines. However, it is preferably used in circular knitting machines.
  • the first needle bed is designed as a knitting cylinder.
  • the second bed may also be a knitting cylinder or a dial. In both cases, the second needle bed (knitting cylinder or dial) is preferably aligned coaxially with the first needle bed.
  • the knitting machine thus obtained can be adjusted by varying the distance between the two knitting cylinders or between dial and knitting cylinder to different Knitting surface distances and thus Polfadenschenkelinn.
  • the Vorlegemaschine can be arranged in a circuit board ring, which is the gap between is arranged adjacent to the two knitting cylinders or between dial and knitting cylinder.
  • the two groups above are arranged at an angle to each other and oriented. In addition, they are movable in directions which are at said angle to each other. Preferably, this angle is a right angle. This is especially true in the case of circular knitting machine with dial and knitting cylinder. In the case of a circular knitting machine with two knitting cylinders, this angle can also be a right angle or an angle deviating from a right angle.
  • the advantage of this arrangement is that the presentation parts, when they are in passive position (retreat position), release the space between the hooks of the two needle contours.
  • a plane parallel to the flat sides of the presentation parts and thus to the channel walls of the guides of a group of the presentation parts is preferably parallel to a plane which is parallel to the flat sides of the needles and the channel walls of the needles.
  • This also applies to the second group of assistants and needles. This is especially true in the case of a circular knitting machine with dial and knitting cylinder. This results in a clear and reliable construction.
  • the angle between the leadership of the presentation element and the leadership of its associated needle is about 45 degrees in a preferred embodiment, this angle is less than 45 degrees.
  • the presentation parts may alternatively be accommodated in the needle beds.
  • additional channels are provided for feed parts between needle channels.
  • individual needle channels in place with needles Assembling parts are fitted.
  • the master parts are then expelled further than the needles to bridge the distance between the two needle contours.
  • the presentation parts can move the pile thread both pushing and pulling.
  • both needle beds are equipped with presentation parts.
  • the presentation part can then be designed like a slender slider which has a notch for receiving the thread at its end face.
  • the presentation parts can be solid. However, they preferably have an end consisting of two lamellae. Alternatively, they may be formed as a whole of two lamellae which abut each other.
  • the lamellae for example thin steel sheets, preferably have the same matching contour. They can be loosely connected or connected together. The slats allow a retracting needle hook between them, where they can be spread slightly. This facilitates the yarn transfer from the Vorlegeteil to the needle.
  • FIG. 1 is as a section of a knitting machine 1, a first needle contour 2, consisting of individual, designed as latch needles 2a to 2h and a second needle contour 3, consisting of also formed as a reed needles 3a to 3h illustrated.
  • the needles 2 a to 2 h of the first needle contour 2 are preferably offset by a half pitch against the needles 3 a to 3 h of the second needle contour 3.

It is then possible to provide the presentation parts 5, 6 with a hook-like end with which then the pile thread in the direction of the needle 2, 3, in which it is to be inserted, is pulled and not pushed as described above, and thus submitted. With this arrangement, the movement with which the pile thread is inserted into the hook 25 of a needle 2, 3 is reversed in comparison to the above example. This can have advantages in the detection of the pile thread by the Vorlegemaschine 5, 6 as well as when inserted into the hook 25 of the needles 2, 3.
