Definitions

  • the invention relates to a trigger comb for a knitting or knitting machine.
  • a withdrawal comb is often used, which is also referred to as a stop comb. It serves to take a first course and to pull away from the knitting points in a controlled manner.
  • the trigger comb has as a basic body on an elongate profile body, which forms a trigger needle carrier. It is provided with a series of parallel needle grooves, in which take-off needles sit.
  • Each trigger needle has a needle body in which a slider is slidably mounted.
  • a transverse bar grips the ends of the slide to move them synchronously in the needle longitudinal direction and thus to open or close the hook of the needle.
  • To adjust the cross bar is a cam plate with a link that converts a longitudinal movement of the cam plate in a transverse movement, which is transmitted to the cross bar.
  • the withdrawal comb which has a storage device for the storage of the deduction parts.
  • the storage device takes the shaft at spaced apart in the shaft longitudinal direction points, for example between two teeth of two spaced in the shaft longitudinal direction tooth pairs and clamps the shank of the holding part between preferably flat clamping surfaces (eg flat sides of a fixing plate and a Ausrichtblechs).
  • the storage device consists of at least one bent sheet metal part.
  • the sheet metal bending part is a carrier, the optionally provided with a bearing plate.
  • the trigger comb on a closer strip, which is designed as a sheet metal bent part.
  • the carrier used for the storage of the deduction parts consists of sheet metal, such as steel. In a first embodiment, it has angled portions, between which the trigger parts are taken. In a second embodiment, it carries a bearing plate, which is provided with the angled portions for aligning the trigger parts.
  • the angled portions form at least two rows parallel to each other.
  • the trigger parts are thus no longer located in needle grooves, as was the case in the prior art, but they are only held in the longitudinal direction of short and spaced locations of their shaft.
  • the length of these storage locations corresponds to the thickness of the sheet from which the carrier (or, if present, the storage tray) is formed.
  • bent sheet metal parts For the production of bent sheet metal parts, a wide range of usable manufacturing methods is available, which the skilled person can use depending on the accuracy requirement and the required quantity. These include stamping, bending and stamping and other cutting methods such as Laser cutting and bending process.
  • the carrier and / or the mounting plate have angled portions, which are formed for example by an angled edge, are provided in the cutouts. The remaining parts of the edge then form fingers, between which intermediate spaces for receiving the trigger parts are formed.
  • the trigger parts are preferably received lying flat. They have, for example, a rectangular, limited by two larger and two narrower flat sides cross-section, wherein the larger flat sides are preferably arranged lying in a common plane. This has the advantage that the haul-off comb can be used even with very narrow needle gaps.
  • a straightening plate may be provided which, for example, has the form of a metal strip which is arranged between two rows of angled portions of the bearing plate and / or of the carrier and has a preferably flat upper side.
  • the trigger parts depending on the embodiment of the trigger comb with their narrow sides or their larger flat sides.
  • the carrier together with the bearing plate or the bearing plate itself preferably has two mutually parallel rows of angled portions, which cooperate with spaced-apart portions of the trigger member. Each trigger member is then held between four angled sections which define in pairs two spaces between each other.
  • the said angled portions may be formed directly on the carrier or on a separate storage plate. It is also possible to do a number of the angled ones Form sections to the carrier and another row on the storage tray. It is only essential that at least two rows of comb-like arranged, angled portions are assigned to the trigger parts, between which they are stored. In other words, the trigger parts are mounted in two mutually parallel rows of slots or spaces in each case at spaced locations.
  • a fixing plate may be provided, which likewise has at least one row of angled sections, between which intermediate spaces for receiving the withdrawal parts are formed.
  • This fixing plate may e.g. lay flat on the trigger parts and be stretched against them to fix them.
  • the tensioning direction can be set in the direction of the angled sections.
  • the fixing plate may be fixed in its longitudinal direction, i. be stretched transversely to the angled portions against the trigger parts to eliminate the play between the trigger parts and the angled portions. In this way can be achieved with simple means a good orientation of the trigger parts.
  • the angled portions of the fixing plate can also serve to hold the trigger parts along their feet longitudinally with little or no play.
  • angled portions may be provided on the support plate or the carrier.
  • the deduction parts are preferably formed in two parts, each having a base body and at least one movably mounted closing part. While the main body of the trigger parts are preferably fixedly mounted on the support or the bearing plate, stand the Closing parts with a movably mounted closer strip in connection, which preferably has angled portions, between which the ends of the closing parts are taken.
  • the closer strip is also associated with a fixing strip, which may be formed as a sheet metal bent part.
  • the fixing strip and the closing strip preferably together define a groove in which the feet of the closing parts are mounted.
  • the movement of the closer strip on the carrier can be effected by a slide, which is for example also designed as a sheet metal bent part and engages with an angled edge in a formed between the closer strip and the fixing strip groove. It is longitudinally displaceable in this groove, but transmits transverse movements.
  • a slotted guide can implement a longitudinal displacement of the slider in a transverse movement of the same, which transmits via the closer strip on the closing parts.
  • the withdrawal comb with the exception of the trigger parts and their closing parts and possibly with the exception of some screws, rivets, bearings and other small parts of sheet metal parts and sheet metal bent parts can be produced.
  • the bent sheet metal parts are preferably free of welds. However, it is also possible to provide welds or welds for connection to other parts, including sheet-metal bent parts, or to connect the sheet-metal bent parts to one another.
  • the sheet metal parts and bent sheet metal parts are made of plastic. These plastic parts are then preferably connected to one another cohesively, for example by splices.
  • the described concept can also be applied when the closing part is designed in the form that it grips the stitches to be grasped, without creating a closed space at the withdrawal part in which the stitch is held.
  • the slider has a hook-like stitch-catching area which grips the stitches.
  • the trigger parts may be arranged lying flat in a plane, wherein they turn each other to their narrow sides. With a correspondingly narrow formation of the spaces between the angled portions of the support plate, the carrier and / or the Fixierblechs the trigger parts can also be arranged side by side so that they each other their broadsides, i. turn to their larger flat sides. With both concepts, a cost-effective, but precisely producible deduction comb is obtained.
  • FIG. 1 is a trigger device 1 illustrated on a knitting machine, which is designed as a flat bed knitting machine and illustrated by two needle beds 2, 3.
  • the needle beds 2, 3 each have mutually parallel needle channels with needles 4, 5 mounted therein, which are designed, for example, as latch needles or slide needles and serve to produce a knitted fabric. Locks for driving the needles 4, 5 are present, but not illustrated in detail.
  • a comb spacing 6 is formed, in which a deduction of the extraction device 1 deduction comb 7 can penetrate from below.
  • the trigger device 1 may also further extraction means, for example in the form of two take-off rollers 8, 9, which are arranged below the needle beds 2, 3 and can come into engagement with the fabric when the fabric has been guided by means of the trigger comb 7 far enough down ,

  • a channel is incorporated, through which a closing part 15 extends. This is designed like a slide and provided at one end with a foot 16 and at its other end with a locking lug 17.
  • the foot 16 is used for targeted longitudinal displacement while the locking lug 17 the opening and closing of the thread receiving space 13 serves.
  • the shape and configuration of the end 12, the thread receiving space 13, the locking lug 17 and the other details of the trigger member 10 can be varied within wide limits. It is essential that the thread receiving space 13 is opened and closed by relative movement of the slide member 15 to the main body 11 of the trigger member 10. The relative movement takes place according to the embodiment FIG. 4 by means of the foot 16 of the slide member 15 to the foot 14 of the trigger member 10 in the direction of the indicated arrow 18. There are also other embodiments possible in which the relative movement is produced in a different manner. Thus, it is possible to move the main body 11 relative to the slider 10.
