Definitions
- the invention relates to a needle for knitting machines one pivoted and the needle hook in one end position closing tongue and a method for Mesh parts with a knitting machine made with such needles is equipped.
- the dividing of meshes is technically complex Knitted pieces a relatively frequently desired process.
- Such a mesh is advantageous, for example in the transition from a single-surface knitted fabric to one double-faced knitted fabric.
- Mesh sharing also allows a whole bunch of knitted ties that aren't otherwise would be producible.
- the present invention has for its object a Propose latch needle with which a real stitch-dividing process is possible, and specify a procedure as with such latch needles can be divided can.
- the task is done with a needle for knitting machines with a pivoted and in one end position the needle hook closing tongue released, which is characterized that between the tip of the tongue in the one that closes the needle hook End position and the beginning of the rounded area a needle lay section of the needle hook head is.
- the Tongue in the closed state either the needle hook head completely or it ends immediately before the rounded Area of the hook head. This means that a stitch that glides over the closed tongue, directly from the end of the tongue jumps the rounded hook head and from there into the mesh of the knitted fabric made up to now glides.
- the needle hook is now designed so that before the rounded area of the Needle hook head is arranged on a stitch support section the stitch after sliding down from the tip of the tongue can rest. So this section allows you to hold the Mesh.
- the stitch support section can be, for example, from a straight one Section of the free leg of the needle hook is formed his.
- the leg is therefore simply extended in a straight direction compared to tongue needles according to the prior art.
- at the mesh support section can have another configuration however, also have a recess that holds the Mesh allowed with even higher security. This can Recess approximately V-shaped and / or of a wave-shaped Formation of the free leg of the needle hook is formed his.
- Another way to keep the stitch on to improve the stitch support section is to Surface of the needle in the area of the stitch support section see above to shape that stitch only with increased resistance can slide over it.
- the needle can also be a so-called spring tongue needle, where the tongue of the needle against the resistance of a spring is movable in its two end positions.
- Such needles are already known and can be used with particular advantage Use shoulder processes.
- the beginning of the method according to the invention corresponds to that Procedure for passing a stitch from one needle to the other the opposite needle.
- Facilitating implementation of the needle hook of the opposite needle between the stitch leg and the needle shaft of the stitch originally holding needle can in a conventional manner by means of a spreading spring on the needle, which connects the stitch leg pushes outwards, are made possible.
- the stitch support section in contrast to the previously known latch needles now to hold the stitch to be divided in this area and then by pushing the needle in the stitch to let the needle hook slide while the opposite The needle already holds the stitch in its needle hook.
- At the end of the process is the stitch with its head and one Leg on the needle and the needle originally holding the stitch with the other leg in the hook of the opposite needle.
- Such a method can be done on a flat knitting machine as well as on a circular knitting machine become.
- FIG. 1a the front area of a latch needle 3 '' is behind shown the prior art.
- the needle 3 " has a needle neck 32 ", a needle head 33 and a needle tip 35 am End of the needle hook.
- a tongue 31 is provided that is around a pivot point D that lies on a line 100, is rotatably mounted.
- the tongue 31 is in her the needle hook closing end position shown.
- the end 38 of the tongue covers the needle tip 35 and ends immediately at the beginning of the rounded area of the hook head 33. This means that a stitch that goes over the tongue 31 and the tip of the tongue 38 slides directly onto the rounded area of the hook head 33 jumps and from this into the mesh below the needle 3 "slides.
- tongue needle 3 according to the invention a needle neck 32 opposite the needle neck 32 "of the needle 3" is extended and has a correspondingly deeper needle hook.
- the free leg 34 of the needle hook is also here longer than with the needle 3 '', so that there is between the tip 38 of the tongue 31 and the hook head 33 a stitch support section 40 results on which a stitch can be held. This means that a retracting movement of the needle 3 stitch sliding over the tongue 31 and the tongue tip 38 first jumps to the stitch support section 40 and can be held there when the needle 3 is no longer retracted becomes. Only by withdrawing the Needle 3 then slides the stitch over the hook head 33 into the Mesh like the 3 '' needle.
- FIG. 1c and 1d show alternative configurations of the invention Needles 3 “', 3" “, each also with Stitch support sections 40 ', 40 "are provided.
- the needle 3 '' 'from Fig. 1c has the free leg 34' of the hook the needle 3 "'has an approximately V-shaped recess 41, the Tip is rounded. The rounding at the top goes over in a straight line 43, which leads to the hook head 33, and on the opposite side in a straight line 42 leading to the needle tip 35 runs there.
- Through the recess 41 is with the needle 3 '' 'an even better hold of the stitch on the stitch support section 40 'than given for the needle 3.
- Fig. 1d shows a needle 3 ""
- the needle 3 '' 'from Fig. 1c is very similar.
- the stitch support section 40 " also provided with a rounded recess 44, the but now with arcuate sections 45, 46 to the needle tip 35 or to the hook head 33.
- the Needles 3 '' 'and 3 "" With both needles, the Needles 3 '' 'and 3 "", the depressions 41, 44 through a corresponding wavy design of the free legs 34 'or 34' 'of the needle hook formed.
- FIG. 2 shows the Stitch 5 originally holding needle 3 on the needle bed 1 and the needle arranged on the opposite needle bed 2 3 'in its basic position.
- the needle 3 is in the direction of the arrow A can be moved outwards and inwards in the direction of arrow B.
- the needle 3 ' can be driven out in the direction of arrow C. and pull back in the direction of arrow B.
- the stitch 5 of the last row of stitches knitted 4 is held in the hook space 36 of the needles 3 of the needle bed 1.
- a pull-off device moves the knitted fabric 4 in the direction of the arrow Z down. With this pull-off force arises in the stitch 5, which is on a knock-off wire 12 supports a tension necessary for the stitch formation and for a transfer process to the needle bed 2 and for that stitch division method shown here is necessary.
- FIG. 3 shows the needle 3 driven out in the direction of arrow A so far, until stitch 5 opens tongue 31 and on the needle shaft slides up to a breast 37 on the shaft of the needle 3.
- a spreading spring 38 is arranged spreads the leg 5 'of the stitch 5 laterally from the needle shaft. This makes it possible when the needle is driven out 3 'in the direction of arrow C the hook of this needle 3' between to pass the shaft of the needle 3 and the stitch leg 5 ', until the syringe 35 'of the needle hook is above the mesh head 5 is located.
