Description

Flat knitting machine with auxiliary needles that can be moved individually Pattern device The invention relates to a flat knitting machine with from individually movable auxiliary needles of existing pattern device according to patent 330 834.

It is known that individually: movable auxiliary needles from a lower To move the rest position upwards in accordance with the pattern. It is also known individually movable auxiliary needles from an upper rest position in a selection according to the sample move down. Should the usual jacquard device be used for these types of movement Find use and the uniformity that a hole in the jacquard card is a Petinet opening or a press sample mesh in the goods are preserved, so it is essential that the individually movable auxiliary needles both during manufacture of pressed samples as well as in the production of Petinet samples either patterning on the chair needles for the production of press samples and scrutinizing on the cover needles for the production of petinet patterns, or non-patterning on the stool needles for prevention the formation of press patterns and non-patterning on the needles to prevent have an effect on the formation of Petinet patterns, i.e. either must be in both cases Pattern types those selected by the jacquard machine and from the lower one or the - upper rest position upwards or downwards brought auxiliary needles' the pattern formation, or with both types of pattern, the ones that remain in the rest position must be used Auxiliary needles bring about the formation of the pattern.

If now, e.g. B. in the production of Petinetxnustern from their Rest position by the jacquard machine in the working position moved auxiliary needles prevent the pattern formation, on the other hand, in the production of pressed patterns, the off their rest position brought into working position by the jacquard machine induce the formation of press patterns, it is not necessary that a jacquard device with two knife boxes is used, in which the knife boxes on with several noses provided jacquard sinkers act in such a way that during manufacture of press patterns z. B. the first knife box acts on the jacquard plate, that the jacquard sinkers selected from the jacquard card and thus the corresponding Auxiliary needles in the working machine from their rest position into the working position be moved while the second knife box remains at rest. In the preparation of of Petinet patterns then z. B. the second knife box in action, and the jacquard sinkers selected from the jacquard card and thus the corresponding ones Auxiliary needles in the working machine remain in the rest position while Everyone the rest are moved into the working position. In this activity of the second knife box the first stays alone.

Through these known devices: e ?, it when using an ordinary Yes @. @ Quard device with only one knife boxW not possible, both types of pattern herzu = make when the individually movable auxiliary needles are either looking at the Chair pins and non-patterning on the cover pins or non-patterning on the chair pins and inspect the needles.

The present invention enables the manufacture of both types of patterns even when using an ordinary jacquard device with only one knife box made possible by the individually movable auxiliary needles, which patterning on the chair or Needles should act, from the lower rest position in a selection according to the pattern . be brought up in a manner known per se by lifting plates or the like, and if, on the other hand, they are not supposed to have a patterning effect on the chair or cover needles, all auxiliary needles are first in the upper position and then some of these auxiliary needles Transferred to the lower position in a selection according to the pattern. So it is according to the present invention to the combination of the elements known per se or - working methods of the auxiliary needles.

Instead of assuming a lower rest position of the auxiliary needles, the auxiliary needles can also assume an upper starting position. Shall the auxiliary needles do not have a pattern on the chair or cover needles, so the individual Auxiliary needles moved down in a selection according to the pattern. Shall inspecting the auxiliary needles act on the chair or cover needles, all auxiliary needles are off first brought the upper to the lower position and some of these. Auxiliary needles then Transferred from the lower to the upper position in accordance with the pattern.

Here, the knife box must, as described below, two strokes Execute `to select the auxiliary needles from the different starting positions" and: to be able to bring into the desired sample position.

The subject matter of the invention is shown schematically in the drawings.

Fig. I shows an embodiment of the subject matter of the invention in the first basic position.

Fig. 2 shows this embodiment in the first working position, which is also the second basic position.

Fig.3 shows the embodiment in the second working position. - Fig. Figure 4 shows another shape . of the means of movement for the auxiliary needles. In Fig. I i represents the chair needle, 2 the chair needle bar, 3 the lower part of the sinker head, ;;. 4 the sinker, 5 the knock-off comb, 6 the '- @ e # needle, 7 the deck rake, 8 the auxiliary @; tel and 9 the guide bed for the auxiliary j.rleIn.

'' "-` @ The auxiliary needle 8 is in the illustrated embodiment on the hub board io, which is in a guide bed ii in the direction of the arrow 12 can be moved back and forth. The guide bed i i forms with the guide bed 9 a rigid whole and can in a known manner by the lever 13 in the direction the arrow 14 moves up and down and by the train 15 by means of the lever 16 around the pivot point 17 can be pivoted. The hub plate io is provided with a recess; in which a rail 18 also moves back and forth in the direction of arrow 12 can be. The auxiliary needle 8 is i.9 by a spring attached to the foot 20 of the auxiliary needle 8 attacks, always pressed down on the hub plate io in a known manner. The lifting plate 1o has an inclined surface 21 and an inclined surface 22. An the end 23 of the lifting plate io engages the jacquard machine in a known manner the cord 24 on.

The operation of the device according to this embodiment is now the following: When working in front of smooth goods, all auxiliary needles are in the lower one Rest position (Fig. I). The loop-forming process takes place in the usual way Way off.

Should now e.g. Press samples are produced. where all the Auxiliary needles 8 have to be brought up, their associated chair needles i pattern, i.e. to be prevented from pressing by the auxiliary needles 8, so are in a known manner the corresponding lifting plates io through the jacquard machine brought so far to the left that the auxiliary needles standing on these lifting plates i o 8 climb up on the inclined surface 21 and reach the upper position (Fig. 2). The rail i8 must of course be so far ahead of the movement — the jacquard machine have been moved to the left that the lifting plates io for the movement through the Jacquara machine are released. If then the pull of the jacquard machine after completion the row in question ends again, the jacquard machine lift plates brought from the rest position (Fig. i) to the working position (Fig. 2) by the rail 18, which is moved independently, back to the rest position (Fig. i) brought back, Shall now z. B. -Petinet pattern are produced in which all those auxiliary needles 8 must be above, their associated Cover pins 6 do not pattern, d. H. thus prevented by the auxiliary needles 8 from the pattern formation are to be, according to the invention, all auxiliary needles 8 are first in the upper Rest position (Fig. Ä) brought. This is achieved in that all lift plates io brought so far to the left by a corresponding movement of the rail 18 be that the auxiliary needles 8 rise on the inclined surface 21 and so in the reach the upper position (Fig. 2). Then those Hubplatinen io, whose Auxiliary needles 8 should not prevent the corresponding cover needles 6 from patterning, pulled through the jacquard machine even further to the left by the knife box executes a larger stroke such that the corresponding auxiliary needles 8 on the Slide the inclined surface 22 of the lift plate io into the lower position (Fig. 3). Of course Here too, the rail 18 must continue further before the movement of the jacquard machine have gone left to the lift plates for movement through the jacquard machine to release.

After the mooring process has been completed, the lifting plates are returned to Starting position (Fig. I) brought back by the rail 18.

When several decking operations are in succession without any intermediary Press pattern production is expediently the lifting plates io from the working position according to Fig. 3 only transfer to the rest position according to Fig. 2 to avoid the unnecessary to save large movement of the lifting plates.

With the device described above, Petinet patterns can also be produced are, in which all the auxiliary needles 8 must be brought up, their corresponding cover pins 6 pattern, d. H. so the stitch from the corresponding chair needles i should lose weight.

Furthermore, with the device described above, press patterns be made, in which all those auxiliary needles 8 in the upper rest position must stand, the associated chair needles i do not pattern, d. H. so squeezed should be.

It is also easily possible to use lifting plates according to Fig. 4, in which an upper rest position is assumed and the auxiliary needles according to the pattern can be moved downwards and also upwards according to the pattern.

In general, it does not matter what means of moving the auxiliary needles be used.
