Description

Fixed knitted fabric The invention relates to a fixed knit Weft knitted fabrics, drawn out in the sinker stitches and as needle stitches to the neighboring ones Wales are hanged.

It is already known to use extended sinker meshes as intermediate meshes to be inserted into the adjacent wales. One worked in such a way However, goods are only relatively mesh-proof. It will be the mesh running in one Direction prevented, but not in the opposite direction. That's what the Number of stitches in individual wales or all wales kept greater than that Number of rows worked. This is particularly detrimental if the drawn sinker stitches extend over several courses, because as a result, the knitted fabric is easily pulled together in such a way that the occurring Tensile forces only or mainly claim the mentioned sinker meshes and they are therefore exposed to an increased risk of damage. The latter Goods also have defects in which the drawn sinker meshes on the the second next stitch of an adjacent wale are attached. Also one such goods are only mesh-proof in one direction. It is also already known the gaps that arise when expanding a piece of goods by covering meshes to conclude in the goods that on the by hanging a needle stitch chair needle that has become free is hung on the adjacent sinker mesh. As a result the aforementioned purpose, however, remained the known use, the sinker mesh limited to a few peripheral areas of the goods. It remained unknown here that one the sinker meshes in a different context systematically to the greatest possible extent can apply to achieve a inaschproof product without expanding the latter to have to. The latter requirement, however, corresponds to a knitted fabric that. on a circular knitting machine is made with latch needles and bayonet plates, the ones to be imposed Sinker mesh by means of the bent ends of the bayonet sinkers on the neighboring ones Needles are hung so that there are short interstices, the loop knots form and thereby a locked commodity -, - just. But this has the disadvantage that it is quite inelastic. In addition, it cannot be achieved by known means Manufacture on flat weft knitting machines.

Uni to avoid the discussed 'disadvantages of the known knitwear and to achieve a fabric that is strong and elastic in both directions according to the invention those needle stitches in the area of which the drawn platinum stitches are hung, overhanging the neighboring wales, so two at a time Needle stitches brought together. Reaches a ladder in such a product Area of an extended sinker hole, the continuation of the Tied stitches.

Around the chair needles that were freed from overhanging Masehen reliably in the area of the needle stitches next to the overhanging during the covering process Bringing sinker meshes located is further according to the invention The push-off device acting on the chair needle shafts is used, or the relevant ones are used Chair needles on a special, separate and special from the main needle bar movable auxiliary needle bar attached and through these needle needles to be aimed Sinker mesh detected. Up to now the was used to pull out the sinker meshes Decking machine or needle-like arrangement, but only unsafe hold the sinker stitches while working a row of stitches. With knitting machines you also have needles or sinkers of a special kind to grasp the sinker meshes used, but they cannot be used in flat weft knitting machines.

The drawing illustrates an embodiment of the subject matter of the invention. Fig. I is a stitch pattern of the manufactured goods. Fig. 2 shows the adjustment a chair needle that has to accommodate a circuit board pocket to be pulled out.

Fig. 3 is the side view of a longitudinally divided chair needle bar after pulling the auxiliary needle bar.

Fig. 4 is the floor plan for Fig. 3.

In the row of stitches 2 following the smooth row of stitches i, certain stitches 3 are hung over the adjacent wales. In addition to the stitches 3 , the sinker stitches -t are pulled out and placed on the needles that have become free due to the overhanging, so that a wale 5 is connected to this sinker stitches.1. After another smooth row of stitches has been worked, the stitches 6 are hung over in the next row of stitches and the sinker stitches 7 adjacent to them are brought onto the needles that have become free as a result of the overhanging. This process is repeated several times below, the overhanging not taking place to the left, but to the right.

By pulling out the sinker meshes 4 and 7 , the openings otherwise formed by the overhanging meshes 3 and 6 are closed in a manner known per se, so that the goods make a closed impression.

Moreover, it is by no means necessary that the sinker meshes should be pulled out takes place in the same direction as the overlapping of the adjacent needle stitches. If desired, the extended sinker meshes can overhang the neighboring ones Cross needle stitches in a manner known per se, but in such a way that the sinker stitches each to be hung on the chair pins that have become free and no breakthroughs of the goods. However, there are accumulations of threads at the points concerned created. The goods shown in the drawing resemble smooth goods.

The goods described can be manufactured in many ways. The easiest way is to use a device through which those chair needles of each of which sinker meshes are to be included, so in the direction of the finished goods are pressed towards that these chair needles when going up in can pierce the respective sinker meshes. This must be done during the mating process take place, because of the overhanging of certain stitches, the neighboring sinker loops be pulled sideways and thereby into the area of the pushed back chair needles reach.

So if the needle mesh 3 is hung over from the chair needle io by means of a cover needle on the stool needle i i in a manner known per se, the chair needle bar is lowered into the striking position and then the chair needle io is brought out of the row of adjacent needles to the point io '. Here it is to be moved obliquely to the longitudinal axis of the chair needle bar in the manner shown in the drawing according to the arrow 1: 2 in order to get reliably behind the sinker mesh 4 to be pulled out.

The specified adjustment of the chair needle io can be different Way. The easiest way, as already mentioned, is to use a push-off device13, which only acts on the stool needle mentioned, but does not affect the neighboring needles lets to push out of the row of other chair needles in the direction of arrow 12.

Instead, as well as according to the fig. 3 and 4, a longitudinally split chair needle bar are used per se known type, all the chair needles io, have to take the sinker loops, to an auxiliary needle bar 14 and all the other chair needles, particularly those ii, to the particular - Needle bars are to be overhanged, to which the main needle bar 1 5 are attached. After overhanging the stitches 3 and lowering the needle bar 14,15, the auxiliary needle bar 14 is pulled forward and adjusted laterally by means of a finger 16 so that the chair needle io gets into the position io 'shown in Fig. 2 with the neighboring needles and the sinker mesh to be pulled out 4 reliably detected during the following rise. When this has been done, the auxiliary needle bar 14 is brought back into the working position for the main needle bar 15, whereupon the machine continues to work in the usual manner.

Instead of the needles in the direction of the platinum noses to be picked up by them to move towards, one could also vice versa the latter meshes by means of an auxiliary rake and lift them into the area of the stool needles concerned by the auxiliary rake the respective sinker meshes when working the next row of stitches offset by one or more needle pitches and then brought onto the relevant needles.
