Definitions
- the invention relates to a method for preparing stockings made on circular knitting machines for sewing together or linking the tips in a linking machine which has a chain conveyor.
- the invention further relates to a conveyor for linking machines in which the tips of the stockings prepared according to the method are closed.
- the quality of the seam varies greatly depending on the fabric on which it is carried out; it is best for wool and acrylic stockings, less good for cotton stockings. Furthermore, the seam is larger because it was not only carried out on the rows of elastic thread, but also on the wide row reinforced with two threads.
- the known system explained above uses a special construction of the conveyor with which the linking machines are equipped, in which the tips of the stockings prepared as previously explained are closed.
- the construction is made possible by the fact that through the development of the hosiery conveyors with chains, the thickness of the bars increased from an initial 4 mm to 8 mm and even 9 mm.
- the invention has for its object to provide a method for preparing stockings made on circular knitting machines for closing the tips in chain machines with chain conveyors, in which the disadvantages of the prior art are avoided.
- a better alignment of the stocking should be achieved, especially in the corners, so that a practically perfect, straight seam can be produced.
- the seam should also be thinner and extremely secure. After all, this seam should have a visible and tangible alignment with the excellent conventional stitching point by point.
- the row of wide stitches follows a row of narrow stitches, which was made with the same yarn as the stocking.
- This measure has the advantage that a reinforcement is obtained in the area of the row of narrow stitches compared to the following row with wide stitches.
- the conveyor provided for solving the above object with the features in the preamble of claim 5 solves the above object in that the thickness of the guide ribs is less than the height of the wide stitches which are formed at the end of the stocking tip.
- the rib thickness is preferably between 0.5 and 0.8 mm.
- the mutually opposite debris of the two toothed chains of the conveyor are pressed by springs in the direction of the longitudinal center plane of the conveyor.
- the two layers of the stocking can be positioned more precisely when it is inserted into the gap that separates the first portions of the guide ribs that protrude from the rods towards the median plane, because the fabric has the possibility of coming off to better adapt to both sides.
- the measure of claim 8 has the advantage that the fine-meshed rows of elastic yarn are always slightly stretched, whereby the small difference in height between the fine-meshed rows on the side of the decreasing tip and the fine-meshed rows in the heel area is compensated.
- FIG. 1 shows the view of a stocking in the region of its tip, which is prepared according to the invention for sewing on a warping machine which has a chain conveyor,
- FIG. 2 shows a schematically illustrative representation in the sectional plane II-II of FIG. 1,
- FIG. 3 shows the perspective view of a chain conveyor when feeding the tip of a stocking prepared according to the invention to a linking machine
- FIG. 4 shows a sectional illustration in the plane IV-IV of FIG. 3
- FIG. 5 is a sectional view similar to FIG. 4, showing the stocking shortly before leaving the chain conveyor,
- FIG. 6 shows a sectional illustration in the plane VI-VI of FIG. 4,
- Figure 7 is a sectional view in the plane VII-VII of Figure 5 and
- Figure 8 is an exploded view of the rod indicated by arrow VIII in Figure 3.
- a course 3 with very tight stitches is produced, on which a course 4 is made wide stitches follows, which in turn are followed by a few small rows 5, for example four or five rows of narrow stitches made of elastic yarn.
- a further 10 to 12 courses are made with a yarn that is stronger than the yarn of the stocking, based on a known, normal manufacturing process, so that a reinforced or widened edge 6 is formed, which has the task of the stocking to position on the conveyor of the warping machine. If one looks at the thickness of the stocking in FIG.
- the conveyor for supplying the stocking prepared according to the invention to the linking machine has, in a manner known per se, two rods 7 and 7 'which are mirror-symmetrical to the longitudinal center plane of the conveyor and are separated from one another by a slot 8.
- the width of this slot 8 is dimensioned such that when the layers lying one on top of the other in the area of the top of the stocking are pushed manually into the inlet 9 (FIG. 3) of the conveyor, the reinforced edges 6 on the adjacent edge sections of the upper sides of the bars 7 and 7 '(see also FIG. 6).
- the reinforced edges 6 are gripped by two toothed chains 10 and 10 of the conveyor, whereby the toe is automatically moved towards the exit of the conveyor.
- the opposite sides of the rods 7 and 7 ' are designed such that, as shown in FIG. 5, they have rib sections 11 and II 1, respectively, which run obliquely downwards and are separated from one another by a slot whose width is smaller than the thickness of the two layers of row 3 lying on top of each other with the very narrow stitches, followed by the wide row of stitches 4.
- the inclined sections 11 and 11 'of the ribs merge into horizontal sections 12 and 12', the undersides of which run parallel to the upper sides of the rods 7 and 7 'and are at a distance from these upper sides which is somewhat smaller than the sum of the height of the wide ones Row of stitches 4 and the fine rows of stitches 5 in the tensioned state.
- this sum is 7 to 8 mm.
- the thickness of the ribs of the two sections 11, 11 'and 12, 12 * is in turn smaller than the height of the row 4 stitches with wide stitches and amounts to only 0.5 to 0.8 mm.
- the mutually opposite debris 14, 14 'of the toothed chains 10, 10' are spring-loaded according to FIG. 7, specifically via strips 15, 15 ', on which small springs 16, 16' act, which are attached to the rods 7, 7 • Covers 17, 17 • are housed.
- This solution of the double spring load allows a more precise positioning of the two layers of the top of the stocking when the wide row of stitches 4 enters the slot which separates the oblique rib sections 11, 11 'from each other, which on the opposite walls of the two rods 7 and 1 ⁇ are trained, because the fabric has the opportunity to adapt better on both sides.
- the increase in the thickness of the stocking, which rests on the ribs in order to tension the fine courses 5, can be achieved in that there is a row with reinforced loops in front of row 4 with wide loops or in that the stocking made of double yarn and the row 4 with wide stitches consist of just a single yarn.
- the flexibility of the slats 16 and 16 'could be adjustable by means of suitable stops with screws in order to adapt to the stocking to be sewn.
