The invention relates to an edging machine for producing one of two simple edge knitted goods composite edges knitted goods, whereby the individual goods are simultaneously produced on the knitting chair and entwined with one another.

The essential feature of the invention is that on each of the two needle carriers of the knitting chair two groups of specially driven needles are provided so work together with the thread guides that each through a group of both needle carriers one edge knitted fabric and the second with the other two needle groups the first tangled edge knitted fabric is produced.

An embodiment of the invention is illustrated in the drawings.

Fig. Ι is a vertical sectional view through a knitting chair manufactured according to the invention.

Figure 2 is a plan view of a portion of the needle disc.

Fig. 3 is a view showing the two locks that are used to move the Maschinenbzw. Serve disc needles.

Figure 4 is a similar view of those used to move the chair or cylinder needles Locks.

Fig. 5 shows a piece of composite edging knitted fabric made according to fig Invention can be made. However, these goods do not form part of the present invention.

6 and 7 are diagrams from which it can be seen in which way the Meshes of one of the goods are stretched at the same point where the meshes of the other goods are removed.

The subject of the invention can be used with machines of smaller diameter with only each two locks for the machine and chair needles are used as well as large ones Machines with more than two locks for each needle carrier. A machine of the latter Kind is shown on the drawings.

To better illustrate how the machine and chair needles work together, are the locks for the machine needles following a straight line rather than circular in Fig. 3, arranged. So is the chair needle lock cylinder handled in one plane.

With a running machine, the lengthways dimensions of the chair needle locks are somewhat different from those shown in Figure 3 because of the radial arrangement of the machine needles; however, as far as the size of the forward and backward movement of the needles is concerned, so the locks shown act in the same way as those of a running machine.

In Fig. Ι 1 denotes the needle cylinder,

which is provided with vertical grooves for receiving and guiding the needles and suitable Way is connected to the machine needle bed. The lock cylinder 3 is arranged around the needle cylinder, on its inner surface the locks are attached, which serve to give the cylinder needles a and backward movement. The lock cylinder sits on a rotatable ring. 2, which is driven in any way. The needle disk 4 is seated on an axis 5 and, with reference to the needle cylinder 1 held in a fixed position, e.g. B. by lugs 6 arranged on the disk and cylinder 15. and 7 (Fig. 1), respectively. The lock washer 9 is arranged above the needle disk, on its lower surface the locks are seated through which the machine needles move back and forth obtain. The needles are guided in radial grooves provided on the surface of the needle disk. The rotation of the Lock washer in accordance with the lock cylinder can be on any suitable Way. Instead of driving the locks, the needle disc and the needle cylinder could also be used are set in rotation, the locks then of course being arranged in a fixed manner have to. The invention can also with so-called flat knitting machines with back and forth her going lock slide application. The needle cylinder and needle disk are both equipped with two groups of needles, whereby the needles of one group with respect to those of the other according to the one to be manufactured Edge knitted fabrics are arranged. The round-edged knitting machine shown is suitable for the production of so-called ι and ι knitted edges. The stitches are drawn out successively through a cylinder needle and a disc needle, a needle χ of a cylinder needle group always alternating with a needle x ^{1 of} a disc needle group, and the needle group x, x ¹ with the needle groups y, y ¹ . If a so-called 2 and 2-edged knitted fabric is to be produced, the needles change in pairs instead of individually. Other types of knitwear also require another Corresponding arrangement of the needles in the two needle carriers. The disc needles x ¹ lie in one plane with the cylinder needles y and the disc needles y ¹ in one plane with the cylinder needles x. The needles x, x ¹ work together with one or more thread guides w (Fig. 1) for the production of an ordinary knitted fabric. Likewise, the needles y, y ^1, in conjunction with one or more thread guides ν, produce a second knitted fabric, the needle loops of which are arranged between those of the first knitted fabric. So z. B., as can be seen from Fig. 5, the needle loops x ² by the needles x, x ¹ made of one yarn and the needle loops y ² by the needles y, y ¹ made of another yarn. So that the needles x, x ¹ and y, y ¹ can work independently of one another, they are of different lengths, in that the plane in which the feet of the needles χ lie is different from that in which the feet of the needles y are arranged are. The same applies to the needles y ¹ , x ¹ , as can be seen from FIGS. 3 and 4. The arrows in these figures indicate the direction of movement of the locks with respect to the needles. Any lock system can be used to move the needles back and forth. Advantageously, however, was found to x with the needles, α x ¹ retreating lock pieces α ¹ lock pieces b to use b ^1, y in the manner of the needles, y ¹ at the same position act that the needles y, y ¹ are withdrawn while the thread is being laid on needles x, x ¹ . In the same way, the cam pieces d, d ^{1 are used} to retract the needles x, x ¹ , while the thread is culated on the needles y, y ¹ by the cam pieces c, c ^1. Such an arrangement is shown schematically in FIGS. From the same it can be seen how the retraction of the needle y, y ¹ takes place under the action of the lock pieces b, b ¹ when the thread is kulated through the needles x, x ¹ under the action of the lock pieces a, a ^1. These figures can also see how the lock pieces d, d ^1, the needles x, x ¹ retreat if the stitches on the needles y, y ¹ under the action of the lock pieces c, c is sunk. ¹ In a knitting chair produced according to the invention, the chair and machine needles can also be arranged differently instead of being arranged in one plane, without thereby losing all of the advantages offered by the subject matter of the invention. The needle disc offers plenty of space to form all guide grooves for the machine needles, since only the outer edge needs to be grooved for all needles, while the inner part is only grooved for the longer needles. To facilitate the grooves of the disc, the grooves on a detachable from the disc ring / \ ^a may be provided. . Godfather ν ϊ-Αν Proverbs: i. Knitting machine for the production of edge knitted goods, characterized in that, that each of the two needle carriers with two separately driven needle groups is provided, which in such a way with their thread guides work together that each needle group of a needle carrier a knitted edge fabric and using the other two needle groups, a second knitted edging fabric intertwined with the first is produced will. 2. Knitting machine according to claim i, characterized in that the needles one Group of one needle carrier with those of a group of the other needle carrier in stand on one level. 3. Knitting machine according to claim 1, characterized in that the lock pieces are designed such that the needles forming the stitches of a knitted fabric to be withdrawn from the point at which the thread touches the other knitted fabric forming needles. 4. Knitting machine according to claim 1, characterized characterized in that each needle carrier groups of needles of different lengths and the needle lengths are arranged accordingly Has locks, the needles of one group of each needle carrier are longer than those of the other group and the drive locks are arranged in different planes corresponding to the lengths of the needles. 1 sheet of drawings.
