Abstract

A needle for laterally transferring or displacing a loop of yarn (t), especially for a circular knitting machine, has a slightly bent section closer to the tip that forms a curved section (2) running parallel to the needle body (1) and an L-shaped tongue (3) for transferring the loop. The tongue (3) is provided with an outer edge section (3 ') which is bent at right angles to form a surface parallel to the bent section (2), and with an upper edge section (4) which faces the outer bent edge section ( 3 ') is inclined. The needle is easy to manufacture and robust in operation and, since the needle body (1) can be constructed in one piece, it is also very smooth, so that the needle can move up and down without jerking.

Description

25th

The invention relates to a transfer needle according to the preamble of the patent claim.

From CH-PS 5 20 219 is a transfer needle for the lateral transfer of a stitch onto an adjacent one Known needle, in which a bent along a line running parallel to the N .'- ltlschaft Transfer surface is provided which faces an adjacent needle, the leading edge this transmission surface from the needle shaft is inclined starting in the direction of the rear end of the needle. The transfer area is within the im essentially U-shaped needle shank slidably guided, resulting in a straight structure of the needle shaft results. The latter has the consequence that the distance between the individual needles is small to keep, the width of which must be made correspondingly large, so that the diameter of the to be transmitted Mesh is also correspondingly large.

The latter not only results in a large-meshed product, but also the risk of a one-sided pull or tearing of the yarn to be processed.

The object of the invention is to provide a needle while avoiding the disadvantages inherent in the prior art to create that is inexpensive and robust and one stitch after the other without interruption in the side Can convert direction. This task is solved by the characteristics of the marking part of the Claim. This results in a transfer needle compared to the known embodiment the advantage of a much simpler structural design, which at the same time simplifies manufacture will. A compact arrangement is also made possible with the transmission needle according to the invention, so that a fine mesh product can be knitted. The size of the meshes to be transferred can thus be kept small in relation to the prior art.

Using the drawing, an exemplary embodiment is shown below of the invention described. It shows

F i g. 1 shows a front view of a transfer needle according to the invention:

2 shows a side view of a transfer needle according to FIG. 1;

F i g. 3 shows a view of the transfer needle Fig. 1, from behind;

4 shows a front view of several transmission needles according to FIG. 1 during a work process;

F i g. Figure 5 is a plan view of the needle assembly of Figure 4;

F i g. 6A to 6D are perspective views of the needle assembly during different positions in a Knitting process;

F i g. 7 is a side view of the entire needle.

A needle shaft 1 is shaped slightly to the right in the area facing the front needle end, that is to say the needle tip, namely angled, in order to form a parallel, stepped section 2. An L-shaped transfer surface 3 formed on it jumps from one edge of the recessed section 2 for transferring or relocating a mesh t with an outer, at right angles to form a bent part 3 'running parallel to the recessed section 2, with one on the right Angle to the section 2 bent and adjoining this part 3 "and with a front edge 4, which, starting from the needle shaft 1, is inclined in the direction of the rear needle end and thus also towards the part 3 '.

The needle also has a needle hook 6 holding the thread in place at the front end and a tongue 7. The reference numerals 8 and 9 denote needle feet and a needle cylinder, respectively.

The transfer needle according to the invention for the lateral displacement and transfer of a stitch t is designed as described above. One recognizes in FIG. 6A a loop which first from the transfer surface 3 and then, as soon as the hook 6 of the following needle shaft Γ has moved upwards within the transfer surface 3 for transfer (FIG. 6B), from the stepped section 2 and the inclined section Front edge 4 is held, the first needle shaft 1, as in F i g. 6C, j, i is moved down so that two stitches are held. At the moment when two stitches are held, the needle shaft 1 'with its stepped section 2 moves out of the area of the transfer surface 3. When the needle shaft Γ moves upwards, as can be seen in FIG. 6D, the transfer surface increases 3 open another stitch, and another stitch is transferred to the needle shaft 1 "by the similar movement of the subsequent needle shaft 1".

In the manner described above, loops are completely transferred before the knitting needle arrives and therefore the entire operation is extremely smooth with no sudden change in motion.

Due to the one-piece design of the transfer surface with the needle shaft, the inventive Transfer needle not only easy to manufacture and robust in its structure or construction, but it is also very smooth on the surface that comes into direct contact with the needle cylinder, with no bumps and indentations, as they would be in a welded joint, the stepped section 2 is therefore of particular importance and particularly preferable because it is ensured that the loop is securely held by the hook 6.
