Patented in the German Empire on August 9, 1910.

The invention relates to a method and an apparatus for producing Metal ring braid.

There are various methods and devices for making metal ring braid known by inserting wire screws into the last row of rings, but different the invention according to the new method and the device for exercising

ίο of the process in that in each case two side by side lying rings perpendicular to the row, the foremost turn of wire screws is screwed into the finished braid, whereupon the turns are cut off and joined at the same time in order to achieve the next turn after the braid is half a ring width sideways is moved to repeat the operation. The device ■ for producing the Braid consists in the fact that the wire is wound onto several rotating thread spindles, the top turn of the wire screws is guided through the blade of a knife against a stop and the foremost turn of the wire screw is pressed against the stop by means of springs and is held until the foremost wire turn is cut off by a counter knife and the cut end of the turn is advanced until both ring ends are in one plane.

It is achieved by the new method and the new device that a larger Amount is done in a cleaner and more even job than is the case with the known methods and machines is the case.

In the drawing is in FIGS. 1 to 10 the method and the device partially in view and section in the various Levels and details shown.

The wire 1 required for the metal ring braid winds (Fig. 2 and 8) on the threaded spindles 2 rotating by means of a gear drive towards the wire screw 3.

The toothed drive 14 of the threaded spindle 2, which is provided with bearing journals at both ends, is mounted between two metal plates 15 and 16. The toothed drive 14 is pierced in its axis and the one running in the metal plate 15 pin 14 ^ provided with thread, which runs in the nut thread cut in the plate 15, so that when rotated the toothed drive 14 moves up or down at the same time. In the bore of the spur drive 14, the threaded spindle 2 is inserted at the upper end and held by an adjusting screw. The upwardly moving threaded spindle 2 runs through a matching bore iy ^{a of} the plate 17. The plate 17, which is screwed onto the plate 16, also has a bore 18 on its end face which opens tangentially into the bore iy ^{a of} the plate 17. Above the plate 17 (FIG. 8) there is a horizontally rotating friction disc 20 which is fastened on the axis 19 and which is provided on its periphery with a soft rubber pad 20 ^a and runs pressed on the threaded spindle 2. the

^{■ Threaded axis 2 is stored again in a bore 2i a} of plate 21 so that it is held in its position when the disk 20 is pressed. The gear drive 14 is also driven from the axis 19 by means of the gear 22, and the operation is carried out as described below.

The wire 1 for the wire screw 3, which winds up in the threads of the threaded spindle 2, is inserted through the bore 18 of the plate 17. The movement of the gear 22 drives the gear 14, with it the threaded spindle 2. Simultaneously with the rotary movement of the threaded spindle 2, the threaded spindle 2 is axially advanced due to the threaded bearing of the pin 14 ″, and the spindle 2 is pressed against the threaded axis 2 by the friction disk 20 Wire 1 continues to wind up. After each single revolution of the threaded spindle, the toothed drive 14 is moved back in the opposite direction by the toothed wheel 22, with the threaded axis 2 again sliding axially downwards Wire screw 3 in connection with the rubber pad 2Z ^a to hold the friction disc 20 stationary and thus allow the threaded spindle 2 to run back one thread turn empty in the wire screw 3. The operations described above now alternate with one another, so that when the threaded spindle is buoyant 2 the wire 1 is drawn in and is wound up and when going back the threaded spindle 2 goes back empty for itself.

The wire screw first runs into the semicircular, not quite through hole 4 of the knife blade, 5, engages the inclined plane 6 lying above the hole, the slope of which corresponds to that of the wire screw, and goes at the highest point of the inclined plane 6 after it goes under the projection 7 runs out again, with a further quarter turn through a ring a ^{1 of} the curtain braid (Fig. 5) and after another half turn through the. the first next second ring a ³ and finally after the last quarter turn over the projection 7 against the stop 8 ^{1 of} the slide 8, to which the winding i rests, whereupon the wire screw stops. By means of the slide 9, which then moves downwards and in which the compression springs 10 are inserted, the foremost turn i is pressed onto the projection 7 by the spring 10 and held. Then a counter knife 11, which runs on the side surface (Fig. 2, 4 and 5) of the knife blade 5, shears the foremost turn of the wire screw 3 at the acute-angled edge 7 ^{1 of} the projection 7 in the direction of the arrow (Fig. 2). Furthermore, the sheared end i ¹ is pushed further by the counter knife until both ring ends i, i ^{1 are} joined lying in one plane. After the joint, the suspended link is ready. The counter knife 11 goes back to its previous position. Likewise, slide 9 together with compression springs 10 and slide 8 with stop 8 ¹ return to their original position and release the finished link or links for the next wire windings to be hooked in, and the operation is repeated after the already finished mesh, such as is set as described below.

The braid, as it is produced in rows by the device in a horizontal position, is shown in FIG. In the row of links α ¹ , α ³ , α ⁵ , α ⁷ , β ⁹ , α ¹¹ and α ¹³ are ζ. B. in the first operation of the device, the links a ¹ , a ^s , α ⁹ and a ^{13 are} attached. After these links have been drawn in, the frame 12 is moved laterally in the direction of the rows of links so that the openings formed between the aforementioned links lie in front of the wire screws 3, whereupon the links a ³ , a ¹ and a ^{11 are} drawn in during the next operation of the device will. This series is now complete. The finished piece of braid '. is preferred so that the last row of rings hangs in the correct position in the knife blades (Fig. 1 and 5).

In the following row, the new links to the links a ¹ to β ¹³ drawn in last are offset by half a ring width, so that the links a ² , a ¹ , a ⁶ , a ⁸ , a ¹⁰ , a ¹² and a ^li between the previous ones come to hang.

The frame 12 is therefore shifted by half a ring width so that the links a ¹ , a ^e , a ¹⁰ and a ^u can be hung; then the frame 12 goes sideways again as in the previous row, so that the intermediate links α ⁴ , α ⁸ and β ^{12 are} attached in the next operation.

The knives are straight, like the metal ring braid in ribbon or circular shape Direction (Fig. 4) or arranged in a circle (Fig. 9 and 10).

As can be seen from FIGS. 1, 4 and 5, the knife blades 5 also serve to guide the wire screws 3, and this guide part 6 is set back against the main body 5; the radius of the curve 5 ¹ corresponds to that of the bore 4.
