Raschel machine. Patented in the German Empire on April 16, 1904.

The Raschel machine or the safety chain chair is known to be used for the production of smooth chain goods, e.g. B. plush, crepe, sheet metal materials, fringes and the like. And has one or two rows of needles with latch needles. The hand or swivel chain chair is used to produce patterned chain goods, Pineapple and the like. Since the two substances differ at times, the one more, the one

ίο others are asked less, so it will be felt as a disadvantage that both types of fabric can not be made on a single machine, all the more so than both different types of machines take up a relatively large space to theirs Need to be set up. Since now alternating pressed goods and Raschel goods are a matter of fashion, thus one type of machine is usually idle while the other is in motion.

The present invention aims to make the previous Raschel machines also suitable for the production of pressed goods, whereby the advantage is achieved that the perforated needles can be retained, the production of multiple patterns is made possible, and that with the replacement of the latch needles of the Raschel machine by pointed needles for the Raschel machine changed into a mechanical chain chair also different three or four sample sheets can be used, also that the Raschel machine enables faster work due to the upright arrangement of the needles.
In order to be able to produce pressed goods, patterned chain goods, pineapples and the like on the Raschel machine, the same must be modified as follows.

The one rear latch needle bar is with its linkage and eccentric from the Machine removed, as well as the milling sheet; the remaining latch needle bar is replaced by a hook needle bar. The milling sheet for making smooth Chain goods are sold through a discount. Sink comb replaced, and to close of the hook needles is placed on the front of the machine the press.

In the drawings, Fig. 1 illustrates a rear view of the machine when it is modified for the production of press ware. Fig. 2 shows a cross section according to AB (Fig. 1). 3 to 5 show details of the modified machine in its device for the production of pressed goods. Figures 6 and 7 illustrate the. Machine set up for the production of Raschelware.

The Raschel machine (Figs. 6 and 7) is known to have one or two latch needle bars 25 with the intervening milling sheets 26 and the perforated needles 24. The Latch needle bars are set into action by the eccentrics 5 on the shaft 6, by rollers 1 at the free ends of the pivot 2 rotatable lever 3 on the eccentrics 5 run and alternately raise and lower the latch needle bars with their latch needles over the milling sheet. The milling sheet knocks off the stitches formed by the latch needles.

This well-known Raschel machine is now supposed to be used as a mechanical chain chair for production act of pressed goods, the rear needle bar is removed with its latch needles, the now existing single Zungennädelbarre thereby into a hook needle bar transformed that a bar provided with hook needles is screwed onto its support

Claims (1)

will; the milling plates 26 are also removed. So that a loop formation now take place can, a sinker comb 13 must be arranged, as well as a press 16 for Closing the hook needles. For this purpose, two shafts 7 and 8 between the Side frames of the machine used, of which shaft 7 for moving the. Sinker comb 13 and shaft 8 are used to move the press 16. The shaft 7 · carries in the Middle of its length a lever 9, which with its role io on one on the Shaft 6 attached thumb 11 runs. Also located on the ends of the Shaft 7 each have a lever 12 and these are attached to the sinker comb 13. It will so the sinker comb 13 through this Ein ^ direction and by means of the same retracting spring 14 in a forward and backward movement offset. The press 16 is slidable on it '' and exchangeable sample sheets 17 provided and seated on levers 18 which are rotated by the shaft 8 from. This pre- and backward movement of the press 16 is effected by the thumb 19 and thereby achieved that 8 levers 20 are firmly connected to the shaft, which rollers 21 wear that slide on the thumb 19. Springs 22, one end of which by an am Machine frame attached support is held, have the endeavor to keep the rollers 21 to use the thumb 19. As a result, after the thumb stroke, the Press 16 always returned to its original position. The sinker comb 13 and the press 16 are respectively at their lever ends 12. 18 articulated, as FIGS. 3 and 5 show. The Raschel machine thus modified to a mechanical chain chair has the following Operation: The drive 23 of the machine moves the thumb 5 and in a known manner first lifts the hook needle bar halfway up; the needles 24 of the Raschel machine put the threads on the hooks of the needles 15; the needle bar 4 then rises up to the full stroke of the thumb 5 in the air, whereby the placed around the needles Threads under respectively. be brought behind the hooks of the needles. Now will on the part of the thumb 19, the press 16 is put into action and fastened thereon displaceable sample sheets 17 close the hooks of the needles in a corresponding manner 15 (see Fig. 4). Finally, the sinker comb 13 is secured with the aid of the thumb 11 pushed forward, and the previously formed stitches are over the closed ones The hooks of the needles are knocked off and the press goes back at the appropriate moment. Then the needle bar 4 goes down and the sinker comb 13 into its original position back; the stitch formation is finished. Should the machine be used again as a Raschel machine for the production of smooth chain goods work, it is modified as follows: You remove the shafts 7 and 8 together with their lever rods 12 and 18, 9 and the Sinker comb 13 and press 16. Then you screw the hook needle bar 4 with the Hook needles 15, sets the milling sheet 26, which is provided with supports 27, and er \ sets the previously removed hook needle bar through the latch needle bar. Should with two latch needle bars are worked, the rear latch needle bar is also placed one that can be moved by the second thumb 5 acting on the second lever 3. You also set a second milling sheet. ■ The above-described device for the production of warp goods enables one Abundant pattern generation, since you can use six needle groups 24 and three or four independent pattern sheets can work. As can be seen from the above, the modification requires the Raschel machine to a chain chair and vice versa little time. Patent-A ν saying: Raschel machine with two latch needle bars, characterized in that they through conversion for the production of single-surface patterned warp knitted fabrics is made suitable that after removal of the rear latch needle bar the front latch needle bar by a Replaced the needle bar and a press (16) at the front of the machine with sample sheets (17) and on the back a special sinker comb (13) is arranged, which are moved by eccentrics that after lifting the Needle bar at half the lift height, the machine needles, the threads on the point needles place, with full stroke of the needle bar bring the threads under the tips, then the press with the sample sheets presses the needles, the sinker comb with its sinkers applies the stitches and tees off and then all parts are returned to their starting position. 1 sheet of drawings.
