Definitions

  • the present invention refers to a knitting device and method for preparing batting as used for linings, etc, reinforced with knitting stitches, said batting being prepared directly from raw material as it comes out from th carding machine. knitting device and method for the production of a reinforced batting which can be easily handled without being shredded, torn or distended, thus effecting a saving in machinery and labor as well.
  • the knitting device which binds and reinforces the batting according to the invention is applied particularly to the Raschel type batting making machine, which makes batting from spun and knitted threads, by replacing the present knitting system and using ordinary cotton thread for knitting through the batting.
  • This device may in fact be fitted to a specially built machine or to one adapted to this purpose.
  • the sheet of loose material as it comes from the carding machine in the desired thickness is passed over a set of knitting needles with single hooks, these needles having an individual rotating movement and collective ascending and de scending movement, which knitting needles during their descending movement grasp the threads situated above the loose material, these threads having such a movement as to cause each individual thread to encircle alternatively one hooked needle and the next one, so that each thread may alternatively twist around two adjacent needles, the hooked needles during their ascending movement having their hooks turned in the direction from where comes the sheet of loose material, while during their descent they are turned in the opposite direction, the hooked needles rotating through 180, the rotation of the needles being effected by means of twisted portions of the needle shafts, which twisted parts pass through the teeth of a comb having a vertical movement and through a part supporting the needles, which part has a vertical movement in order to raise and lower the needles, the movement of the comb and that of the part supporting the needles being of the knitting device

  • FIG. 10 shows a piece of reinforced batting as it looks on its upper face where the knitting work appears like plain broken lines disposed along the chain of loops, while Fig. 11 show th under face of the sheet represented in Fig. 10 and it may be seen how the knitting work has the shape of chain loops disposed in a broken line along the loop chain as well as the manner in which the loops of adjoining chain rows interlock mutually.
  • Figs. 12, 13 and 14 show the manner of work of the knitting needles in conjunction with the knitting threads.
  • Figs. 12 is shown the hook of the needle in the plate for the guiding of hooks at the moment the work begins or the hooked needle has descended pulling with it the chain loop
  • Fig. 13 shows how the thread is twisted around the raised needle in order to prepare the next loop
  • Fig. 14 shows diagrammatically the course swinging to th right and to th left followed by the thread in order to twist alternatively around the adjoining needles.
  • the knitting needles I are free parts similar to the plain crocheting needles, each needle'having a housing 2 in which it can move and which is located in a supporting and guiding part 3, 31, 4 consisting of three pieces connected together with screws. Parts 3, 31 leave between them a groove 5 in which is inserted a wedge or fixing part 6 which goes through the necks 1 of needles I, so that once the needles have been placed into the said supporting part they stay there and can no longer move except for rotating.
  • the rotation of the needles is effected by passing shaft 8 of same through the parallel teeth 9 of a comb II], which teeth when the lower end part I I twisted for 180 passes through them cause hooks I2 of needles 1 to rotate for 180.
  • the guiding part 3, 31, 4 is provided with as many channels 2 as there are needles I, according to the width of operation of the machine. It is attached by means of angle iron I3 on two sliding rods M, which rods travel in the bearings I 5 secured on frame III of the Raschel machine. On rods I4 are also fixed small wheels I6 which are operated by lever arms I I fitted to the Raschel machine, which arms are set in motion at the convenient moment by some cams of the Raschel machine (the end of the levers II only are shown in the drawings), pushing upwards small wheels I6 so that the guiding part bearing needles I is also lifted. The downward movement of rods I4 is limited'by the descent of arms II which are acted upon by the weight of the parts mounted on rods I4.
  • Comb I! is borne by arms I8 secured on rods I9 which travel in bearings 20 firmly attached on rods I 4.
  • rods I9 At the lower end of each rod I9 is located a small wheel 2
  • Shaft 23 is supported by bearings 25 which are attached in some known manner on rods I4 at their lower ends.
  • the ends provided with hooks I2 of needles I are located when at rest in holes 26 of a guiding bridge 261 over which bridge passes also the sheet of loose material during the work.
  • the guiding bridge is secured on the Raschel machine frame by supporting corners I51 or the like which are fastened on said frame by means of screws I53, while said bridge is placed under the thread guides 21, whose number is higher by one unit than the number of needles I, as usual.
  • the guides 21 guide threads 28 the work distributing the threads among the needles I.
  • each of the guides 27 perform an encircling movement over and around a needle I each causing the thread 28 to twist around the corresponding needle while the needles remain lifted above the guiding plate 261 (Figs.
  • Each thread 28 is first twisted around a needle I (Fig. 14), then the loop is formed, afterwards it is twisted around an adjacent needle I1, a loop is formed here again, the third time it is twisted anew around needle I, the fourth time again around the adjacent needle I 1, and so on, thus linking with each new loop the chain of loops made by one needle with the chain of loops made by the adjacent needle in such manner as the chains are interconnected.
  • This movement is shown diagrammatically in Fig. 14.
  • the thread starts from point a, encircles needle I, arrives in b and stops for a moment, after which it starts again and arrives to its starting point a.
  • Fig. 11 is shown how the chain of loops 29 made by needle I is locked with the chain of loops 291 made by the adjacent needle I1, the chain of loops 291 with the loops 292 made by the adjacent needle I2, and so on.
  • Threads 28 are brought and passed through guides 21, the ends 281, of the threads being 'made into a bundle and tied on to the drum (not shown in the drawing) which receives as usual the finished product.
  • the sheet of loose material 29 as it comes from the carding machine is brought and placed over the guiding plate 261.
  • the machine is turned by hand until the hooks I2 lifted by arms I I pushed by the corresponding cams come through the sheet of material 29 and then with a hat of any description the sheet is pounded down on the plate at the points where it has been lifted by the hooks when going up through it.
  • the threads 28 twist around needles I, I1, I2 respectively, following the course indicated in Figs. 13 and 14.
  • cam 22 is brought in a position to push small wheels 2
  • the rotation movement is now stopped and over the threads 28 is passed a head string 33 in front of needles I, so that when the next loops are made it prevents the sheet from being lifted.
  • the machine is again set in motion, the corresponding cams let arms I! free which now by their descent cause hooks I2 at present turned towards the running direction of the sheet of material 29 to catch the threads, to pull them down thus forming the loops of the chains and to retract into the holes 26 of the guiding plate, without catching sheet 29 also.
  • cams 22 having also rotated comb I0 begins to descend until at the moment the needles have reached the end of their downward stroke their twisted portions II get between the teeth 9 of the comb thus forcing the needles to rotate for 180 in order to revert to their initial position, that is with the hooks turned in the direction from where comes sheet 29 (Fig. 12).
  • the guiding plate 261 is adjustable in height to suit the kind of knitting work and in order to vary the pressure of the loops on the material of the sheet to be worked on.
  • the supporting corners of plate 26 are provided with slots I52 through which the fastening screws extend.
  • the twisted sections II which cause needles I to rotate when they pass between the teeth of comb ll! may be replaced through helical grooves 3
  • This part guides the shaft of the needle at its lower end where is located the groove 3
  • Another adequate method to cause the rotation of the needles for 180 would be, for instance, to provide the shafts of the needles in a convenient point with teeth 34 which would mesh with the teeth of a rack 35 (Figs. 8a, b) which may be displaced both ways transversely to the shafts of the needles by any known mechanical or conventional means, for a determined distance sufficient for rotating the needles for 180.
  • the knitting device according to the present invention may be used also for knitting various patterns on any fabric, cloth, etc. when ready woven, in order to adorn their aspect or mark them with various distinctive trade signs, etc.
  • This knitting device can also produce knitted cloth which may be used for various works in the underwear and garment industry, etc. in the usually known manner.
  • a device for knitting reinforced batting as used for linings, etc. comprising a set of knitting needles with single catching hooks lodged in a supporting-guiding part which forces these needles to ascend and descend all at the same time, a toothed comb, said needles during their ascending and descending movement passing their lower ends through the teeth of said comb for an individual rotation through 180", the knitting needles being also provided at their lower ends with shafts having a section twisted through ing guiding part effective to force said needles to ascend and descend all at the same time, each needle having a shank at the lower part thereof, a supporting guide member for causing rotation of the needles through provided with means for guiding and engaging with the shank at the lower part of each needle, means having a helical portion upon the shank of each needle engaged by the means upon said supporting guide member and effective to cooperate therewith to cause the mentioned rotation through 180 of the needle shank and hook upon the needle in each case.
  • a device for knitting loose batting made from a sheet of loose material as it comes from the carding machine, used for lining and the like, applicable to the Raschel batting-making machine comprising a set of knitting needles with single catching hooks lodged in a supporting guiding part effective to force said needles to ascend and descend all at the same time, each needle having a shank at the lower part thereof, a supporting guide member for causing rotation of the needles through 180, engagement means for engaging with the shanks of the needles, means upon the shank of each needle for engaging with said engagement means and effective to cooperate therewith to cause rotation of each shank through 180 and therewith alsosimultaneously rotation of the hook of each needle.
