Definitions

  • the presentinvention relates to machines for the manufacture lof tubular cords or braids, and to methods for producing cords twisted in theopposite direction to the knit- .t1ng. y
  • the tubular kitted cord or braid issuing from the ma.- chine is a cord in which the thread forms coils having a small pitch and which will be hereinafterdesignated as a cord with closed convo1utions.
  • a cord twisted in the opposite direction tol Athe knitting (which will be hereinafter designated as a, cord with open convolutions)V that is to say, in the case of yarns of various colours, a cord with a lengthwise colour ⁇ disposition, it is required to twist the said cord in the contrary direction to its natural spiral turns produced by knitting, thus requiring the use of special 2 machines with a consequent increase in the cost of the finished product.
  • Our invention has for its object to provide a machine for the'direct obtainment of cords @with open convolutions
  • another object of the invention is to provide amachine which is adapted for the production of such cords '4 with open convolutions, but which may be readily converted into a machine for the manufactureof cords with closed convolutions
  • Fig. 1 is an elevational view, with parts broken away, of a constructional form of the machine which is arranged for the manufacture of cords with open convolutions, two
  • Fig. 2 is a partial vertical section of the cam cylinder.
  • Fig. 3 is an elevational view of a needle.
  • Fi 4 is an elevational view of a needle guidlng'tube. r
  • Fig. v5 is a like view of the needle bed.
  • Figs. 6 and 7 are dia animatie views showing two colour cords with closed convolutions. and with open convolutions, y re spectively. t
  • bracket 24 is a suitable bracket support-by means of the upright spacers .cylinder 36, secured to an outer ring 34.
  • the needle bed 25 (Fig. 5) having vertical needle grooves 251 adapted to receive the needleshanks 18 of the needles 21; said needles are guided in grooves of the head 28 of the needle guiding I tube 27 (Fig. 4).
  • Each needle shank 18 carries a roller 17 which protrudes between the raising and lowering cams 39-40 of the cam
  • a screw 6, which may enter a hole in the pulley 4, and a set screw 7 which is adapted to hold If the screw 6 is completely screwed in and 80 the screw 7 loosened, and if the driving belt 5 is passed around the pulley'23 (Fie. 1) the pulleys 4 and 4a-and hence the bo bin carrier 2 andthe cam cylinder 36-will be held stationary upon the bracket 24, whilst ⁇ the spindle 1p1, the needle bed 25 andthe needles will be rotated by the pulley 23.
  • the screw 6 is unscrewed and the screw 7 tightened against thes'haft 11, and the driving belt '5 passed around one of the pulleys 4 or 4, the spindle 11 and the needle bed 25 ⁇ will be held stationary, whilst the bobbin carrier 2 and the cam cylinder 36 are ro- .tated by the pulley 4 or 4,
  • the belt 5 isso disposed that the relative motion of the bobbins relativelv to the needle bed will be the same as in the preceding case.
  • the needles will rotate -with versa), and the rollers 17 thus move between 10 Cil the cams 39-40 and reciprocate the needles 18 in their grooves a.
  • the needles thus assume a vertical reciprocating motion, while rotating with reference to the bobbins, or inversely.
  • the thread which is delivered by the rings of the thread guides 9 is caught by the hooks of the needles which interlace the threads and ⁇ knit the tubular cord in the known manner; the cord is delivered froml the machine throu gh the tube 27 and the hollow spindle 11.
  • Fig. 6 shows such a cord, in the case of two-colour cord, similar to the cord of Fig. 6, obtained with the other arrangement of the machine.
  • the cord with open convolutions which is obtained in the arrangement of the machine shown in Fig. 1, will not remain in this form. When left to itself, it has a greater or less tendency to resume its natural shape, thus returning to the state of a cord with closed convolutions.
  • To maintain the cord in the open state it is necessary to provide a core the adhesion to the hollow cord'thereto it prevents the latter from untwisting and thus maintains it in the state of an open cord.
  • the ,use of a core is not limited to this case, and the cord with closed convolutions may also comprise such a core, if this appears necessary for the external aspect which is to be obtained.
  • the core is preferably impregnated with a preparation of such nature as to increase the adhesion of the core to the hollow cord and to maintain this adhesion in spite of any subsequent handling ⁇ or treatment of the cord such as dyeing, or hot water or steam treatment, and the like.
  • the core is sized by immersion in a bath of gelatin l which is softened by glycerin in order to maintain the desired flexibility of the cord, and is rendered insoluble by means of formol or the like.
  • the means for applying adhesive ⁇ to the core are not illustrated, since it does not form part of of the present invention and may be any conventionalmeans.
  • the core 13 thus prepared is fed at the top of the machine, passing for instance over the diagrammatically represented by aA pulley i 80 with counterweight 81, adapted to prevent the lower part of the cord from r0- tating about its axis and then upon a bar 82, the cord being nally wound upon the bobbin 83 which is rotatably secured to a pulley 84, movable on an axle 85, mounted on the bracket 86.
  • the bar 82 is given a vertical reciproeating motion to provide for the proper windin of the adjacent coils of cord upon the bo bin.
  • the cam cylinder 36 shown in Fig.v 2' comprises four high points and four low points, representing four separate cam portions corresponding to the four bobbinsl, so that the resulting cord may have four colours, if the said bobblns contain arn of four different colours.
  • the cord 1s of the closed type the four colours will be spirals of small pitch (Fig. 6).
  • the cord is of the open type, the colours will form strips along the length of the cord (lengthwise colour) or at least spirals of elongated pitch (Fig. 7).
  • the machine has a cam with four operative portions, as shown in Fig. 2, it is thus possible to produce cords having one, two, three or four different colours according to the number ofrdiferent threads, said colours being arranged as desired at the periphery.
  • a frame In a machine for lmitting tubular cord, a frame, a-spindle rotatably mounted in said frame, a needle bed secured to said spindle, a pulley keyed on said spindle, means for detachably securing said spindle to said frame, a b obbin carrier loose .on said spindle, a pulley secured to said bobbin carrier, a cam cylinder secured to said pulley, Vmeans for detachably securing said latter pulley to said frame, means for driving either of said pulleys, a core feeding device, and means for holding against-rotation the cord delivered by the machine.
