  • One of the objects of the improvements is to provide a method in which the back-rotation devices of modern rope-making machines and the advantages obtained thereby are retained and the above disadvantage avoided, so that the manufacture of ropes consisting entirely or partly of non-circular wires is made possible on such rope-making machines.
  • the non-circular wires which are to be made into rope are, before they are made into rope, i. e.

  • Fig. 10 is a detail sectional view showing a part 10 of a rope composed of wires which are circular in cross-section and wires which are irregular in cross-section,
  • Fig. 11 is a cross-section on an enlarged scale of the wire shown in Fig. 8, and
  • Fig. 12 is a detail sectional view similar to the one illustrated in Fig. 10 and showing a part of the rope made from wires of Z-shaped cross section.
  • my improved method 2 comprises the step of preparing the wires from which the rope is to be made, and the step of making the rope from such wires.
  • the lastnam'd step may be carried out in a manner known in the art'and on a rope-making ma- 25 chine comprising back rotation devices.
  • a rope-making ma- 25 chine comprising back rotation devices.
  • Suchv machines. are known in the art I deem it not necessary to describe-the same, and it is sufiicient only to describe; the step of the method and the machine for preliminarily twisting the wire.
  • the machine comprises a supply roller 2, a twisting device V, a draw-off wheel [2 mounted on uprights 25, and a winding-up drum or reel 13 mounted on uprights .il.
  • the supply reel 2, carrying non-circular wire I supplied by the wire factory is mounted in a yoke 3 which is rotatably mounted in uprights 4 and 5, and which is adapted. to be rotated through the intermediary of gear wheels l4 and 40 I5 from a main driving shaft IS, the said'shaft receiving power by means of a belt gearing comprising pulleys mounted on the shaft.
  • left hand trunnion H of the yoke 3 is formed with an axial bore, and through the said bore the wire I is passed to the twisting device V.
  • the said twisting device is mounted on uprights 42 and 43, and it comprises a frame com'- posed of end plates 54 connected with each other I by longitudinal bars 45, and blocks 28, 29 and 30 mounted thereon.
  • rollers or dies 9 I0 and l I are mounted, which dies or rollers are formed with grooves corresponding to the cross-sectional form of the wire to be treated.
  • the blocks ga, 29 and 3c 55 and the rollers carried thereby are adapted to be set different distances away from each other according to the twist to be imparted to the wire I.
  • the said blocks are connected with each other by a screw-threaded spindle 3
  • the angular relationship of the successive rollers or dies may be variable.
  • the rollers are mounted in disks 46 disposedin circular holes of the blocks, and adapted to be fixed in the desired positions by means of clamping screws 41 engaging in circumferential slots 48', of the flanges of the disks.
  • the displacement of the pairs of rollers 9, H), II with respect to one another is only stated as 180 by way of example. Any other angular relationship can, however, be employed for the generation of one and the same helical winding.
  • the regulation is then brought about by merely changing the distance of the pairs of rollers from one another, as this displacement, of course, always bears a certain relationship to the angular relationship of the pairs of rollers, if a helical twist of definite pitch is to be generated in the wire.
  • the frame 44 is adapted to be rotated from the shaft 3 through the intermediary of gear wheels [1, l8 and 19.
  • the whole twisting device V therefore, revolves together with the yoke 3 containing the non-circular wire to be twisted, and it will be understood that the gear wheels l1, l8, l9 and l4, I5, I may be exchanged for varying the rate of the rotary movement.
  • the drum I2 is likewise rotated from the shaft l6 through the intermediary of bevel gear wheels 50 and spur gears 24.
  • a motor 26 and gearing 2'! may be provided, which will be described hereafter with reference to Fig. 2.
  • the wire taken from the supply roller 2 is passed through the bore of the trunnion 4
  • a twist is imparted to the wire by the pairs of rollers, and the wire receives, on account of the passage through the rotating twisting device with the simultaneous rotation of the yoke 3 which is positively connected with this device, a twist of 360; the wire is, therefore, twistedinto the form of an exact helix.
  • the shaft I6 is driven through the intermediary of interchangeable transmission wheels 20, 2
  • the motor 26 is provided which rotates the drum through an intermediate gear 21.
  • the non-circular wire leaves the twisting device Vin the form of an exact helix of the desired pitch.
  • the wire so treated still possesses, however, a very high back-springing force, and therefore the tendency to spring back again into the original fiat form.
  • This back-springing force would, as above mentioned, be detrimental to the quality of the rope.
  • the back-springing force frequently amounts to 30 per cent of the rotation of the wire, 1. e. a non-circular wire twisted about its axis to 360 springs back again by about 120. The amount of this back-rotation depends naturally on the form and the rigidity of the material from which the non-circular wire is manufactured.
  • the length of the wire section drawn through the twisting device by the draw-off wheel IZ-in one rotation of the twisting device V (i. e., therefore the draw-off speed of the drawing-off wheel) is chosen greater than the length of twist generated on account of the positioning of the pairs of rollers 9 and II.
  • the difference between the drawing-off length and the length of twist which latter is necessarily fixed by the separation of the pairs of rollers 9 and II, is different according to the material of the wire and can be easily ascertained by experiment.
  • a further essential advantage of the method according to the invention is that non-circular I of course, be removed by a second passage through the above described twisting device, as with a suitable placing of the rollers or dies 9, In, H, the
  • number of revolutions of the yoke 3 is either a1 lowedto lag behind the number of revolutions of the twisting device V-by a corresponding amount, 1 or the drawing-d speed of the draw-ofi wheel I2 noticed that after this untwisting-the pitch of is increased.
  • the nearly stress-free wire,which is wound on the roping or supply drum l3 after passing through the twisting device is, in the making into rope by the use of the displaceable back-rotation device ofthe rope-making machine, so far untwisted in the direction opposed to its spiral line, as the rigidity of the material requires and appears desirable; in this connection, however, it is to be the spiral line of the twisted wire corresponds exactly to the length which is necessary for the intended length of twist of the finished rope.
  • the twisting device V supports a device which automatically marks every twist on thewire. This marking must, if the'wires to be made into the rope are uniformly rare-twisted, form, in the making of the-rope, each time annular markings round the circumference of the rope, whose mutual distance corresponds to the twist length of the rope. If, during the rope-making, the marking of one wire compared with the marking of the other wires leads or lags, it is thus immediately to be seen that the pitch of the spiral line generated in the twisting device of the appro-- priate wire is not correct. By forward or backrotation of the supply bobbin in the rope-making machine carrying the appropriate wire, the defeet can immediately be compensated for.
  • the marking arrangement consists of a colour container 32 which is fixed on a lever 34 rotatable round a pivot 33.
  • a control cam 35 rotating with the twisting device V and coacting with the lever 34 lifts and lets fall the colour vessel 32 at equal intervals which correspond each time to a twisting step of the wire I, so that the twisted wire receives its marking by the colour flowing out from the point of the colour container.
  • Fig. 8 I have shown a wire of segmental cross-section, which has been twisted into the desired form for making the rope therefrom.
  • the successive cross-sections imparted to the wire have been indicated in dotted lines, and for more conveniently following the change in the positions of the cross-sections, the marginal lines thereof have received the characters a, b, c, d.
  • Fig. 11 shows the cross-section of the wire illustrated in Fig. 8 on an enlarged scale.
  • Figs. 9 I have illustrated a wire' of substantially Z-shaped cross-section, and the successive cross-sections thereof, corresponding marginal lines having received the characters a and b.
  • Fig. 10 I have shown apart of a rope composedof wires which are circular in cross-section and wires l which are substantially trapezoidal in cross-section, the side faces of the said wires being curved to accommodate the wires of circular cross-section. For more clearly showing the said wires the wires of circular cross-section have been shown in broken lines.
  • Fig. 12 shows a part of a rope made from wires of the construction shown in Fig. 9.
  • pitch is used to indicate the lineal distance along or parallel to the axis between corresponding points upon the twist.
  • An apparatus for twisting wire comprising a die adapted'to grip the wire, means for supplying the wire to said die, wire through said die, means for rotating said drawing means and die relatively to each other, and means operative whenever said die and drawing means have been rotated relatively to each other through equal angles for producing a mark on said wire.
  • An apparatus for twisting wire comprising a die adapted to grip the wire, means for supplying the wire to said die, means for drawing the wire through said die, means, for rotating said drawing means and die relatively to each other, and a 'rockable marking device adapted to produce a mark on the wire and comprising a cam taking part in the relative rotary movement of said die and drawing means for throwing said r marking device into operation.
