Definitions

  • the invention relates to a machine for manufacturing a cable with means for guiding a plurality of wires towards each other, means for providing an S and/or 2" lay in the wires so guided and means for holding together the wires that have been laid and for traversing the cable thus obtained.
  • Machines for manufacturing cables or strands having parallel running wires enclosed in a sheath are also well known.
  • guide nipples are generally used for guiding the wires towards each other. Such guide nipples are necessary particularly when the wires are laid according to a three-dimensional serpentine pattern, Le, a combination of S" or Z lay. I-Iigh frictional forces occur in such nipples.
  • the primary object of the present invention is to provide means for holding together the wires that have been laid in a manner wherein the above-noted frictional forces are avoided and wherein torsional stresses are controlled in a more favorable way.
  • this object is achieved by providing means for holding together the wires which have been laid, said means taking the form of an endless strap clamping the cable over a portion thereof and running helically around same.
  • the strap encloses the wires at their meeting point and keeps them together for a time sufficient for arranging the helical binding wire or binding strip, the latter being supplied between the windings of the clamping strap. Therefore, the binding wire or binding strip is supplied at the position where the clamping takes place, the most favorable position.
  • the strap performs a circular movement.
  • the guide rollers of the clamping strap are preferably located on an element placed in coaxial relationship with the cable, said element being rotatable around said cable and, if desired, driven by external means.
  • the rotatable element which carries the guide rollers hereafter termed the spinner, makes it possible to perform a winding movement of the clamping strap around the moving cable so that said strap fulfills only the clamping function; no longitudinal forces being developed relative to the cable and, consequently, only slight frictional forces occur between the clamping strap and the cable.
  • the rate of circulation of the spinner is adapted to the velocity of movement of the cable; and thusly the ratio between velocity of movement of the cable and the rate of circulation of the spinner determines the pitch of the clamping strap on the cable. In this way, a means is provided which fully replaces the cable nipple and does so in a manner substantially free from frictional forces.
  • Another advantage inherent in the device of the present invention resides in the fact that with cables comprising wires running according to a three-dimensional serpentine pattern, the binding wire, necessary for holding the wires together, may be located at the most favorable position.
  • the clamping strap it is possible to independently drive at least one of the guide rollers of the clamping strap. It is then possible to create a torsional force in the cable independent of that force resulting from the rotation of the spinner. In this way, it is possible to create an added torsional force in the cable which either adds to or subtracts from other torsional forces present therein.
  • the drive of the guide roller may take the form of an element rotatably mounted on the spinner. In this way, the drive is realized in an uncomplex manner.
  • the machine of the present invention be provided with numerous driving mechanisms. More particularly, there are provided a driving motor for the spinner, a drive mechanism for the clamping strap, a drive mechanism for controlling the movement of the cable, and a drive mechanism for the wire guiding wobble disc, said disc being rotatable in alternate directions.
  • a planetary or similarly functioning drive mechanism such as a differential gear may be provided, one branch being connected to a motor which may also drive the cable conveyor, the second branch being connected to a motor which may rotate the spinner, and the third branch being coupled to the driving means for the clamping strap.
  • Variable transmissions are preferably arranged between the motors and the planetary driving mechanism. Stepless transmissions are preferred since they make it possible to set the number of revolutions of two branches of a planetary transmission as desired, thus influencing the number of revolutions of the third branch in such a way that the desired speed of the clamping strap can be adapted to the speed of the spinner and the rate of displacement of the cable.
  • the machine of the present invention is provided with couplings for disengaging certain parts of the driving mechanism.
  • the spinner may be independently driven by the motor of the cable conveyor. This is desired where it is necessary that the clamping strap make a winding and an unwinding movement, almost frictionlessly, around the cable, thus replacing the function of the previously used nipple.
  • the machine is preferably manufactured in such a way that when a wobble disc is used, the driving mechanism of same can be easily engaged and disengaged. It is then possible to have the torsional operation of the clamping strap and the wobble disc occur independently.
  • FIG. I is a perspective view of the clamping strap portion of a cable winding machine constructed in accordance with the present invention.
  • FIG. 2 is a diagrammatic view of a cable winding illustrating numerous operational modes.
  • FIG. I shows a wobble disc I which can be rotated in alternate directions by driving means (not shown), said disc being provided with a number of openings (not shown) for guiding wires 2 around a core 3 according to a three-dimensional serpentine pattern, i.e., according to a combined S"Z" lay.
  • the core is supplied through the center of the wobble disc 2 and is moved with a speed corresponding to that of the cable 4, the cable being traversed by endless belts carried by members 5 and 6.
  • a disc 7 Concentric with the wobble disc 1 is a disc 7, said disc 7 being capable of rotation in the direction of arrow 8.
  • the disc 7 carries rods 9, l0 and 10 which carry, respectively, guide rollers ll, 12 and 13.
  • a device 14 for providing the cable with a helical running binding strap 15 is also carried by rod 9.
  • a relatively wide strip 16 runs around the rollers ll, 12, and 13; the strip being indicated on the cable at 17.
  • the strip 16 helically wraps the cable only in a localized area and grips the wires 2 running toward each other. Consequently, the correct shape of lay is readily secured and the binding strap is positioned at the time when and in the area where the wires 2 are pressed together.
  • the result of the spinner rotation is that the rear region 16a of the strip 16 winds on the cable while the front region 16b unwinds.
  • the clamping strap is wound and unwound substantially free from frictional forces.
  • a variation of these factors namely, the velocity of movement of the cable and the angular velocity of the spinner, makes it possible to create certain torsional stresses in the cable, to prevent same or to create a stabilization ett'ect.
  • this torsional adjustment may be realized by driving one or more of the guide rollers associated with the clamping strap.
  • Such a provision of drive means makes it possible to use as a variable the velocity of movement of the clamping strap in addition to the abovenoted variables formed by the rate of displacement of the cable and the angular velocity of the spinner.
  • the velocity of movement of the clamping strap may thus perform a positive or a negative twisting operation on the cable.
  • the wobble disc 1 comprising the guide eyes for the wires 2 and the core 3.
  • the spinner 7 with rods 9 and 10 appended thereto and the guide rollers ll, 12 and 13 for the clamping strap 16.
  • the rods 9 and 10 are elongated so that they extend past both guide rollers 12 and i3, a ring being rotatably mounted on these elongations.
  • Ring 20 may be driven via a belt 21 or the like and is coupled to a second ring 22.
  • a driving strap 24 runs over the ring 22 and then continues, via comer conveyors 23 on the spinner, over wheels 25 which are coupled to the guide rollers 12 and 13 of the strip 16. In this manner, a drive of the clamping strap 16 is achieved.
  • FIG. 2 also shows a main motor 26 which drives the belt conveyors 5 and 6 via the belt transmission 27.
  • Motor 26 may also provide the drive for the wobble disc 1 via a belt transmission 28, a worm and worm gear transmission 29 which converts a rotary movement into a reciprocating movement of an arm 30 and, consequently, of the rod 31 and the rack 32, the rack being connected to the wobble disc 1 by driving gear parts 33, 34 and the coupling 35.
  • the wobble disc can be stopped and rotated continuously in alternate directions.
  • a separate spinner motor 40 is provided for driving the spinner.
  • the main motor 26 is also coupled to a sun wheel 42 of a planetary transmission 43 via a stepless variable transmission 41.
  • the spinner motor 40 is connected to the outer set of teeth 45 of the planetary transmission 43. in this manner, satellites 46 may operate on the drive of the clamping strap 20 including wheels 25 via the belt transmission 47 and the coupling 48.
  • the most normal driving condition is that in which the main motor 26 drives the belt conveyors 5 and 6 and, consequently, controls the motion of the cable 4, motor 26 also driving the spinner 7 so that the clamping strap 16 performs its normal function.
  • the wobble disc functions normally and the couplings 35 and 37 are, therefore, engaged while the coupling 48 is disengaged.
  • a machine for manufacturing an elongated multistrand cable of the type comprising means for guiding a plurality of wires toward each other, means for temporarily positioning said plurality of wires in cable form and means for permanentiy securing said plurality of wires, the plurality of wires and said securing means forming the multistrand cable, and cable conveyor means to move the formed cable
  • the means for temporarily positioning the plurality of wires comprises an endless clamping strap helically traversing the cable for only a portion of its elongated dimension, a plurality of guide rollers spatially positioned around said cable, said clamping strap passing about and being guided by said plurality of guide rollers, a mounting element rotatably positioned in a coaxial relationship with said cable and having said guide rollers mounted thereon, a three-branch driving mechanism, a first drive means forming the first branch and driving said cable conveyor, a second drive means driving said rotatable mounting element and its mociated guide rollers and forming the second branch, and a third
