Definitions

  • the primary object of the invention is the provision of a rope-making machine with which the production of perfect winding layers is made possible in a simple manner.
  • This may be achieved through an arrangement such that strand carriers delivering in each case one strand are arranged at the circumference of a circular rope-whipping plate provided with a hollow shaft, which plate rotates at a constant, though adjustable turning relative to the lineal travel of the rope core as it is drawn through the machine by a draw-off device.
  • the core is supplied through the hollow shaft of the plate from the side opposite the material carriers.
  • Above the whipping plate the strands supplied from the individual strand carriers are wound spirally about the core.
  • the machine has a winding device for winding the spirally wound rope under constant rope tension.
  • the individual strand carriers are equipped with allocated thread or strand brakes of known type, with the aid of which the tension of the strands running to the winding point can be adjusted according to the requirements.
  • the strand carriers are arranged to slide in a concentric groove near the plate or disk edge in such a way that at any time an arbitrarily large number of carriers can be accommodated, the limit being the maximum resulting from the diameter of the groove circle and the diameters of the individual spools.
  • the coupling between plate drive and draw-off device is, according to the invention, such that rate of draw-off of the rope core through the machine can be adjusted, for example, by means of an infinitely variable gear of known design in the range corresponding to the practical requirements, relative to the rate of rotation of the plate, or vice versa.
  • rate of draw-off of the rope core through the machine can be adjusted, for example, by means of an infinitely variable gear of known design in the range corresponding to the practical requirements, relative to the rate of rotation of the plate, or vice versa.
  • the relative rates of lineal take-up of the rope core by the take-off device and the rate of rotation of the plate(s) should remain constant, e.g., by driving both from the same drive source, to provide a constant, predetermined rate of rotation of the plate per lineal unit of travel of the core.
  • the device is adapted for whipping two winding layers at the same time by an arrangement such that two plates of different diameters, rotated about a common axis, but independently of one another and at different speeds, if desired, rotate in the particular direction desired.
  • the number of concentrically turning rope-Whipping plates driven independently of one another in speed and direction and carrying the strand carriers may even exceed two, so that thereby, possibly, the application of all the core wound layers upon one machine passage becomes possible.
  • FIG. 1 is a side elevation, partly in section, of an embodiment of the invention
  • FIG. 2 is a side elevation, partly in section, of another embodiment of the invention.
  • FIG. 3 is a top plan View to show the detail of a typical strand brake mechanism which may be used in conjunction with the strand carriers of FIGS. 1 and 2.
  • the rope core 1 may be a single strand, a group of parallel, untwisted strands, a group of slightly intertwisted strands, or a group of spirally wound strands. It may also be a core of the aforementioned type having one or more spirally wound layers wound thereabout in the event the ultimate rope is made by successive passages through the machine to apply the spirally wound layers thereon.
  • the rope core comes from the supply drum 2 and runs over the deflection roller 3 through the bore 10 in the axis of the rope whipping plate 9 to the rotating strand collector 5.
  • the strands 15, being supplied from the individual strand carriers 12 meet and are spirally wound in a layer about the core.
  • the rope, supplied with a new wound layer passes over the deflection roller 4 between the draw-off rollers 6, 7 to the winding drum 8.
  • the rope-whipping plate 9 has on its surface, near the circumference, a concentric groove 11 with dovetail cross section, in which the correspondingly shaped legs 14 of the strand carriers 12 are inserted with the aid of slots of known type.
  • Each of the strand carriers 12 has a device 13 which maintains constant the strand tension of the strands 15 drawn off the spools.
  • the rope-whipping plate by way of a suitable drive connection, is also connected with the draw-off rollers 6, 7.
  • the drive of the rope-whipping plate and its coupling with the draw-off device may also be accomplished in any other manner than that represented.
  • the illustrated draw-off device is a lower driven roller 7 and an upper idler roller 6.
  • the rope is drawn between these rollers without slippage.
  • the roller 7 has a pulley 35 driven by belt 36.
  • the belt 36 is mounted on pulley 37 which is mounted on the shaft of friction disc 38.
  • the disc 38 is rotatably driven by the wheel 39, the circumferential edge of which frictionally engages the face of disc 38.
  • the wheel 39 is movable toward and away from the radial center of disc 38 by virtue of support of its shaft 40 by the yoke arm 41.
  • the arm 41 is supported on a reciprocable support (not shown) by which the position of wheel 39 can be set in any position relative to the radial center of disc 38 to give the infinitely variable drive connection between the take-off device 6, 7 and the rotating plate 9.
  • the shaft 40 is connected telescopically to the shaft 42 by a conventional spline connection or other similar type connection and is rotatably driven by the shaft 42. This combination provides a stageless adjustable drive for making fine adjustments in the relative velocities at which the plate and means for drawing the rope core are driven by the driven means.
  • the winding drum 8 is driven in such a way that during the entire winding process the rope tension in the part '20 of the rope to be wound remains constant.
  • This may be achieved with any known means, as for example, independently of the remainining drive of the machine, with a Ferraris motor or slip motor of other construction which is capable of delivering a constant torque, or else by one of the known electric, hydraulic or mechanical slip couplings with constant output torque, in which arrangement then the drive may be coupled in common with the rest of the device.
  • the drive of drum 8 is not represented in detail in the drawing.
  • FIGURE 2 shows a rope machine according to the invention with two strand-whipping plates 21 and 22.
  • the rope core 1 runs over the deflection roller 3 upward through the axis of the strand-whipping plates and in so doing passes through the two strand collectors 25 and 26, whereupon it runs onward over the upper deflection roller 4 to the draw-elf device and thereupon to the winding drum in similar fashion to the embodiment of FIGURE 1.
  • Both strand-whipping plates each have only one circular, dovetail groove 23 and 24 near the outer circumference, in which there are inserted the strand spool carriers 12 with their legs 14.
  • the rope core 1 runs upward through the axial bore 27 of the upper plate 21, while the rope-whipping plate 22 has a hub in which is rotatably journalled the hub of the ropewhipping plate 21. Both hubs have on their lower end a spur gear 29 and 30, through which they are driven by a gear arrangement and are simultaneously coupled with the draw-01f device in the manner of the embodiment of FIG. 1.
  • the strands 31 and 32 coming from the strand spool carriers 12 run to the strand collectors 25 and 26, where they are spirally wound about the rope core 1.
  • the lower strand collector 25 is connected by suitable means, for example, with the aid of a strap, with the rope-whipping plate 21, to keep the two strand collectors spaced apart.
  • the drive of the rope-whipping plates 9 or 21 and 22 may be accomplished in any usual manner, so long as it allows no slip between those elements of the drive which influence the relative turning rates of the strand-whipping plates on the one hand and of the draw-off device on the other hand. With such a slip it would not be possible to maintain the particular whipping lengths constant.
  • the drive of the strand-whipping plates 21 and 22 is designed in such a way that the rotation rate and direction of rotation of each plate can be set independently of the other, at will, before setting the apparatus in operation.
  • the rope-whipping plate 9 in FIGURE 1 may be adapted to any desired whipping length and direction. Thereby it becomes possible, with the aid of the apparatus described, to achieve any desired wound layer formation.
  • the rope core 1 should have as constant as possible a rope tension between the deflection rollers 3 and 4, in order to prevent a deformation of the rope core. In the embodiment this is provided by a weight 18 hanging on a brake rope 19, a usual form for providing tension in the rope core drawn from the supply spool 2.
  • the strand collectors 5, 25 and 26 each is simply a fixed ring through the center opening of which passes the rope core.
  • the strands being wound on the core slide across the lower edge of the center opening and are wound on the core in spiral, side-by-side relationship at the site of the strand collector.
  • the device 13 for maintaining constant strand tension may be any one of many types of devices known in the art for this purpose.
  • FIG. 3 one of such devices, which consists of a rod 43 having mounted thereon a fixed disc 44 and a slidable disc 45.
  • the disc 45 is pressed toward the disc 44 by a coil spring 46.
  • the coil spring is mounted about the rod 43 between the plate 45 and a nut 47 threaded on the threaded end of rod 43.
  • the strand 15 passes between the plates 44, 45.
  • the pressure of the plates against the strands provides a braking action on the strands.
  • the pressure exerted is adjusted by changing the pressure of spring 46 on plate 45 upon rotating nut 47.
  • the ropes produced by the machine of the invention are characterized by a core of the'aforesaid character having at least one and usually two or more layers of spiral strands.
  • the strands in each layer are laid side-by side, and in the respective layers of multi-layered ropes, the strands may be wound in the same or opposite direction.
  • the number of strands used to form each layer may be adjusted to correspond with the desired number of turns per unit length, diameter of the strands, and/or diameter of the respective spiral-wound layer to provide layers in which the individual strands are applied in close, side-by-side relationship.
  • the rope such as a mountaineering rope made of strands of synthetic filaments
  • the rope is finished by providing about the spiral-wound core a mantle, which is usually a cross-braided mantle.
  • the mantle is applied over the core on another well known machine which does not constitute a part of this invention.
  • the mountaineering ropes are best produced with about 60% of the total mass of the rope strands in the core and spirally wound layers about the core and 40% of the total mass in the strands of the mantle. Ropes of this character have wound layers which do not twist upon loading of the rope.
