Definitions

  • the filaments are individually guided from the storage spools, with a change of direction to the direction opposite to that in which they are drawn off, to a stranding head, in which they are stranded.
  • the separate guiding of the filaments from the storage spools to the stranding head provides the advantage that during their travel from the spools to the stranding head the filaments are subjected only to the deformations resulting from changes of direction and the stresses resulting therefrom.
  • the method according to the invention comprises the steps of feeding the filaments from the storage spools towards a uniting point, and continuously stranding the filaments into a stranded material, and deflecting the stranded material in a direction opposite to the feeding direction.
  • This method is intended to further reduce the deformations and forces acting on the filaments on their path to the stranding point, in order to obtain double lay stranding of a high quality.
  • This method may be applied not only to the stranding of materials having relatively low strength and elasticity'values, but also to materials having relatively high values of this type.
  • the high speed stranding machine comprises a substantially stationary spool carrier disposed between two guide carriers, first drive means to rotate the guide carriers synchronously about a common machine axis, a pair of deflector devices being associated with each of the guide carriers, the deflector devices being disposed in a com-.
  • the stranding head preferably comprises a stranding nipple forming the stranding point and a roller system for guiding the stranded product in its path on leaving the nipple.
  • a guide roller is associated with some of the storage spools and is so disposed in relation to the guide means that, when the machine is operative, each filament running ofi from the spools runs into the guide member at an acute angle to the common axis.
  • the guide member may comprise a perforated and axially displaceable disc, which is axially displaceable for the purpose of adjusting the stranding angle.
  • each of the deflector devices comprise a deflector segment having a guide groove.
  • the second drive means may comprise an infinitely variable transmission.
  • the high speed stranding machine according to the invention has an extremely short construction and in consequence of the small rotating masses is suitable for achieving high stranding outputs at high speeds of rotation.
  • the high speed stranding machine shown comprises a spool carrier la, which is inertially mounted between guide carriers 2a and 2b, constructed as spool carrier bearings, so as to be substantially stationary in relation to said guide carriers.
  • the guide carriers 2a, 2b are mounted in bearing supports 3 and are provided with deflector segments 120.
  • the deflector segments I20 are disposed in pairs following one another and which are secured to the guide carriers to rotate concentrically with the latter about the machine axis 5.
  • Each of the deflector segments, which are aligned in a common plane through the machine axis, are provided with a groove or channel for guiding the stranded material along a path thereformed;
  • the spool carrier 1a there are accommodated storage spools 6 which may selectively, be disposed one behind the other, side by side, and/or one above the other.
  • the filaments 19, which are drawn off from the storage spools during the operation of the high speed stranding machine are in each case guided over a deflector roller 4, associated in each case with a storage spool 6.
  • the filaments 19 are fed on to a perforated plate 121 which serves as a cable guide member and which is disposed within the spool carrier la so as to be stationary and axially displaceable along the main machine axis 5.
  • the filaments 19 run into the perforated-disc at an acute angle to the axis of the latter, whereby a tensional reaction oppositely to the drawoff direction is limited.
  • An exception hereto is a heart wire, which is preferably introduced centrally into the perforated disc 121 from a heart wire spool 18.
  • the perforated disc 121 is followedby a stranding head 7 comprising a bearing sleeve which is fastened on the spool carrier 1a and in which a stranding nipple 122 is mounted to be rotatable about the main machine axis 5.
  • the filaments 19 run into the stranding nipple 122 which does not apply any pressing action to the material being stranded or to the stranded product being formed.
  • Stranding in the stranding nipple 122 is accomplished since on leaving the stranding nipple I22 the product passes through a roller system 123 comprising at least three rollers, which effect a temporary deflection of the product out of the main machine axis 5.
  • rollers which are mounted for free rotation, rotate concentrically about the main machine axis 5 and ensure that the stranded product receives a rotational speed synchronous to the stranding head 7.
  • the stranded material which is completely and accurately stranded, is subsequently deflected by means of the deflector segments back past the guide carriers 2a, 2b into a direction opposite to the direction in which the material is drawn off from the storage spools and on leaving the stranding machine. It is then fed to a detwisting device (not shown) when the material to be stranded is one of relatively great strength and elasticity. After leaving the detwisting device the stranded material passes to a receiving reel (likewise not shown).
  • the stranding head 7 is rotated in the same direction as the guide carriers 2a, 2b, its rotational speed being approximately twice as great as that of the guide carriers 2a, 2b.
  • the guide carriers 2a, 2b are driven through a cogged belt 111 coupled to the main machine shaft (not further shown)
  • the stranding head 7 is driven by the guide carriers 20, 2b through gearing 124, 125, which hasa transmission ratio such that the stranding head 7 rotates in the same direction as that of the guide carriers 2a, 2b, but at twice the speed.
  • infinitely variable transmission means may replace the gearing in the drive to the stranding head 7 for regulating the speed of the stranding head 7 relative to the guide carriers 2a, 2b. Regulation of the relative speed ratio through an infinitely variable transmission affords control of the tension within the finished stranded product.
  • the travelling direction of the stranded product is reversed by means of the deflector segments 120, the finished stranded material is not rotated.
  • the stranding material rotates at the same speed as the stranding head 7. However, when after leaving the latter, it travels to the bearing 3, (on the left in the drawing) where it leaves the machine without any rotary movement about its own longitudinal axis.
  • the stranded material which on leaving the machine runs into a detwisting device and is then fed to a receiving reel, has a particularly high quality of stranding, while the filaments in the strand have a ready tendency to close up.
  • a method of stranding filaments to form ropes, cores of cables or the like which comprises the steps of a. feeding the filaments from storage spools towards ajunction,
  • a spool carrier inertially supported by said pair of guide carriers and adapted to carry a plurality of spools of filaments
  • a stranding device rotatably coaxially mounted in said spool carrier, e. a guide member inertially mounted in said spool carrier for feeding the filaments to the stranding device, and,
  • driving means operatively connected to said pair of guide carriers and said stranding device and adapted to rotate the latter at about twice the speed of the former.
  • a high speed stranding machine as defined in claim 2 comprising a stranding nipple forming the stranding point of the stranding device, and further comprising a roller system for guiding the stranded product in a predetermined path on leaving the nipple.
  • each of the deflector devices is a deflector segment having a guide groove.
