Definitions

  • the present invention relates to guide flyers for yarn, rope or other filament-like material, to be employed in doubling frames, rope-making machines, stranding machines, or similar machines, in other words to those structures which are connected in the form of a link between the opposite ends of the rotating part of the said machines and which have the function of guiding the yearn longitudinally, preventing its deformation by centrifugal force.
  • Document US-A-3 793 819 discloses a guide flyer for yarn, strand or any other filament-like material, to be employed in doubling frames, rope-making machines, stranding machines or similar machines.
  • Said guide flyer comprises a body having a substantially flat cross section and having an aerodynamic profile, provided with a longitudinal median channel the bottom of which defines a first strip and which channel is closed by a second strip.
  • the flyer according to the invention should provide a simplified construction and a high degree of reliability in operation.
  • the flyer comprises a body 1 having a flat cross section and having a suitably aerodynamic profile, made, for example, from carbon fibre or from any other material, including composite material, suitable for the purpose.
  • the body 1 has a longitudinal channel 2, of rectangular section for example, in the median position on one face.
  • the bottom of the channel 2 is lined with a strip 3 made of steel or other suitable strong material having a low coefficient of friction and such that it does not damage the yarn to be guided.
  • the strip 3 may have a width greater than that of the channel 2, so that opposite portions 103 of the strip, which may be pierced or bent into the form of a fin if required, are embedded in the body 1 to provide it with greater strength.
  • This variant may enable the body 1 to be made from less expensive and less strong materials than the carbon fibre mentioned previously.
  • the strip 3 is provided with holes 4 and 104 located at short distances from the longitudinal edges of the strip and distributed over the whole length of the flyer with a constant and suitable spacing.
  • the body 1 is provided with holes 5-105 aligned with the holes 4-104.
  • the channel 2 is closed by a strip 6 of the same material as the strip 3, also provided with holes 7-107 at short distances from its longitudinal edges and aligned with the aforesaid holes 4-104 and 5-105.
  • the strip 6 is kept parallel to the strip 3 and in the correct position to close the channel 2 by the interposition between the strips of identical bushes 8-108, made of ceramic or other suitable material, which are aligned axially with the holes 4-5-7 and 104-105-107 and through which pass bolts or screws 9-109 or other suitable means such as rivets or other devices by means of which the parts 6-8-108-3 are fixed to the body 1 of the flyer.
  • an ideal continuous tubular guide 10 is formed in the channel 2 which is covered and closed, and that the yarn or strand F runs in this guide and is sheltered from the dynamic wind, being supported on the strip 3 or 6 which is towards the outside, and supported on the row of bushes 8 or 108 which is opposite the leading edge of rotation of the flyer.
  • the strip 6 is towards the outside and that the direction of rotation of the flyer is as indicated by the arrow Z.
  • the dimensions of the guide 10 are suitably greater than the maximum diameter of the yarn or strand which is running in the flyer.
