Abstract
Description
- 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.
- According to the present invention, there is provided a guide flyer of the type above disclosed comprising the features of the characterizing portion of claim 1.
- The characteristics of the flyer in question, and the advantages deriving therefrom, will be clearly understood from the following description which refers to the figures of the attached sheet of drawings, in which:
- Figure 1 is a plan portion view of the lyer;
- Figure 2 shows a transverse section through the flyer along the line II-II in Figure 1; and
- Figure 3 shows further details of the flyer in a section along the line III-III in Figure 2.
- It may be seen from the figures that 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 astrip 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. As shown by the broken lines in Figure 2, thestrip 3 may have a width greater than that of thechannel 2, so thatopposite 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 withholes 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 astrip 6 of the same material as thestrip 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. Thestrip 6 is kept parallel to thestrip 3 and in the correct position to close thechannel 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. - From Figure 2 it may be seen that an ideal continuous
tubular guide 10 is formed in thechannel 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 thestrip bushes 8 or 108 which is opposite the leading edge of rotation of the flyer. In the figures, for example, it is assumed that thestrip 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.

- A guide flyer according to claim 1, characterized by the fact that the said first strip (3) is secured to the body of the flyer by means of portions (103) which extend beyond the sides of the longitudinal channel (2) and which are embedded in the said body (1), while the second strip (6) is secured to the body (1) of the flyer by fastening means such as bolts, screw, rivets or other suitable means (9-109) which pass through the said bushes (8-108).
- A guide flyer according to any one of the preceding claims, characterised by the fact that the the said bushes (8-108) are arranged at the sides of the longitudinal channel (2) at suitable intervals of length, so as to suitably support the running yarn or rope (F) during operation of the guide flyer.
