Definitions

  • the invention concerns a metal spool for winding yarns, particularly thin or extra thin yarns, with a count of about 20-30 denier, of the type able to be used, for example, to make women's stockings.
  • the spool allows to make very consistent bobbins, weighing about 3.5-4 Kg or more, and to work at very high winding speeds, in the region of about 2,000 metres per minute.
  • the spools To prevent the central core from being deformed due to this pressure, it is therefore necessary for the spools to be very strong and resistant. At the same time, however, the spools have to be quite light, so that they can be easily handled by the workers who have to move the full spools, usually manually, for example from a winding machine of the bobbins to another machine for weaving or making up.
  • the state of the art includes a metal spool consisting of a central cylindrical core, hollow inside, and a single flange welded to one end of the central core.
  • This conventional spool weighs about 700 g, has a standardized length of 280 mm and a size such as to allow to form spools of yarn with a weight of about 600-700 g, so that the ratio between the weight of the wound yarn and the weight of the empty spool is about 1:1.
  • the spool for winding yarns according to the invention is set forth and characterized in the main claim, while the dependent claims describe other innovative characteristics of the invention.
  • One purpose of the invention is to achieve a spool which, also with a standardized length, a limited weight and easy to handle, allows to wind a large quantity of yarn, in the region of about 3,500-4,000 g, particularly of fine or super-fine yarn, that is to say, with a count of about 20-30 denier.
  • the weight of the spool is contained to a value scarcely above the weight of conventional spools, the ratio between the weight of the yarn wound onto the bobbins and the weight of the empty spool increases by about three times compared with the state of the art.
  • the spool according to the invention comprises a substantially cylindrical central core, hollow inside, and a flange at one end thereof, both made of aluminium alloy and zinc or similar alloys with very high resistance.
  • the aluminium alloy is the one known internationally under the registration number 7075 or similar.
  • the central core has an outer diameter of between about 49 and 53 mm and an inner diameter of between about 41 and 45 mm, while the flange has a thickness of between about 11 and 13 mm and an outer diameter of between about 166 and 170 mm.
  • the overall weight of the spool is between about 1,200 and 1,300 g.
  • Another purpose of the invention is to achieve a spool which allows to detect, easily and automatically, when the yarn has finished unwinding around its central core, using photo detector systems of a conventional type.
  • the central core of the spool is light absorbent.
  • the central core comprises a dark surface, made for example by anodizing the aluminium alloy of which the central core is made, which otherwise would reflect the light.
  • a spool 10 according to the invention comprises a central core 11, substantially cylindrical in shape, to the first end 12 of which a flange 13 is friction welded, arranged substantially orthogonal to the longitudinal axis 15 of the central core 11.
  • the central core 11 is provided inside with a cylindrical cavity 16, coaxial with the longitudinal axis 15 and through, and is shaped in such a manner as to have, at a second end 17 thereof, an annular ribbing 18 and an annular seating 19 to house a conventional count marker, not shown in the drawing, for example of the type described in the Italian patent n°. 1.299.748 granted to this Applicant on 4 April 2000.
  • Both the central core 11 and the flange 13 are advantageously made of aluminium alloy 7075 or similar.
  • the central core 11 has a length L of about 268 mm, an outer diameter D 1 of about 51 mm and an inner diameter D 2 of about 43 mm, while the flange 13 has a thickness S of about 12 mm and an outer diameter D 3 of about 168 mm.
  • the overall weight of the spool 10 is about 1,250 g.
  • the time needed to completely wind the yarn, at a winding speed of about 2,000 metres per minute, is about 60-65 mins.
  • the outer surface 20 of the central core 11 is anodized and black, or in any case a very dark color, so that it is light absorbent, unlike the yarn wound onto the spool 10 which is usually light in color and hence reflects the light.
  • any conventional photocell not shown in the drawing, is able to recognize when the yarn has finished unwinding from the spool 10, and send a corresponding electric signal able to stop the machine on which the spool 10 is mounted.
