Definitions

  • the centers are almost always shaped differently at their two ends, for a variety of reasons; the packages must be formed on correctly oriented centers, and the formed packages must be placed - for later handling - in a specific orientation, which it is not easy to judge from the ends of the support which barely project from the mass of yarn forming the package.
  • the invention relates to a center made to facilitate the perception of the orientation of the center, by the ends barely projecting from the center, which operation may be carried out either by eye or by an automated system.
  • Document US-A-4 656 278 discloses a colour identification of the ends of a center, to facilitate and to check the orientation of the center.
  • Documents US-A-2 961 715 and US-A-2 944 757 provide centers in plastic materials, which are made with a first molded piece in a first mold with a first operation of injection of plastic material, and with a second molded piece with a second injection operation against the first piece and to adhere thereon, utilizing a second mold.
  • the yarn package center - for handling purposes in spinning, package winding, twisting, dyeing, weaving and the like - is made of injection-molded synthetic resin and has one end of a different color from the opposite end, for the purpose of facilitating and of checking the orientation of the center and hence of the yarn package from which its two ends slightly project.
  • the center may be checked easily by eye or by a chromatic sensor, owing to the color difference which is produced in the center.
  • the center is molded in a sole piece with plastic material of two colors.
  • the center is of disposable type or is designed for once-only use with the material being reused after being ground down, and is made mostly of a dark material, in particular black, and of a material of contrasting color limited to a terminal portion and to the associated end.
  • the drawing shows a possible embodiment of the invention, and shows in particular a center of a conventional type in an external, partially sectioned view.
  • the accompanying drawing shows the center, which is indicated as a whole by 1, with a top end 1A and a bottom end 1B which differ slightly in shape and project slightly from the mass M of the yarn package which is cross wound onto said center.
  • the two ends 1A and 1B project very slightly from said mass and therefore are already necessarily almost out of sight, and their shapes and sizes are quite difficult to tell apart, especially by eye.
  • the center 1 is to be made from two different colors of synthetic resin, which are indicated by 1X and 1Y. These colors are injected by methods which may be readily envisioned to obtain the support as a single piece formed from said two materials, which are more or less evenly separated along a line of separation indicated in the drawing by 1Z.
  • the preponderant material as regards quantity, which is shown in the drawing by 1X, advantageously is very dark or even black while the material present in lesser quantity, shown in the drawing by 1Y, is of a more or less vivid color that is distinctly lighter than the color 1X, to provide very clear chromatic discrimination between the two ends 1A and 1B.
  • Very dark synthetic resin is used for the major amount rather than the light-colored resin because it is advantageous to be able to use the material recovered by grinding down centers that have already served as single-use centers in order to form the starting material for the molding of new, similar centers.
  • the low presence of light-colored material, as at 1Y, as opposed to the preponderant presence of very dark material, as at 1X, in the ground material allows the recovered material to be used as the material for the formation of the preponderant dark-cored part, with the addition, if necessary, of colorants and/or new and very dark resin.
