Definitions

  • the object of the present invention is a reel for yarns, and particularly for sewing threads, which comprises a structure particularly suited to retain the free end of the thread in a firm and reliable manner.
  • Reels provided with means for retaining the thread end are known, for example, from the Italian Utility Model No. 156.815 of 3.3.1972, and from the European Patent application No. 85106273.7 of 22.5.1985, both in the name of the same Applicant.
  • These retention means comprise - in association to at least one of the ends of the cylindrical body forming the reel - a widened base and an annular collar, shortly spaced one from the other, between these two elements there being formed a groove, having a wedge-shaped cross section, suited to retain an end of the thread.
  • said groove between the base and the collar comprises opposed radial ribs, apt to improve even further the thread retention effect.
  • the object of the present invention is therefore to realize a reel for yarns, apt to solve this problem and to thus provide for a perfect retention of the thread end, both during use of the reel and, above all, during packaging thereof with automatic machines.
  • a reel for yarns particularly sewing threads, of the type comprising a cylindrical body, onto which the thread is wound and, at least at one end thereof, a widened base and a flange collar close to said base, between the base and the collar there being formed a groove for housing and retaining the thread end, characterized in that said widened base comprises an inner rim surrounding the cylindrical body at a short distance, in that at least one breakable staple is provided between said inner rim of the base and said cylindrical body, forming an element of connection between the base and the cylindrical body, and in that, onto the surface of said body there is formed, between said base and said collar, an annular rib with toothed profile, the outer radius of which is wider than that of said inner rim.
  • the reel according to the in­vention is formed of a main cylindrical body 1, onto which is wound the thread. At least at one of its ends the body 1 comprises a widened base 2 and a flange collar 3. The thread is wound onto the body 1 for a thickness corresponding to the radial dimension of the collar 3 and of the base 2, as indicated by the dashed and dotted line F in figure 2.
  • the base 2 has a central hole delimited by an inner rim 2a, which surrounds the body 1 at a short distance. Between the body 1 and the rim 2a there are provided radial tip-shaped staples 4 - shown more clearly in figure 3 - which form an element connecting the base 2 with the body 1.
  • the staples 4 have a small cross section, so as to be easily breakable.
  • annular rib 5 with a saw-toothed profile, the outer radius of which is wider than the radius of the inner rim 2a.
  • the saw-toothed profile faces with its beveled surface the rim 2a of the base 2.
  • the reel according to the invention is used in the following manner: once the thread has been wound - during production, for example on automatic winding machines - the free terminal end of the thread is positioned between the base 2 and the collar 3, whereon the thread is wound for a few more turns. Then, a presser of the winding machine - marked by line P in figure 2 - is released by pressure against the base 2. The pressure S of the presser P is sufficient to break the staples 4; the base 2 thus moves towards the collar 3, against which it presses.
  • the base 2 moves beyond the rib 5, by sliding of the rim 2a over the beveled surface of the saw-toothed profile.
  • the opposed portion of said saw-toothed profile then forms an abutment to stop and retain said rim 2a, so that the base 2 is firmly held against the collar 3.
  • the thread can be removed with no particular difficulties from this position of retention which, furthermore, can continue to be benefited by during normal use of the reel thread.
