Abstract (en)
The present invention concerns a reel for sewing threads, of the type comprising a cylindrical body (1) having at one end a widened base (2) and a flange collar (3) close to said base. The widened base has an inner rim (2a) surrounding the cylindrical body, to which it is fixed through a plurality of breakable staples (4). Once the thread has been wound, some turns are wound between the flange and the widened base, this latter is then pressed towards the flange causing the breakage of the staples (4) and the fitting of the base into a saw-toothed rib (5) provided on the cylindrical body (1). In this way, the widened base remains in close contact with the flange and guarantees, thanks to the resiliency of this latter, a reliable means of thread retention during the automatic packaging of the reel and during use thereof.
