ABSTRACT:
A bobbin for dyeing spools possesses an openwork wall on which is wound the yarn for forming the spool, and comprises a plurality of rings (3) which are mutually connected by a series of inclined bridges (5), of greater length than the interspace between contiguous rings (3) and are deformable under the action of the axial compression of the bobbin. The length of the bridges (5) is less than the interspace between two contiguous bridges (5) of a single series of bridges for connecting two consecutive rings (3).
