ABSTRACT:
A spool for winding yarns, particularly suited for dyeing and similar operations, which may be compressed in a controlled way. The spool comprises a body having a longitudinal axis and a plurality of coaxially arranged annular members joined by yielding spacing elements; the spacing members extend in a mainly inclined direction with respect to the spool axis, flush to said annular members to define a yarn winding surface. The body furthermore comprises longitudinal stiffening members having breakable stop portions protruding from adjacent annular members to define stop means allowing an axially controlled compression of the body of the spool.
