ABSTRACT:
A cylindrical or conical bobbin (1) resiliently compressible both in axial and in radial direction and supporting textile strands to be subjected to a heat and/or wet treatment has an outer grating (3), the outer side of which forms the curved surface of the bobbin (1), the curved surface serving as a supporting surface for the strands. The bobbin (1) includes means (2, 2', 2", 3, 4, 5) which retain the grating (3) when the bobbin (1) is not compressed more than a predetermined length in the axial direction in such a manner that the outer surface is positioned in a radial outer position, and which release the grating (3) when the bobbin (1) is axially compressed more than a predetermined length in such a manner that the outer surface is inwardly displaceable into a radial inner position, and which prevent an additional inward displacement of the outer surface.
As a result, the bobbin (1) can maintain a constant maximum outer diameter during the winding of the strands on the bobbin and during the later handling thereof, and through a suitable, axial compression of the bobbin (1) a reduction of the outer diameter of said bobbin is obtainable in such a manner that the strands wound thereon may relax in their longitudinal direction.
