(new) A b s t r a c t This invention relates to a compressible cheese centre for dyeing purposes, comprising two end rings and a plural- ity of intermediate stiffening rings (12, 14 and 16) connected together by springy webs (18). Belonging to the state of the art is a cheese centre (US 3 753 534) in which the webs are bent at rightangles and joined at rightangles to the rings and all the webs and stiffening rings form a cylindrical envelope on their external surface. There has also been disclosed (DE 75 16 449, Figs.5 and 6) a cheese centre having spacer lugs cooperating pairwise situated between the rings which are connected together by S-shaped webs whose middle sections can be clamped between the pairs of lugs. A disadvantage of the first cheese centre is that textile fibres or threads wound on to the centre for dyeing purposes are liable to be clamped between the webs and rings of the centre when the latter is under axial compression and are thereby liable to be damaged. It is an object of the present invention to protect the textile material when the cheese centre is under compression. The solution to this problem is provided by spacer lugs (34) arranged pairwise between webs (18) which are adjacent to one another in the circumferential direction of the cheese centre so that the lugs (34) of each pair meet when they approach one another in the axial direction. The advantage of this solution is that it prevents parts of the web from abutting against the adjacent ring when compression is too high. Such abutment could cause breakage of the web as well as clamping of the fibres or threads. Fig.1 is the main figure.
