ABSTRACT:
A compressible cheese center for dyeing purposes, has two end rings, and a plurality of intermediate stiffening rings (12, 14 and 16) connected together by springy webs (18).
Spacer lugs (34) are arranged pairwise between webs (18) which are adjacent to one another in the circumferential direction of the cheese center so that the lugs (34) of each pair meet when they approach one another in the axial direction, preventing 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.
