Abstract: An axially-compressible coil carrier comprising first and second parallel, coaxial end rings, a plurality of carrier rings positioned between the first and second end rings, and a plurality of support struts arranged in rings, the rings of struts alternating with the carrier rings, and neighboring carrier rings being joined to each other by one of the rings of support struts. The carrier rings are parallel to and coaxial with each other and with the first and second end rings, and are separated by an inside distance of between about 5 mm and about 12 mm. The struts in each of the rings are divided into first and second groups. The struts in the first group are spaced equidistantly around the circumference, and are alternated with pairs of struts of the second group. The struts of the second group are generally parallel to their neighboring struts of the first group to form triads of parallel struts, the struts in each the triad being equidistantly spaced.

Abstract: A coil carrier compressible in axial direction, for the heat and wet treatment of threads and yarns, with a cylindrical or fruits-shaped winding surface, incorporates carrier rings (1;26) whose cross-sections are tapered radially outwards, and which are configured coaxially to one another. Neighbouring carrier rings (1;26) are joined together by struts (9;16;27). Facing limiting stops (11,12;20;28;29) are provided on the facing surfaces of neighbouring carrier rings (1;26), whereby the faces (13,14;21) of these limiting stops are oriented in radial direction normal to the axis of the coil carrier. The faces (13, 14;21) interlock directly or, alternatively, each face acts together with one functional surface (18,19) of an intermediate element (17) installed between the limiting stops. (FIG.
