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. 1)
