ABSTRACT:
A sleeve for use in the treatment of textile threads and yarns including dyeing having a shell wherein the shell comprises peripherally extending spaced apart rings which are elastically yielding in the axial direction of the shell and spaced-apart webs which are elastically yielding in the axial direction of the shell, connecting the rings, the axially consecutive webs being laterally offset relative to each other whereby when the rings and webs are yielding, the rings become serpentine and the webs become bowed, at least selected ones of the webs being adapted to bow in a selected common direction generally circumferential with respect to the sleeve to ensure substantially uniform displacement of the sleeve members, thus to provide a sleeve having minimum restriction for passage of dye and which sleeve is substantially rigid in yielded or non-yielded state. In a further embodiment a similar sleeve is provided wherein the webs are grouped in pairs to provide axially consecutive pairs of webs laterally offset relative to each other whereby when the rings and the webs are yielding in response to axial compression of the sleeve, the rings become serpentine and the webs become bowed. In still a further embodiment, a sleeve similar to the first mentioned is provided wherein the axially consecutive webs being laterally offset relative to each other are all adapted to yield uniformly during compression of the sleeve, as for example during a dyeing operation.
