Abstract
Abstract A textile treatment sleeve has a shell, which may be cylindrical or conical. The shell has peripherally extending rings which are spaced-apart and which are axially yielding. The rings are connected by spaced-apart webs which are rigid and extend longitudinally. Axially consecutive webs are laterally offset relatively to one another.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
56 words
A sleeve of thermoplastic material for treatment of textile threads and yarns having a shell, wherein the shell comprises peripherally extending, spaced-apart rings which are elastically and plastically yielding in the axial direction of the shell, and spaced-apart rigid longitudinal webs connecting the rings, the axially consecutive longitudinal webs being laterally offset relative to each other.
Claim 2
Dependent Claim
56 words
A sleeve of thermoplastic material for treatment of textile threads and yarns having a shell, wherein the shell comprises peripherally extending, spaced-apart rings which are elastically and plastically yielding in the axial direction of the shell, and spaced-apart rigid longitudinal webs connecting the rings, the axially consecutive longitudinal webs being laterally offset relative to each other.
Claim 3
Dependent Claim
49 words
A sleeve as claimed in claim 1, wherein the rings are equidistantly spaced-apart along the axis of the shell and the longitudinal webs are equidistantly spaced-apart transversely around the shell and the axially consecutive longitudinal webs are offset relative to each other by one half of the transverse spacing.
Claim 4
Dependent Claim
37 words
A sleeve as claimed in claim 1, wherein the rings are of corrugated configuration with kinking and bending points to serving to improve their yieldingness, the longitudinal webs being connected to the said kinking and bending points.
Claim 5
Dependent Claim
54 words
A sleeve as claimed in claim 3, wherein the rings are of zigzag configuration and the section of each ring between two transversely consecutive longitudinal webs has two legs forming an angle, to the apex of which is connected an axially consecutive longitudinal web and which is directed oppositely to the connected longitudinal web.
Claim 6
Dependent Claim
16 words
A sleeve as claimed in claim 1, wherein the rings and the longitudinal webs are integral.
