Abstract
Abstract A textile-treating sleeve made of thermoplastics material has a cylindrical or conical shell comprising consecutive rows of rigid ring sections. These ring sections extend circumferentially and are spaced apart in the axial and transverse directions. The ring sections of adjacent rows are offset relative to one another, and the ends of ring sections of adjacent rows are connected by longitudinal webs which are elastically and plastically yieldable in circumferential direction when axial and/or radial pressure is applied to the sleeve.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
36 words
A sleeve according to claim 1, wherein the ring sections and the webs are equidistantly spaced apart and the ring sections of axially consecutive rows are offset relative to each other by half their axial spacing.
Claim 2
Dependent Claim
45 words
A sleeve according to claim 1, wherein the webs are inclined to the axial direction, the inclination of the webs connected to one end of each ring section being opposite to that of the webs connected to the other end of the said ring section.
Claim 3
Dependent Claim
40 words
A sleeve according to claim 3, wherein the inclination of axially consecutive webs changes alternately, any two axially consecutive webs form an obtuse angle pointing in the direction of the end of the ring section to which they are connected.
Claim 4
Dependent Claim
21 words
A sleeve according to claim 1, wherein the connections between the webs and the ring sections constitute bending and buckling points.
Claim 5
Dependent Claim
62 words
A sleeve according to claim 1, wherein the ends of the ring sections are connected by a single web each with the ends of the ring sections of axially adjacent rows of ring sections, and wherein the webs connecting adjacent ends of ring sections of axially consecutive rows of ring sections extend continuously from one end of the sleeve to the other.
Claim 6
Dependent Claim
40 words
A sleeve according to claim 1, wherein the ring sections of adjacent axial rows of ring sections overlap in the direction of the circumference, the overlapping parts of the ring sections being interconnected by at least two parallel, spaced webs.
Claim 7
Dependent Claim
35 words
A sleeve according to claim 1, wherein the ring sections and the webs are of rectangular cross section, the thickness of the ring sections being comparatively great and that of the longitudinal webs comparatively small.
Claim 8
Dependent Claim
49 words
A sleeve according to claim 1, wherein the outer and inner edges of the ring sections form arcs of a circle and are so formed that, prior to compression of the sleeve, the ring sections form an exactly cylindrical inner surface, and after compression, an exactly cylindrical outer surface.
Claim 9
Dependent Claim
23 words
A sleeve according to claim 1, wherein the ends of the sleeve have end rings to which the webs adjacent thereto are connected.
Claim 10
Dependent Claim
18 words
A sleeve according to claim 10, wherein the ring sections, the webs and the end rings are integral.
Claim 11
Dependent Claim
11 words
A sleeve according to claim 1 made of thermoplastic synthetic resin.
