Abstract
Abstract A wrap-around sleeve, for enclosing and protecting an object such as a wire bundle, comprises a plain weft-knitted sheet formed from a filament having an elastic modulus such that the sheet has a sufficiently high transverse curl force (which is the force with which the sheet tends to curl transversely) that the sleeve remains wrapped around the object without separate closure means. Preferably the elastic modulus of the filament is at least 4000 N.mm -2 .

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
44 words
A wrap-around sleeve comprising a plain weft-knitted sheet formed from at least one filament having an elastic modulus such that the sheet has a sufficiently high transverse curl force (as herein defined) that the sleeve remains wrapped around an object without separate closure means.
Claim 2
Dependent Claim
44 words
A wrap-around sleeve comprising a plain weft-knitted sheet formed from at least one filament having an elastic modulus such that the sheet has a sufficiently high transverse curl force (as herein defined) that the sleeve remains wrapped around an object without separate closure means.
Claim 3
Dependent Claim
22 words
A sleeve as claimed in claim 1, in which the elastic modulus of the filament is at least 4000 N.mm -2 .
Claim 4
Dependent Claim
29 words
A sleeve as claimed in claim 1, in which the width of each wale is less than 2.5 mm over a substantial part of the width of the sheet.
Claim 5
Dependent Claim
26 words
A sleeve as claimed in claim 1, in which the sheet has at least 5 courses per cm length over a substantial part of its length.
Claim 6
Dependent Claim
27 words
A sleeve as claimed in claim 1, in which each stitch in a substantial portion of the sheet comprises from 8 to 12 mm of the filament.
Claim 7
Dependent Claim
43 words
A sleeve as claimed in claim 1, in which over at least a portion of the length of the sheet, the width of at least one wale is a multiple of the width of each of a substantial number of the other wales.
Claim 8
Dependent Claim
38 words
A sleeve as claimed in claim 6, in which the multiple width wale is produced by knitting the sheet on an array of regularly spaced needles of which at least one is not used to form a stitch.
Claim 9
Dependent Claim
27 words
A sleeve as claimed in claim 7, in which the needle not used to form a stitch is the third needle from an end of the array.
Claim 10
Dependent Claim
23 words
A sleeve as claimed in claim 7, in which the needle not used to form a stitch is substantially central in the array.
Claim 11
Dependent Claim
19 words
A sleeve as claimed in claim 1, in which the sheet is slit along a portion of its length.
Claim 12
Dependent Claim
23 words
A sleeve as claimed in claim 1, in which at least a portion of the sheet is formed from two filaments knitted together.
Claim 13
Dependent Claim
29 words
A knitted wrap-around sleeve having a transverse curl force (as herein defined) of at least 3 grams force per mm length and a knitted closure portion formed integrally therewith.
Claim 14
Dependent Claim
29 words
A knitted wrap-around sleeve having a transverse curl force (as herein defined) of at least 3 grams force per mm length and a knitted closure portion formed integrally therewith.
Claim 15
Dependent Claim
23 words
An elongate article which is enclosed along at least a part of its length by a wrap-around sleeve as claimed in claim 1.
Claim 16
Dependent Claim
13 words
An elongate article as claimed in claim 13, which comprises a wire bundle.
