Abstract
Abstract An assembly for sealing and protection of cable splices comprising a recoverable, preferably heat-recoverable, outer sleeve (5) surrounding a cable or other body (1); a thermoplastic support layer (7) surrounding the body (1) and within the sleeve (5); and a heat barrier layer, preferably foamed, between the support (7) and the sieve (5), to prevent thermal deformation of the support (7) during heat recovery of the sleeve (5) or during other heat treatment.

A recoverable closure assembly, comprising a recoverable outer sleeve (5) which can surround a body (1) to be enclosed thereby, and a liner (3) which can surround the body (1) within the sleeve (5), characterised in that the liner (3) in use comprises an internal thermoplastic support layer (7) and an external heat barrier layer (6).
Claim 2
Dependent Claim
56 words
A recoverable closure assembly, comprising a recoverable outer sleeve (5) which can surround a body (1) to be enclosed thereby, and a liner (3) which can surround the body (1) within the sleeve (5), characterised in that the liner (3) in use comprises an internal thermoplastic support layer (7) and an external heat barrier layer (6).
Claim 3
Dependent Claim
23 words
An assembly according to Claim 1, characterised in that each layer of the liner (3) is substantially incapable of capillary transfer of liquid.
Claim 4
Dependent Claim
43 words
An assembly according to Claim 1 or 2, characterised in that the sleeve (5) is heat recoverable, and the heat barrier layer (6) is capable in use of preventing thermal deformation of the support layer (7) during heat recovery of the sleeve (5).
Claim 5
Dependent Claim
57 words
An assembly according to Claim 3, characterised in that the time and temperature required for recovery of the sleeve (5), the heat transfer rate of the heat barrier layer (6), and the heat stability of the support layer (7), are related such that on recovery of the sleeve (15) the support layer (7) substantially retains its strength.
Claim 6
Dependent Claim
22 words
An assembly according to any of the preceding claims, characterised in that the heat barrier layer (6) comprises a foamed polymeric material.
Claim 7
Dependent Claim
28 words
An assembly according to Claim 5, characterised in that the foamed polymeric material is a substantially closed cell cross-linked foam, and preferably a neoprene foam or polyolefin foam.
Claim 8
Dependent Claim
24 words
An assembly according to any of the preceding claims, characterised in that the heat barrier layer (6) is laminated to the support layer (7).
Claim 9
Dependent Claim
22 words
An assembly according to any of the preceding claims, characterised in that the support layer (7) comprises an olefinic polymer, preferably polypropylene.
Claim 10
Dependent Claim
20 words
An assembly according to Claim 8, characterised in that the support layer (7) is a calcium carbonate carbonate-filled olefinic polymer.
Claim 11
Dependent Claim
41 words
An assembly according to any of the preceding claims, charaterised in that the liner (3), in use, has tapered end portions (4) produced by bending inwardly tongues defined by adjacent longitudinal slits which extend into the end of the support layer.
Claim 12
Dependent Claim
24 words
An assembly according to Claim 10, characterised in that the support layer (7) has an enlarged hole at the closed end of each slit.
Claim 13
Dependent Claim
45 words
An assembly according to Claim 10 or 11, characterised in that the slits or holes or both the slits and the holes penetrate only the support layer (7), and do not penetrate the heat barrier layer (6) or any other layer of the liner (3).
Claim 14
Dependent Claim
33 words
An assembly according to any of the preceding claims, characterised in that the support layer (7) has longitudinal lines of weakness (12) which aid curvature of the liner (3) around the body (1).
Claim 15
Dependent Claim
60 words
An assembly according to any of the preceding claims, characterised in that the heat barrier layer (6) or another layer overlaps the support layer (7) along a longitudinal edge thereof to form a tag (13) which, when the liner (3) is in use, bonds to a portion of the liner (3) to hold the liner (3) around the body (1).
Claim 16
Dependent Claim
55 words
. An assembly according to any of the preceding claims, characterised in that the heat barrier layer (6) or another layer overlaps the support layer (7) along a longitudinal edge thereof to form a tag (13) which, when the liner (3) is in use, provides a barrier between said edge and the outer sleeve (5).
Claim 17
Dependent Claim
41 words
An assembly according to Claim 14 or 15, characterised in that the overlap is produced by removal of a longitudinal strip (14) of support layer (7) from a bonded laminate of support layer (7) and heat barrier (6) or other layer.
Claim 18
Dependent Claim
48 words
An assembly according to Claim 16, characterised in that the heat barrier (6) or other layer, as the case may be, is bonded to the support layer (7) by a pressure sensitive adhesive, such that removal of the strip (14) results in a pressure sensitive adhesive tag (13).
Claim 19
Dependent Claim
25 words
An assembly according to any of the preceding claims, characterised in that the liner (3) additionally comprises a substantially vapour impermeable moisture barrier layer (8).
Claim 20
Dependent Claim
27 words
An assembly according to Claim 18, characterised in that the support layer (7), the heat barrier layer (6) and the moisture barrier layer (8) are bonded together.
Claim 21
Dependent Claim
23 words
An assembly according to Claim 18 or 19, characterised in that the moisture barrier layer (8) comprises a foil, preferably an aluminium foil.
Claim 22
Dependent Claim

Claim 25
Dependent Claim
80 words
A liner (3) for use in an assembly according to any of Claims 1 - 19, comprising a support layer (7) bonded to another layer, characterised in that the support layer (7) has a line of weakness (12) or indentation by means of which a longitudinal strip (14) of the support layer (7) can be removed to expose a tag (13) of the other layer which can provide a covering for the resulting exposed edge of the support layer (7).
Claim 26
Independent Claim
59 words
A method of enclosing a body (1), characterised in that it comprisess positioning about the body (1) a liner (3) as defined in any of Claims 1 - 20 or as claimed in Claims 23 or 24, and a recoverable sleeve (5) as defined in any of Claims 1 - 20, and then effecting recovery of the sleeve (5).
