Abstract
Abstract This invention relates to a recoverable article for covering objects in which two or more cover pieces are joined together to form the article. The shape and recovery ratios of the cover pieces are chosen such that the amount of recovery does not differ by more than 20% on either side of the join line. This avoids wrinkling.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
88 words
A recoverable article for covering an object of any predetermined shape comprising a recoverable cover joined to at least one other cover along a non-linear join-line, by a mechanical joining arrangement that penetrates the cover, such that at least one of the covers has a component of recovery substantially parallel to the join-line and such that at effective complete recovery of the article, the difference between the percentage recovery of each cover on either side of the join-line, measured parallel to the join-line, is not more than 20%.
Claim 2
Dependent Claim
88 words
A recoverable article for covering an object of any predetermined shape comprising a recoverable cover joined to at least one other cover along a non-linear join-line, by a mechanical joining arrangement that penetrates the cover, such that at least one of the covers has a component of recovery substantially parallel to the join-line and such that at effective complete recovery of the article, the difference between the percentage recovery of each cover on either side of the join-line, measured parallel to the join-line, is not more than 20%.
Claim 3
Dependent Claim
16 words
An article according to claim 1, wherein the join-line is non-linear and extends in 3 dimensions.
Claim 4
Dependent Claim
18 words
An article according to claim 1, wherein at least one cover is unfoldable into a substantially flat configuration.
Claim 5
Dependent Claim
15 words
An article according to claim 1, wherein the recoverable cover comprises a heat recoverable fabric.
Claim 6
Dependent Claim
31 words
An article according to claim 1, wherein the cover is joined to at least one other cover by a mechanical joining arrangement comprising on or more of stitching, stapling or riveting.
Claim 7
Dependent Claim
16 words
An article according to claim 1, wherein the percentage recovery difference is not more than 10%.
Claim 8
Dependent Claim
16 words
An article according to claim 6, wherein the percentage recovery difference is not more than 5%.
Claim 9
Independent Claim
101 words
A method of covering an object of any predetermined shape comprising: (a) selecting at least two covers, at least one of which is recoverable; (b) joining the covers along a non-linear join-line, by a mechanical joining arrangement that penetrates the covers, such that at least one of the covers has a component of recovery substantially parallel to the join-line; (c) recovering the covers; the selecting of the covers being such that at effective complete recovery the difference between the percentage recovery of each cover on either side of the join-line, measured parallel to the join line, is not more than 20%.
Claim 10
Independent Claim
101 words
A method of covering an object of any predetermined shape comprising: (a) selecting at least two covers, at least one of which is recoverable; (b) joining the covers along a non-linear join-line, by a mechanical joining arrangement that penetrates the covers, such that at least one of the covers has a component of recovery substantially parallel to the join-line; (c) recovering the covers; the selecting of the covers being such that at effective complete recovery the difference between the percentage recovery of each cover on either side of the join-line, measured parallel to the join line, is not more than 20%.
