Abstract
Abstract A heat-recoverable wrap-around device is made from heat-shrinkable sheet material, two opposed edges of which may be secured together by fasteners so as to form a sleeve prior to recovery. Each edge region is provided with a strip of rigid material lying generally in the plane of the sheet. The strips may be bonded or embedded within the sheet material, or positioned in terminal loops therein, and are preferably so designed that they can be deformed into an interlocking relationship which withstands the recovery forces.

Total Claims: 30
Claim 1
Independent Claim
100 words
A heat-recoverable wrap-around device made from heat-recoverable sheet material, wherein two opposed edge regions of the sheet material which are securable together by a fastening means to form a sleeve prior to recovery are each provided with a strip of relatively rigid material, the strips lying generally in the plane of the heat-recoverable sheet material and having end portions extending beyond the sides of the sheet material which end portions are capable of being engaged with each other and/or one or more other members at or beyond the sides of the heat-recoverable sheet material to form the fastening means thereof.
Claim 2
Dependent Claim
100 words
