Abstract
A fibrous closure comprises a dimensionally stable, heat resistant fibrous backing layer and a layer of high shear strength pressure sensitive adhesive. The closure is used in conjunction with a heat shrinkable, wraparound sleeve for sealing cable jackets, connectors and joints between lengths of pipe or other elongate objects. The sleeve is wrapped around the object such that its ends overlap. The closure is then applied over the overlapping ends of the sleeve to prevent slippage of the overlapping ends during heat shrinking, and to prevent subsequent creeping of the overlap joint due to hoop stresses in the shrunken sleeve. The closure avoids use of a relatively inflexible polymeric backing layer, and is therefore able to conform to objects having a relatively small diameter or irregular shape.
