Abstract
A recoverable tubular article comprising an elastomeric sleeve held in an expanded or extended condition and capable of recovering to its unexpanded condition of smaller diameter upon the removal of an outer restraint, an outer restraint, essentially tubular in configuration, bonded to said elastomeric sleeve, said restraint and said bond between the sleeve and the restraint being sufficiently strong to retain the elastomeric sleeve in its expanded condition under ordinary conditions of storage and said restraint being capable of being segmented and peeled from said elastomeric sleeve to permit said sleeve to recover to its original state.

A recoverable tubular article comprising:
- a recoverable tubular sleeve held under tension in a radially expanded condition by an essentially tubular restraint disposed about and in bonded relationship to the radially outward exterior of said sleeve;
- said restraint being capable of being mechanically segmented so as to release said tension and permit recovery of said sleeve and being sufficiently rigid in its unsegmented condition to maintain said sleeve in the expanded, recoverable condition.
A recoverable tubular article comprising:
- a recoverable tubular sleeve held under tension in a radially expanded condition by an essentially tubular restraint disposed about and in bonded relationship to the radially outward exterior of said sleeve;
- said restraint having weakened portions such that it is capable of being mechanically segmented by peeling so as to release said tension and permit recovery of said sleeve and being sufficiently rigid in its unsegmented condition to maintain said sleeve in the expanded, recoverable condition.
A recoverable tubular article comprising:
- a recoverable tubular sleeve held under tension in a radially expanded condition by an essentially tubular restraint disposed about and in bonded relationship to the radially outward exterior of said sleeve;
- said restraint being comprised of a frangible material capable of being mechanically segmented by being fractured so as to release said tension and permit recovery of said sleeve and being sufficiently rigid in its unfractured condition to maintain said sleeve in the expanded, recoverable condition.
