Flexible protective sleeve

摘要

A flexible protective sleeve (10; 32 to 37) comprises a supporting layer (11) formed from a strip (12) which has the general shape of a helix having a gap (14) between successive turns thereof. The sleeve (10; 32 to 37) also comprises a bridging layer (16) which is supported by said supporting layer (11) and bridges said gap (14). The bridging layer (16) is formed from flexible sheet material (18; 48) which is arranged to deform to allow said gap (14) to locally change in width to accommodate deformations of the sleeve.
