Patent ID: 8141593

Claim:
A system for tightly covering an elongate member ( 25 ; 225 ) of predetermined dimensions with an elastic protection sleeve ( 11 ; 111 ; 211 ; 311 ), comprising: said sleeve ( 11 ; 111 ; 211 ; 311 ); a tubular core ( 12 ; 112 ; 212 ; 212 ′; 312 , 312 ′) for keeping in an elastically stretched condition said sleeve ( 11 ; 111 ; 211 ; 311 ) tightly covered by said sleeve, and adapted to receive inside said sleeve said elongate member ( 25 ; 225 ); and a film ( 13 ; 113 ; 213 , 213 ′; 313 , 313 ′) with a low coefficient of friction placed between said sleeve ( 11 ; 111 ; 211 ; 311 ) and said core ( 12 ; 112 ; 212 , 212 ′; 312 , 312 ′) to enable said core to slide relative to said sleeve, said film extending at least from one end ( 15 ; 115 ; 215 , 216 ; 315 , 316 ) of the sleeve to a first end ( 17 ; 117 ; 217 , 217 ′; 317 , 317 ′) of the core opposite said end of the sleeve; wherein a second end ( 18 ; 118 ; 218 , 218 ′; 318 , 318 ′) of the core ( 12 ; 112 ; 212 , 212 ′; 312 , 312 ′) is situated beyond said end ( 15 ; 115 ; 215 , 216 ; 315 , 316 ) of the sleeve ( 11 ; 111 ; 211 ; 311 ), and said low friction coefficient film ( 13 ; 113 ; 213 ; 213 ′; 313 , 313 ′) makes a half-turn at said first end ( 17 ; 117 ; 217 , 217 ′; 317 , 317 ′) of the core ( 12 ; 112 ; 212 , 212 ′; 312 , 312 ′) and then extends inside said core as far as its second end ( 18 ; 118 ; 218 , 218 ′; 318 , 318 ′) at which said film makes a half-turn and then extends outside the core as far as said sleeve ( 11 ; 111 ; 211 ; 311 ) to which said film is fixed externally.
