System for tightly covering an elongate member with an elastic protection sleeve

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.
