Application No. 10/075,786
Claim 40 reads as follows:
An abrasion-resistant rope that must be periodically moved or pulled
across abrasive services comprising an outer protective layer formed
substantially from high performance yarns having a tensile modulus equal to or
greater than 150 grams/denier and a tenacity equal to or greater than 7
grams/denier so that the protective layer is abrasion-resistant, cut-resistant, and
tear-resistant.
Ratigan's invention relates to the protection of synthetic rope from abrasion, more
specifically chafe abrasion of synthetic marine mooring and anchor rope. Ratigan's
chafe protection device consists of a piece of textile material made of synthetic fiber,
like nylon, or polypropylene, or polyester, or acrylic. Referring to Figures 1-3, the chafe
protection device comprises a section of material, consisting of synthetic fiber material
on one side 1 and latex mat backing on the reverse side 2. Permanently attached to the
longitudinal borders of the latex mat surface material 2 are continuous strips of
VELCRO® hooks 3 and 4. To cover a rope with the protective device, either of the
longitudinal strips, 3 or 4, are placed on and in longitudinal alignment with the rope 5.
The protective material is then wrapped tightly by hand around the rope. A completed
wrap is shown in Figure 4. Unraveling of the protective device from the rope is
prevented by the remaining longitudinal strip of VELCRO® hooks, 3 or 4 which bind with
the fiber material 1 of the protective device.
