An elevator includes said rope terminal arrangement. ## Claims ### Claim 1 A rope terminal arrangement of an elevator, comprising: a belt-shaped hoisting rope; and a gripping device arranged to grip a rope section of the belt-shaped hoisting rope via a first and a second gripping face facing each other and set against opposing first and second sides of the rope section placed in a gap between them, the gripping device comprising: a wedge frame delimiting a wedge-shaped space in which said rope section is placed; a first gripping member in the wedge-shaped space, the first gripping member having said first gripping face set against the first side of said rope section, said first gripping face being provided with an uneven surface pattern for facilitating grip between said first gripping face and said first side of the rope section; and a first wedge member wedged in the wedge-shaped space between the wedge frame and the first gripping member such that the first wedge member wedges the first gripping member to press with said first gripping face against the first side of the rope section. ### Claim 2 (depends on 1) The rope terminal arrangement according to claim 1, wherein the first gripping member and the rope section are pre-fixed together before placing the first gripping member and the rope section in the wedge-shaped space. ### Claim 3 (depends on 1) The rope terminal arrangement according to claim 1, wherein the first gripping member is mounted on the first wedge member immovably in the longitudinal direction of the rope section. ### Claim 4 (depends on 1) The rope terminal arrangement according to claim 1, wherein the first gripping member is made of different material than said first wedge member. ### Claim 5 (depends on 1) The rope terminal arrangement according to claim 1, wherein the rope section is straight, and thereby not bent into an arc, and the first and second gripping faces are also straight and parallel with the longitudinal direction of the rope section. ### Claim 6 (depends on 1) The rope terminal arrangement according to claim 1, wherein said uneven surface pattern is a knurling pattern. ### Claim 7 (depends on 1) The rope terminal arrangement according to claim 1, wherein said uneven surface pattern is a diamond knurling pattern or a straight knurling pattern. ### Claim 8 (depends on 1) The rope terminal arrangement according to claim 1, wherein a majority of the contact area formed between the first gripping face and the first side of the rope section is established via the uneven surface pattern. ### Claim 9 (depends on 1) The rope terminal arrangement according to claim 1, wherein said uneven surface pattern covers at least a majority of the first gripping face. ### Claim 10 (depends on 1) The rope terminal arrangement according to claim 1, wherein said uneven surface pattern comprises a plurality of protrusions protruding into the surface material of the rope section, and a plurality of grooves between the plurality of protrusions. ### Claim 11 (depends on 10) The rope terminal arrangement according to claim 10, wherein said grooves are between the protrusions in a longitudinal direction of the rope section. ### Claim 12 (depends on 1) The rope terminal arrangement according to claim 1, wherein a height of said protrusions is less than 2.0 mm. ### Claim 13 (depends on 1) The rope terminal arrangement according to claim 1, wherein the rope comprises an elastic coating forming the outer surface of the rope. ### Claim 14 (depends on 1) The rope terminal arrangement according to claim 1, wherein said rope comprises one or more load bearing members embedded in an elastic coating forming the outer surface of the rope, which one or more load bearing members extend parallel to the longitudinal direction of the rope unbroken throughout the length of the rope. ### Claim 15 (depends on 14) The rope terminal arrangement according to claim 14, wherein said one or more load bearing members is/are made of composite material comprising reinforcing fibers embedded in polymer matrix. ### Claim 16 (depends on 1) The rope terminal arrangement according to claim 1, wherein the gripping device comprises: a second gripping member in the wedge shaped space, the second gripping member having said second gripping face set against the second side of said rope section, said second gripping face being provided with an uneven surface pattern for facilitating grip between said second gripping face and said second side of the rope section; and a second wedge member wedged in the wedge shaped space between the wedge frame and the second gripping member such that the second wedge member wedges the second gripping member to press with said second gripping face against the second side of the rope section. ### Claim 17 (depends on 1) An elevator, comprising the rope terminal arrangement as defined in claim 1 fixing an end of a hoisting rope of the elevator immovably to a fixing base. ### Claim 18 (depends on 1) The rope terminal arrangement according to claim 1, wherein a height of said protrusions is within a range 0.5 mm-1.5 mm. ### Claim 19 (depends on 14) The rope terminal arrangement according to claim 14, wherein said one or more load bearing members is/are made of composite material comprising reinforcing fibers embedded in polymer matrix, said reinforcing fibers being carbon fibers. ### Claim 20 (depends on 2) The rope terminal arrangement according to claim 2, wherein the first gripping member is mounted on the first wedge member immovably in the longitudinal direction of the rope section.
