Patent ID: 7900306

Claim:
Guiding device ( 1 ) for strands ( 2 ), the guiding device ( 1 ) comprising a body ( 5 ) in which at least one curved channel ( 6 ) is made, including a longitudinal axis ( 7 ) defining a plane of curvature ( 12 ), is curved according to the curvature of said channel ( 6 ) and: at least one first part ( 8 ) which is positioned at the side of the intrados of the longitudinal axis ( 7 ), permits, within the limit of the length of the channel ( 6 ), the support of the strand ( 2 ) on at least a portion of the peripheral face ( 10 ) of said strand ( 2 ), this device being characterized in that the first part ( 8 ) has a first cross section which is delimited by at least two faces of lateral support, referred to as first faces ( 13 ), wherein the first faces ( 13 ) are: situated in such a way as to be able to co-operate locally with the part of the strand ( 2 ) which is engaged in the channel ( 6 ), and forming two lateral zones ( 14 ) of its peripheral face ( 10 ) which are situated on the both sides of the plane of curvature ( 12 ), oriented in such a way as to form between the first faces an angle (“A”) predetermined at least sufficiently to initiate a phenomenon of clamping of the strand ( 2 ) when it receives a stress.
