Abstract
The invention relates to a method and to a device for implementing the method for tensioning an inextensible or substantially inextensible longitudinal strap (12) comprising a distal end portion (15) and a proximal end portion (11), each end portion being respectively fixed to a corresponding attachment point (13, 16). The method is characterized in that a cycle (2) of successive transverse pressure applications is exerted on the strap (12), comprising a first transverse pressure application (23) on a first portion (20) of die strap then a second (24) and a third (25) transverse pressure application on a second (21) and a third (22) portion of the strap, respectively.
Claims19
A method for tensioning an inextensible or substantially inextensible longitudinal strap (12) comprising a distal end portion (15) and a proximal end portion (11), each end portion being respectively fixed to a corresponding anchor point (13, 16), characterized in that a cycle (2) of successive applications of transverse pressure to the strap (12) is applied, this cycle comprising a first application (23) of transverse pressure to a first portion (20) of the strap, followed by a second (24) and a third (25) application of transverse pressure to a second (21) and to a third (22) portion of said strap respectively.
A device (27) for tensioning an inextensible or substantially inextensible strap (12) extending longitudinally between a distal end portion (15) and a proximal end portion (11) which are respectively fixed to corresponding anchor points, characterized in that it comprises thruster means (43, 44, 45;
- 46, 47, 48;
- 49, 50) for applying transverse pressure to the strap, comprising first thruster means (44, 47) for applying transverse pressure to a first portion (20) of strap, second (43, 46) and third (45, 48) thruster means for applying transverse pressure to a second (21) and to a third (22) portion of strap respectively, and control means controlling said pressure-application thruster means and designed to perform at least one cycle of successive applications of pressure to the strap (12) on said first, second and third portions of said strap in a determined manner.
