The invention relates to a bending device for producing bent plastic tubes by thermoforming, the tubes being inserted into the guide duct of forming templates (2a-2d). According to the invention, this bending device comprises at least three workstations (11-14) intended to take identical forming templates and comprising circulation means (18-20) designed to form a thermoforming fluids circulation circuit incorporating the tube borne by the forming template (2a-2d), a multi-articulated robotised system (28, 29) comprising a gripper (31) provided with a press member having a bearing surface able to apply to a tube a force that inserts said tube into the guide duct of the forming templates (2a-2d), and means for the relative displacement of the robotised system (28, 29) and workstations (11-14) which are designed so that said robotised system is positioned facing each of said workstations in succession. |
