The invention concerns a frame comprising two posts (4, 4') and two cross-members (6, 6'), a catching member (8, 8') adapted to receive one corresponding end of at least one heald (10), and damping means (12, 12') against which at least one end of the heald is urged to be pressed. At least when the frame is stationary, the heald being substantially rectilinear, when one first end of the or each heald (10) is pressed, either on a first catching member (8) at the traction zone (S1) thereof, or on a first damping means (12) at the compression zone (C1) thereof, the other end of the or each heald (10) is pressed, either on other damping means (12') at the compression zone (C'1) thereof, or on another catching member (8') at the traction zone (S'1) thereof. |
