Abstract
This weft insertion system includes at least one rapier (6, 8) provided with weft yarn clamping means (622, 822) for drawing a weft yarn (202) and a reed (2) provided with dents (22) made of a magnetic material. The rapier (6,8) is equipped with magnetic means for exerting an attractive magnetic effort (E, E′) between this rapier and the dents of the reed. The reed (2) advantageously has a variable magnetic permeability along its longitudinal axis (X2). The rapier (6, 8) has a lateral face (8262) oriented towards the reed (2) and the magnetic means have a direction of polarization perpendicular to the direction of travel (X6, X8) of the rapier and secant with this surface (8262).
