Abstract (en)
[origin: EP3772549A1] A drawing-in gripper (8) for drawing warp yarns of extends longitudinally along a main axis (X8) between a gripper nose (82) and a coupling rear end (84). The gripper defines a yarn-receiving cavity (86) which extends, between the gripper nose and the coupling read end, through the gripper along a transverse axis perpendicular to the main axis. The gripper forms a bite portion (88), which extends longitudinally at the rear of the gripper nose, and an entry opening (866) of the yarn-receiving cavity (86) is defined between a rear tip (882) of the bite portion and a rectilinear back surface (868) of the yarn receiving cavity. In a longitudinal plane perpendicular to the transverse axis (Y8), the yarn-receiving cavity (86) is L-shaped. An angle (β), defined between the main axis (X8) and the rectilinear back surface (868) and measured in the longitudinal plane and within the yarn-receiving cavity (86), is between 90° and 105°, preferably equal to 90°.
