Abstract (en)
Under normal running, the gripper clip (20) is opened by the movement of the end of the lever (21) over the cam (24), the timing being altered by adjusting the position of the cam in the direction (B) by means of a drive (28, 29). During slow running of the loom, the lever (21) is moved by displacing the cam (24) at right angles in the direction (C) by means of a drive (30). Opening of the clip (20) is then under the control of a sensor for the position of the gripper (3) acting on the drive (30). An independent claim is also included for an arrangement for opening the gripper clip (20), including electrical drives (26, 30) and sensors to indicate the position of the grippers. During slow running of the loom the cam (24) is moved towards the lever (21) to open the clip (20) at a predetermined position of the gripper. Preferred Features: Separate electric motors and cranks (28, 29, 32, 33) are provided for the two motions in the directions (B) and (C).
