  • Patent number: 6105630
    Abstract: An electrical rotating apparatus for controlling a harness cord associated with the shed of a weaving loom which includes an actuator including a rotor and a stator. The rotor is formed of at least two permanent magnets which are mounted within a tube so as to be spaced axially with respect to one another and wherein a plurality of stator elements are also provided offset axially relative to an axis of rotation of the rotor such that each of the plurality of rotors corresponds with a separate one of the plurality of stators. The polarities of one or the other of the permanent magnets or the stator elements are offset angularly relative to the axis of rotation.

  • Patent number: 6105629
    Abstract: A housing for the removable positioning of one or more rotary electric actuators used for formation of the shed of a weaving loom and which housing includes at least one compartment which allows the actuators to be received and removed therefrom by movement in a direction parallel to an axis of rotation of rotary elements associated with the actuators and which elements control the movement of the harness cords of the shed forming device. The housing allows harness threads to be moved relative thereto with respect to the rotary elements and may include a cover to encase the rotary elements associated with the actuators.

  • Patent number: 6050305
    Abstract: A locking mechanism for a rotary electric actuator for the formation of a shed on a loom wherein the actuator includes a driving rotor for rotating a device for winding and unwinding a harness thread and wherein the actuator includes a locking plate driven by the rotor which interacts with a locking member such that, when a stop of the locking member engages the locking plate, rotation of the rotor is stopped. A control mechanism is provided to selectively maneuver the locking member relative to the locking plate.

  • Patent number: 5435353
    Abstract: In a Jacquard system, in order to form an oblique shed necessary for the weaving of ribbon-like articles drums whose diameters decrease from one end of the system to the other are provided. The drums are used for driving the runs of funicular elements which bear the knives for actuating the hooks of the modules which house the cords for vertical control of the warp yarns. The drums are driven with oscillating movement by two longitudinal connecting rods.

  • Patent number: 4387741
    Abstract: The present invention relates to the system of angular connection of the eccentric of each element of a dobby either with the shaft or with the corresponding arm. This connection is ensured by a double hook borne by the eccentric and mounted to rock so that one or the other of its noses engages in a notch made in the periphery of a driving device fixed to the shaft, or in a notch in a bead of the arm.
