  • Patent number: 4438787
    Abstract: The present invention relates to a device for selecting the hooks of a weaving mechanism by successive feeling of two half zones of a card of the Jacquard type. Said device comprises a Maltese cross having four inlets determined by two perpendicular grooves and a driver of which the two pins are located at two different radial distances from the center. In this way, the Maltese cross is subjected to two alternating angular rotations of different amplitude. The invention is particularly applicable to weaving mechanisms incremental.
