  • Compact Jacquard selecting card using piezoelectric elements
    Patent number: 7057329
    Abstract: A compact electronic selection card applicable for use in Jacquard equipment, having a high-density array of selecting hooks which are individually positioned by piezoelectric actuator elements. Each piezoelectric element directly controls a selecting hook for engaging a corresponding hooked rod connected to a warp yarn. The engaged rods are then lifted to form the shed. Because each element directly positions the hook rather than indirectly controlling a positioning mechanism, the selection card is mechanically simple and compact.
    Type: Grant
