In order to make a small space requirement, a low energy requirement and therefore an increased weaving frequency possible in a shedding apparatus, a spring drive is proposed which is connected to magnetically acting holding means. The holding means are capable of holding the heddle frame in an upper shed position and in a lower shed position counter to the spring force. Furthermore, the heddle frame is connected to a linear motor. A heddle movement can be initiated by said linear motor. According to the invention, the spring drive is configured as a tension/compression spring which is designed in such a way that, during operation of the heddle frame at the resonant frequency of the spring drive the greater part of the kinetic energy can be obtained from the spring drive.

An electronic jacquard plate features that a permanent magnet and an insulating layer and arranged on the top of electromagnet to decrease the time and amplitude of current flowing in the winding of electromagnet, resulting in less heat generation, high reliability and long service life.

The invention discloses an electronic jacquard card needle-selection drive board which comprises a drive circuit board, a bistable needle selection electromagnetic valve, an FPC flexible circuit and at least two fixed pins, wherein an electromagnetic valve fixed seat for the bistable needle selection electromagnetic valve is provided with locating posts; the drive circuit board is provided with locating holes which cooperate with the locating posts; the electromagnetic valve fixed seat is provided with pin holes which cooperate with the fixed pins; the drive circuit board is provided with fixing holes which cooperate with the fixed pins and the pin holes; the electromagnetic valve fixed seat and the drive circuit board are fixed together through the fixed pins; the FPC flexible circuit comprises a flat cable terminal and an FPC connector; the FPC connector is welded on the drive circuit board; and the flat cable terminal cooperates with the slot of the FPC connector.
