ABSTRACT:
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.
