Abstract

This invention relates to a warp knitting machine in which the knitting elements and each of the warp beams are driven by separate electric motors, powered from a common electrical network. An electric clutch is included in the drive connection between each warp beam and its electric motor and said clutch is energized by the same electric network which powers the electric motors. The electric clutch is energized when electric current is supplied to it by the network and connects the warp beams with their own electric motors. Whenever the electric current in the network is interrupted, the electric clutch is disengaged.
