  • the drive system according to the invention can be made very compact and also very rigid, so that it is subject to only slight vibrations. This allows you to work at high weaving speeds.
  • the drive system according to the invention requires relatively little space in the weaving machine, so that it is possible, for example, to arrange a weft preparation system above this drive system.

  • the housing or the partial housing with the control lever is provided with fastening means for attachment to a side part of a machine frame of the weaving machine.
  • the forces transmitted from the axis of the control lever into the partial housing are thus introduced directly into the machine frame of the weaving machine.

It is thereby achieved that the transmission of vibrations and vibrations from the machine frame to the drive system for the shedding means and the transmission of vibrations and vibrations from the drive system to the machine frame of the weaving machine are reduced.
  • Simple assembly is made possible in that, in an embodiment of the invention, the partial housing in which the at least one further lever is mounted is held on the partial housing of the control lever.
  • the two sub-housings In order to be able to connect the two sub-housings to one another such that the axis of the control lever and the axis of the further lever or levers are exactly aligned with one another, in an embodiment of the invention it is provided that the two sub-housings have reference surfaces facing one another, which are preferably each parallel to the the axis arranged in them.

  • this arrangement enables a lubrication system with lubricating oil lines and lubricating oil nozzles to be attached to the bearings of the control lever, so that these bearings can be well lubricated and also cooled.

Due to the reference surfaces, the two sub-housings can be positioned exactly in relation to each other and assembled into one unit. This ensures that the axis of the control lever and the axis of the drive lever are aligned parallel to each other and control lever and drive lever exactly cursed with each other. This orientation is retained even when effective forces and temperature changes change.
