  • Patent number: 7114527
    Abstract: A method achieves highly constant energy in the operation of a loom and shedding machine with separated drive technology, and ensures the run-up in one weft insertion for the loom and if necessary also for the shedding machine. The control arrangement controlling the electric motor drive of the loom and shedding machine includes a computer arrangement which, depending on machine and/or weaving technical data, determines the applicable size of the moment of inertia of a non-inherent inertial mass with which at least the shedding machine is to be equipped, and the at least one non-inherent inertial mass is arranged in such a manner, so that the determined size of the moment of inertia becomes effective in the operation of the shedding machine.

  • Patent number: 6962171
    Abstract: A drive arrangement is constructed for permitting the separate operation of a weaving machine and a shed forming machine. The drive arrangement compensates any r.p.m. variations of the weaving machine drive and of the shed forming machine relative to the drive shaft of the respective machine. This drive arrangement permits keeping the energy drawn from the electrical supply network during the start phase and the drive power to be provided for a normal operation of the weaving machine and of the shed forming machine optimally low.

  • Patent number: 6953063
    Abstract: A method of operating a weaving machine and a shedding machine aims, to achieve so-called soft starts and soft stops, in particular, of the shedding machine. The weaving machine is equipped with an electromotive main drive and the shedding machine is equipped with an electromotive auxiliary drive. In the method the shedding machine is started at a time point (t1) that lies before the starting time point of the weaving machine, and, upon a triggered interruption of the weaving process, a shedding machine comes to the standstill at a time point (t5) that lies after the standstill time point (t4) of the weaving machine.

  • Patent number: 6913044
    Abstract: A direct drive for a loom reed includes a linear motor carrying out a linear oscillating motion, or an arc segment motor carrying out a pivoting oscillating motion, or a circular coaxial motor carrying out a pivoting oscillating motion. The circular coaxial motor has a hollow shaft rotor arranged within a hollow shaft stator, and may further have an additional hollow shaft stator arranged within the rotor in a sandwich motor construction. The arc segment motor and the linear motor may similarly have a rotor member sandwiched between two stator members. Two motor units can be provided respectively above and below the weaving plane to drive the reed together. With these measures, the driving force is increased, yet the drive arrangement is confined to the available installation space.
