  • Device for automatically varying the position of the shed vertex in a loom
    Patent number: 5386855
    Abstract: A device for automatically varying, during the transient states following loom stoppages, the shed vertex position in the loom. The device consists of a sensor for determining the beat-up pulse intensity of the loom reed. The device also is connected to a comparator which receives a predetermined set value corresponding to the beat-up pulse intensity of the reed during normal operation. The output of the comparator is used, through a control unit, to synchronously drive the electric motors that operate the beam and the take-up roller of the loom, respectively.
