  • Corrugator control system
    Patent number: 3970489
    Abstract: A system for controlling, in a corrugating operation, the amount of single face material in a storage area ahead of the double face operation, includes means for sensing the difference between single face and double face drive speeds, and for providing a signal proportional to that difference; means for sensing the amount of single face material entering and leaving the storage area and means for providing a signal proportional to the difference therebetween; means for sensing the speed of material moving adjacent the storage area input and means for sensing the speed of material moving adjacent the storage area output and means for comparing said speeds and for applying the comparison to said material comparison signal; and control means for the single face drive utilizing the speed and material proportional signals as the inputs therefor.
