ABSTRACT:
An apparatus for controlling the amount of delivery in a wrapping material feed system, including a rotation drive means for rotating a bobbin with a wrapping material wound thereon; a winding diameter detecting means for detecting a winding diameter of the wrapping material; an adjusting means for changing torque and brake forces of the bobbin to adjust the amount of delivery of the wrapping material, and a control means for controlling the adjusting means. The control means has a memory section which stores optimum torque and brake forces for winding diameters of the wrapping material as well as increment and decrement patterns of torque and brake forces for various operation modes of the wrapping material feed system, and upon receipt of a signal from the winding diameter detecting means the control means provides a signal to the adjusting means in accordance with the contents of the memory section.
