ABSTRACT:
Feed control apparatus includes a rotatable supply roll on which a supply of sheet or ribbon to be dispensed may be placed, a brake for applying variable braking force to said supply roll to prevent overrunning of the sheet or ribbon from the roll due to inertial effects, a cam for controlling the brake to provide maximum braking force when the supply of sheet or ribbon on the roll is a maximum and for reducing the braking force as the supply of sheet or ribbon on the roll is reduced, cam operating mechanism driven by the rotation of the supply roll to move the cam incrementally for each revolution of the supply roll, and a reset mechanism for resetting the cam back to its initial position following each feeding operation.
