ABSTRACT:
A moistening arrangement for moistening the flap of an envelope includes a moistening device for moistening the flap of the envelope, a source of first signals that are a function of the width of the flap, a motor coupled to provide relative movement between the nozzle and the flap, and a control arrangement responsive to the first signals for controlling the motor to vary the relative positions of the flap and nozzle in a direction for moistening the flap at determined positions thereof. The control arrangement comprises an arrangement responsive to the signals for determining the rate of change of the first signals, an arrangement responsive to the rate of change below a determined rate of change for controlling the motor to move in a servo mode, and an arrangement responsive to the rate of change above the determined rate of change for controlling the motor to move in a torque mode.
