Abstract
System for producing rolls of air-filled cushioning material which includes a machine for inflating and sealing a preconfigured film material to form a continuous sheet of air-filled cushioning material, and a winder having a spindle for receiving the inflated cushioning material from the machine, a drive motor for rotating the spindle to wind the inflated cushioning material into a roll on the spindle, and means for controlling the motor in accordance with the diameter of the roll to maintain substantially uniform tension in the material as the material is wound into the roll. In one disclosed embodiment, the diameter of the roll is monitored by a feeler arm, and in another it is determined from the rate at which the spindle is rotating and the rate at which the material is wound onto the roll.
