ABSTRACT:
An apparatus for winding small rolls of paper from large rolls includes a counter to measure the length of the web being wound, a presser to sense and control the outer diameter of the small rolls, an encoder to detect and control the diameter of the small roll as it approaches the pre-determined desired diameter thereof, and an electronic logic control connected to the counter, the presser and the encoder whereby to ensure that the weight of paper and the outer diameter of the small rolls will always be within the predetermined limits. The apparatus may also include a device to record the weight of the small roll and sensors to automatically adjust the length of the web and also the roll diameter as the small roll is being formed. The sensors may also include fine and coarse tuners to adjust more precisely the movement of the web onto the small roll within relatively narrow tolerances.
