Abstract:
An apparatus for winding a web of paper material into a roll, the apparatus comprising:a rotatably mounted reel spool onto which the web of paper material is to be wound to form a roll of increasing diameter;a reel drum rotatably mounted adjacent to the reel spool;a carriage supporting one of the reel drum and the reel spool so as to be movable relative to the other and positioning said one of the reel drum and the reel spool adjacent to the other such that a nip is formed therebetween;an actuator connected to the carriage and operable for moving the carriage to urge the reel drum and the reel spool relatively toward each other so as to cause the reel drum to indent the roll of paper radially inward locally at the nip;a sensor unit which provides a signal indicative of the radial indentation of the reel drum into the roll of paper; anda controller connected to the sensor unit and to the actuator and operable for controlling the actuator to move the carriage so as to maintain within predetermined limits the amount of radially inward indentation of the reel drum into the paper roll at the nip.
