Abstract
PURPOSE:To reduce the size of a web winder by supporting a proximate roll through an air-cylinder thereby eliminating an independent press roll. CONSTITUTION:When the surface of a web roll 5 is pressed by means of a proximate roll, the gap between the web roll 5 and the proximate roll 20A is set to a minus value. Consequently, the proximate roll 20A presses against the surface of the web roll 5 continuously through function of an air-cylinder 40. When the proximate roll is used for its primary purpose, pneumatic pressure of the air-cylinder 40 is set to a maximum level and the gap between the surface of the web roll 5 and the proximate roll 20A is maintained at a constant level by means of an absolute encoder 64 and a reversible motor 60. Upon contact of the web roll 5 and the proximate roll 20A due to malfunction of the encoder 64 and the motor 60, the air-cylinder 40 functions as a safety device and protects the web roll 5 and the proximate roll 20A from damage.
