Abstract
A tunnel finisher includes pneumatic rollers for defining an entrance and an exit for a pneumatic treatment chamber. The tunnel finisher is designed to facilitate the replacement of the envelope of pneumatic rollers. The shaft of the pneumatic roller consists of an upper section fixedly mounted in the tunnel finisher housing, and a one-piece lower section carrying roller-supporting discs, with its upper end releasably coupled to the upper section, and its lower end tiltably supported on a tilt bearing. The pneumatic rollers may thus be dismounted for simple and rapid replacement of the roller envelope, so that down-times of the tunnel finisher may be considerably reduced.
