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.

Abstract: Disclosed is a switch for a suspended track transport apparatus, particularly of the building-block type and especially for interior use in the apparel industry. The switch comprises a support structure which includes two support tubes connected together at an angle to each other and a cross-stiffening element connected between the two support tubes. Stationary track sections are supported by the support tubes. Movable track sections are movably supported by pivot bearings and are coupled to each other by a lever apparatus. A switch setting device determines the switch position. The lever apparatus and the pivot bearings are accommodated within a dead space having sides extending along the support tubes and the cross-stiffening element of a height not exceeding the distance from fixed track sections to the support tubes. The lever apparatus is engaged in the vicinity of the movable track sections and is held at one end in the pivot bearing.
