ABSTRACT:
An arrangement for calendering bands of paper and like materials has one or more inelastic calendering rollers. Elastically deformable working rollers are associated with the calendering roller or rollers and are movable between operative positions in which they cooperate with the calendering roller or rollers to calender the bands and inoperative positions. Each of the rollers is rotated at a predetermined peripheral speed at which it calenders the bands. At least one of the working rollers has a drive capable of rotating it at a peripheral speed which is a small fraction of the predetermined peripheral speed. This working roller serves as a spare and is held in its inoperative position during a calendering operation while being rotated at a lower peripheral speed. When one of the working rollers in use becomes damaged or worn, the spare working roller is accelerated to the speed of the other rollers and is then moved to its operative position in order to assume the function of the damaged or worn working roller. The damaged or worn working roller is simultaneously moved to its inoperative position so that it may be repaired or replaced.
