ABSTRACT:
A safety guard for the nip of two neighboring rolls in a calender has an elongated support which is located in front of the nip and has two elongated strip-shaped barriers each adjacent but spaced apart from the peripheral surface of one of the rolls. The support is mounted on the bearings for one of the rolls for pivotal movement about an axis which is parallel to the nip and carries cams which are biased against rollers on the bearings for the other roll by one or more reversible motors. If the bearings for one of the rolls are moved relative to the bearings for the other roll, the cams move along the respective rolls and/or vice versa, whereby the orientation of the support and of the barriers thereon is changed so that the width of the clearances between the barriers and the peripheral surfaces of the adjacent rolls does not exceed a maximum permissible value such as would enable a careless operator to introduce a finger into the nip.
