International ClassB30B 003/04Foreign Application Priority Data1987-04-23 DEAbstractSupport of a nip relieving device to compensate for overhanging weights at an elevationally displaceable bearing part of an intermediate roll of the calender is effected relative to the stand of the calender by an elevationally displaceable support member. This support member is displaceable by a threaded spindle which is rotatable with a motor and gearing and supported by the stand, to which threaded spindle the support member is individually engageable. The support member is thus individually displaceable to the related bearing part, according to the elevational position thereof, into a desired relative position. According to a preferred embodiment, the components of the nip relieving device are arranged in a bearing sleeve enclosing the threaded spindle and the support member is formed by a nut which is elevationally displaceable by rotation of the threaded spindle. | |
