Machine for processing a continuous web or sheets

In a machine having a pair of cylinders for processing a continuous web or sheets passing between the nip thereof, the cylinders having shafts journalled at opposite ends in a frame of the machine, the size of the nip between said cylinders being adjustable, a first pair of auxiliary casings supporting first bearings on the ends of said shafts and lying in a first plane, a second pair of auxiliary casings adjacent said first casings and supporting second bearings on the ends of said shafts and lying in a second plane, said planes lying parallel to each other and perpendicular to said shafts, said pairs being mounted on said frame for relative adjustment of said casings of each pair to one another and to said frame along said planes, at least one first pressure medium cylinder means acting between said frame and at least one of said casings of said first pair, for effecting said relative adjustment thereof, at least one second pressure medium cylinder means acting between said frame and at least one of said casings of said second pair for effecting said relative adjustment independently of said relative adjustment of said first pair, whereby the size of the nip between the cylinders is adjustable and force flows between said shafts and said frame are caused to travel along each of said planes.
