Abstract
An arrangement for bending of a roll in a calender roll machine, to produce a crown in the roll, while minimizing any increased or decreased load on the bearing thereduring. The roll bending arrangement includes a sleeve assembly on each end thereof, which are each given a couple. The roll bending apparatus producing each couple is secured to the foundation or the frame of the machine so as to minimize any additional load on the roll bearings which carry the nip pressure.
Claims2
A roll bending apparatus for a calender roll machine comprising:
- a roll journaled in bearings pivotable in frames to accommodate bending of the roll, means acting on at least one end of the roll for inducing a couple to bend the roll carried by the bearings, the couple inducing means comprising a pair of pressurizable piston and cylinder units each pivotally secured at one end to the frame and pivotally secured at the other end to a bushing on said roll end, the units being adapted to apply oppositely directed forces to effect the couple on the roll without adding any appreciable load to said bearings.
