摘　　要：It is desirable to get a uniform load distribution for the pressure rollers of the mangle.In thispaper,the load uniforming principle of the axially-staggered pressure rollers and the rules for theroller design have been analysed by the theory of bending of beams.The ratio of maximum tominimum value of the distributed load in the nip being taken as a useful index to describe the uni-formity of the load distribution,the performance of the so-called load-uniforming pressure rollerswith rubber covering,under various operation conditions,has been evaluated.As a result,it isproved that the load-uniforming pressure rollers with axially-staggered contact is a pratically use-ful means of uniformizing the load distribution,which ensures that the mangle will squeeze the ma-terial to be processed uniformly over its whole width under any technological load,and needs onlysome simple regulations.The conclusions obtained in this paper can easily be extended to the pressure rollers with anysupport conditions.It is desirable to get a uniform load distribution for the pressure rollers of the mangle.In this paper,the load uniforming principle of the axially-staggered pressure rollers and the rules for the roller design have been analysed by the theory of bending of beams.The ratio of maximum to minimum value of the distributed load in the nip being taken as a useful index to describe the uni- formity of the load distribution,the performance of the so-called load-uniforming pressure rollers with rubber covering,under various operation conditions,has been evaluated.As a result,it is proved that the load-uniforming pressure rollers with axially-staggered contact is a pratically use- ful means of uniformizing the load distribution,which ensures that the mangle will squeeze the ma- terial to be processed uniformly over its whole width under any technological load,and needs only some simple regulations.
