OVALNESS ERROR
This is the condition where the ends of the final form run into each other on one side. This
means that material diameter is not fixed and excessively wide in relation to the axes.
CAUSE = it may be caused by the dimensions of the plate to be bent
REMEDY = lower ROLL is lowered down to the lowest position and some rotation settings are
performed for the tube.
Lower ROLL is kept in the lowest position during this operation. Otherwise, welding or other
factors may cause serious damage to the machine.
BENDING ERROR
This error is caused by the fact that the force of rolls are very high. Plate comes out of the
machine and irreparably damaged.
Compression pressure of the rolls are reduced using the ROLL compression pressure setting
device.
WRONG AXIS ERROR
This condition occurs when evenness of rolls is wrong and when plates with irregular
thickness are used; alignments and evenness shall be checked in this condition. There is no
solution as this is caused by the material itself.
