When you use the palte bending machine.In some cases, however, it is possible to find bending defects and more precisely the barrel defect.

You have the barrel defect when the pipe is closed at this ends, but it is more or less open in the middle. This defect is caused by the roll flexion under the bending strength


CAUSE 1: The plate is too thick in relation to the machine performance

SOLUTION 1: You cannot solve this problem, unless you use a machine with a higher performance


CAUSE 2: The plate is pinched between the two middle rolls with too much pressure

SOLUTION 2: Slightly lower the bottom roller to reduce the pinching strength
