Where do the flats at the beginning edge and the trailing edge of the rolled come from? Is there anyway of eliminating them? |

When I read in the specifications of manufacturers of plate bending rolls that the “pre-bending thickness capacity” is a certain thickness, I find next to it a “Rolling only thickness capacity” which is usually higher in value. Explain what this means. |

What role does cambering of the rolls play in plate rolling and why is it necessary? |

I would like the new plate roll I purchase to roll without defects through the largest thickness range…how do I do that? |

Searching different plate roll manufacturers’ sites, we noticed some use the orbital bending roll approach to the top roll and others use the rectilinear slide construction. Each claims the plate bending machines they sell offer the superior design. Can you give me your perspective on the subject? |

We noticed the same capacity machine from two manufacturers having different net weight and different HP motors for their hydraulic power source? Why? Does heavier and higher horse power mean a better 3 roll plate rolling machine? |

Why are most plate roll and plate bending machine manufacturers giving their specifications in a format “Rolling 36,000 psi/ 250 N/mm² Yield Strength Material rolled to 3X or 5X top roll Ø” or “Rolling A36 steel to 3X or 5X top roll Ø” and you are advertising “Rolling 50,000 psi/ 350 N/mm² Yield strength Material rolled to 1.4X top roll Ø”? |

We purchased an Omega 100. In the specifications it says the section roll will roll 4”x4”x1/2” leg out (100mmx100mmx12mm)…We have an angle 3”x5”x3/8” = 75mmx130mmx10mm and we want the 5” (130mm) leg to be leg out. Can the section bending machines do this and how do we calculate such cases in the future? |
