Thin strip is also less resistant to buckling. Mild shape problems can be corrected by stretch leveling the strip in tension or by bend flexing the strip in a rollerleveller. Mill spring is a defect in which the rolled strip is thicker than the required thickness since the rolls get deflected by high rolling forces.

Backing up the roll former can allow you to look for pressure marks, misalignment problems in a radius, or roll stops that are being hit too hard. Using a straight edge on the back side of the roll form tooling will indicate machine face alignment problems and will show if the top roll form tooling is parallel with the bottom roll form tooling.

The biggest rollers do not necessarily give the best throughput, especially when budget is factored in. If the goal is to run creams or lotions at a decentsize volume, a threeroll mill of 50 mm diameter would be sufficient. For media, such as pastes, which may require a stronger machine, a 65 mm diameter threeroll mill would be suitable.

To minimize the roll diameter a fourhigh or cluster mill is used. A small roll diameter is advantageous because less roll is in contact with the material, which results in a lower force and power requirement. The problem with a small roll is a reduction of stiffness, which is overcome using backup rolls.
