B&K® Precision Corrective Levelers

B&K® Precision Roller Levelers utilize a series of relatively small closely spaced leveler rolls that incorporate roller back-ups to prevent deflection. This arrangement allows the material to be worked beyond the yield point to remove trapped material stresses. The result is material that is more stable so that flat sheets remain flat.

The back-ups are multiple sets of narrow rollers spaced evenly across the face of the work roll. These back-up rolls are adjustable in order to control the deflection of the work rolls and thus how and where the material is worked. This setup, utilized by the 4-High configuration is suited for most material applications.

Over time, the backup rollers may produce a mark on the work rolls, which can be transferred to the surface of the material. To prevent this, another set of full width rolls is placed between the upper work rolls and the upper back-up flights in the 5-High and 6-High configurations. These intermediate roll(s) help to distribute the pressure of the back-up rollers across the surface of the work roll.
