Roller Crowning Services

Not Just for Nip Rollers | Crowns Can Improve Material Handling for Many Rollers

Menges Roller provides industrial roller crowning services, which are primarily utilized by nip rollers and long rollers to prevent damage from deflection; this is an important rubber roller finishing service.

Heavy Load Deflection Illustration

This illustrates the forces deflection on a roller; and deflection is amplified with roller length and rotation speed. A Menges Engineer can assist in calculating the proper crown for your application.

This picture shows a large industrial roller being crowned by Menges Roller Company, which specializes in manufacturing and servicing rubber rollers and chill rollers at their facility in Wauconda Illinois.

23 Foot Roller with Crown

This roller's length (28+ ft.) illustrates the concept of deflection. We built-in a .059" parabolic crown to compensate for the roller's deflection coefficient.

This picture shows the procedure for applying a parabolic crown to an industrial roller at the Menges Roller Company facility, which offers several services for silicone rollers and rubber rollers.

Shape of Parabolic Crown

The technical name is the Cosine Curve. This parabolic shape will compensate for deflection in nip rolls or long rolls.

Crowning services provided by Menges Roller Company, a high-volume industrial roller manufacturer, include reverse parabolic crowns as an option on rubber rollers and silicone rollers, as indicated in this technical illustration.

Reverse Parabolic Crown

Reverse parabolic crowns (concaved), prevent lateral runout and 'steer' the web, keeping it in on a designated track.

Menges Proof-Nip Impression Paper

Crowning services provided by Menges Roller often involved nipping systems, and this illustration shows how to measure nip system pressure using Menges Roller’s Proof-Nip Impression Paper.

To test your nip pressure and crown profiles, use Menges Proof-Nip Impression Paper.
Inserted directly into the nip, it clearly shows areas of high pressure, low pressure and no contact.

At Menges Roller Company, computers are used to form precision crowns on rubber nip rollers, and this picture shows how technicians utilize this CNC crowning equipment.

Computer Controlled Crowning Machine

Computer controlled crown-forming machines ensure the accuracy and exact dimensions of each crown, which are usually just a few hundredths or thousandths of an inch.

Large industrial rollers covered with rubber, silicone or urethane may by receive a parabolic crown or a reverse-parabolic crown, both of which are offered by Menges Roller Company, as seen here.

Roller Crowning Services On A Long Roller

Our technician is forming a .011" crown on an EPDM-covered paper industry roll. Menges can crown rollers up to 10 meters long. Few roller companies have this capacity.

Generally speaking, a crown helps compensate for the effects of 'deflection,' which is a slight bend or arc in the roller due to extreme pressure and the ends (as with nip systems) or because the roller is very long and dips slightly in the middle.

Parabolic crowns are most often applied to nip rollers, but crowns may be recommended for many roller types. Crowns and reverse crowns are used to slightly stretch the web, reduce wrinkles, or even 'steer' the substrate and prevent drift.

Menges Roller applies crowns to both rubber-covered rollers and hardshell rollers - but our engineers may also help you by diagnosing your nip system and specifying the proper dimensions for precision crowns.
