Roller Crowning Services
Not Just for Nip Rollers | Crowns Can Improve Material Handling for Many Rollers
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.
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.
Our Roller Crowning Services:
- Available on New Rollers & Re-Cover Projects
- For Rubber-Covered Rollers & Hardshell Rollers
- Generally Hundredths or Thousandths of an Inch
- Formed using Computer-Controlled Machines
- Menges Engineers Determine Proper Crown Specs and Calculate Optimal Cosine Curve for Each Situation
- Menges Proof-Nip Impression Paper is Available to Measure Your Nip System Pressure & Analyze Crown Problems
- Order by Calling 847-487-8877
Shape of Parabolic Crown
The technical name is the Cosine Curve. This parabolic shape will compensate for deflection in nip rolls or long rolls.
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
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.
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.
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.
