    Om rubber rolls manufactures rollers for paper industry based on roller operating parameters. Roll technology involves the manufacture, covering & servicing of large metal rolls (Up to 9 mtr. Long, 1.8 MM in Dia & 60 Tons WT). Over which clothing (Wire & Felt) products & between which paper web moves from wet slurry to finished paper. Many rolls are used in each paper making machine. Om rubber rolls covered products provide a surface that gives mechanical properties necessary to process the paper sheet that delivers the desired paper qualities by the producer. Our roll qualities are based on parameters like application, chemistry, speed, temperature, pressure, Roll geometry, deflection, balance & coefficient of friction. Our products include:

    • Rubber Covering
    • Re-Grinds
    • New Core Design & Fabrication
    • Core Repair
    • Ultra sonic test & Balancing machine
    • Crowning
    • Grooving
    • Engineering Services
    • Extensive Field Support

    Om rubber rolls has developed a Premium range of compound Excel, Ultimex, Super Rock & Ultra Super Rockwhich has superior release characteristics and dimenional stability. Resistance to chemical & steam environment. Thermal stability & Operates at high pressure. The compound is Designed to withstand Nip Load upto 500 kg per Linear cm. The below chart is a glimpse of the newly developed superior compound.

    COVERING MATERIAL NAME HARDNESS ROLLER NAME CHARACTERISTICS
    SHORE A P&J

Drilling provides longer nip dwell time. Premium bonding system for long service. Homogenious composition provides excellent moisture profile.
    EXCEL 500
    ULTRA FLEX COATING 88-92 25 TO 30 Film Press Roll Superior wear resistance at high speed, minimal after hardening for stable process, excellent runnability & economical solution coating.
    CRYSTAL COATING 88-90 25 TO 30 Film Press Roll Good wear & wad resistance, provides long run, resistance to sizing chemicals, excellent water resistance (hydrophobic). Very good runnability.
    CRYSTAL COATING 68-72 75 TO 80 Backing Roll
    SUPER DIAMOND COATING 84-85 _ Top Press Roll Premium compound with superior release characteristics and dimensional stability. Resistance to chemical & steam environment. Thermal stability & Operates at high PSI.
    SUPER ROCK COATING 84-86 _ Top Press Roll Excellent weart resistance, easy sheet release properties and good doctorability.
    ULTRA SUPER ROCK COATING 85-87 _ Centre Press Roll Hard rubber coating which provides stable runnability & superior sheet properties. Effective doctoring at such demanding positions as bi-nip rolls. Superior chemical resistance & maintains hardness at high temperature.

    Advantages :

    • Increased sheet dewatering
    • Better quality paper because of:
      • Smoother paper finish
      • Improved paper levelness
      • Better porosity features
      • Reduced linting
      • Improved printability
      • Reduced two sidedness
    • Improved cross-machine moisture profile
    • Longer felt life
    • Suitable for virtually all types of press sections
    • Cost-effective due to its improved runnability, energy savings and increased production.
    • We have Voith making drilling machine capable to drill Suctions roller dri-press & dri-press (B.D.R) efficient of drilling one roller within 12 Hours.


    To make maximum use of your Dri-Press.
    Om rubber rolls Rubber introduces the Dri-Press to provide more efficient water removal than other venting techniques.

    BALANCING & ULTRASOUND MACHINE

    We have the facility of both balancing the Dynamic & static. Many ultra modern tests like Ultra Sound, Radiography for these minor invisible cracks are conducted before each core is passed on to avoid big problems at a later stage.

    The C.I. hub, fabricated Steel hub are bored and machine shaft are Shrunk, Fitted into the hubs with precision. The Hubs are shrunk & power pressed into the pipe. The Spindles are machined & dynamically balanced.
