Steps in Covering a Roller

1.

When received the journals or shafts are checked for wear and damage. We will contact you immediately with a quote to repair before proceeding any further with your order.  

2.

The roller is then mounted into a lathe and the old rubber or urethane is then stripped off of the core. In some instances we will burn the material off the core in an industrial oven.  

3.

The roller core is then cleaned to the bear metal with a tube polisher and prepared to receive the appropriate bonding adhesive. We also make new metal cores to your specifications  

4.

A primer is first applied.  

5.

Then a top coat of bonding agent is applied over the primer.  

6.

Uncured rubber in calendared form is wrapped around the core or in some instances we will mold the rubber to the core using a roll mold. With urethane the material is either molded in a press or cast and cured in an industrial oven. Typically, we overbuild the roller larger than the required finished diameter.  

7.

With calendared rubber the roller with uncured rubber is then wrapped with a wet nylon tape holding the rubber tightly to the bonding agent to the core. With molded rubber or urethane the curing occurs in the press or the oven.  

8.

A roller coated with calendared rubber is placed in an autoclave to cure the rubber, activating the bonding agent and bonding the rubber to the core. For rubber to cure, it requires both heat and pressure.  

9.

Once the rubber is cured and bonded to the core, it is then mounted into a grinding lathe. The roller is then ended to the proper length and ground to the proper finish od specification.
