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. |

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 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 specifications. |
