Must be of a permanent nature, able to withstand scrubbing with trichloroethane cleaning agents. 2. Must withstand scrubbing across glass while intermittently skidding paper across a glass surface. 3. Must in addition to the above, remain in sharp enough contrast to the white surface of the belt, to permit legible copying.

Marking Method

This method is an improved marking method for marking a belt in a business machine, which meets the following requirements:
1. Must be of a permanent nature, able to withstand

scrubbing with trichloroethane cleaning agents.
2. Must withstand scrubbing across glass while

intermittently skidding paper across a glass surface.
3. Must in addition to the above, remain in sharp enough

contrast to the white surface of the belt, to permit

legible copying.

In practicing the method, the belt, which has a white surface coat, is branded with heated metal type. The type is heated and then pressed into the outer surface of the belt. This melts into the outer surface leaving a branded character and exposes the belt carcass.

After branding, a black dye is applied to the branded area by the following two steps:
1. The area is first coated with a black grease pencil.
2. The excess is then washed away with a solvent which

dissolves the black grease, allowing the exposed carcass

to accept the black dye.
