Abstract

This invention relates to a method for making elastomeric belts, particularly grooved belts suitable for use in document handling devices. Frequently, grooves are needed on elastomeric belts, such as document handling belts. If such grooves are placed on the belts by hot embossing methods, the crystallinity and the strength of the belt material may be compromised. To make the grooves by a grinding process, or a casting process, would be relatively expensive.

This invention relates to a method for making elastomeric belts, particularly grooved belts suitable for use in document handling devices.

Frequently, grooves are needed on elastomeric belts, such as document handling belts. If such grooves are placed on the belts by hot embossing methods, the crystallinity and the strength of the belt material may be compromised. To make the grooves by a grinding process, or a casting process, would be relatively expensive.

The present invention proposes to make such grooved belts by cold embossing process. The cold embossing process does not adversely affect the crystallinity and the strength of the polyester belt. Flex fatigue life of the belt will remain high. The process is also very economical. Holes on the belt, if desired, may be formed on the belt by the punch and die method. Biaxially oriented polyester films available under the tradenames Mylar, Melenix and Celenar are suitable materials for forming such grooved belts by the method of the present invention. Such grooved belts have use in high performance recirculating document handlers in copying machines.
