Ultrasonic Welding Method for Photoconductor Belts

A length of flexible xerographic photoconductor (PC) web is formed into an endless web by subjecting the web ends to ultrasonic energy, with the ultrasonic horn being placed against a metal shim which is intermediate between the horn and the PC surface.

The two ends of web 10 are overlapped with PC side 11 facing shim 14 which in turn contacts ultrasonic welding head 13. Ultrasonic horn tip 13 is about
0.5 inch in diameter.

Shim 14 can be of any suitable metal about 0.001-0.005 inch thick and with a width relative to the 0.25 inch dimension of the head of about 0.8-0.9 inch. The edges of shim 14 facing the PC have rounded radii of about 0.060 inch.

Substrate 24 is a polyester film such as Mylar (E.I. du Pont de Nemours & Co.) about 0.003 inch thick and PC layer 11 is about 0.001 inch thick.

Horn 13 is run against shim 14 with a force of about 5-10 pounds at a rate of about 1-1.5 inches per second.

The resulting lap-joint is smooth on the upper PC side of the belt since PC layer 11 below horn 13 flows from under the upper substrate layer, fills in step 16, and is calendered to a smooth surface by shim 14.
