The Conversion of a Processing Machine to the Soft-Touch Spring-Spool Demand-Drive System

Lawrence R. Witherow

The combination of the soft-touch tire and the spring-centered spool demand-drive system has provided the designer of film processing machines with a simple way of transporting film with excellent tension control and considerable flexibility in the way the processor can be used. This combination proved so simple and successful that it was soon not only being used for new machines but being utilized to convert existing machines with other film-transport systems. An example of such a conversion is described in detail as a guide to those who are contemplating the use of these innovations.
