drive components - typically a variable speed gearbox, operator
adjustment levers and perhaps a mechanical bag registration system are removed. They are replaced by the single
motor/gearbox assembly with its integrated encoder.
At
the rear of the cabinet you can see the assembly simply mounted to the
floor of the machine and driving the input shafts of three film
transport rollers as
well as the output conveyor on the far left. This image represents
perhaps the most complex type of machine, many machines have a simple
single or perhaps two shafts.
