feeders can be designed to orient a wide range of parts with one
The versatility and rapid changeover provided by these feeders make
ideal for flexible manufacturing where a number of traditional parts
might be required or where the volume of any one part might not justify
the use of a parts feeder. They are also well suited to mass
where a change in the parts being fed can be readily accommodated.

the required feed rate determine the size and type of feeder to be used
i.e. vibratory feeder with cascade bowl, vibratory feeder with an
track bowl, or a rotary orienting feeder. The part family and the
desired orientation determine the family of programmable feeder i.e.
I, Model II, or Model III.
family of programmable
feeders that are tooled without vision systems are members of the Model
I family. These units only use programmable or adjustable
tooling modules. Although much less sophisticated than the other
models of programmable feeders, these units are well suited to
simple parts such as headed parts and parts that have no end-to-end or
