This article commences with a description of the four basic types of feeding arrangements, namely, hand feeding, hitch feeds, roll feeds, and slide feeds. Air feeds offer the utility of use with a wide variety of presses and machines. The article discusses the mounting and actuation of the air feeds, which allows automatic feeding in machinery that is not normally adaptable to the use of standard feeds. Automatic press feeds are used to improve production and provide uniform, accurate progressions. The article describes the accuracy control techniques for the automatic press feeds and concludes with information on air circuits for the air feeds.
