"Vintage Machinery" entry for Warner & Swasey Co.

An improved knitting machine includes an encoder which provides signals which vary with variations in the relative position of a needle cylinder and associated feeders. The encoder includes code tracks for providing binary coded needle count signals, feeder count signals, and revolution count signals. A control system receives these binary coded signals and effects the knitting of a selected one of a plurality of patterns. A pattern selector switch is operable to vary the selected pattern.
