Abstract
A high precision feed chain includes multiple support platforms that are each rigidly attached to master links in a drive chain. The master links are pivotally coupled together forming a single continuous drive chain capable of advancing in a longitudinal direction. The support platforms and the drive chain run along a channel in a guide assembly. The guide assembly allows the chain to advance in the longitudinal direction while at the same time maintaining the support platforms in a stable latitudinal and horizontal orientation.
