Abstract
The disclosure relates to a die transfer system for a press having a bolster for the support of a die. The system comprises a pair of elongated, parallel upwardly opening cavities having horizontally extending vertically movable rails therein. A plurality of rollers are supported by each rail so as to be movable vertically therewith. An air bag extends longitudinally of each of said cavities under said rails and is engageable with the bottom thereof. Inflation of the air bags effects elevation of the rails and rollers into engagement with the bottom of the die and elevation of the die relative to the press bolster.
