Abstract
The disclosure relates to an improved die transfer system for a press having bolster with conventional inverted T-slots therein. The system comprises a pair of elongated, parallel vertically movable rails. 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 T-slots 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. The rails have laterally extending flanges that are engageable with complementary shoulders of the T-slots to limit upward movement of the rails and preclude bowing of the rails.
