Abstract
A process of forming and shaping a preheated workpiece made of honeycomb core material using a press including complementary male and female dies. The first step of the process is providing a carrier sheet for supporting the workpiece. The carrier sheet is suspended over the female die by two shafts supported by support towers. The next step is loading the preheated workpiece onto the carrier sheet. The next step is applying rotational torque to each of the two shafts whereby the carrier sheet is wrapped around the said shafts thereby applying tension to the carrier sheet and pulling the shafts toward each other and into pressing contact with the sides of the workpiece while said carrier sheet means supports the bottom surface of said workpiece. The next step is closing the male die and the female die against the workpiece while maintaining the shafts in pressing contact with the sides of the workpiece and while the carrier sheet supports the bottom surface of the workpiece, whereby the workpiece is formed and shaped by the complementary male and female dies into a formed workpiece of the desired shape. The final step is opening the male and female dies and removing the formed work…
