Abstract

A method is provided for heating and transferring a substantially flat workpiece made of a deep drawable plastic material including the steps of enclosing at least a substantial portion of the workpiece between first and second opposing carrier plates such that a gas-tight seal may be formed by one of the carrier plates about the substantial portion of the workpiece and supplying hot gases through a gas distribution conduit associated with the first carrier plate while withdrawing hot gases through a gas distribution conduit associated with the second carrier plate such that the workpiece is heated and transferred to the second carrier plate. The workpiece is then transferred to a third carrier plate or a deep-drawing device.
