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.

Abstract: A device for heating plastic plates using contact heat and hot gases which are supplied to the plastic plate to be heated by carrier plates is provided. Therein, two carrier plates are movable relative to each other vertically with respect to their common contact surface. Gas distribution conduits also open in the contact surface. In order that the plastic plates which are to be heated can be removed properly from the carrier plates, so that damage to the heating device is avoided, each contact surface of both carrier plates is surrounded by a frame-like, closed outer edge without mouth openings for the gas distributions conduits.
