Vorrichtung zum Erhitzen von plattenförmigen Teilen aus tiefziehfähigem Kunststoff

摘要

An apparatus is described for heating plastic plates (1) by means of contact heat and hot gasses, which are brought to the plastic plate (1) to be heated via supporting plates (2, 2'). In this case, two supporting plates (2, 2') can be moved in relation to each other perpendicularly to their common contact surface (3). Furthermore, gas-carrying lines (11) open out in the contact surface (3). …In order that the plastic plates (1) to be heated can be readily released from the heating plates (2, 2'), so as to avoid damage to the heating apparatus, the contact surface (3) of both supporting plates (2, 2') is in each case surrounded by a frame-shaped, closed outer border (4) without outlet openings of the gas-carrying lines (11). ……
