Abstract

413,174. Moulding electric hot-plates. SIEMENS - SCHUCKERTWERKE AKT. - GES., Siemensstadt, Berlin. Nov. 10, 1933, No. 31378. Convention date, March 11. [Class 87 (ii).] In the process of moulding an electric hotplate in which a heating resistance 16 is embedded between upper and lower layers of plastic insulating-material 15 by pressure, the platen of the press is subdivided into a number of yielding plungers 13 which are actuated from the main stamp head 11 through the medium of a rubber cushion 12 or through a cavity filled with steel balls or other pressure-equalizing medium. By this means, the whole surface of the hot-plate is subjected to equal pressure notwithstanding variation in thickness of the layer of material. The work-contacting faces of the plungers may be made concave to facilitate release of the material on the upstroke, and may also be grooved to permit escape of air.
