Definitions

  • a further object of my invention is to provide heating platen press wherein the stationary and displaceable press structures, the individual crossbeams, the press platens, the bridge members and the ribs can be sub jected to varying thermal effects through varied controllable heating and cooling by means of a plurality of circulatory loops, in order thereby to be able to correct deformations caused by thermal stresses and in order to maintain a compression surface that deviates from a planar surface.
  • the fluid medium is circulated in a sinuous path through one or more circulatory loops within the stationary base and displaceable press structures, the heat distribution beginning by the removal of heat in bores fonned in the bridge members and the ribs adjacent the press platens, is then passed through connecting lines repeatedly to other bores formed in the bridge members and the ribs located opposite the first-mentioned bores and successively more distant from the press platens, until the medium discharges from bores located in the vicinity of the neutral axis of the press structures and is conducted to circulating pump.
  • FIG. 1 is a side elevational view, partly in section of the heating platen press according to the invention.
  • the press platens 2 which are relatively thin as compared to the thickness of the stationary and displaceable press structures 1 and 2, act flexibly and can freely expand because they are loosely mounted and can assume the shape of the structures 1 and 2 during the compression operation. Furthermore, the individual bores l0, 11, 31 and 33 of the bridge members and the ribs 5, l9 and 20, respectively, can be discriminately supplied with heating or cooling media so that the individual bridge members 4 and ribs 5, 19 and 20 mutually assume a varying shape (deformation) and thereby correct the negative or tolerances of the material being compressed.
  • FIG. 3 there is shown uniform heat distribution into the stationary and displaceable press structures 1 and 2 wherein fluid medium is driven by the circulatory pumps 35 in a meandering or substantially helical path about the neutral plane A-B.
  • each of said structures has a neutral plane, said circulatory loop extending sinuously about said neutral plane, and said fluid circulation passages being made up of bores formed in said bridge members and said rib members, and including connecting lines interconnecting said bores.
