Definitions

  • ABSTRACT A platen press has an upper platen which is prestressed in compression, by tie bars which force the upper platen against cross pieces in a rigid condition, permitting the upper platen to be smaller in its physical thickness dimension, in order to minimize the length of the drive chains, and reduce the operating noise of the press.
  • FIG. 3 PRIOR ART FIG 2 FIG. 3
  • the present invention relates to a platen press and more particularly to such a press in which drive chains are employed to transport sheet material through the press.
  • the Prior Art Conventionally in platen presses a plurality of gripper bars are mounted on endless chains and are pulled by the chains through the press. A sheet of material is gripped by each of the gripper bars, and by this means is transported through the platen press.
  • the lower platen is typically positioned below the path of the sheet material and rises to press the sheet material against an upper platen when the sheet material has been correctly positioned therebetween.
  • Another object of the present invention is to provide a platen press structure in which the upper platen may be made relatively smaller.
  • a further object of the present invention is to provide a platen press structure which is less noisy than conventional presses.
  • a platen press having an upper platen mounted in fixed position above a horizontal reach of the drive chains adapted for transporting sheet material through the press, and rneans for prestressing said upper platen in a vertical direction.
  • FIG. 1 is a side elevation, partly in cross-section, of a conventional platen press
  • FIG. 2 is a side elevation of apparatus for prestressing the upper platen constructed in accordance with an illustrative embodiment of the present invention.
  • FIG. 3 is a side elevation of the operative portions of a press constructed in accordance with the present invention.
  • the upper platen l as shown in the press of FIG. 1 is a relatively large and bulky structure comprising, in addition to the horizontal lower surface 2, a plurality of upstanding ribs which are joined at their top ends by a top member. All of this structure is conventionally needed for strength and inertia, to withstand the large forcesarising from the upward movement of the lower platen 3.
  • FIG. 2 illustrates a side elevation of apparatus adapted to pre-stress the upper platen of a platen press, so as to reduce its bulk and size, without affecting its ability to withstand operating forces.
  • a lower support member 12 supports a cross piece 13 and the upper platen 14 rests on top of the cross piece vl3.
  • the crosspiece 13 is U-shaped, so that only the end portions of the cross-piece 13 bear upwardly on the upper platen 14.
  • the upper platen 14, the cross piece 13, and the lower support member 12 are all connected together by means of tie bars or clamps which clamp the assembly firmly together along the axes l5 and 16. Machine screws or bolts may conveniently be used to maintain all of the parts of FIG.
  • FIG. 3 illustrates a platen press incorporating the present invention therein.
  • the upper platen 14 is shown with its lower surface above the reach of the chains 9, with the cross piece 13 and the lower support member 12 mounted therebelow.
  • a separate cross piece 13 is provided for each side of the upper platen 14, so that its center portion is maintained unobscured.
  • the upper surface of the upper platen 14 is provided with a pair of grooves for receiving the chains 9, as they pass along their upper reach.
  • the gripper bars 4-8 may be located much closer together on the chains 9 than in the conventional arrangement.
  • a platen press having a support member, an upper platen, a pair of cross pieces, said cross pieces being placed on opposite sides of said upper platen between the upper platen and said support member, and means tightly urging said cross pieces against the upper platen to pre-stress the upper platen.
  • Apparatus according to claim 1 including a chain surrounding said upper platen, said chain being adapted to convey material to be processed into position relative to said press, said pre-stressing permitting said upper platen to be smaller in its physical dimensions and therefore allowing a shorter chain to surround said upper platen.
  • Apparatus according to claim 1 including a conveyor for conveying material to be processed to a position below said upper platen, said upper platen being adapted to engage the upper surface of said material during the processing of said material.
  • said urging means comprises a pair of tie bars for each of said cross pieces, each of said tie bars compressing a portion of said upper platen against one of said cross pieces.
  • tie bars comprise bolts received in aligned apertures in said upper platen, said cross pieces and said support member.
