Definitions

  • a preferred embodiment of the invention comprises the features that the tray is divisi- ble because of the fact that it comprises lamellar means of the above-described type which are dismountably arranged on one another.
  • the lowest lamellar means is preferably detach- ably arranged on a bottom plate in the press chamber.
  • a diaphragm support is preferably arranged above the uppermost lamellar means, and a press plate is, in its turn, arranged above the diaphragm support .
  • the holes in the lamellar means thus together form a space which is defined by the inner wall of the internal lamellar means, the bottom plate and a diaphragm which is placed in the diaphragm support.
  • lamellar means are separate units which, by degrees, together are to form a tray, manufacture of them can be accelerated considerably.
  • various lamellar means blanks can be machined in the respective stations at the same time.
  • a first lamellar means blank can be machined in a certain station and when this lamellar means blank has been moved on to a subsequent station for further machining, a second lamellar means blank can be machined at the same time in said certain station.
  • This parallel performing of different manufacturing steps thus turns out to be very beneficial . It is also distinctly easier to move a relatively thin lamellar means in comparison with a large traditional tray.
  • some stations can machine several la- mellar means blanks simultaneously.
  • the distance means 38 are made of a relatively rigid material and their inner diameter is larger than that of the coupling means 36 at the same time as their external meas- ures are essentially larger than the apertures arranged in the lamellar means 12.
  • stop devices 40 At the two external ends of the coupling means 36, outside the respective external lamellar means 12 which are included in the press body, there are stop devices 40 of which at least one has a fixing and clamping mechanism which is complementary to the coupling means 36.
  • the attaching and stressing mechanism can comprise a washer and a nut, the washer having external measures which are essentially larger than the coupling apertures of the external lamellar means.
  • the four coupling means 36 are thus tightened to a predetermined prestress condition. This eliminates
