  • the machine-supported are preferably working Cylinder / piston assemblies on the press plate is adjacent to the fixed press table.
  • the invention is based on the consideration that one, to the outside Press plate of the press plate arrangement connected synchronizing device sufficient to ensure proper vertical guidance ensure the press plate assembly if the press chambers of the press plate assembly opened in alternating cycles and be closed. Is that between the moving ones Press chamber formed press chamber closed, so form the interposed of the material to be pressed against each other clamped press plates a functional unit, the proper parallel alignment to the press table the synchronization device is ensured. Is it on the first press chamber adjoining the fixed press table, so forms under against the press table Interposition of the pressed material clamped a press plate Functional unit with the press table. That of the outside Press plate assigned synchronizing device guaranteed a parallel alignment of the outer press plate when Opening and closing the between the two press plates formed bale chamber.
  • the Synchronization device on gears that are spaced from each other stored on the outside of the outer press plate are rigidly coupled by waves and on vertical Unroll guide racks.
  • the gears are useful at the ends of two parallel ones, on the outside of the Press plate mounted pinion shafts, the Pinion shafts via bevel gear assemblies and a clutch shaft are interconnected.
  • the mechanical synchronizing device is dimensioned that uneven pressure distributions occurring during the pressing process can be compensated. Got it a foreign body in the bale chamber, there is a risk overloading and damage to the synchronizing device.
  • An emergency shutdown is therefore advisable if in spite of the synchronization device, an inclined position of the press plate during the stroke.
  • An emergency shutdown can be set up if the shaft bearings of the Synchronization device with a split plummer block housing are formed, with a lower half of the housing Plummer block housing is attached to the press plate and the upper half of the plummer block housing against a preloaded Spring arrangement vertically movable on the lower Half of the housing is supported. It turns out, e.g. B.
  • the synchronizing device also expediently has guide rollers on that at right angles to the gears are aligned and roll on flat guideways.
  • the invention teaches that Press frame has pillars on the long sides arranged and screwed to the press table or are welded, and that the machine-supported Cylinder / piston arrangements on the one hand on a pillar and on the other hand connected to the associated press plate are. This version results in a special compact design of the multi-daylight press.
  • the multi-chamber press shown in the figures is for Hot pressing of plate-shaped workpieces made of wood or wood-based material with glued foils, veneer layers and the like.
  • the basic structure of the Press include a press frame 1, one in the press frame 1 fixed press table 2, vertically movable Press plates 3, 3 ', 3' 'below and above the press table 2, cylinder / piston arrangements 4, 4 'for the adjustment movement of the press plates 3, 3 ', 3' 'and mechanical Synchronization devices 5 for the vertical guidance of the movable Press plates 3, 3 ', 3' '.
