FIGS. 2 and 3 illustrate in detail the mounting and the design of the table 15 which in relation to the planes 17 or 18, which run perpendicularly to the picture planes, is constructed essentially symmetrically. The table 15 has a central table part 19 and two table parts 21 which adjoin directly end faces of the central table part 19, which lie opposite one another in the longitudinal direction of the table 15, and which are pivotable about axes 20. The central table part 19 is in each case, adjacent to the table parts 21 in the area of its support surface, that is to say on top, provided with a recess 22, and the respective table part 21 is likewise provided with a recess 23 on the top and adjacent to the central table part 19. In the transition from the central table part 19 to the recess 22, the respective recess has a bridge segment 25 which is pivotable about an axis 24. The thickness of the table parts 21 and of the bridge segments 25 as well as the dimensions of the recesses 22 and 23 are calculated in such a manner that, with table parts 21 pivoted in and thus bridge segments 25 also pivoted in, the surface of the central table part 19 forms a plane with the upper surfaces of the table parts 21 and bridge segments 25. When the table parts 21 are folded up, the bridge segments 25 slide with their free ends 26 in the recesses 23 until, when the maximum folded out position of the table parts 21, which is pivoted out by an angle of approximately 55°, is reached, they come to lie adjacent to the undercut 27, which forms the recess 23, in the respective table part 21. The illustration of FIG. 2 explains that in the folded up position of the table parts 21 and of the bridge segments 25, an almost uniformly arched curve is determined by these and the central table part 19, in which connection it is of course possible to provide further bridge segments so that, when the table parts 21 are extended, the support contour of the table approximates a constant curve shape.
The breaking up of the part stack 5 can already take place in a position of the table 15 above the remaining stack 6, which is illustrated in FIG. 7. The part stack 5, which is resting on the table 15, at first forms a closed block, that is to say the individual sheets 48 cannot be displaced easily over one another, which is a prerequisite for an accurate alignment at the edges of the part stack 5 in the subsequent vibrating table 4. Therefore, after the stack 5 has been placed on the table 15, the pneumatic cylinders 30 are acted upon, which brings about a folding up of the table parts 21 and thus also of the bridge segments 25 into the position also shown in FIG. 2. In this position, as can be seen from the illustration in FIG. 7, the sheet plies, going from the neutral plane 17 towards the edges 49, are displaced to an increasing extent, so that in the area of displacement the block shape is already done away with. When the table parts 21 and bridge segments 25 are folded up, the two pressure rollers 40 are lowered onto the part stack 5 in the area of the two edges 49 by means of action upon the pneumatic cylinders 39. During this, the extended relieving hooks 42 engage behind the holding pins 43; by means of retraction of the relieving hooks 42, the pressure force of the pressure rollers 40 on the part stack can be adjusted to a desired amount, with which the part stack 5 is clamped in its edge areas between the pressure rollers 40 and the table parts 21. If the table parts 21 and thus the bridge segments 25 are then pivoted back by means of action upon the pneumatic cylinders 39, with the simultaneous follow-up of the pressure rollers 40, this brings about a stretching, which increases from the lower to the upper sheet plies, of the individual sheets 48 which thus separate from one another. Additionally, at this moment, by means of a large number of air nozzles 50 (FIG. 3) which are arranged at the side on the table 15, air can be blown between the individual sheets 48. Upon the further lowering of the table parts 21 and of the bridge segments 25 with simultaneous follow-up of the pressure rollers 40, when the upper sheet plies are drawn completely tight, the set braking moment of the pressure rollers 40 is exceeded, so that these roll off outwards on the uppermost sheet 48. As soon as the table parts 21 and the bridge segments 25 are completely folded in, the relieving hooks 42 are extended, whereupon they come out of engagement with the holding pins 43, the bearers 37 can subsequently be pivoted up by means of the pneumatic cylinders 39, so that the part stack 5 could now be advanced to the vibrating station 3. In general, however, the breaking-up process is repeated again, that is to say the table parts 21 are extended again, the pressure roller 40 lowered again, in certain circumstances also after prior rotation of the part stack 5 on the table 15 by 90°.
