the continuous press according to the invention from Figures 1 and 2 in plan view.

The continuous press 1 according to the invention from FIG this embodiment of four arranged in series Work stations, a heating press 2 and a cooling press 3, continue from a right next to the heating press 2 arranged loading station 4 and one to the left of the Unloading station 5 arranged in the cooling press 3.

In this exemplary embodiment, the loading station 4 consists of two superimposed conveyor floors 6.7, each about a pivot axis 8.9 in the directions of arrow 12 Fig.1 are pivotally mounted.

The pivot axes 8.9 of the conveyor floors 6.7 are in this Embodiment, as can be seen in Fig.1a, in the Centers of the pulleys 13, 14 each to the Funding days 6,7 belonging conveyor belt 10,11 placed on the side of the loading station 4 are attached to the Connect heating press 2.

A swiveling of the conveyor floors 6,7 around another, one Opening of the conveyor floors 6,7 guaranteeing swivel axis 8,9 is just as conceivable as possible, as is pivoting the funding days 6.7 about a pivot axis 8.9 on the Side of the loading station 4 is facing away from the heating press is.

But it would also be conceivable, according to one not here illustrated embodiment, only one of the funding floors 6.7 to make a pivot axis 8 pivotable.

To load the loading station 4 with to be pressed Veneer batches 15, indicated by dash-dotted lines in FIG are, the promotion days are 6.7 around their respective Swivel axis 8.9 in the directions of arrow 12 Fig.1 pivots that between the funding levels 6.7 Opening angle arises.

The opening angle to be achieved between the two Funding days 6,7 should be chosen so large that all points of the lower funding level 7 are easily accessible are, i.e. equipping the lower funding level 7 can be done easily.

The loading of the loading station 4 with to be pressed Veneer batches 15, in this embodiment, by manually moving the veneer batches 15 to the Funding days 6.7.

First, the lower conveyor floor 7 is included Veneer batches 15 loaded, then both conveyor floors pivoted back into their horizontal starting position, so that now the upper conveyor floor 6 also with veneer batches 15 can be equipped.

One of the reverse procedures described above is but just as conceivable as equipping both at the same time Funding days 6.7 in the swung-out state.

The batches of veneer 15 to be pressed are to e.g. 12 to 24 sheets arranged one above the other, e.g. arranged in about 4 to 6 rows next to each other are.

After loading station 4 has to be pressed Veneer batches 15 and pivoting back of the conveyor floors 6.7 in its horizontal starting position, the heating press 2 is on opened the conventional way.

The batches of veneer 15 to be pressed are now so in Move horizontally in the direction of arrow 16 from FIG on the upper conveyor belt 10 of the loading station 4 lying veneer batches 15 on that, now with it in one Upper conveyor belt 17 of the heating press 2 in alignment arrive, and on the lower conveyor belt 11 of the Loading station 4 lying veneer batches 15 on that, now with him also lower conveyor belt lying in alignment 18 of the heating press 2 are spent.

After loading the heating press 2 with the veneer batches 15 is closed in a conventional manner. Of the Pressing can now be done by applying heat and Pressurization on both floors 23, 24 of the heating press 2 be started.

During the pressing process, it is conceivable and wanted that the Loading station 4 again with batches of veneer 15 to be pressed is populated, which ensures that after completion the pressing process in the heating press 2, the veneer batches 15a be transferred to the cooling press 3 and the heating press 2 can be refilled.

A long and therefore costly service life of the heating press 2 is thus avoided.

After completion of the pressing process in the heating press 2 these opened again in the conventional way.

The hot pressed veneer batches 15a can now be in the cooling press 3 connected to the heating press 2 in the direction of arrow 16 from FIG. 1.

Those lying on the upper conveyor belt 17 of the heating press 2 Batches of veneer 15a are placed on the one opened with it State of the heating press 2 and cooling press 3 on one vertical level upper conveyor belt 19 of the cooling press 3 spent, likewise those on the bottom Conveyor belt 18 of the heating press 2 lying veneer batches 15a to that with him now also in a vertical plane lying lower conveyor belt 20 of the cooling press 3.

At the same time, the heating press 2 is set to that described above Way from the loading station 4, with others too pressing pressing veneer batches 15, so that both Pressing processes in the heating press 2 and in the cooling press 3 can be started at the same time.

The are brought into the heating press 2 Veneer batches 15 in the manner already described below Heat and pressurization pressed into the Cooling press 3 spent veneer batches 15a at the same time cooled and pressed.

The loading station 4 can now also again during the now running pressing operations, in the manner already described and Refilled with veneer batches to be pressed will.

After completing the two pressing processes in the heating press 2 and in the cooling press 3 both pressing stations 2, 3 conventional way opened again.

The lying in the cooling press 3, now completely pressed Batches of veneer 15b are now based on the Cooling press 3 subsequent unloading station 5 in the direction of Arrow 16 from Fig.1 spent.

The lying on the upper conveyor belt 19 of the cooling press 3 Batches of veneer 15b are placed on the open with it Condition of the cooling press 3 in alignment with the upper one Funding days 21 of the unloading station 5 spent on the lower conveyor belt 20 of the cooling press 3 lying Veneer batches 15b on the with her now also in one Aligned lower conveyor floor 22 of the unloading station 5.

With the discharge of the finished pressed veneer batches 15b the cooling press 3 in the unloading station 5, this will be again with hot-pressed veneer batches 15a from the heating press 2 already described manner, as well as the Heating press 2 again with batches of veneer 15 to be pressed loaded from the loading station 4. A new placement of the Loading station 4 with further batches of veneer 15 to be pressed can now also be done.

The design of the unloading station 5 is that of the loading station 4 the same, in this embodiment it is a mirror image arranged to the loading station 4.

The unloading station 5 is in this embodiment from two superposed conveyor floors 21, 22 each about a pivot axis 27, 28 in the directions of the Arrow 29 from Figure 2 are pivotally mounted.

The pivot axis 27, 28 of the conveyor floors 21, 22 are in this Embodiment, the centers of the pulleys 30,31 one belonging to each of the funding days 21, 22 Conveyor belt 32,33 on the side of the unloading station 5 are arranged, which connect to the cooling press 3.

A pivoting of the conveyor floors 21, 22 of the unloading station 5 another, an opening of the funding floors 21, 22 ensuring pivot axis 27, 28, but is also conceivable as possible, also a pivoting of the funding floors 21.22 about a pivot axis 27.28 on the side of the Unloading station 5 is located, which faces away from the cooling press 3.

But it would be just as possible, according to one not here illustrated embodiment, only the upper conveyor floor 21 to make a pivot axis 27 pivotable.

To unload the now finished pressed veneer batches 15c In the unloading station 5, the conveyor floors 21, 22 are turned around their respective pivot axis 27,28 in the directions of Arrow 29 pivoted from Figure 2, between the Funding days 21, 22 an opening angle arises.

The opening angle to be achieved between the two Funding days 21,22 should be chosen so large that everyone Points of the lower funding level 22 are easily accessible, i.e. that unloading the lower conveyor floor 22 easily can be done.

The unloading station 5 is opened in this exemplary embodiment manual type unloading, first those on the upper conveyor floor 21 lying pressed Unload veneer batches 15c, then after swiveling the Funding days 21, 22 are those on the lower funding level 22 unload lying veneer batches 15c.

One of the reverse procedures described above is but just as conceivable as unloading both at the same time Funding days 21, 22, in the swung-out state.

Since both the funding days 6.7 of the loading station 4 and the Floors 23, 24, 25, 26 of the pressing stations 2, 3 are always filled, i.e. not standing empty is a continuous one Production sequence of the continuous press 1 according to the invention ensured a negligible low The machine life of the press station 2,3 is therefore everyone Given time to process a high throughput Veneer batches 15 is also through the use of Continuous press according to the invention guaranteed.

A further development of the continuous press according to the invention 1 by increasing one or more funding days the loading station 4 and at the unloading station 5 as well Add one or more conveyor belts and Press days at the press stations 2, 3 are also conceivable as possible.

Because of the configuration according to the invention, it is in the Continuous press 1 according to the invention possible, the individual Stations, in particular the pressing stations 2 and 3 to feed continuously.

Such a continuous feed can be such be made that in the presses 2.3 batches to be imported first into the loading station 4 be introduced, then, as described above, in the first workstation, i.e. Press station 2, spent too will.

During the pressing process, the loading station 4 can now again charged with batches to be brought into the press station 2 will.

After completion of the pressing process in the pressing station 2 then the batch located in the press station 2, according to a given length, e.g. corresponding the length of those located in the loading station 4 processed materials, this e.g. can be made such that the already in the Press station 2 spent batch there in whole or in part remains, while that existing in the loading station 4 Batch is already brought into press station 2, i.e. it are then in the press station 2 two to be processed Batches, whereby the batch introduced first is still in its entirety or only partially present in the first press station 2 can be.

Now the batches located in the pressing station 2 again or subjected to a first pressing process.

After the pressing process is completed, the press station 2 existing batches or those available in the press station Batches transported and new material in the Press station 2 spent from the loading station 4, the to processing batches arranged one behind the other will.

If it is forwarded appropriately, the first one arrives of the batches introduced into the pressing station 2 into the second Press station 3, it is quite conceivable that a part of the material to be processed with his, the first Press station 2 facing end remains in this.

Due to the way of working described above is a continuous pressing of the materials possible, i.e. it continuously runs directly adjacent to one another Material the press stations 2 and 3, it being quite it is conceivable that the material to be processed is both already partly in the first press station 2 and also in the Loading station 4 is arranged during the pressing process, it is also conceivable that the second press station 3rd material already partially in the Removal station 5 as well as in the second pressing station 3 remaining during the pressing process of the pressing station 3 is arranged.

Due to the inventive design of the entire system the loading station 4 of the first pressing station 2 of the second Press station 3 and the removal station 5 is one continuous processing of the material to be pressed, e.g. guaranteed regardless of the length of the individual batches.

The arrangement, i.e. Position of the material during the Pressing process depends on the length of the press stations and the length of the material to be processed.

Due to the design of the loading and unloading station 4.5 it is possible to process material in the pressing stations 2, 3 while it is still partially in the loading or partially is already arranged in the removal station 4.5.
