Definitions
- the invention relates to a method of the type corresponding to the preamble of claim 1 and a corresponding system as are known from DE-PS 23 55 797.
- the invention is based on the object of designing a method and system of this type in such a way that the webs of smaller widths resulting from the plates can also be run on a double belt press of a predetermined nominal working width.
- the drop in temperature at the edge of the forming belts which was also caused by the lack of a plant there with smaller working widths and the associated poorer heat transfer into the forming belts, is avoided by the plant now being artificially manufactured there.
- heat continues to pass from the support structure to the form belts in the peripheral zone, so that the temperature drop does not occur or can in any case be limited to a harmless level.
- the system pressure does not have to be be exactly the same as the system pressure in the middle part of the width corresponding to the fill, although this would of course be preferable to create ideally equal conditions. However, it is also sufficient if the system pressure is only so high that the temperature can be kept at a value which limits the thermal stresses to an acceptable level.
- the arrangement of the forming tapes on the support structure under pressure, which ensures heat transfer, is produced in the invention with simple means, namely using the particles which are available in any case. Because of the character of these particles, this pressure is automatically adapted to the compression properties of the bed in the central region.
- the particles for the edge fill should be free of binders, because they would otherwise also harden and the hardened edge parts of the plate formed would have to be discarded, which is just as uneconomical as producing a wider plate from the outset and using a wide edge strip trimmed to the desired smaller width dimension.
- the particles for the edge fill can be taken from the supply for the main fill according to claim 2.
- the moisture content is namely of crucial importance for the amount of heat that is extracted from the forming belt, because the liquid, predominantly water, contained in the particles evaporates and the necessary for this Amount of heat must be applied. If the temperature of the edge zone of the forming tapes is to be kept high, it is advisable to ensure that as little heat as possible is lost for the evaporation of water in this area, ie the particles here, including the binder, have a lower moisture content than the particles of the main bed.
- the method according to claim 4 is recommended, according to which the particles of the edge fill are returned to the supply which also feeds the main fill, so that at least some of the particles of the edge fill are processed into a plate after a single pass new particles are used and essentially for the edge fill.
- FIG. 1 is a side view of a double belt press to which the invention is applicable;
- Fig. 2 is a vertical longitudinal section through the double belt press along the line II-II in Fig. 3;
- FIG. 3 is a cross section through the double belt press along the line III-III in FIG. 1;
- FIG. 4 is a partial cross section through the edge region IV provided with a dotted frame in FIG. 3;
- FIG. 5 is a partial top view of the transverse region of the bed marked V-V in FIG. 2;
- FIG. 6 is a chip flow diagram of the bed of FIG. 5.
- a double belt press for the production of chipboard, fibreboard and other plate-shaped materials which consist of particles bound by means of a binder which cures under pressure and heat. It comprises an upper forming belt 1 made of sheet steel of approximately 1 to 1.5 mm thick and a similar lower forming belt 2. Between the forming belts 1, 2, a web 4 from a bed 4 'is pressed in a pressing section 3, which consists of a pourable material which, after pressing, produces one of the aforementioned materials.
- the upper forming belt 1 runs around rollers or drums 5, 6 arranged transversely to the web 4, of which the drum 6 in a fixed stand 7, the drum 5 in one around a support 8 on the floor, and one running across the web 4 Axis pivotable stand 9 is mounted.
- the stand 9 is moved via the hydraulic cylinder 10 and the forming belt 1 is stretched in this way.
- the forming belt 2 runs over drums 11, 12 arranged transversely to the web 4, of which the drum 11 is mounted in a fixed stand 13, the drum 12 in a stand 14 movable on rails is.
- the stand 14 can be moved in the longitudinal direction to the web by hydraulic cylinders 15 and the forming belt 2 can be tensioned in this way.
- the form belts are driven by the drums.
- the forming belts 1, 2 run through the device in the sense indicated by the arrows 16, so that the bed 4 ′ applied to the right-hand side according to FIG. 1 by means not shown is drawn into the pressing section 3.
- the outgoing compressed web 4 is removed in the left area of the forming belt 2 according to FIG. 1 by suitable devices, not shown.
- an upper support structure 17 is provided in the inner region of the forming belt 1, which cooperates with a lower supporting structure 18 provided in the inner region of the lower forming belt 2.
- the support constructions 17, 18 support the areas of the forming strips 1, 2 facing the web 4 against the web and press them flatly against one another with great force.
- the support structures 17, 18 each consist of individual supports 19, 20, which are each arranged opposite one another above and below the form belts 1, 2 and the web 4 (FIG. 2). Each pair of supports 19, 20 is clamped by lateral spindles 21 (FIG. 3), so that individual pressure members which are self-contained in terms of force are formed.
- roller chains 30 are arranged between the mutually facing sides of the plates 26, 27 and the forming belts 1, 2, on which the forming bands 1, 2 roll relative to the plates 26, 27 and which run endlessly in a vertical longitudinal plane around the plates 26, 27.
- the rollers of the roller chains 30 transmit both the pressure and the heat of the plates 26, 27 to the forming belts 1, 2 and thus the web 4 that is being formed.
- roller chains 30 can either in the actual pressing area, i.e. between the carriers 19, 20 and the plates 26, 27 can be returned, as is indicated in FIG. 2 for the plate 26 and in FIG. 4.
- This embodiment has the advantage that the roller chains 30 maintain their temperature essentially constant during circulation.
- the plates 26, 27 are made of one
- Heating and support plate 43 and a separate return plate 44 with return grooves 42 for the roller chains 30 are constructed. It is a partial cross section through an edge region located above the web 4 according to FIG. 2.
- the plates 43 have the heating channels 40, which are connected to one another at the ends via pipe elbows 45 to form a closed conduit, and smooth running surfaces 41, which form the common rolling surfaces for the roller chains 30 arranged next to one another, which are shown in FIG. 4 are recognizable.
- the roller chains 30 roll between them and the mutually facing running surfaces 41 of the plates 43.
- Adjacent roller chains 30 lie directly opposite one another with their outer end faces.
- the right edge 31 of the bed and the plate web 4 according to FIG. 4 lies approximately at the level of the right edge of the roller chains 30.
- a bed 33 of wood shavings or other suitable particles is then applied in the usual manner to the forming belt 2, the width 38 of which is less than the nominal working width 34 and is characterized by the position of the edge 32 in FIG. 4.
- These wood chips or other particles are provided with binders, which is to be indicated in the drop area 39 in FIG. 2 and in FIGS. 4 to 6 by the dotted lines. If the filler 33 provided with binder ran into the pressing section 3, the molding tapes 1, 2 in the edge zone 35 (FIGS. 4, 5) lacked the counterpressure because the fill 33 is indeed narrower than the nominal working width 34. For this Basically, the heat would be transferred by the roller chains 30 in the outer edge zone to a much lesser extent into the forming belts 1, 2 and there would be a significant drop in temperature in the transverse direction with the corresponding thermal stresses in the longitudinal direction.
- edge beds 36 are sprinkled in the two edge zones 35 of the pressing section 3 which are not covered by the bed 33 and which extend outward from the edge 32 of the main bed 33 to the edge 31 of the pressing region and there a counterpressure deliver, which holds the forming tapes 1, 2 in the edge zones 35 in a comparable manner against the roller chains 30, as is the case in the area of the main bed 33.
- the material of the edge bed 36 is the same as that of the main bed 33. It is taken from the common supply 50 (FIG. 6) of unbelie ter chips via conveyor lines 51, from which the material for the main bed 33 is also withdrawn via the conveyor line 52. However, binder is added to the material for the main bed 33 before it is scattered in the conveyor section 52 from the binder supply 53. After passing through the press section 3, the main bed 33 is bonded to the plate web 4, while the material of the edge beds 36, which contains no binding agent, is still loose and spreadable. This material can therefore, after leaving the press section 3, be returned to the supply 50 via the return conveyor sections 54 and be mixed with the main amount there. It therefore takes part in the production of the sheet web 4 and does not circulate endlessly as a separate quantity only to form the edge beds 36.
- the moisture content of the particles for the edge beds 36 can, if desired, be set independently of the moisture content of the particles for the main bed 33, for example to a lower value, so that it is not so at the edge, by means of moisture regulating devices 55 connected into the conveyor sections 51 a lot of heat is lost for the pure evaporation of existing moisture and the desired temperature increase at the edge is easier to achieve.
