The outer side of the conveyor belt device should always be understood to be the side that is actually in contact with the gypsum layer during operation. The term "external side" is understood so that when the gypsum board manufacturing apparatus is in operation, the respective "outer side" members (e.g., 'the forming webs) are oriented relative to the receiving gypsum layer. Another element at the side (eg, the carrier belt) is disposed. The outer side is configured to resist the gypsum layer (eg, its moisture). One central concept is to respectively form at least one forming web's plurality of forming webs, forming a portion of the outer side of the conveyor belt device and directly contacting the gypsum layer during operation. The forming webs are thus An integral part of the conveyor belt device is arranged to avoid synchronization, thereby simplifying the manufacturing operation of the gypsum board and improving the reworkability of the gypsum board manufactured. Preferably, the forming webs are separable. Mounted to the conveyor belt device. Thus (4) the configuration of the ride plates to be manufactured in a simple manner (4). In the simplest example, for example, a gypsum board can be manufactured by removing the forming webs There is no recess or bevel at all in the corresponding edge region. (4) Ground, when the frequency is made into a dragon plate, the spacing of the concave portions caused by the 201249622 type web can be in a particularly simple manner. It is changed by removing a single forming web. Of course, it is possible to fasten the forming webs on the conveyor belt device at a desired interval in each case to enable the production of a predetermined length of gypsum board. In this example, it is conceivable that Providing a detachable fastening operation at a position of any length of the conveyor device; optionally, individual fastening positions can also be provided to simplify the definition of equidistance and to observe separately. This allows the same gypsum board manufacturing equipment to be used for a plurality of gypsum boards, such as gypsum board lengths. Preferably, the webs are formed from a flexible material, such as plastic. In a preferred configuration, the gypsum board manufacturing apparatus includes at least one conveying member positioned downstream of the conveyor belt device, wherein the forming webs are preferably disposed exclusively on the conveyor belt device, If necessary, they are also positioned on the conveying member, respectively, on their respective sub-transport members. In order to adequately coagulate the applied gypsum layer, it is usually necessary to transport it over a relatively long distance (e.g., 80 meters to 450 meters). However, due to coagulation, the gypsum layer is hardened after a known distance to maintain the recess created by the forming webs. This allows the conveyor apparatus to exhibit, for example, 'at least 2 G%, preferably at least 鄕 and/or up to age, preferably up to 50% of the entire length of the conveyor belt assembly and the conveying member. The transport member is preferably positioned downstream of the conveyor device in the direction of travel. In operation, the gypsum layer is passed by the conveyor device to the delivery member. The conveying member itself is read and read by the child who can count the amount of money. The conveying member, the individual sub-conveying elements can be configured as 6 201249622, a conveying f or a roller conveyor. The following 'never exclusivity, exemplary embodiment is practicable for the overall arrangement of the conveyor belt arrangement and the conveying member: 1. Conveyor belt (forming and hardening), 2. Conveyor belt, 3 conveyor belt, Etc., then the roller conveyor 2. Conveyor belt (forming and hardening), 2 conveyor belts, 3_ conveyor belt (forming and hardening), and then the roller conveyor. Preferably, the conveyor belt device and/or the downstream sub-transport member, the downstream conveying member is a length of at least 1 m, more preferably at least 15 m', even more preferably 3 The metre and/or at most 9 metric meters, further preferably at most 3 metric meters, even further preferably at most 15 meters. The proposed lengths which have been shown to ensure that the gypsum layer is sufficiently hardened due to coagulation, respectively, drying'. In an alternative embodiment, the profiled web may be triangular or trapezoidal or rectangular cross-face. The trapezoidal cross-section is particularly preferred for producing a gypsum board system - when the gypsum layer is correspondingly subdivided to appear a bevel at its edge and (iv) [the special way is filled with putty, separately plastered. In a specific embodiment of the invention, the conveyor belt device has a rotary plate forming skin V which is rotated together with the conveyor belt device on the carrier belt and has profiled webs spaced apart from one another . The sheet forming belt may additionally have two laterally longitudinally forming webs, each joined to the ends of the forming webs, for example permanently or even integrally formed, thus φ the gypsum board component of the forming web (s_d Receiving 201249622 a bevel at a longitudinal edge thereof (parallel to the edge of the carrier belt) and a predetermined interval in the cross-sectional direction. In a particularly preferred configuration, the plate forming belt system is embodied in this view. Sub- or step-like, meaning that two longitudinally forming webs extending in parallel are joined at a predetermined interval via a web, so that in each case a rectangular opening is left in the sheet forming belt and the gypsum board component The bearing belt is docked directly in these areas. However, it will also be understood that the openings may be closed by a thin foil, respectively carrying a belt layer 'individually forming a continuous belt for the sheet forming belt and the longitudinal forming webs, respectively. The projections and the forming webs extend vertically therefrom. In an alternative configuration, the sheet forming belt has two lateral toothed belts 'in each of which are joined separately, either permanently or integrally, to the ends of the forming webs. The toothed belt represents a particularly simple and practical option for monitoring the synchronization of the two lateral edges of the components of the panel. For example, the synchronization is achieved purely mechanically, such as by providing a driving roller with a projection that engages a correspondingly formed gap of the toothed belt. However, alternatively, it is also understood that the two recessed belts are synchronized with each other by a sensor <RTIgt; detecting the recesses and providing an electronically controlled medium. For example, a perforated belt ' can be used instead of a toothed belt. In the configuration of the plate component having a toothed belt or a perforated section, the toothed belt sequentially perforates the section without affecting the shaping of the gypsum board component, so the gypsum board is composed A portion of the longitudinal edges and 8 201249622 are not configured to have any bevels or otherwise achieve planarization, such as by longitudinally forming the webs in parallel, respectively. A possible configuration may also be such toothed belts. The perforated sections are then permanently bonded thereto or have integrally formed longitudinally formed webs to enable simultaneous creation of bevels in the longitudinal edges of the gypsum board components. One or more smoothing means may be provided for smoothing the side of the gypsum layer against the side of the forming web. This allows for offsetting (slightly) deformations at the side edges of the forming webs due to the imprinting of the forming web, which counteracts the quality of the gypsum board. The forming web may have a height of from 0.2 mm to 2.8 mm, in particular from 1.8 mm to 2.5 mm and/or from 80 mm to 200 mm, in particular from 120 mm to 160 mm. PCT. The gypsum board thus allowed to be manufactured is particularly easy to process, and is sequentially coated with plaster. The above-mentioned operations are also solved by a method of manufacturing a gypsum board, wherein the method comprises providing a gypsum board manufacturing apparatus of the above type and applying a gypsum layer having a predetermined viscosity to the exterior of the conveyor belt apparatus The side, by this means, the forming web presses itself into it due to the weight of the gypsum layer itself. For these advantages, reference is made to the gypsum board manufacturing equipment which has been explained. Further specific embodiments are created by the scope of the patent application of these dependent claims. BRIEF DESCRIPTION OF THE DRAWINGS The invention will be described below with reference to further features and advantages in accordance with the exemplary embodiments, which are explained in detail by the drawings, in which: 1 is a schematic side view of a specific embodiment of a gypsum board manufacturing apparatus; FIG. 2 is a schematic side view of a second embodiment of a gypsum board manufacturing apparatus; A schematic plan view of a second embodiment of the present invention; FIG. 4 is a schematic side view of a third embodiment of a gypsum board manufacturing apparatus; FIG. 5 is a schematic plan view of the third embodiment; Figure 6 is a schematic side view showing a fourth embodiment of a gypsum board manufacturing apparatus; Figure 7 is a schematic plan view of the fourth embodiment; and Figure 8 is a molding web A side view of a first embodiment. I: Embodiment 3 The following description uses the same component symbols for the same components or components having the same function. Figure 1 illustrates a gypsum board manufacturing apparatus for making a gypsum board, particularly a plasterboard. A conveyor belt assembly 10 including a carrying belt 11 is shown. Positioned at the outer side, the forming web 12 (both of which are illustrated by way of example) is mounted on the carrier belt 11 and in other words via the mounting member 13. The carrier belt 11 is redirected via a first and a second deflector unit 14, 15. The forming webs 12 are of triangular cross-section and form corresponding recesses 17 in a layer of gypsum 16. A first cardboard strip 18 is initially supplied to apply the gypsum layer 10 201249622 to the conveyor apparatus 10. A wet plaster block 19 is applied thereto. A second cardboard strip 20 is applied to the gypsum block 19 in sequence. The δ meta-wet gypsum layer consisting of the first and second cardboard strips 18, 20 and the gypsum block 19 sinks on the forming webs I2 due to their own weight 'and therefore due to the inside of the gypsum layer 16 Displacement forms the corresponding concave portions Π. In this further process, the gypsum layer 丨6, in turn, the gypsum component is hardened by coagulation, thus retaining the concave portions 17. In this example, the gypsum layer resides on the outer side 50 of one of the conveyor belt units. An internal side is indicated by the symbol 6〇. In a separation step not shown in the figure, the gypsum layer 16 can thus be cut in the region of the concave portions 17, so that the individual gypsum panels form a bevel in the edge regions thereof. Furthermore, a device (also not shown) can be provided on the longitudinal edge thereof, so that it is located at an edge parallel to the running direction of the conveyor device, and is represented by an arrow 21 to form a slope into the plaster. Board component. After this separation step, the gypsum board will thus create a bevel or concave portion at all four of its edges. In the first embodiment according to Fig. 1, the forming webs 12 are directly mounted on the carrying belt 1 by the mounting members 13, and during the production process with the carrying belt U__ rotates with the same. For example, the mounting members 13 can be screws. Fig. 2 is a schematic side view showing a second embodiment of the gypsum board manufacturing apparatus. Figure 3 shows a top view. In this particular embodiment, the forming webs 12 (only two of which are shown by way of example only) are part of a sheet forming belt that is in the production process phase 11 201249622 for the carrier belt 11 Rotate together at the outer side. In the particular embodiment illustrated herein, the panel forming belt 22 has two side longitudinally shaped webs 28' that are permanently joined to the ends of the forming webs 12, respectively. In this configuration, the stone f-plate component is lightly longitudinal (parallel to the scale 25 of the belt u) and the _receiving-predefined slope in the direction transverse thereto, - The person's land (four) points or the concave part. In the present invention, the two longitudinal webs 12 are permanently fastened to the longitudinally formed webs, so that the two longitudinal forming webs 12 are held in a defined relative position relative to each other during rotation. Avoid that a forming web may rotate faster than the opposite. In the present embodiment, the rectangular recessed portion 29 is formed between the longitudinally formed webs 28 and the three blank forming webs 12. In the region of the recessed portions 29, the gypsum board component rests directly on the carrier belt 11 disposed below the sheet forming belt. In an optional embodiment, however, it is also possible to provide the recesses 29 to be filled, so that the sheet forming belt is realized as a continuous belt, wherein the longitudinal forming webs 28 and the forming The web 12 is assembled into a protuberance. The carrier belt 11 according to Fig. 2 is redirected via the deflector units 14, 15 already described. The plate forming belt 22 is guided (by way of example) to cover four (generally: plural) A deflector unit 23 that operates the carrier belt 11 within the sheet forming belt 11. The gypsum layer stays in this region of the sheet forming belt 22 (on the upper side of the apparatus in Fig. 2) which preferably contacts the carrier belt 11. Fig. 4 is a schematic side view showing a third embodiment of the gypsum board manufacturing apparatus 12 201249622. Figure 5 shows a top view of the same embodiment. In particular, as can be seen in Figure 5, a plate forming belt 22 is also provided in the present embodiment which is guided to rotate on the carrier belt n. In a variation of this embodiment as in the second or third embodiment, it is shown that a toothed belt 24 rotates in parallel with each other to replace the longitudinal forming webs 28. The toothed belts 24 are separately detachable from the ends of the forming webs in the present embodiment. The forming webs 12 can be secured to the toothed belts 24 in any suitable manner, such as by a separable adhesive. The use of the toothed belts 24 allows for ensuring that the two toothed belts 24 are mechanically or electronically controlled to rotate at substantially the same speed, thereby accurately maintaining the profiled webs 12 for the toothed belts 24. The rectangular arrangement, in turn, carries the longitudinal running direction of the belt U. The toothed belts 24 are thus operable (above) on the outer side of the longitudinally shaped webs (not shown in the drawings) which provide the gypsum layer at its longitudinal edges (and bearing The edges 25 of the belt 11 are parallel) to be beveled. In a further step configuration, it will also be appreciated that the longitudinally shaped webs are combined with the toothed belts 24 and are integrally formed in sequence. In a further step configuration, a plate forming belt 22 is proposed in accordance with Figs. 6 and 7, in which the toothed belt 24 is replaced with a perforated belt 27. Mechanical synchronization is achieved by arranging the perforated belts 27 in a sequential manner to change direction by configuring a wheel 26 having a pin (see Figure 6). The wheels 26 are preferably connectable to a drive shaft for the carrier belt 11 in a torque-locked manner. Figure 8 shows a side view of a forming web 12 of a preferred embodiment 13 201249622. The profiled web 12, as in accordance with Figure 8, is assembled as a (substantially) trapezoidal cross-section, wherein a baseline of the trapezoid can be from 80 mm to 200 mm (see arrow 40). A shorter side parallel to it can be from 30 mm to 80 mm (see arrow 41). In general, the trapezoid (see Figure 5) can have a relatively small base 0.5 of 0.5 mm (0.2 mm to 0.8 mm). The forming web 12 as in Fig. 8 likewise includes a trapezoidal concave portion in the gypsum layer. If the gypsum layer is sawn through about the middle of the trapezoidal concave portion, it will constitute an inward indicating edge. The protruding edge is preferably removed in a further sawing (or cutting) step so that the edge of the final gypsum board is beveled. It is emphasized at this point that all of the above-described components, whether individually or in any combination, particularly as illustrated in the drawings, are claimed as the essence of the invention. Those skilled in the art will be familiar with the modifications.
