In this case, a substructure covered flush with a covering rosté is provided for mounting a handle, such as a door handle or a WC-door olive, which handle is coupled to a lock nut of a mortise lock for rotation thereof. The substructure is accommodated with an exact fit in a substructure receiving recess which is accommodated in a CNC-controlled manner in a door leaf body made of chip-removing formable material. In particular, the substructure is accommodated with an exact fit in a through-opening of the covering rosette, which is accommodated with an exact fit in a covering rosette recess produced by CNC milling.The object of the invention is to provide means by means of which a door leaf of the type shown in [5], which is improved with regard to function and optics, can be produced automatically on a large scale.To achieve this object, the invention provides a method, a subset, an apparatus, an arrangement and a computer program according to the appended independent claims.Advantageous embodiments are the subject matter of the dependent claims.According to one aspect thereof, the invention provides a method for the automated production of a door leaf, comprising the steps: a) providing a door leaf body which is formed from material which can be machined at least in a lock-side region; b) providing a mortise lock having a lock nut rotatably mounted therein; c) Provision of a substructure and a covering rosette, wherein the substructure is designed for the precise pivot bearing of a handle which is to be coupled to the lock nut, and wherein the covering rosette is designed for covering a substructure body of the substructure flush with the surface and allowing a radial relative displacement and has a covering rosette through opening which is bounded by an inner edge region and the diameter of which is greater than a through opening of the substructure, such that the position of a rotational axis of the handle can be selected in a radially variable manner with respect to the covering rosette; d) numerically controlled chip removal of a lock pocket for the lock into the door leaf body; e) numerically controlled chip-removing introduction of a substructure receiving recess on a broad side of the door leaf body with an inner contour which is complementary to an outer contour of the substructure but is dimensioned larger, such that, when the substructure is inserted, a radial play is present between the outer contour and the substructure receiving recess; f) numerically controlled chip-removing introduction of a covering rosette recess for the radially and axially matched flush receiving of the covering rosette; g) inserting and fixing the mortise lock in the lock pocket; h) inserting the substructure into the substructure receiving recess, i) radially positioning the substructure in the substructure receiving opening such that the center of the substructure through-opening is aligned with the axis of rotation of the lock nut and fixing the positioned substructure; and j) fittingly inserting the covering rosette into the covering rosette recess.The numbering of the steps with a), b),... is for easier referencing and is not intended to contain any information about a particular sequence of the steps. The individual steps can be carried out successively or in parallel or overlapping, as can be seen from the overall relationship.If the door leaf is provided with a handle only on one broad side-for example the side facing in the opening direction (strip side) or the side facing counter to the opening direction (counter-strip side), it is sufficient if a set of substructure and covering rose is provided for this broad side in step c) and the corresponding recesses are introduced for this substructure and this covering rose in steps e) and f). In most embodiments, at least one set of substructure and covering rose-in particular for a door presser as a handle-is provided per broad side of the door leaf in step c) and the recesses are respectively introduced on each of the broad sides in steps e) and f). For a door leaf with several handles, e.g. door presser and olive, a set of substructure and covering rose for the first handle, e.g. door presser, and a set of substructure and covering rose for the second handle, e.g. olive or coin slot element, can be provided on at least one of the broad sides; a common larger covering rose can also be provided for covering a first substructure for the first handle and for covering a second substructure for the second handle with a corresponding first and a second covering rose passage opening.In particularly preferred embodiments, step b) comprisesb1) providing the substructure with the substructure body and an insertion sleeve, wherein the substructure body has the substructure outer contour and a substructure body through-opening, the diameter of which is smaller than the diameter of the covering rosette through-opening, and wherein the insertion sleeve is designed for insertion with an exact fit into the substructure through-opening and has an insertion sleeve through-opening for rotary mounting the bearing section of the handle with an exact fit and a covering rim for supporting a front end of the handle and for covering the inner edge region of the covering rosette.It is preferable that in steps g) and h), the sub-structure body is inserted, positioned and fixed in the sub-structure receiving recess.It is preferred that the method further comprises the step following step j):k) Inserting the insertion sleeve into the sub-structural body through hole.Preferably, step b 1) comprises: providing the sub-structural body such that the side to be covered by the covering rosette is planar.In some embodiments, step k) is carried out at the production site; the door leaf is then already supplied with the inserted insert sleeve to the installation site, where the handle is then preferably mounted.Step k) can, however, also be carried out later, e.g. in the course of the provision up to the installation location. For example, step k) is carried out together with the mounting of the handle.The insertion sleeve can be inserted simply by axial insertion. However, it is also possible to screw the insert sleeve into the substructure body. For this purpose, in some embodiments it is provided that the substructure body passage opening has an internal thread and the insert sleeve has a matching external thread.The positioning in step i) can be carried out in different ways. In some embodiments, the position of the pivot axis of the lock nut is detected (measured) by any known manner of detection and the position is adjusted by means of a substructure mounting device - e.g. mounting robot or multi-axis handling device depending thereon. This can take place when the substructure, in particular the substructure body, is inserted into the recess or else later, before or after covering with the covering rosette.Preferably step i) comprisesi1) positioning the substructure with a positioning aid which is inserted into the lock nut with an exact fit on one side and receives the substructure passage opening with an exact fit in the position region of the substructure.Preferably step i) comprisesi2) fixing the substructure by means of adhesive.Preferably, a hot melt adhesive is used.Preferably step i) comprisesi3) Fixing the substructure by means of clamps.Preferably step i) comprisesi4) Fixing the sub-structure by clamping by fixing the covering rose in such a way that it clamps the sub-structure in the door leaf body.The clamping can be carried out in addition to or as an alternative to the adhesive bonding.Preferably, step f comprises:creating the outer edge of the covering rosette recess with a step, wherein a first step is matched to the thickness of the covering rosette and a second step provides space for an adhesive for fastening the covering rosette, wherein step j) fastening the covering rosette with the introduction of adhesive in the second step.According to a further aspect, the invention provides a door leaf part set for producing a door leaf, wherein the door leaf part set comprises as parts a door leaf, a mortise lock, at least one substructure and at least one covering rose, wherein the door leaf has a lock-side region made of material which can be machined, in which a lock pocket for receiving the mortise lock with an exact fit and at least one substructure receiving recess for receiving the substructure and a covering rose recess for receiving the covering rose flush (covering the wings) covering the substructure are milled in at least one of the broad sides; wherein the substructure is designed for the precisely fitting rotary bearing of a handle which is to be coupled to the lock nut and has a substructure outer contour which can be received with radial play in the substructure receiving recess, wherein the covering rosette can be inserted into the covering rosette recess in a flush and precisely fitting manner in order to cover a substructure body of the substructure inserted into the substructure receiving recess in the intended use in such a way that the substructure is not prevented from being displaced radially by the covering rosette, and has a covering rosette through-opening which is bounded by an inner edge region and the diameter of which is greater than a through-opening of the substructure, such that the position of an axis of rotation of the handle can be selected radially variably with respect to the covering rosette.It is preferred that the substructure is provided with the substructure body and an insertion sleeve, wherein the substructure body has the substructure outer contour and a substructure body through-opening, the diameter of which is smaller than the diameter of the covering rosette through-opening, and wherein the insertion sleeve is designed for insertion into the substructure through-opening with an exact fit and has an insertion sleeve through-opening for rotary mounting the bearing section of the handle with an exact fit and a covering rim for supporting a front end of the handle and for covering the inner edge region of the covering rosette.According to a further aspect, the invention provides an apparatus for the automated production of a door leaf, comprising a processing machine for numerically controlled machining of a door leaf body, a mortise lock mounting device for inserting and fixing a mortise lock into a lock pocket in the door leaf body, a substructure mounting device for inserting, positioning and fixing a substructure into a substructure receiving recess in the door leaf body, and a covering rosette mounting device for mounting a covering rosette into a covering rosette recess in the door leaf body for covering a substructure body of the substructure inserted into the substructure receiving recess in a flush manner; and electronic, numerical or computer-implemented control means, wherein the apparatus is configured for carrying out the method according to one of the preceding embodiments.According to a further aspect, the invention provides an arrangement comprising a device of the aforementioned type and a door leaf part set according to one of the preceding configurations.According to a further aspect, the invention provides a computer program comprising instructions which cause an apparatus of the aforementioned type to carry out the method according to one of the configurations explained above.Some advantages and technical effects of particularly preferred embodiments of the invention are explained in more detail below.Preferred embodiments of the invention relate to automatic assembly of such door leaves, as are shown in the literature reference [3] under the designation "Planar", or as are described and shown in the literature reference [5].For this purpose, in some embodiments of the invention, the flush-surface presser assembly "planar" as shown in [3] and [5] has been developed further and the design has been modified in order to make possible better machining and assembly.According to [1], the very majority of locks on doors, such as in particular rotary sash doors, are designed as plug-in locks-see literature references [1] and [2]. The locks for doors available on the market are manufactured with certain tolerances between the stud ends and the lock nut for cost reasons. In addition to the normal manufacturing tolerances, the tolerances also result from the inaccurate fastening of the lock case to the lock tulip. The interaction lock nut-trigger pin-trigger mounting, such as a trigger rod or door plate, must absorb these tolerances without impairing the function. For this purpose, the position of the push buttons is normally fixed only when the locks are mounted. Here, for example, work is carried out on the construction side, i.e. only on the construction site at the site of use, with hand-held drilling templates which have the reference point lock nut. By selecting the correct drilling diameters for the trigger fastening, adjusted to the selected trigger set, the desired form fit is given. However, this requires much manual work during production. Moreover, this procedure cannot be carried out with any type of doors, for example with doors of the type shown in [5] it is desirable to provide for milling of a receptacle for a door push frog (or some other pivot mounting of a door pusher on the door leaf) before the lock is inserted.If, as is desired in industrial, largely automated mass-production of door leaves, receptacles for pivot bearings of door handles (or also of other handles, e.g. WC olives) are produced, e.g. milled out, by machine on the door leaf, as is desired, e.g. for machine milling for flat-flush handle sets of the type known, for example, from [5] in the context of mass production of the doors, the tolerances of the individual locks to be used differently cannot be easily accommodated, so previously such machine bores or the like have to be produced with a larger drilling diameter than is predetermined by the handle manufacturers. As a result, no form-fit is possible between the door and the trigger, but only a force-fit. Over time, this can lead to a shaking of the rosettes, which can lead to mechanical damage to the surface of the door leaf or the rosette in addition to functional deficiencies. In conjunction with machine milling carried out in the course of automated production for receiving door handle mounts, such as in particular-but not only-for flush handle sets, for example of the type known from [3] and [5], the tolerances of the lock in the interaction lock nut-handle pin (e.g. handle square)-handle mount (in particular handle rosette) have an effect on the function of the handle set. Machine milling of the flush-surface rosette receptacles on a door leaf with a lock already mounted beforehand, at which a reference point for the lock nut would then be able to be tapped, is very difficult to implement and should be omitted best for safety reasons, in particular with wood doors or the like, since spark flight can occur when there is contact between the milling cutter and the lock with a corresponding risk of fire. One solution would be to reduce the tolerances on the lock, but this would lead to a considerable expense for the locks.In the case of the flush-surface presser clothing (e.g. planar), as is known from [3] and [5], these tolerances are currently absorbed and compensated during production by milling at the factory using templates and manual assembly at the factory. Consequently, a high level of human complexity is required for series production, so that production is complicated and expensive.In conjunction with machine milling for flat-flush trigger sets (e.g. planar), the tolerances in the interaction lock nut-trigger square trigger rod affect the function of the trigger set or are exhibited as differently wide joints or as function problems.Machine milling of the trigger sets (e.g. planar or even normal trigger sets) with mounted lock is not advisable for safety reasons (spark flight when contacting milling cutter and lock).Some embodiments of the invention provide a very accurate lock milling (example lock pocket) in the door leaf by CNC machining. Furthermore, flush-surface rosehette millings (example for covering rosehette recess and the milling of the substructure (example for substructure receiving recess) by means of CNC machining are likewise provided very accurately. At this time, both millings do not have a direct and precise relationship with the lock nut, including the corresponding tolerances.After the lock assembly, the planar substructure is positioned and fastened exactly with respect to the handle nut (or optionally also with respect to the handle nut for a bolt, for coupling, for example, with a WC olive).In some embodiments, the positioning takes place with the aid of a positioning aid, which can be constructed similarly to a pusher with a square. This positioning aid is inserted into the lock nut with an exact fit on one side and receives the inner diameter of the substructure with an exact fit in the position region of the substructure. The tolerances then present, between milling of the substructure in the door leaf and the positioned substructure (matching the lock nut), are absorbed by the fixing of the substructure, for example by means of adhesive, clamping or the like. This fixing can be effected, for example, by an assembly robot. The fixed substructure later also ensures the fixed mounting of the trigger assembly in the substructure.In some embodiments, the substructure in the region of the later rose, unlike the embodiment known from [5], is embodied in a planar manner (without a raceway for the pusher). Furthermore, the inner diameter of the substructure is somewhat larger than the subsequently associated trigger neck.In some embodiments, the associated rose has an inner diameter that is slightly larger than the inner diameter of the substructure. The difference between the two inner diameters is so great that the entire tolerances, for example from the lock or the production, can be accommodated without the edge of the rosette inner diameter protruding beyond the edge of the inner diameter of the substructure.In some embodiments, the present and visible deviation between the two inside diameters at that time is covered by an insert having a rim insert sleeve.This insert has an inner diameter matched to the diameter of the associated trigger neck, so that the trigger is subsequently guided precisely after assembly therein.The outer diameter of the insert is matched with an exact fit to the inner diameter of the substructure body.The wider rim covers the visible tolerances between the inside diameters of the rose and the inside diameter of the substructure body and also serves as a race and guide for the pusher. This also protects the rose from damage during the trigger actuation.In some embodiments, since the rosette only has to be positioned and fixed with an exact fit in the rosette milling with respect to the outer edge, this mounting part can also be implemented, for example, by means of mounting robots. The insert with the rim can be pressed in at the factory or can be added with the trigger assembly.It would also be conceivable for the insert to be equipped with an external thread and for the substructure body to be equipped with a matching internal thread, with the result that it cannot be inserted but rather can be screwed.In some embodiments, the outer edge of the rosette milling has a step. The first stage is tuned to the rosette thickness. The second step provides the necessary space to receive the adhesive for securing the rose.The first stage of rosette milling and planar sub-construction in one plane also enables rosettes to be automatically mounted which are not quite planar and somewhat flexurally soft. The adhesive ensures that the rose is held in the milling and that the rose rests with an exact fit on the inner and outer edges.For further features and functions, reference is made to [5], the embodiments of which become embodiments of the present invention by corresponding modification as indicated here. Other shapes and / or dimensions of the individual parts, as specified in particular in [6] or [7], allow other functions and designs (mini-rosettes, long-plate optics, etc.).Preferred embodiments of the invention relate, starting from [3] (the doors designated by planar), [5], [6] or [7], to further developed constructions and assembly techniques for flush-type trigger sets, which particularly preferably facilitate simpler, in particular automated, production in industrial mass-production technology without impairing the function, longevity, comfort, operability and / or high-quality optics.Exemplary embodiments are explained in more detail below with reference to the attached drawings. The following shows: FIG. 1 is a front view, on the first broad side - strip side - of a door with a door leaf to be manufactured with methods, devices, parts sets and arrangements according to embodiments of the invention; FIG. 2 shows an end view onto a lock end side of the door leaf in the region of a lock; FIG. 3 shows a view comparable to FIG. 2 of a door leaf of the door leaf before the mounting of the lock and of a door fitting for actuating the lock; FIG. 4 is a sectional view along the line A-B of FIG. 1 or along the line B-C of FIG. 1, wherein a substructure and a covering rose are mounted as parts of the door fitting, wherein FIG. 4 shows an embodiment of a door leaf to be produced by an automated production method in a production plant-even without a presser fitting or a WC olive fitting; FIG. 5 is an exploded view of the region of the door leaf shown in FIG. 4 with the parts of the door fitting to be mounted, in particular a substructure with a substructure body, a covering rose and an insertion sleeve and a trigger fitting (shape remaining free) which is usually to be mounted first on the construction side; FIGS. 6 to 8 show different views of an exemplary embodiment of the substructure body with exemplary dimensions; FIGS. 9 and 10 show different views of the region of the door leaf situated between A and B (or B and C) for receiving the door fitting with substructure receiving recess and covering rosette recess and exemplary dimensionings; FIG. 11 shows a side view of an exemplary embodiment of a positioning aid; FIGS. 12 and 13 show different views of an exemplary embodiment of the insert sleeve with exemplary dimensions; FIGS. 14 and 15 show different views of an example of the lock, as known in principle, for example from [2]; and FIG. 16 shows a schematic schematic schematic illustration of a device for automatically producing the door leaf.FIG. 1 shows an embodiment of a door 10 with frame 12 and door leaf 14 and flush door fitting 16.FIG. 2 shows an end view of the lock region of the door leaf 14, wherein a mortise lock 20, as shown in FIGS. 14 and 15 and explained in more detail in [2], is accommodated and fixed in a lock pocket 21 as the lock 18.FIG. 3 shows a view as in FIG. 2 of a door leaf 15 of the door leaf 14 without the lock 18 and without the door fitting 16, wherein the lock pocket 21 is shown with a lock recess 22 for receiving the lock dog 24 and a box recess 26 for receiving the lock box 28.FIG. 4 is a partial cross-sectional view taken along line A-B of FIG. 1, and a sub-structure 30 and a covering rosette 32 for covering a sub-structure body 34 of the sub-structure 30 in a flush manner are mounted as parts of the flush door bracket 16. The substructure 30 is designed for the exact pivot mounting of a handle 36 of the door fitting 16.FIG. 5 shows the region between A and B of the door leaf 15 and the parts of the flush door fitting 16 in an exploded illustration. A door presser 38 of a presser assembly 40 of selectable design is depicted here as handle 36, which can be coupled to a lock nut 44 of the mortise lock 20 by means of a presser pin 42-generally a square pin.As shown in particular in FIGS. 3, 5 and 9 and 10, a substructure receiving recess 46 for completely receiving the substructure body 34 and a covering cassette recess 48 for flush receiving the covering cassette so that it covers the substructure body 34 are introduced into the door leaf 15, which at least in the lock region consists of a material that can be machined, such as in particular a wood material.An exemplary embodiment with exemplary dimensions of the substructure body 34 is illustrated in FIGS. 6 to 7. In some embodiments, the substructure body 34 is hat-shaped, having a circular cylindrical main region 50 and a radially annularly projecting edge region 52 at the axial end region which comes into contact with the covering rosette. The axial end surface 54 on which the covering rosette 32 rests is planar, so that no form-fit with the covering rosette 32 is formed and thus the radial relative position of the substructure body 34 and covering rosette is not fixed, but is variable at least to certain tolerances. The substructure body 34 has a substructure body through-opening 54 for the introduction of the bearing region 56 of the handle 36.The bearing region 56 is formed, for example, at the free end of the handle neck of the door handle 38. Trigger fittings are available on the market from various manufacturers, wherein predetermined, in particular standardized, diameters of this storage region 56 exist for certain markets, for example the EU. For example, different door pressers 38 are available which have a bearing region 56 with a diameter of 16 mm on the handle neck.In some embodiments, the substructure body through-opening 54 is significantly larger than the predetermined diameter of the bearing region 56, wherein an insertion sleeve 58 with a cover ring 60 is provided, which can be inserted with its outer diameter into the substructure body through-opening 54 in a fitting manner. An embodiment of the insert sleeve 52 is shown in FIGS. 5, 12 and 13. The insertion sleeve 58 is, for example, hat-shaped, wherein the cover ring 60 protrudes radially at one axial end region and the other axial end 60 can be introduced into the substructure body through-opening 54 from the outside when the substructure body 34 is mounted and covered with the cover rod 32. This can be done by insertion or, if appropriate threads are provided, by screwing in.The axial end 62 facing away from the cover ring can be designed conically in order to facilitate an insertion of the insert sleeve 58 into the substructure body 34.In the following, the construction of the recesses 46 and 48 for the substructure 30 and the covering cassette 32 will be explained in more detail with reference to FIGS. 3 to 5, 9 and 10. The substructure receiving recess 46 has an inner diameter D46that is so much larger than the outer diameter D34of the substructure 30 (measured at the main portion 50 of the substructure body 34) that tolerances in the position of the pivot axis of the lock nut of the mounted lock 18 can be compensated for by adjusting the position of the substructure 30. Typical tolerances are obtained, for example, from [4]. Accordingly, in some embodiments, the inner diameter D 46 of the substructure receiving recess is at least 0.3 mm, preferably at least 0.5 mm, for example 0.5 mm to 2 mm larger than the outer diameter D 34 of the substructure, such that the radial position of the substructure can be variably selected in this range.In embodiments with a radially protruding edge region 52, this serves for the axial positioning of the substructure 32 by bearing on the edge of the substructure receiving recess 46 and accordingly has an outer diameter D 52 which is greater than its inner diameter D 34 but by at least the above-mentioned tolerance range, preferably significantly smaller than a minimum diameter of a radially outer boundary 64 of the covering rosette recess 48 axially adjoining the substructure receiving recess 46.The contour and depth of the covering rosette recess 48 is matched with the covering rosette 32 in an exact fit.In some embodiments, the mask rosette recess 48 is stepped. A first step 66, as seen from the broad side of the door leaf 15, has an inner contour 68 which is designed with an exact fit to the outer contour of the covering rose 32 and a depth T1 which corresponds to the rose thickness RD. The second step 70 has a smaller diameter so that an edge of the cover rod 32 can rest thereon and a depth T2 that is adapted to the thickness of the edge region 52. When the edge region 52 rests, a gap is formed between the latter and the radial delimitation of the second gradation, which gap offers space for receiving an adhesive (for example hot-melt adhesive).According to FIG. 5, the covering rosette 32 has a covering rosette through-opening 72, which is larger than the bearing region 56 by at least the above-mentioned tolerance range and is thus larger than the through-opening of the insertion sleeve 58 matched with the bearing region 56 in an exact fit.The outer diameter of the ring 60 is dimensioned larger than the inner diameter of the covering rosette through-opening 72 such that it can cover the covering rosette through-opening over the entire circumference at any variably selectable radial position of the substructure 30.The production and assembly of the door leaf 14 with the lock 18 and flush door fitting 16 will be explained in more detail below. In order to reduce costs, industrial mass production is desired, which can be carried out mechanically in a machine-driven manner as far as possible in an automated manner.In the illustrated embodiments, the substructure receiving recess 46 is formed continuously as far as the box recess 26. The recesses 21, 22, 26, 46, 48 are formed as milled cuts in the door leaf body 74, which is made from chip removing materials, such as wood materials, solid wood, HDF, MDF, chip board, plywood, veneer laminated wood, laminated wood, optionally surface-coated or veneered. Thus, recesses 21, 22, 26, 46, 48 to be provided in the door leaf body 74 for receiving the lock 187 and the door fitting 16 can be manufactured very accurately with very low tolerances by machine by numerically controlled machining, in particular CNC milling.Locks 18, 20 available on the market from various manufacturers have relatively large manufacturing tolerances on account of cost requirements, so that the position of the lock case 28 relative to the lock tulip 24 and in particular the position of the axis of rotation of the lock nut 44 is subject to relatively large tolerances. The different tolerances of the lock 18, 20 and the recesses 21, 22, 26, 46, 48 for the lock 30 and the door fitting 16 on the door leaf body 74 can result in mismatches in the rotational axis of the handle 36 defined by the recesses 46, 48 on the door leaf body 74 and the position of the rotational axis of the lock nut 44 determined by the lock case 28 and the tolerances of the lock 18, 20, which could impair the assembly of the trigger fitting, the longevity and the function of the combination lock-door fitting-trigger fitting.In order to facilitate machine manufacture and assembly and to counteract the aforementioned problems, a door leaf part set, shown in particular in FIG. 5, is provided for producing the door leaf, which has the door leaf 15, the mortise lock 20, the substructure 30 and the covering rose 32 as parts. The door leaf 15 has the lock-side region made of material which can be machined, in which the lock pocket 21 for precisely fitting reception of the mortise lock 18 and a number of substructure receiving recesses 46 matched to the number of pivot bearings of the door fitting for receiving the respective substructure 30 for pivot bearing are milled with corresponding covering rosette recesses 48 for receiving the covering rosette 32, which covers the substructure 30, in particular the substructure body 34.The substructure 30 is designed for the precisely fitting pivot bearing of the handle 36 which is to be coupled to the lock nut 44. The substructure 30 has a substructure outer contour which can be received with radial play in the substructure receiving recess 46.The covering rosette 32 can be inserted into the covering rosette recess 48 in a flush and accurately fitting manner in order to cover the substructure body 34 of the substructure inserted into the substructure receiving recess 46 in the intended use. The substructure 30 through the covering rod 32 does not engage with each other and are thus not prevented from mutual radial displacement. In other words, despite the position of the covering rosette with an exact fit, the radial position of the substructure during assembly is variable in order to compensate for the tolerances and adapt to the position of the axis of rotation of the lock nut 44. The through opening 72 for the covering rosette, which is bordered by an inner edge region, has a diameter which is larger than the through opening of the substructure 30 designed for supporting the handle, so that the position of the axis of rotation of the handle 36 can be selected radially variably with respect to the covering rosette. Thus, the substructure can be adapted to the position of the lock nut during assembly and be fixed in a fitting manner.The sub-structure 30 is provided with the sub-structure body 34 and the insertion sleeve 58 in some embodiments. The substructure body 34 has the substructure outer contour and the substructure body passage opening 54. The diameter of the latter is smaller than the diameter of the covering rosette through-opening 72, and the insertion sleeve 58 is designed for fitting insertion into the substructure through-opening 54. The insertion sleeve 58 has an insertion sleeve through-opening 76 for precisely fitting rotary mounting of the bearing section 56 of the handle and the cover ring 60 for supporting a front end 78 of the handle 36 and for covering the inner edge region of the cover rod 32.This allows an exact and play-free rotational mounting of the handle 36 to be achieved, so that the door gives a high quality impression and can be actuated conveniently and comfortably.Although the compensation of the lock tolerances has been explained on the basis of the example of the trigger assembly, corresponding measures can also be carried out for other handles, for example for toilet olives-see [5] for further details. FIG. 10 shows the shape of the substructure receiving recess 46, as they are formed for substructure 30 for the rotary mounting of push-button fittings or of toilet olives. A through-recess 82 is shown with a dot-dash line, as it is provided in the region of a keyhole 80 of a Buntbar's mortise lock or of a lock cylinder of another corresponding mortise lock.A method for the automated production of the door leaf 14 comprises the following steps:a) providing the door leaf body 74 (as a blank) which is formed from material which can be machined at least in a lock-side region;b) providing the mortise lock 20 with a lock nut 44 rotatably mounted therein;c) providing the substructure 30 and the covering rose 32;d) numerically controlled chip-removing introduction of the lock pocket 21 for the lock into the door leaf body 74;e) numerically controlled chip-removing introduction of the substructure receiving recess 46 on at least one broad side of the door leaf body 54 with an inner contour which is complementary to an outer contour of the substructure 30 but is dimensioned larger, such that, when the substructure 30 is inserted, a radial clearance is present between the outer contour and the substructure receiving recess 46;f) numerically controlled chip-removing introduction of the covering rosette recess 48 for the radially and axially accurately fitting flush-fitting receiving of the covering rosette 32;g) inserting and fixing the mortise lock 20 in the lock pocket 21;h) Inserting the sub-structure 30 into the sub-structure receiving recess 46,i) radially positioning the sub-structure 30 in the sub-structure receiving opening 46 such that the center of the sub-structure through-opening 54 is aligned with the axis of rotation of the lock nut 44 and fixing the positioned sub-structure 30; andj) Fitting the covering rosette 32 into the covering rosette recess 48.In some embodiments, step b comprises:b 1) Providing the sub-structure 30 including the sub-structure body 34 and the insertion sleeve 58 At this time, in steps g) and h), first, only the sub-structure body 34 is inserted, positioned, and fixed in the sub-structure receiving recess 46. After step j), the further step is carried out:k) Inserting the insertion sleeve 58 into the sub-body through hole 54.In some embodiments, the sub-structure is positioned with a positioning aid 84, an embodiment of which is shown in FIG. 11, an embodiment of which is shown in FIG. 11. The positioning aid 84 has a pin projection 86 which is preferably provided with a conical insertion end 87 and which projects from a fitting body 88, the outer contour of which is matched with an exact fit to the substructure body passage opening 54. For assembly, the substructure body 34 can be placed on the fitting body 88 and mounted with the positioning aid, wherein the pin protrusion 86 is inserted into the lock nut 44 of the previously mounted lock. Different procedures are possible. The positioning aid can also be introduced first, for example, and the substructure body 34 is then placed on and pushed axially into abutment. The substructure body can also be inserted initially in an unpositioned manner and covered with the covering rosette. Before the fixing takes place, for example by curing the adhesive or by tightening a clamping (e.g. pressing the covering rose), the positioning aid is introduced and thus the radial position of the substructure body 34 is adapted to the position of the axis of rotation of the lock nut. The fixation is then carried out.FIG. 16 schematically shows a possible structure of a device 100 for the automated production of the door leaf 14. The device 100 is, for example, part of a door manufacturing line in a manufacturing facility, wherein a conveyor belt 102 can be provided for conveying the door leaf body 74 through individual stations.The device 100 comprises a processing machine 104, for example a processing center, for numerically controlled machining of the door leaf body 74 in order to introduce the recesses 21, 22, 26, 46, 48, a mortise lock mounting device 106, for example with a first mounting robot, for inserting and fixing the mortise lock 20 into the lock pocket 21 in the door leaf body 74, a substructure mounting device 108, for example with a second mounting robot, for inserting, positioning and fixing the substructure 30 into the substructure receiving recess 46 in the door leaf body 74: a covering rosette mounting device 110, for example with a third mounting robot, for mounting the covering rosette 32 in the covering rosette recess 48; and electronic, numerical or computer-implemented control means 112 which control the device 100 for carrying out the method explained above.For this purpose, some embodiments have a controller 114 with processor 116 and memory 118, in which a computer program with corresponding control instructions is stored.In some embodiments, an adhesive applicator 120 is provided for applying adhesive in the mask rosette recess 48. An assembly robot of the sub-structure assembly device 108 is configured to insert and position the sub-structure body 34 with the aid of the positioning aid 84. The adhesive already provides adhesion in this case, so that the position is maintained until the mounting robot of the covering cassette mounting device 110 mounts and presses the covering cassette and thus additionally fixes the substructure body 34 by clamping. A press 122 can also be provided for pressing the lock region until the adhesive has cured or cured.The insertion sleeve 58 can be delivered together with the door leaf 14 and transported to the construction site. It can also be provided with the trigger clothing. The insertion of the insertion sleeve 58 can thus take place during the assembly of the trigger assembly, for example at the construction site.In some embodiments of the apparatus 100, an insertion sleeve mounting device 124 is provided, which is configured to insert the insertion sleeve 58 into the substructure body 34 even at the manufacturer's factory after mounting of the covering rosette 32.The embodiments shown in the figures show only a standard version of the door leaf 14. In other words, the measures for improving automated manufacturing described here in the claims and the drawings can also be applied to the other variants described in [5], [6], [7]. For further features of further embodiments of the invention, reference is thus expressly made to these references [5], [6] and [7].To improve a series production of door leaves of high quality with high-quality optics, the invention provides a method, a device, a set of parts, an arrangement and a computer program for the automated production of a door leaf with a leaf-covering door fitting. In this case, recesses (21, 46, 48) for receiving lock and door fittings are first made by numerically controlled machining into a door leaf body (74) made of material which can be machined; a mortise lock (20) is then mounted in a lock recess and a substructure and a covering rose (32) are subsequently mounted in recesses on the broad side of the door leaf (15), wherein the substructure is inserted with play into a substructure receiving recess with radial play, positioned and fixed therein in alignment with a position of a lock nut (44). In some embodiments, the substructure for supporting a handle (36) has an insertion sleeve (58) with covering collars (60) which covers radial gap at an inner diameter of the covering rod which is to be provided for tolerance compensation.List of reference numbers:10 Door 12 Frame 14 Door leaf 15 Door leaf 16 Door fitting 18 Lock 20 Mortise lock 21 Lock pocket 22 Lock recess 24 Lock lip 26 Box recess 28 Lock box 30 Substructure 32 Cover rod 34 Substructure body 36 Handle 38 Door lever 40 Trigger fitting 42 Trigger pin 44 Lock nut 46 Substructure receiving recess 48 Cover rod recess 50 Main region 52 Edge region 54 Substructure body passage opening 56 Bearing region 58 Insertion sleeve 60 Cover ring 62 Free axial end 66 First step 68 Radially outer boundary 70 Second step 72 Cover rod passage opening 74 Door leaf body 76 Insertion sleeve passage opening 78 Front end 80 Keyhole 82 Passage recess 84 Positioning aid 86 Pin projection 87 Conical insertion end 88 Mating body 100 Apparatus 102 Conveyor belt 104 Processing machine 106 Mortise lock mounting device 108 Substructure mounting device 110 Cover slide mounting device 112 Control means 114 Controller 116 Processor 118 Memory 120 Adhesive application device 122 Press 124 Mortise sleeve mounting device D 34 Outer diameter Substructure D 46 Inner diameter of the substructure receiving recess D 52 Diameter Edge region T 1 Depth first step T 2 Depth second stepReferences included in the specificationThis list of documents cited by the applicant has been produced in an automated manner and is only included for the better information of the reader.
