Abstract

The method involves forming an outer limiting element (15) through single-piece partial components formed from a cover layer (10) and a part of an upper belt (7). The element is connected with strip-shaped side wall elements (19, 20) forming a lateral wall section of a glide board before the connection of the limiting element with a tread surface lining and a lower belt of the glide board. The side wall elements are glued with a longitudinal side wall (22) of the cover layer or with the upper belt, where the side wall elements are glued with a damping layer that is made from plastic. An independent claim is also included for a method for manufacturing a glide board.

Description

The invention relates to a method for producing an outer limiting element for a gliding board body, such as a ski or a snowboard, and to a method for producing a gliding board body, in which this outer delimiting element is used, as specified in claims 1 and 10, respectively.

In the EP 0 850 785 B1 a method of manufacturing a multilayer composite body in the style of a ski, snowboard or rollboard is described. Here, an outer decoration complex is prefabricated for the composite body and this prepared decoration complex is subsequently joined together with the actual or viable reinforcement structure of the composite body. The connection between the decoration complex and the reinforcing structure takes place on the basis of a thermofusible resin during a Heizpresszyklusses. The multilayer, prepared decoration complex comprises a layer of transparent or translucent plastic printed on the back with sublimable colors. This printed plastic layer is bonded with the aid of an adhesive film for hot assembly with an optical contrast foil, between this contrast foil and the transparent outer plastic layer, a mesh is embedded. With these measures, a flow or creep of the adhesive film is to be avoided during the hot pressing operations, so that the printing inks remain at the back of the transparent plastic layer at their respective location.

Furthermore, is from the EP 0 774 365 B1 a manufacturing method for board-like sliding devices, in which also prefabricated an outer multi-layer decoration complex and is subsequently connected to the supporting structure of the board-like sliding device. To produce the decoration complex, a decoration is transferred by the method of printing sublimable colors on a transparent or translucent plastic layer. Subsequently, a contrast foil is glued under heat and pressure to the previously decorated with sublimation colors surface of the plastic layer. In order to obtain the final state of the board-like article, this prefabricated, multi-layered decoration complex under heat and pressure on the actual reinforcing structure of the board-like sliding device attached, wherein the temperature and pressure values are higher than the temperature and pressure values that were necessary for the realization of the decoration complex. Here, too, a multiple thermal load of the transparent, outer plastic layer or the sublimationsfähigen dyes.

The US 5,292,148 A and the US 5,496,053 A show generic sliding board body, in particular Schier, in which a structural combination of a shell or cap construction is provided in connection with at least one side cheek member which extends at least within the binding mounting portion of the ski. How to create such a sliding board body is not apparent from these documents. Such constructions are relatively expensive and prone to failure when using standard procedures for making multilayer gliding board bodies.

The present invention has for its object to provide a method for producing a sliding board body, in particular a ski or snowboard with combined shell and sidewall construction, which allows the most cost-effective and error-free production process to create high quality Gleitbrettkörper.

The object of the invention is achieved by a procedure according to the features of claim 1. A resulting from the procedural measures of claim 1 advantage is that a multi-layer or multi-part Gleitbrettkörper can be created, which despite a structurally relatively complex structure comprising a so-called shell or cap construction in combination with at least one side cheek element, relatively inexpensive and stable in production, in particular in compliance with high quality criteria, can be produced. In addition, the method sequence according to the invention allows a varied and yet relatively inexpensive production of Gleitbrettkörpern partial shell or cap construction in technical combination with at least one partially extending in the longitudinal direction of the sliding board body, designed as an independent component side cheek element. In particular, the prefabrication of the upper limiting element comprising the cover layer, at least a portion of the strength-relevant upper flange and at least one strip-shaped side cheek element enables a stable and cost-effective or qualitatively demanding production of Gleitbrettkörpern in a subsequent production cycle. In addition, by the connection of the at least one Side cheek element with the cover layer or with the lower flange in a separate or independent process step ensures a reproducible as possible or planned coupling between the cover layer and the respective side cheek element. In addition, by the connection between the cover layer and the at least one side cheek element in a separate production step, which is upstream of the compound of the prepared components of the entire gliding board body, the most accurate and permanent connection between said elements is accomplished. In particular, this filigree items or positioning which require high positioning accuracy, largely avoided, creating stable and high-quality production processes are created, which also can be completed or executed in a relatively short time.

Furthermore, a procedure according to the features specified in claim 2 is advantageous because it allows a perfect connection process with the remaining or final components of the sliding board body to be produced. In particular, this ensures a planned contour or shaping of the sliding board body to be produced to a high degree. In addition, unwanted resolutions or delaminations of the built-up in the upstream process step, outer boundary element avoided or kept back. Above all, delamination processes of a side wall element with respect to the cover layer or with respect to the lower flange can be reliably avoided or prevented, as a result of the preforming of the upper limiting element excessive Abreiß- or detachment forces between the cover layer and the at least one side cheek element minimized or avoided.

Through the further development measures according to claim 3, a respective the respective geometric conditions or the respective required or desired strength or bending stiffness properties corresponding side cheek element is created in a simple manner. In addition, a variety of technically and / or optically different side cheek elements can be adapted to the respective needs or requirements in a simple and cost-effective manner.

Of particular advantage are the measures according to claim 4, as this production-related tolerances can be compensated to a certain extent easily. Moreover, the tightness of the composite to be produced by a hot pressing operation is effectively improved over undesirable leakage of flowable hot melt adhesive or gradually hardening plastic. In addition, the leaktightness of the composite body with respect to the prevention of unwanted ingress of water in the structure of the composite body is reliably accomplished. Not least, the transmission of shocks or high-frequency vibrations, starting from the tread portion of the sliding board body in the direction of the top, reduced by these at least one damping layer, so that a corresponding manufactured Gleitbrettkörper increased comfort and quality requirements.

Furthermore, a procedure according to the features specified in claim 5 is advantageous, since thereby the final, proper shaping or the determination of the outline contour of the sliding board body can be made in a separate process step relatively accurately to the desired values or according to the planned geometry data. A decisive advantage of this measure is that, during the creation of the upper, prefabricated limiting element, there are low or easily fulfilled requirements for the positioning accuracy between the at least one side cheek element and the cover layer, so that the achievement of the most cost-effective production process is supported. In particular, even with relatively high positioning tolerances between the cover layer and the at least one side wall element in the end effect or final result, high-precision sliding board bodies corresponding to the respective desired geometry values can be created.

A further advantageous measure is specified in claim 6, as this spatially or geometrically relatively complex contours or cross-sectional curves can be created and a high reproducibility and quality of the corresponding produced Gleitbrettkörper can be achieved. In addition, this ensures that the side cheek elements can be supported on the inner molding surfaces of the Heizpressvorrichtung, so that the risk of destruction or damage of the adhesive bond between the side cheek elements and the top layer or the upper flange, for example due to the injection or expansion pressure of the foam plastic low is or is almost eliminated. Furthermore, an approach according to claim 7 or 8 of advantage, since an upper limiting element is created, which comprises a plurality of integrally interconnected components, which are useful for the production of a board-like winter sports equipment. In particular, by the measure, even the core element to stick to the underside of the upper flange preparatory, the production of a sliding device with technically combined shell side cheek construction failsafe as possible and at the same time cost. In addition, a relatively easy to manipulate, prefabricated, outer limiting element is created. In particular, the core element connected to the cover layer or to the upper belt stabilizes the cover layer, so that a relatively robust, prefabricated component is created, which simplifies handling in the course of the later connection process with the remaining components of the sliding board body to be produced.

Furthermore, the measures according to claim 9 are of particular advantage, since thereby the economy and the quality of a manufacturing process for a sliding board body, especially for a board-like winter sports equipment, can be significantly improved again. In particular, only one further heat pressing operation is required to complete the corresponding prefabricated semifinished product, which comprises the outer limiting element in conjunction with the core element, to form a corresponding composite body, which moreover comprises the tread surface and possibly edge elements and defines the structural basis for the gliding board body to be produced ,

Finally, the object of the invention is also achieved by the measures according to claim 10. In particular, this can be created Gleitbrettkörper with structurally combined shell and sidewall construction, which are produced as inexpensively as possible and thereby meet high quality criteria.

For a better understanding of the invention, this will be explained in more detail with reference to the following figures.

By way of introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or the same component names, wherein the disclosures contained in the entire description can be mutatis mutandis to the same parts with the same reference numerals or component names. Also, the position information selected in the description, such as top, bottom, side, etc. are related to the immediately described and illustrated figure and are to transmit this information in case of a change of position mutatis mutandis to the new situation. Furthermore, individual features or combinations of features from the different exemplary embodiments shown and described can also represent independent, inventive or inventive solutions.

In the Fig. 1 and 2 is an advantageous method comprising the inventive steps for producing a sliding board body 1, as in the Fig. 3 and 4 can be seen in excerpts, has been illustrated schematically.

Fig. 3 It represents some manufacturing steps known from the prior art for the creation of a gliding board body 1 according to the foam injection process (RIM, Reaction Injection Molding). In this case, strength-relevant and also decorative layers 2, 3, 4 using gradually hardening foam plastic, in particular PU foam, by means of a Heizpressvorrichtung 5 in a hot press cycle to a one-piece composite body 6 Fig. 3, 4 - joined together or glued together.

The strength-relevant layers 3, 4 are essentially an upper belt 7 and / or a lower belt 8 for the composite body 6 to understand. This so-called strapping can be formed by metallic layers and / or by a so-called "prepreg" in the form of resin-impregnated mats or the like. Depending on the desired mechanical properties, e.g. the deformation properties or strength properties, may optionally be performed only a top flange 7 or even a bottom flange 8.

As is known per se, at least one core element 9 of the composite body 6 is formed between the upper belt 7 and the lower belt 8. This core element 9 can, as is known, be formed from a plastic foam. According to the embodiments described later in detail, the core element 9 is formed of a wood material, in particular of a plurality of glued together wood slats.

In an initial process step, an outer cover 10 and optionally a tread 11 is selected from a plastic material which is at least partially transparent or translucent. The cover layer 10 and / or the tread surface 11 is in this case before the manufacturing process of the composite body 6 on at least one flat side with a decor or imprint 12, preferably according to the known from the prior art sublimation or Thermodiffusionsfärbeverfahren provided. For increased mechanical protection of the imprint 12, it is of course expedient to attach it to the back of the cover layer 10 and / or the tread covering 11.

If the composite body 6 is to be used as an alpine ski or as a snowboard, the tread surface 11, as is known per se, can be associated with lateral edge elements 13, 14, preferably of metal, in order to improve the guidance of the gliding board body 1 on snow and ice. Especially in the production of cross-country skis, these edge elements 13, 14 can be omitted.

At least the cover layer 10 constitutes an outer, upper limiting element 15 of the composite body 6 after the cover layer 10 forms at least a partial section of the outer surface of the sliding board body 1. But also the tread surface 11 is another, outer limiting element 16 of the sliding board body 1, after the facing away from the core element 9 flat side of the tread 11 forms the bottom side or lower surface, in particular the tread of Gleitbrettkörpers 1.

The method according to the invention relates to the production of the upper or cover-side, outer limiting element 15 for a generic sliding board body, such as a ski or a snowboard. This upper, production-technically prefabricated limiting element 15 is formed by an at least from the cover layer 10 and at least one component of the strength-relevant upper flange 7, one-piece component part. This production-technically prefabricated, upper limiting element 15 is connected in a subsequent process step or in a separate production cycle with the other components of the sliding board body, such as with its tread 11 and with its strength-relevant lower flange 8.

It is essential that an upper delimiting element 15 is prefabricated or preparatory for the gliding board body 1 to be produced subsequently, which additionally comprises at least one strip-shaped side cheek element 19, 20 forming a lateral wall section 17, 18 of the gliding board body 1. In particular, the upper limiting element 15 is in an independent process step before connecting to the rest Components of the sliding board body 1 with at least one, a lateral wall portion 17, 18 of the sliding board body forming, strip-shaped side cheek element 19, 20 is connected. In this case, the at least one strip-shaped side cheek element 19, 20 is glued to at least one longitudinal side edge 21, 22 of the cover layer 10 or with the upper belt 7 arranged on the underside of the cover layer 10, as shown in the exemplary, schematic representations corresponding to FIGS Fig. 1, 2 can be seen. This means that the cover layer 10, at least a part of the upper flange 8 and at least one strip-shaped side cheek element 19, 20, which forms the so-called side cheek of the later sliding board body 1, represents a prepared or pre-produced composite element, which in a subsequent method step with the other components of the gliding board body to be created 1 - Fig. 4 - is connected.

It is expedient, further, the prefabricated delimiting element 15, which comprises at least the cover layer 10, at least part of the strength-relevant top flange 7 and at least one strip-shaped side cheek element 19, 20, before the connection with the other components of the gliding board body 1 in an approximately U-shaped cross-sectional shape to convict. This can be done by suitable compression molding or by other forming processes. This forming process takes place in such a way that the lateral, longitudinally extending edge sections 23, 24 of the cover layer 10, together with the strip-shaped side cheek elements 19, 20 associated therewith, form the so-called legs 25, 26 of the limiting element 15 which is substantially U-shaped in cross section. In contrast, the so-called base of the substantially U-shaped delimiting element 15 is defined by the central portion or by the longitudinal center portion of the cover layer 10, as best of all Fig. 2 is apparent. The shaping process and the bonding process in relation to this composite element, which comprises at least the cover layer 10 and preferably at least two edge-side side cheek elements 19, 20, preferably takes place at least approximately simultaneously during the bonding of said elements, which preferably takes place with the aid of a molding press which heats or can be made unheated.

According to a suitable method measure, at least one strip-shaped side cheek element 19, 20 can be formed by gluing at least two superimposed, strip-shaped plastic profiles 27, 28. In particular, by two superimposed plastic profiles 27, 28 which are respectively most expediently considered shaping or cross-sectional height of the at least one side cheek element 19, 20 of the sliding board body 1 in a simple manner the respective requirements or geometric relationships and / or the respective desired strength properties.

Preferably, at least one side cheek element 19, 20 is formed per longitudinal side wall of the sliding board body 1, which in comparison to the cover layer 10 is formed physically independently or differently, as is apparent from FIG Fig. 4 is exemplified. Optionally, it is also possible to provide on at least one longitudinal side wall of the sliding board body 1 with respect to its longitudinal direction two or more side cheek elements 19, 19 'arranged one behind the other, wherein a predefined distance is preferably present between successively arranged side cheek elements 19, 19' Fig. 5 was exemplified. Within this distance between successively arranged side cheek elements 19, 19 'and 20, 20', the cover layer 10 is preferably pulled down to the top of the edge elements 13, 14 so that in this case the cover layer 10 on the top of the edge elements 13, 14 as directly as possible or supporting load.

According to a further-forming process measure, the at least one strip-shaped side cheek element 19, 20 in the course of production of the prefabricated, upper limiting element 15 at its lower and / or upper side with a damping layer 29, 29 'provided, in particular glued, as shown in the Fig. 2, 3rd indicated by dashed lines. This damping layer 29, 29 'consists of an elastomeric plastic, which is carried out in comparison to the plastic of the side cheek element 19, 20 comparatively resilient or resiliently restoring. This damping layer 29, 29 'serves, on the one hand, to damp vibrations, which, starting from the edge element 13, 14, are transmitted to the top flange 7 or cover layer 10 and subsequently to the foot of a user of the gliding board body. But also production tolerances can be compensated with this damping layer 29, 29 ', so that the most cost-effective and at the same time high quality standards expectant production of Gleitbrettkörpern 1, especially alpine skis, snowboards or cross country skis is possible. Another significant advantage of this development is that an improved Tightness of the composite body 6 is achieved, which on the one hand with respect to the prevention or reduction of the penetration of water in the internal structure of the sliding board body 1 has a positive effect, but also with respect to an avoidance or reduction of the escape of adhesive, such as PU Foams and / or synthetic resins is advantageous, which are present during the bonding of the prefabricated, upper limiting element 15 with the other components of the sliding board body 1, in particular with its lower limiting element 16, in a flowable or viscous state. This means that through this damping layer 29, 29 'and an undesirable leakage of adhesive during the final Heißverklebung or pressing of the upper, prefabricated limiting element 15 with the tread 11 and / or the lower flange 8 and with the edge elements 13, 14 starting from Core area of the composite body 6 in the direction of its outer or surfaces in an effective manner reduced or held back. Elaborate reworking or quality-reducing stains or adhesive accumulation can be minimized or completely prevented.

How best from a synopsis of Fig. 1 to 3 is apparent, the at least one side cheek element 19, 20 with the respective edge portion or longitudinal side edge 21, 22 of the cover layer 10 and the upper flange 7 in the course of prefabrication of the upper limiting element 15 glued such that a lateral projection 30, 31 of the cover layer 10th or the upper belt 7 with respect to the outer side or wall surface of the side cheek element 19, 20 is present. As a result, a rapid and relatively unproblematic connection, in particular bonding between the cover layer 10 or the upper belt 7 arranged therebelow and the web-like, strip-like side wall element 19, 20 can be made. In particular, this production simplifications can be achieved after a high precision or an increased positioning accuracy is not required. According to an advantageous method measure namely after the connection of the multi-part, one-piece limiting element 15 with the other components of the sliding board body 1, in particular after the injection of a foamed core element 9 or after the hot pressing process with a prefabricated core element 9 and the various components of the lower limiting element 16, the strip-shaped side cheek elements 19, 20 and in terms of amount usually varying projections 30, 31 at the longitudinal side edges 21, 22 of the cover layer 10 milled flush or ground flush, as best of Fig. 4 is apparent. In particular, the supernatant 30, 31 opposite the Au βenseite the adhered side cheek elements 19, 20 are eliminated, advantageously ground away or milled away after the one-piece composite body 6 has been produced, in particular after the composite body 6 produced in a hot pressing cycle has been demolded or removed from the heating press device 5.

By this milling or grinding process not only the protrusion 30, 31 is preferably removed, but expediently also an inclination of the outer side surface 32, 33 of the side cheek element 19, 20 produced in relation to a vertical plane and / or a surface treatment on the outer sides of the side cheek elements 19, 20 made. This means that after the production of the composite body 6 or after the removal of the same from the Heizpressvorrichtung 5 a material removal is performed or a machining both on the outer sides of the side cheek elements 19, 20 and on the longitudinal side edges 21, 22 of the cover layer 10 and the upper belt 7 is made. Preferably, between the running surface of the tread 11 and the outer side surface 32, 33 of the side cheek member 19, 20 included inclination angle 34, 35 between 60 ° to 85 °, preferably in about 75 °. In contrast, an inclination angle 34 ', 35' of the above the side cheek elements 19, 20 located sections or wall sections of the cover layer 10 relative to the tread surface 11 is made comparatively smaller, as best of Fig. 4 is apparent. The angle of inclination 34 ', 35' of the lateral sections or the lateral wall sections of the cover layer 10 is between 55 ° to 75 °, preferably in about 65 °. How best Fig. 4 can be seen, the side surfaces 32, 33 of the side cheek elements 19, 20 in conjunction with the lateral edge portions of the cover layer 10 each have stepped side cheeks and stepped side wall sections for the gliding board body 1, said gradation and the formation of the side cheek elements 19, 20th is only partially executed with respect to the total length of the sliding board body 1. The longitudinal extent of the side cheek elements 19, 20 per longitudinal side of the gliding board body is between 20% to 80%, preferably about 40% of the projected length of the gliding board body 1.

As already stated above, the upper limiting element 15 is already at least partially preformed before being introduced into the heating press device 5, in particular in such a way that a substantially U-shaped cross-sectional shape is present, as shown in FIG Fig. 2 was exemplified. The final shape of the outer boundary element However, 15 is created by injecting gradually hardening foam plastic, in particular by injecting PU foam with a defined injection pressure, in between the prepared boundary element 15, the edge elements 13, 14 and the lower flange 8 of the sliding board body 1 originally defined hollow or free space , This means that, inter alia, by the resulting in the curing of the foam plastic expansion pressure, but significantly by the injection pressure of the foam plastic, the outer boundary element 15 as completely as possible or relatively completely pressed against the inner molding surfaces of the Heizpressvorrichtung 5 or crowded. This means that the final shape of the outer delimiting element 15, which comprises at least the covering layer 10 and at least one side cheek element 19, 20 extending over a partial section of the longitudinal extent of the covering layer 10, is not created until during the heating press cycle to form the one-piece composite body 6.

In Fig. 6 is an advantageous further development measure for the specified method for producing the outer limiting element 15 for a sliding board body 1 illustrated. In this case, in addition to the connection between at least one strip-shaped side cheek element 19, 20 opposite at least one longitudinal side edge 21, 22 of the cover layer 10 or opposite to the underside of the cover layer 10 arranged upper flange 7, and the core element 9 or at least a portion of the core element 9 with the coupled upper limiting element 15, in particular adhesively connected - in a separate, the final hot pressing process for the complete composite body 6 temporally upstream process or production step. In particular, the upper, prefabricated delimiting element 15 is already glued to the core element 9 of the later composite body 6 before it is connected to the other components of the gliding board body 1, in particular before the connection with the edge elements 13, 14 or with the tread surface 11. The complete composite body 6 is created in at least one separate, later method step and then contains all functionally relevant elements or all layers of the sandwich-type sliding board body 1 to be produced.

According to this method measure, the prefabricated or prepared, upper limiting element 15 thus comprises at least the cover layer 10, at least one component of the strength-relevant upper flange 7, at least one side cheek element adhesively coupled thereto 19, 20 and also at least one component, preferably the main component, of the core element 9 for the gliding board body 1 to be subsequently produced.

An exemplary upper limit member 15 is shown in FIG Fig. 6 during its manufacturing phase, especially during the hot press cycle, shown schematically. It is expedient here for the core element 9 to be positioned in a receiving recess 36 of the heating press device 5 which is at least approximately adapted to the core element 9. Analogously, it is expedient to at least one side cheek element 19, 20, which is to be bonded to the underside of the cover layer 10 or with the underside of the upper flange 7, in particular to be glued, in an adequate, preferably separately executed receiving recess 37, 37 ' position.

By closing or activating the mold halves of the Heizpressvorrichtung 5 is then preferably simultaneously or at least approximately simultaneously at least one side cheek element 19, 20 and at least a portion of the core element 9 with the cover layer 10, in particular with the underside of the upper flange 7, which preferably by a so-called prepreg -Material is formed, integrally connected. This connection process is preferably implemented as a heat-bonding process.

Between the receiving recess 36 for the core element 9 and the at least one receiving recess 37, 37 'for the at least one side cheek element 19, 20, at least one separating web 38, 38' is formed, which separates the adjacent receiving recesses 36, 37 and 36, 37 'and preferably also serves as a support element for achieving or securing the desired contour of the cover layer 10 and the upper flange 7, as is made Fig. 6 is apparent. By means of these receiving recesses 36, 37, 37 'on the one hand, the core element 9 and the other at least one side cheek element 19, 20 sufficiently accurately positioned and during the hot pressing process, especially during the hot glue phase, which by applying a certain contact pressure against the cover layer 10 and relative to the resin-based upper flange 7, held sufficiently accurate and stable position. As a result, a stable and reproducible as possible or error-free production process is achieved.

Optionally, it is also possible to prepare an adhesion-promoting layer and / or a bottom flange 8 or a component of the later bottom flange 8 preparatory to the underside of the core element 9, as is also the case in FIG Fig. 6 was indicated by way of example.

In Fig. 7 is one compared to Fig. 6 illustrates essentially analogous manufacturing method. Unlike the execution after Fig. 6 will after the execution Fig. 7 at least one composed of a plurality of individual elements side cheek element 19, 20 bonded to the underside of the upper flange 7, while at the same time or at least approximately simultaneously a core element 9 is attached to the underside of the cover layer 10 and the upper flange 7. Here again, on the one hand, for the core element 9 and on the other hand for the at least one side cheek element 19, 20 at least one position-determining receiving recess 36, 37, 37 'in the Heizpressvorrichtung 5, in particular in the lower mold half of the Heizpressvorrichtung 5 is formed. According to an advantageous measure, therefore, the cover layer 10, at least a portion of the upper flange 7, at least one side cheek element 19, 20 and the core element 9 during a single, common Heizpressvorganges pressed together and glued together to form a one-piece semi-finished product.

After removal of this prefabricated limiting element 15 from the Heizpressvorrichtung 5 is at least in that area in which the separating web 38, 38 'was positioned, a hollow or free space, in particular a distance between the at least one side cheek element 19, 20 and the core element educated. This distance or this hollow or free space is filled in a subsequent process step to form the final composite body 6 with an adhesive, in particular with adhesive foam, as is known Fig. 8 is apparent. In particular, in Fig. 8 illustrates the manufacturing step, with which the prefabricated, upper limiting element 15 is connected to the remaining or further components of the composite body 6 and sliding board body 1. In this case, the prefabricated limiting element 15 is connected in an independent hot press cycle with the edge elements 13, 14 and the tread surface 11. In this process step, an adhesive, for example a resin-based or PU-based filler adhesive 39, is introduced or injected in deliberately defined cavities or free spaces. Among other things, this filling adhesive 39 also fills the predefined gap or free space between the at least one side cheek element 19, 20 and the side surfaces of the core element 9, so that a sufficiently stable coupling between the side cheek elements 19, 20 and the core element 9 is present. In the same way, the filler adhesive 39 serves to connect the underside of the core element 9 or the lower flange 8 on the underside of the core element 9 with the tread surface 11 or with the edge elements 13, 14 sufficiently stable or tear-proof.

After demolding the demgemäßen composite body 6 from the Heizpressvorrichtung 5, the supernatant 30, 31 is removed on the side edges of the composite body 6, in particular weggefräst or ground away, as shown in the course of the presentation in Fig. 4 was exemplified. The correspondingly machined composite body 6 then represents a product that is relatively close to the final state for the purpose of forming the generic gliding board body 1, in particular in the form of a ski or snowboard.
