Description

[Technical field]

[0001] The present invention relates to a method for manufacturing a component, preferably for sports equipment, an outsole manufactured by said method, as well as a method for manufacturing a sports shoe using said outsole and a sports shoe. [Background technology]

[0002] The manufacture of sporting goods such as athletic shoes involves multiple steps and processes. Various manufacturing processes are known in the art. For example, for athletic shoes, the first step is to design the outsole, which includes determining its shape, dimensions, tread pattern and other characteristics. This includes the selection of materials to be used in the manufacture. Nowadays, outsoles are usually made of various types of rubber or synthetic compounds. The choice of material depends on factors such as the desired level of traction, durability, flexibility, weight and specific performance requirements.

[0003] Outsoles, as well as other sports equipment, are usually made using injection molding. For this purpose, the material for molding is produced by mixing the selected rubber or synthetic compound with fillers, plasticizers, stabilizers and colorants well known in the art. The produced material is then injected into a mold cavity using an injection molding machine. After the mold is cooled to solidify the material, the sole is further processed, for example by cutting off the edges. In a further process step, the produced outsole is then integrated into the shoe manufacturing process by attaching it to the midsole, upper or other elements of the shoe using adhesives, stitching or other assembly techniques.

[0004] Several prior art documents, such as WO 2005 / 090062, China Registered Utility Model No. 216416187, and WO 2019 / 106837, relate to sports goods, such as outsoles for shoes, manufactured using injection molding.

[0005] Different approaches in this context have been described in the prior art, in particular in the prior art documents Italian Patent No. 1402354, Chinese Patent Application Publication No. 109228445 and US Patent No. 11278081. Italian Patent No. 1402354 describes a method for reinforcing and waterproofing a shoe and a shoe with a coating. Chinese Patent Application Publication No. 109228445 discloses a shoe sole treatment method of the dip-bonding type. US Patent No. 11278081 describes a sole for an article of footwear comprising successively dispensed components forming a first layer and a second layer.

[0006] However, a common disadvantage of these soles is that the final sole has a specific weight and thickness to give the required shoe durability and performance, which significantly impacts the total weight of the shoe. Another common disadvantage of these soles is that they are not sustainable since the shoe is designed to be discarded after use. Furthermore, the material properties cannot be easily changed during the manufacturing process to adapt the sole to the diverse requirements of sports equipment. Also, the sole is usually manufactured in multiple independent steps, which overall makes it a labor-intensive and inefficient process.

[0007] SUMMARY OF THE PRESENT EMBODIMENTS It is therefore an underlying object of the present invention to provide an improved method and sporting goods in order to at least partially overcome the above-mentioned drawbacks of the prior art. [Prior art documents] [Patent documents]

[0008] [Patent Document 1] International Publication No. 2005 / 090062 [Patent Document 2] China Registered Utility Model No. 216416187 [Patent Document 3] International Publication No. 2019 / 106837 [Patent Document 4] Italian Patent No. 1402354 [Patent Document 5] China Patent Application Publication No. 109228445 [Patent Document 6] U.S. Pat. No. 1,127,8081 Summary of the Invention [Problem to be solved by the invention]

[0009] The above problem is at least partially solved by a method for manufacturing a component, preferably for sports equipment, comprising the steps of: a.) providing a polymer; b.) providing a solvent; c.) mixing the polymer with the solvent, thereby producing a liquefied polymer; and d.) hardening the liquefied polymer, thereby producing the component.

[0010] In the above-mentioned prior art, the manufacture of components, for example outsoles for sports equipment, is usually carried out, for example, by injection molding a first component onto a second component, but such a process is not flexible to the special needs of the product. The present invention is based on a different approach, namely the manufacture of a liquefied polymer by mixing a polymer with a solvent, which is applied to the sports equipment and cured. In this way, the liquefied polymer can be applied to the sports equipment more precisely and effectively, for example, so that no waste of material occurs by cutting off excess material. In this way, the method according to the present invention provides an improved method for the manufacture of components, for example, for sports equipment, by consuming only the required amount of material and avoiding wasteful production.

[0011] Furthermore, no manual assembly is required and application without adhesives is possible, providing an efficient process with reduced material consumption and therefore lower overall costs, which is amenable to automated processes. Bonding can require complex pre-treatment of the components, and furthermore, adhesives used to bond plastic components are often hazardous or environmentally harmful.

[0012] According to this approach, the components can be provided and cured more than once, which allows the strategic production of components with different thicknesses and weights, while significantly improving the performance and durability of the sports equipment and maintaining or enhancing its cushioning. In this way, the method allows for a flexible approach to different needs and requirements of the product, while allowing a manufacturing method without a mold. The claimed invention therefore significantly simplifies the overall process of manufacturing components, preferably for sports equipment, while increasing the sustainability of the entire process, since it allows the regeneration of worn products, i.e. recoating and reapplication of the components. This is very helpful to extend the life of the sports equipment by regenerating the respective components. Finally, this also helps to reduce the overall generation of waste by the consumer. By choosing sustainable starting materials (polymers, solvents) in the method, the manufactured components and the sports equipment become recyclable and are manufactured in a sustainable manner. Furthermore, the inventors have found that the components can be given a glossy and / or shiny appearance, which is advantageous from a visual point of view.

[0013] Therefore, the whole manufacturing process of sports equipment using the method according to the invention can be more efficient and sustainable. The method according to the invention gives the possibility that the curing process applied to the various parts of the sports equipment can be easily adjusted, so that the components can be cured to the sports equipment without wasting excessive amounts of energy and time. Furthermore, the method of the present disclosure gives the possibility to create patterns and designs by using components whose design and shape can be varied. For example, the components can be transparent, opaque, monochromatic or multi-colored and can be personalized by the consumer.

[0014] A "component" according to the present disclosure is a unit or module that performs a specific function within a larger system, including but not limited to, components used in the manufacturing process of sports equipment, such as sole units, midsoles, outsoles, outsole elements, membranes or foils, sole plates, shoe uppers, functional elements, etc.

[0015] "Sports goods" according to the present disclosure is understood to be, but is not limited to, any equipment, gear or product specifically designed and / or used for sports, such as sportswear, athletic shoes, sports accessories and / or sports equipment.

[0016] A "polymer" according to the present disclosure is a large molecule based on repeating subunits (monomers) that are linked together to form a network structure, including but not limited to: Polymers can be classified as follows: synthetic polymers, natural polymers, biodegradable polymers, and composite polymers.

[0017] A "solvent" according to the present disclosure is a compound that can dissolve, disperse, or extract other compounds, including but not limited to, a solvent. Solvents can be polar or non-polar. Typical solvents are in liquid form, but can also be gases or solids.

[0018] "Mixing" in accordance with the present disclosure is understood to mean, but is not limited to, the process of combining two or more substances into a mixture of individual substances.

[0019] "Curing" in accordance with the present disclosure is understood, but is not limited to, as a chemical and / or physical process of a material that typically promotes the hardening, setting and / or solidification of the material.

[0020] In some embodiments, the method may further comprise a step of depositing the liquefied polymer obtained in the mixing step, which may be the first component of the sports equipment, onto a second component of the sports equipment. The depositing step may precede the curing step. "Depositing" or "deposition" according to the present disclosure is understood as, but not limited to, a process of applying / applying one or more elements onto one or more other elements. Such an embodiment may greatly simplify the process of manufacturing the components. For example, the liquefied polymer may be deposited with different physical properties before the polymer is cured on the sports equipment, increasing the efficiency of the manufacturing process. Moreover, these method steps may be performed in one device or in different entities, giving a high degree of flexibility and automation in the manufacturing process.

[0021] The method may further comprise a step of texturing the liquefied polymer obtained in the mixing step, which may precede the curing step. "Texturing" or "structuring" according to the present disclosure is understood as a process of manipulating the physical properties of an element by external influences, such as, but not limited to, shape, pattern and / or surface. The inventors have found that the addition of texture and structure can significantly improve the performance and durability of sports equipment, since the thickness of the applied layer can be adapted to the product requirements, such as weight, wear resistance and design. The texturing can be performed using common texturing devices, such as pattern brushes and / or pattern rollers. The choice of the texturing device depends on the desired pattern and / or the physical properties of the liquefied polymer.

[0022] In some embodiments, the sports equipment may be an athletic shoe. The athletic shoe may be, for example, a football shoe, a basketball shoe, a running shoe, a tennis shoe, a motorsport shoe, a hiking shoe, etc. The inventors have found that the method of the present invention, when applied to an athletic shoe, significantly improves the life and durability thereof and reduces the overall weight of the athletic shoe. The component may be a sole, preferably an outsole, of the athletic shoe. In this way, the sole may be manufactured by the method of the present disclosure, allowing for uniform or homogeneous and higher durability properties by using one or more soles and / or outsoles that are lighter and thinner compared to conventional soles known in the art.

[0023] In some embodiments, the athletic shoe may be a football shoe. In this way, the football shoe exhibits enhanced physical properties compared to football shoes known in the art. In particular, the inventors have found that by following this approach, the football shoe is lighter while retaining performance characteristics comparable to or better than those of a normal football shoe.

[0024] In some embodiments, the components may be the studs of a sneaker, which offers the advantage of being lighter while retaining similar or better performance characteristics than a regular studded sneaker, as well as the possibility of recoating and / or refurbishment of each stud individually. Depending on the various needs of the product and / or the consumer, the studs may be individually shaped and textured. In this way, each sneaker with studs can be strategically and conceptually designed and thus subjected to improved methods.

[0025] In some embodiments, the liquefied component may be deposited in one or more parts of the sports shoe. The parts may include a toe part, a forefoot part, a heel part, a midsole part, a sidewall part, and / or an upper part. A "liquefied component" is understood as a component having, but not limited to, semi-solid physical properties and / or a liquefied polymer according to the present invention. In this way, the sports shoe may have individual sole elements that can be adapted and reapplied. The liquefied component may be deposited in predetermined parts of the sports equipment. For example, the liquefied component may have different physical properties for each of the predetermined parts. In this way, the sports equipment may be conceptually adapted, allowing a sports equipment with a lighter overall weight while increasing its durability and performance characteristics.

[0026] One or more predefined portions of the sports equipment may be determined using a torsion map, a wear map, and / or a pressure map. The inventors have found that using this approach, components can be applied to defined areas where they are most needed. These predefined areas or defined regions may be described, for example, as "highest approximate wear zones". The application of the deposit is adapted to each map by adapting the physical properties and in particular the thickness of the liquefied polymer and / or components based on the zones derived from the maps. These zones are characterized, for example, by high pressure, traction, and / or wear. The liquefied polymer may be applied to the predefined areas with different thicknesses and weights to meet the wear and traction requirements. Furthermore, in this way, the weight, performance, life and / or durability of the sports equipment are increased.

[0027] In some embodiments, the liquefied component may be deposited on the second component according to a pattern. The advantageous effect of this method is the application of the liquefied component which is individualized and adapted, requiring less material and therefore cost-effective. Furthermore, the liquefied component may give a glossy and / or shiny appearance. The pattern may comprise a laminated and / or linear pattern. In this way, the method may be applied both to linear forms and designs, as well as to large uniform laminated designs. This has the advantageous effect of forming islands with larger or smaller amounts of the liquefied component, adapted to the individual requirements of the product and / or the consumer.

[0028] The first component may be deposited on the second component with a thickness of 1-10 mm, preferably 2-4 mm, most preferably 3 mm. The inventors have found that applying a component with a specific thickness enhances the performance of the sports equipment and achieves comparable or even enhanced results for its durability properties compared to commercially available components.

[0029] The thickness of the first component after the curing step may be 0.3 mm to 0.7 mm, preferably 0.5 mm. A particular thickness of the component has the advantage that the component exhibits comparable or better performance and / or durability properties while having a reduced weight and thickness.

[0030] In some embodiments, the deposition step can be performed by at least one of the following methods: brushing, coating, dipping, painting, automated dispensing, automated printing, controlled dispensing. The inventors have found that these particular deposition processes represent the best mode for the deposition of the liquefied polymer. The choice of deposition process depends on the properties of the liquefied polymer and the second component of the sporting goods.

[0031] In some embodiments, the second component may be manufactured by 3D printing. Preferably, the second component may be the midsole and / or shoe upper and / or parts thereof. The liquefied polymer may then be applied to the second component. The liquefied polymer may preferably be the outsole. 3D printing includes additive manufacturing methods such as stereolithography and laser sintering. In stereolithography, light crosslinks chemical monomers and oligomers to each other to form the layered polymers that make up the 3D print. In laser sintering, a laser sinters powdered materials with heat. A laser hits points in space defined by a 3D model to bond the materials together to create a solid structure. Another example of additive manufacturing is fused deposition modeling, where parts are manufactured by extruding small beads or streams of material that instantly harden to form layers. If both the midsole and the upper are manufactured using a 3D printing process, the midsole and the upper may be manufactured in separate 3D printing processes and then connected later, for example, by gluing, welding, sewing, etc. Alternatively, the midsole and upper may be manufactured together in a single manufacturing step.

[0032] In another embodiment, the second component is a midsole made of a polymeric material, and a liquefied polymer is applied to the midsole to form the outsole. In this embodiment, the polymeric material can be ethylene vinyl acetate (EVA), thermoplastic urethane (TPU), or supercritical foam. These materials provide good cushioning while being relatively lightweight.

[0033] In some embodiments, the liquefied polymer can be deposited on the first part of the sports equipment with a dynamic viscosity of 30000-50000 mPa·s and on the second part of the sports equipment with a dynamic viscosity of 10000-30000 mPa·s. Different viscosities can be obtained by varying the mixing ratio of the solvent and the polymer. In this way, it is possible to deposit different viscous materials on the second component by using one operating step. The method allows a flexible adaptation of the operating steps based on the needs of the product.

[0034] The first part can be an outer rim of a second part of the sporting goods. This feature allows for quick and easy deposition of the second component using only one operating step for deposition of one pattern on the sporting goods.

[0035] In some embodiments, the contact angle θ between the liquefied polymer and the second component is between 30° and 110°, preferably between 40° and 90°, and more preferably between 50° and 70°. The inventors have found that these wetting characteristics represent the best mode for deposition of the liquefied polymer onto the second component.

[0036] The curing step may be performed using radiation, such that the liquefied component deposited on the second component is cured on the second component while simultaneously removing the solvent and drying the deposited liquefied component.

[0037] In some embodiments, the polymer may be selected from the group of polyurethane (PU), thermoplastic polyamide (TPE-A or TPA), thermoplastic polyester (TPE-E or TPE), thermoplastic styrenic block copolymer (TPE-S or TPS), thermoplastic polyurethane (TPE-U or TPU), thermoplastic vulcanizate (TPE-V or TPV), rubber or ethylene vinyl copolymer (EVA), preferably thermoplastic polyurethane (TPE-U or TPU) and / or combinations thereof. The inventors have found that the use of these polymers allows for a highly time-efficient and sustainable process in the manufacture of components. A suitable polymer material may be a thermoplastic elastomer and / or an elastic foam material such as an elastomer. A preferred material used in the present disclosure is a thermoplastic elastomer. A more preferred material used in the present disclosure is a urethane-based thermoplastic elastomer (TPU), a polyester-based thermoplastic elastomer (TPE) and / or a polyamide-based thermoplastic elastomer (TPA).

[0038] In some embodiments, the solvent is from the group of solvent-based and / or water-based solvents, preferably from the group of solvent-based solvents, more preferably from the group of (C1-C6) ethers, (C1-C 10 ) esters, (C1-C8) ketones, (C1-C8) alkanes and / or combinations thereof. These solvents have shown the best compatibility with the manufacturing methods of the components while allowing for flexible matching of the physical properties of the polymer to the product and process requirements.

[0039] The solvent may be one or more of tetrahydrofuran (THF), methyl ethyl ketone (MEK), cyclohexane (CYC), ethyl acetate, butyl acetate, preferably a mixture of THF and / or CYC. These solvents have the advantageous effect of being removable in a time-efficient manner during the curing process, allowing for a manufacturing process that can accommodate the various physical properties of the liquid polymers.

[0040] The mixture ratio may range from 10-90% by volume, preferably 20-80% by volume, more preferably 30-70% by volume. In some embodiments, the mixture ratio may range from 10-90% by weight, preferably 20-80% by weight, more preferably 30-70% by weight. The inventors have found that this mixture ratio of solvents offers the best compatibility for both blending the polymer and changing / adapting the physical properties of the liquefied polymer to the specific requirements of the product and process.

[0041] In some embodiments, the liquefying component may have a kinematic viscosity of 10,000 to 50,000 mPa·s, preferably 20,000 to 40,000 mPa·s. The use of a liquid polymer with a particular kinematic viscosity allows for its use in automated and / or manual deposition processes.

[0042] The polymers may be characterized by their Shore A and / or Shore D values. The Shore A values ​​are in the range of 20-120, preferably 40-100, more preferably 60-80, and the Shore D values ​​are in the range of 2-80, preferably 5-75, more preferably 8-70. The use of polymers with these Shore A and / or Shore D values ​​provides for the durability properties of the final component. Suitable polymer materials are elastic foam materials such as thermoplastic elastomers (TPEs) and / or elastomers.

[0043] The polymer to solvent ratio in the mixing step may range from 2:98 to 40:60 vol.%, preferably 5:95 to 30:70 vol.%, more preferably 10:90 to 20:80 vol.%. The inventors have found that certain ratios of solvent to polymer allow for convenient use in the deposition process and flexible adaptation to product and / or process requirements.

[0044] In some embodiments, the liquefied polymer may further include dyes and / or fibers, which allows for increased stiffness and durability in selected areas of application. "Fiber" is understood to mean, but is not limited to, threads or filaments based on natural and / or synthetic materials.

[0045] The liquefied polymer may further comprise granules. In this way, traction and grip properties are enhanced in selected areas of the sports equipment based on the use of granules. "Granules" are understood as particles of various sizes and shapes that may have specific physical properties based on, but are not limited to, natural and / or synthetic materials.

[0046] In some embodiments, the curing step may have a curing temperature of 20° C. to 150° C., preferably 30° C. to 100° C., more preferably 40° C. to 50° C., and a curing time of 2 minutes to 750 minutes, preferably 5 minutes to 390 minutes, more preferably 10 minutes to 30 minutes. The inventors have found that these curing conditions allow for a cost and energy efficient process for the manufacture of components.

[0047] In a further aspect, the present invention relates to a method for manufacturing a sports shoe, comprising the method of the present disclosure, wherein the first component is an outsole of the sports shoe and the second component is a midsole of the sports shoe. An advantageous effect of the method for manufacturing a sports shoe is, for example, to avoid the adhesion of the outsole to the midsole of the sports shoe and the deposition based on injection molding.

[0048] In another aspect, the present invention relates to an outsole manufactured by the method of the present disclosure. The inventors have found that the components can be specifically used to create lighter and thinner outsoles while allowing for comparable and / or even enhanced performance and durability of the components. The outsole can have a pattern. In this way, the outsole can be individually designed based on the needs and requirements of the product and / or the consumer.

[0049] In a further aspect, the present invention relates to an athletic shoe comprising an outsole according to the present disclosure. The inventors have found that an athletic shoe comprising an outsole according to the present disclosure is lighter and thinner, making the overall athletic shoe more desirable. Furthermore, the athletic shoe exhibits durability and performance characteristics comparable to and / or improved over athletic shoes known in the art.

[0050] The outsole may be located at least in the toe, midfoot and / or heel portions of the sneaker, which has the advantage that the outsole can be located in specific portions of the sneaker, allowing for weight reduction and material and cost savings.

[0051] In another aspect, the present invention relates to an athletic shoe comprising a first component and a second component, the first component being manufactured by the method of the present disclosure, the first component being disposed relative to an upper of the athletic shoe. The inventors have found that an athletic shoe comprising components according to the present disclosure exhibits durability and performance characteristics comparable to and / or enhanced over athletic shoes known in the art, while making the overall athletic shoe more desirable.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0054] Possible embodiments and variants of the invention are described below with particular reference to sports goods, in particular athletic shoes, although the inventive concept is not limited to these embodiments, and the methods described herein may be applied identically or similarly to the manufacture of any sports goods in general, such as, for example, sports clothing or sports equipment.

[0055] It should be noted that individual embodiments of the present invention are described in more detail below. However, it is clear to those skilled in the art that the configuration possibilities and optional features described in relation to these specific embodiments can be further modified and combined with each other in different ways within the scope of the present invention, and that individual steps or features can also be omitted if they are deemed unnecessary by those skilled in the art. To avoid redundancy, reference is made to the descriptions in the previous parts, which also apply to the embodiments in the detailed description below.

[0056] FIG. 1 shows a flow diagram illustrating exemplary method steps for a method 100 of manufacturing a component 240 according to the invention, preferably for a sporting goods 260. The method 100 starts with a method step 110 of providing a polymer. The polymer is selected from the group of elastomers and / or thermoplastic elastomers. Suitable materials from the group of elastomers are block foams such as ethylene vinyl acetate (EVA), polyurethane (PU) and / or rubber. Thermoplastic elastomers (TPEs) are crosslinked and / or non-crosslinked bead block foams and are classified using the following groups: TPE-O or TPO; TPE-V or TPV; TPE-U or TPU; TPE-E or TPE or TPC; TPE-S or TPS; TPE-A or TPA. Polymer materials from the group of TPE-O or TPO are polypropylene (PP), ethylene propylene diene rubber or ethylene propylene diene monomer rubber (EPDM). Suitable polymeric materials from the group TPE-V or TPV are thermoplastic vulcanizates such as Sarlink®. Suitable polymeric materials from the group TPE-U or TPU are further classified into ester-based, ether-based or linear UP materials. For example, a suitable ester-based TPU material is, for example, Huntsman-H Foam®. For example, a suitable ether-based TPU material is, for example, Elastollan® 11XX (BASF). Suitable polymeric materials from the group TPE-E or TPC are, for example, Hytrel® (DuPont), Keyflex® (LG) and / or Arnitel® (DSM). Suitable polymeric materials from the group TPE-S or TPS are, for example, Styroflex® (BASF). Suitable polymeric materials from the group TPE-A or TPA are from the group of polyether block amides such as PEBAX® and / or Vestamid®. The polymer in method step 110 is characterized by having a Shore A and / or D value, the Shore A value being in the range of 20-120, preferably 40-100, more preferably 60-80, and the Shore D value being in the range of 2-80, preferably 5-75, more preferably 8-70.

[0057] The second step in the method 100 is method step 120 of providing a solvent. Suitable solvents are from the group of solvent-based and / or water-based solvents, preferably from the group of solvent-based solvents, more preferably from the group of (C1-C6) ethers, (C1-C 10 The solvent is preferably a mixture of one or more of tetrahydrofuran (THF), methyl ethyl ketone (MEK), cyclohexane (CYC), ethyl acetate, butyl acetate, preferably THF and / or CYC. The ratio of the mixture of solvents is in the range of 10-90% by volume, preferably 20-80% by volume, more preferably 30-70% by volume.

[0058] In a third method step 130 in the method 100, the polymer and the solvent are mixed, thereby producing a liquefied polymer 230. The ratio of polymer to solvent in the mixing step is in the range of 2:98 to 40:60% by volume, preferably 5:95 to 30:70% by volume, more preferably 10:90 to 20:80% by volume. The ratio of polymer to solvent in the mixing step is in the range of 10 to 90% by weight, preferably 20 to 80% by weight, more preferably 30 to 70% by weight.

[0059] As shown in FIG. 1, the method 100 may comprise optional method steps 150 and 160. These steps precede a curing step 170. In method step 150, a liquefied polymer 230 is deposited on the second component 250. The liquefied component 230 is deposited on the second component 250 to a thickness of 1-10 mm, preferably 2-4 mm, most preferably 3 mm. Still further, the liquefied component 230 is deposited on one or more portions of the athletic shoe. These portions include a toe portion, a forefoot portion, a heel portion, a midsole portion, a sidewall portion, and / or an upper portion. In particular, the liquefied component 230 is deposited on a predetermined portion determined using a torsion map, a wear map, and / or a pressure map, as described in more detail below. The liquefied polymer is deposited in a deposition step 150, which may be performed by at least one of the following methods: brushing, coating, dipping, painting, automated dispensing, automated printing, controlled dispensing. The second component 250 is preferably deposited by automated printing, the second component being the midsole and / or the shoe upper or parts thereof, preferably both. The deposition of the second component as the shoe upper and / or the midsole is carried out in one process step, preferably by 3D printing. The liquefied polymer is then applied to the second component. The liquefied polymer is the outsole 290. A preferred deposition step is carried out by an automated process. The liquefied component 230 for deposition has a dynamic viscosity of 10000-50000 mPa·s, preferably 20000-40000 mPa·s.

[0060] In particular, to accelerate the deposition process, the outer rim of the area of ​​the sports equipment targeted during the deposition step is dispensed with a thinner nozzle and a higher viscosity liquefied polymer to form a more robust rim. Secondly, the inner area of ​​the rim is dispensed in a quicker process with a wider nozzle and a lower viscosity liquefied polymer. Thus, the liquefied polymer is dispensed with a kinetic viscosity of 30000-50000 mPa·s on a first portion of the sports equipment and with a kinetic viscosity of 10000-30000 mPa·s on a second portion of the sports equipment. The second portion is the area positioned between the first regions. The first portion is the outer rim of the second portion of the sports equipment 260.

[0061] In some embodiments, during deposition, the contact angle θ between the liquefied polymer 230 and the second component 250 is between 30° and 110°, preferably between 40° and 90°, more preferably between 50° and 70°. A suitable deposition is an automated deposition process. In some embodiments, the liquefied polymer comprises granules. Furthermore, it may further comprise dyes and / or fibers. In some embodiments, the liquefied component 230 is deposited on the second component 250 according to a pattern, for example as illustrated in Figures 2 and 4. The pattern comprises a laminated and / or linear pattern.

[0062] After deposition, the liquefied polymer 230 may be textured during optional method step 160. Adding texture to the deposited liquefied polymer 230 may be performed using texturing devices known in the art, such as pattern brushes and / or pattern rollers. Adding texture and structure may also be performed by pressing a pattern into the deposited semi-dry liquefied polymer 230 with a pattern device.

[0063] In the last method step 170 of the method 100, the liquefied polymer is cured. Thus, in some embodiments, the liquefied polymer 230, which may be deposited on the second component 250, is cured while at the same time the solvent present in the liquefied polymer 230 is removed. The solvent may be removed by condensation and the condensate may be reused. The curing temperature in the curing step 170 is between 20°C and 150°C, preferably between 30°C and 100°C, more preferably between 40°C and 50°C, and the curing time is between 2 minutes and 750 minutes, preferably between 5 minutes and 390 minutes, more preferably between 10 minutes and 30 minutes. In some embodiments, the curing step 170 is performed using radiation. The curing 170 is preferably performed using infrared radiation (IR). However, other types of radiation are also applicable. The thickness of the component 240 after the curing step is between 0.3 mm and 0.7 mm, preferably 0.5 mm.

[0064] In some embodiments, the sports article 260 obtained in part by the method 100 shown in FIG. 1 is a sports shoe 260. In particular, the component 240 is a sole, preferably an outsole, of the sports shoe. Furthermore, the sports shoe obtained in part by the method 100 is a football shoe. In this context, the component is a stud of the sports shoe. The sports shoe 260 may comprise at least two components, a first component and a second component. The first component is an outsole 290 produced by the method 100 shown in and described with respect to FIG. 1. The second component is a midsole 350 of the sports shoe 260.

[0065] The sports equipment 260 illustrated in Fig. 2 is an athletic shoe 260. Fig. 2 shows an exemplary outsole of the athletic shoe 260 manufactured by the method according to the present invention according to certain aspects of the present disclosure. For a better understanding of the present invention, three different views of the athletic shoe 260 are shown, namely two side views (left and right views) and one view from below (middle view). In Fig. 2, the component 240 is the outsole 290 of the sports equipment 260. The component 240, i.e. the outsole 290 of the shoe, is manufactured by the method 100 described with respect to Fig. 1.

[0066] Returning to FIG. 2, the liquefied polymer 230 is deposited following a continuous dispensing path to the second component 250. In this way, the outsole 290 has a linear configuration. The liquefied polymer 230 is deposited on the second component 250, which in FIG. 2 is not directly connected to the shoe upper. It is also conceivable that the second component 250 on which the liquefied polymer 230 is deposited is directly connected to the shoe upper. A pattern like that of FIG. 2 is obtained by using a thin nozzle during the deposition of the liquefied polymer 230, which follows the path indicated by the black line. In this way, the outsole 290 has a pattern 300, as can be seen in FIG. 2, with no liquefied polymer in the white areas. The second component 250 is therefore clearly represented by the outsole 290.

[0067] In FIG. 2, the outsole 290 has a different material than the midsole. However, it is also conceivable that the midsole and the outsole have the same material and / or shape. In some embodiments, the midsole and the shoe upper are manufactured by the above method. In this way, the entire athletic shoe 260 is manufactured by the method according to the present invention. In some embodiments, the outsole 290 according to the aspects of the present invention is connected to the midsole, which is manufactured in a one-step process together with the shoe upper. In this context, the deposition is performed using 3D printing.

[0068] Returning to Fig. 2, the outsole 290 has a pattern 300. As can be seen in Fig. 2, the deposited components 240 have a linear pattern. The athletic shoe 260 can be manufactured by using the above-described method of manufacturing the components 240 according to the present disclosure so that they are disposed relative to the midsole 350 of the athletic shoe 260. As can be seen in Fig. 2, the outsole 290 is disposed in the toe portion 10, the midfoot portion, and the heel portion 20 of the athletic shoe.

[0069] An exemplary embodiment of an outsole is shown in FIG. 3. As can be seen in FIG. 3, the outsole 290 has a layered pattern 300. Furthermore, the outsole 290 provides a glossy and shiny appearance. The outsole 290 in FIG. 3 has two different colors, namely, a dark color in the midfoot and forefoot portion and a light color in the heel portion. It is also conceivable that the outsole 290 has only one color or more than two colors. Furthermore, as can be seen in FIG. 3, the outsole 290 is arranged in three segments, namely, one large layered segment positioned for the midfoot and forefoot portion and two small layered segments positioned for the heel portion.

[0070] To achieve this pattern or appearance, a polymer is mixed with a solvent to obtain a liquefied polymer 230 which is uniformly deposited onto the second component 250, ie, the midsole.

[0071] The liquefied component 230 is deposited on one or more different parts of the sporting goods 260, such as the toe part, the forefoot part, the heel part, the midsole part, the sidewall part and / or the upper part. The liquefied polymer is deposited by at least one of the following methods: brushing, coating, dipping, painting, automated dispensing, automated printing, controlled dispensing. A preferred deposition mode is performed by an automated process. In some embodiments, the second component 250 is the midsole and / or the shoe upper or parts thereof, preferably both, and the second component can be manufactured by a 3D printing process. 3D printing includes additive manufacturing methods such as stereolithography and laser sintering. In stereolithography, light crosslinks chemical monomers and oligomers to each other to form layered polymers that make up the 3D print. In laser sintering, a laser sinters powdered materials with heat. A laser is aimed at points in space defined by a 3D model to bond the materials together to create a solid structure. Another example of an additive manufacturing process is fused deposition modeling, where parts are produced by extruding small beads or streams of material that instantly harden to form layers.

[0072] In a subsequent step, the liquefied polymer 230 used to manufacture the outsole 290 is applied to the 3D printed midsole and / or shoe upper. If both the midsole and upper are manufactured using a 3D printing process, the midsole and upper may be manufactured in separate 3D printing processes and then subsequently connected, for example, by gluing, welding, sewing, etc. Alternatively, the midsole and upper may be manufactured together in a single manufacturing step.

[0073] 3, the second component is a midsole made of a polymeric material, and a liquefied polymer is applied to the midsole, thereby forming the outsole 290. In this embodiment, the polymeric material can be ethylene vinyl acetate (EVA), thermoplastic urethane (TPU), or supercritical foam.

[0074] In FIG. 4, the outsole 290 has a linear pattern 300. To obtain this pattern, the liquefied polymer 230 is deposited in a continuous dispensing mode. The linear pattern is characterized by a constant width, which is achieved by using a dispenser nozzle with a constant output during deposition. In this way, the liquefied polymer 230 is dispensed without interruption of the deposition process. Preferably, the liquefied polymer 230 has physical properties that do not change throughout the deposition process. The outsole 290 is obtained by the method described with reference to FIG. 1. The component 240 has a thickness, after curing, of 0.3 mm to 0.7 mm, preferably 0.5 mm.

[0075] 3, the second component is again a midsole made of a polymeric material, and a liquefied polymer is applied to the midsole, thereby forming the outsole 290. Again, in this embodiment, the polymeric material can be ethylene vinyl acetate (EVA), thermoplastic urethane (TPU), or supercritical foam.

[0076] In figures 5 and 6, the components 240 manufactured by the method of the invention as described above are used as studs 285 for a sports shoe, which is a football shoe 275. As can be seen in figures 5 and 6, the studs 285 are arranged relative to the sole of the football shoe 275. In figure 5, the studs 285 have a different shape and appearance than the sole of the football shoe 275. In some embodiments, the studs 285 and the sole of the football shoe 275 are manufactured in several individual steps, for example in a separate manufacturing of the studs and the sole according to an aspect of the invention and a subsequent deposition of the studs 285 on the sole. In this context, the studs 285 are manufactured using a different material than the sole. In some embodiments, the material of the sole of the sports shoe 275 and the studs 285 are the same, which can be seen in more detail in figure 6. Furthermore, the studs 285 and the sole in figure 6 are manufactured in a one-step process by the method of the invention.

[0077] In some embodiments, the component 240 manufactured according to the aspects of the invention is applied to the transition zone of the sports article 260, which can be seen in more detail in FIG. 7. The component 240 is applied to two or more parts of the sports article 260. As can be seen in FIG. 7, the athletic shoe 260 comprises an outsole 290 and a midsole 350, and the component 240 is arranged on both shoe elements, i.e. on the sole 280 of the athletic shoe 260, i.e. on the midsole and outsole 290, as well as on the shoe upper. To obtain this pattern, the liquefied polymer 230 is deposited additionally on the midsole 350 and on the shoe upper. In FIG. 7, the midsole 350 and the outsole 290 have the same shape and / or material. However, in some embodiments, it is also possible that the midsole 350 and the outsole 290 have different patterns 300 and / or materials. In this context, the liquefied polymer 230 is textured after deposition. Adding texture to the deposited liquefied polymer 230 is carried out using a texturing device such as a pattern brush and / or a pattern roller.

[0078] Addition of texture and structure is further performed by pressing a pattern with a patterning device into the deposited semi-dry liquefied polymer 230. Still further, components 240 are deposited in the transition zone of the outsole 290 and particularly in the heel segment 20 of the outsole 290. Using this approach, components 240 can thus be arranged to form a pattern 300 in two or more portions of the sporting article 260.

[0079] As discussed in the introduction to this disclosure, the liquefied component can be deposited on predetermined portions of the sporting article 260 using the torsion, wear and / or pressure maps shown in Figures 8-11. In this manner, the liquefied polymer 230 is applied to areas where the greatest wear, traction or torsion is measured.

[0080] In FIG. 8, a given zone of the sole 280 according to an embodiment of the present invention is measured using a wear map. Preferably, the wear map is used to determine the zone of the outsole 290 to which the liquefied polymer is applied as described herein. In this manner, the liquefied polymer 230 is applied, for example, to the sidewall, toe cap 10, and heel counter 20. The midfoot region 15 may be omitted from the liquefied polymer 230. However, in some embodiments, the liquefied polymer 230 is also applied to the midfoot region 15. Using this approach, the liquefied polymer 230 can be applied with different physical properties, such as thickness, weight, color, and / or viscosity, to given regions. In this manner, each measured region with its special needs can be individually addressed during the deposition of the liquefied polymer 230 on the second component 250 (e.g., midsole, upper, etc.). This approach can be used, for example, to increase the durability of a sporting goods based on different traction, wear, and / or pressure applied thereto during its use. In some embodiments, the liquefied polymer 230 is deposited using a mask. In this manner, the liquefied polymer 230 is deposited on the sporting goods in desired zones and / or patterns.

[0081] It should be noted that the wear, traction and / or pressure maps will vary based on the sporting goods and even based on the type of sport (e.g., basketball, football, tennis, etc.) for which the sporting goods may be used. For example, the sole, and preferably the outsole, of a basketball shoe is reinforced by applying component 240 to one or more areas where the greatest lateral traction is recorded. Similarly, component 240 is preferably applied to the sidewall areas of the sole of a tennis shoe to support those areas that exhibit the greatest traction and / or wear.

[0082] Now, in FIG. 9, two maps are shown for an outsole 290 according to an embodiment of the present invention with predefined zones. These predefined zones are determined / measured using a traction map, a wear map and / or a pressure map. In the first map (top), the outsole 290 comprises a thicker layer of components 240, especially in the "mid-to-forefoot" heel zone. The thickness of the components 240 located at the rim compared to the components 240 located in the central region may vary. Furthermore, the adjacent regions exactly surrounding these thicker regions may also comprise components 240 in layers of different thicknesses. The rims bordering both the "thickest" and "adjacent" regions may further vary, i.e. comprise components 240 of different thicknesses. The remaining regions may comprise a thinner layer of components 240 or no layers of components 240.

[0083] In the second map (bottom row), the outsole 290 comprises thicker layers of components 240, especially in the "heel to sidewall" and "midfoot to sidewall" zones. As in the top map, the thickness of the rim and central regions of the deposited components 240 may vary. Furthermore, adjacent regions surrounding these thicker regions may also comprise components 240 in layers of different thicknesses. The rims bordering both the "thickest" and "adjacent" regions may further comprise components 240 of different thicknesses. The remaining regions may comprise thinner layers of components 240 or no layers of components 240. As a result, the components 240 reduce the overall weight of the outsole and the sports equipment while at the same time increasing the durability of the sports equipment.

[0084] 10 shows an example traction map for determining predetermined zones of an outsole 290 according to an embodiment of the present invention. Using this approach, the component 240, and in particular the liquefied polymer 230, is applied to the second component 250 at different thicknesses and viscosities in various zones, such as the toe cap 10, the midfoot zone 15, and / or the heel zone 20. These predetermined zones may be different from the zones that may be measured by other maps, such as a pressure map as shown in FIG.

[0085] An example pressure map that can be used to determine the predefined zones of an outsole 290 according to an embodiment of the present invention is shown in Figure 11. As can be seen in the self-explanatory Figure 11, the heel portion 20 shows an increase in pressure compared to the midfoot portion 15. This difference can be addressed by applying component 240 to these "high pressure" zones, i.e., depositing a thicker layer of liquefied polymer in these "high pressure" areas.
