本發明之額外態樣連同附屬於本發明之優點及新穎特徵將部分地在以下[實施方式]中進行闡述，且將部分地對於熟習此項者在檢驗以下內容之後變得顯而易見，或可由本發明之實踐而習得。可借助於特別是在附加申請專利範圍中指出之手段及組合來實現並達成本發明之目標及優點。
本發明係針對一種包含多重板片外罩的運動球，其中該等板片之一或多個邊在不必縫合之情況下結合在一起，且在板片邊界處藉由位於該等板片之內部表面上的加強材料予以加強。外罩包含一已熱結合至加強材料坯料之外罩板片坯料。
現參看圖1至圖11，說明根據本發明之較佳實施例的諸如足球之運動球10。如圖1A及圖1B中所展示，運動球10包含一充氣囊20，該充氣囊20具有一習知氣閥25。運動球10亦包含一經加強之外罩30，該經加強之外罩30由已熱結合在一起之一或多個外罩板片坯料35及一或多個加強材料坯料65形成。外罩板片坯料35在其上具有板片圖案，例如，根據典型足球圖案之包含十二個五邊形板片及二十個六邊形板片的板片圖案。板片圖案藉由內部板片邊界43界定，且加強材料僅沿內部板片邊界定位，以便模擬習知接縫。如熟習此項技術者所知曉，一或多個可選中間層(未圖示)可駐留於經加強之外罩30與囊20之間。
充氣囊20通常由任一可撓材料製成。例示性材料包括丁基橡膠、天然橡膠、丁基橡膠與天然橡膠之組合、乳膠及其他彈性材料。在尤其較佳實施例中，囊20由80%丁基橡膠及20%天然橡膠製成。充氣囊經調適以經由氣閥25充飽氣以在經加強之外罩30內形成實質上球形形狀。
經加強之外罩30包含已熱結合在一起之一或多個外罩板片坯料35及一或多個加強材料坯料65。如本文中所利用，術語「熱結合」或其變體被定義為兩個元件之間的涉及元件中之至少一者的熔融或軟化使得元件之材料在冷卻時緊固至彼此的緊固技術。一般而言，熱結合可涉及外罩材料及加強材料之熔融或軟化，使得該等材料在冷卻時緊固在一起。因此，熱結合通常並不涉及使用縫合或黏著劑。而是，兩個元件藉由熱直接結合至彼此。然而，在一些情形下，縫合或黏著劑可用以補充元件之經由熱結合的接合。
在例示性態樣中，經加強之外罩30包含由外罩材料製成之兩個或兩個以上外罩板片坯料。外罩板片坯料由板片片材形成，該板片片材包含具有如下文更詳細論述之板片圖案之連續外罩材料片材。將加強材料應用至外罩板片坯料以便有助於將外罩板片坯料熱結合在一起。
外罩材料32較佳包含通常係耐用且耐磨之以下各者中的一或多者：合成皮革、熱塑性胺基甲酸酯、聚胺基甲酸酯、聚氯乙烯、熱塑性彈性體、橡膠、各種其他熱塑性或熱固性材料或其他合適材料，不管為合成的抑或天然的。在一些組態中，外罩材料可具有一組合兩種或兩種以上材料之層化組態，該等材料通常被共擠出。舉例而言，外罩材料之外部部分可由聚胺基甲酸酯或聚氯乙烯形成，且外罩材料之內部部分可由紡織品元件(例如，編織物或不織物)形成。亦即，充當襯底或支撐件之紡織品元件可結合至聚胺基甲酸酯或聚氯乙烯，且接近囊而定位。外罩材料通常具有在約0.5mm至4mm(例如，約0.5、1.0、1.5、2.0、2.5、3.0、3.5或4.0mm)之範圍中的厚度。
在較佳實施例中，具有板片圖案40之板片片材37係使用流動模製裝置由外罩材料形成。一般而言，如圖2中所展示，例示性流動模製裝置110包括第一電極112及第二電極114，其兩者連接至一可操作以在電極之間產生交流射頻電場的電磁能量源(未圖示)。交流射頻電場可以在1MHz至500MHz之範圍中的頻率產生，較佳以在10MHz至200MHz之範圍中的頻率產生，且最佳以27.12MHz或40.68 MHz產生。通常，施加能量歷時約10至30秒(例如，約10、15、20、25或30秒)。第一模具116及第二模具118亦包括於裝置內，第一模具116及第二模具118一起在其之間界定板片片材模穴120。將外罩材料32置放於板片片材模穴120內，以便將外罩材料32模製成板片片材37。
在圖3A、圖3B及圖4中說明已使用圖2之模製裝置模製的例示性板片片材37。在一較佳態樣中，板片片材37之總體組態使得其為大體上平坦的。亦即，如圖4中所展示，多邊形(例如，六邊形及五邊形板片)中之每一者的頂點大體上位於同一平面內。然而，板片片材37之板片圖案40內之板片中的每一者在三個維度上彎曲，以遵循最終球10之曲率半徑。板片圖案內之板片由複數個內部板片邊界43來劃定界限。
應瞭解，第一模具116具有：複數個圖案化之板片凹座117a，其用於形成板片片材中之板片圖案40中之板片的頂面；及複數個突起117b，其用於形成內部板片邊界43。同樣，第二模具118具有：複數個板片突起119a，其用於形成板片圖案40中之板片的底面；及凹座119b，其用於形成內部板片邊界43。凹座及突起之組態及圖案將視最終遊戲球中所要之板片圖案而定。舉例而言，在一較佳態樣中，第一模具116的圖案化之板片凹座117a及突起117b將能夠形成圖3A中所展示之板片片材37的頂部。同樣，第二模具118的板片突起119a及凹座119b將能夠形成圖3B中所展示之板片片材37的底部。
板片片材37亦可經模製，使得其包括各種構形或表面特徵，例如，肋狀物、溝道、桿、圖形、標誌及其類似者。另外，表面特徵可包括表面上之鵝卵石或波紋紋理(類似於在習知籃球中見到的紋理)。雖然可在模製製程期間形成此等構形或表面特徵，但應瞭解，此等特徵可在模製之後(例如)藉由用雷射進行蝕刻或藉由合適機械器件進行軋花來施加。
在例示性板片片材37中，板片片材37中之板片圖案40包含複數個多邊形板片42，其藉由統稱為「內部板片邊界」43之各種凹陷、溝道或溝槽、突起或隆脊(視自頂部(例如，圖3A)抑或底部(例如，圖3B)觀察而定)來劃定界限。內部板片邊界較佳具有模擬足球上之習知手縫接縫的尺寸。通常，邊界43寬度為約2 mm至6 mm(例如，寬度為約2.0、2.2、2.4、2.6、2.8、3.0、3.2、3.4、3.6、3.8、4.0、4.2、4.4、4.6、4.8、5.0、5.2、5.4、5.6、5.8或6.0 mm，寬度較佳為約3.2至4.0 mm，且寬度更佳為3.6 mm)，且具有約1.0至2.0 mm之深度(例如，約1.0、1.2、1.4、1.6、1.8或2.0 mm深，且較佳約1.8 mm深)。
在圖3A及圖3B中展示例示性板片圖案40。此板片圖案40對應於足球之一半球形部分的圖案。板片圖案40包含六個五邊形板片44a、44b、44c、44d、44e、44f，及十個六邊形板片46a、46b、46c、46d、46e、46f、46g、46h、46i、46j。中心五邊形板片44a之每一邊鄰近於五個內部六邊形板片46a、46b、46c、46d、46e之第一邊。五個內部六邊形板片46a、46b、46c、46d、46e之每一者之第二邊鄰近於五個鄰近外部六邊形板片46f、46g、46h、46i、46j的第一邊。五個內部六邊形板片46a、46b、46c、46d、46e中之每一者的第三邊亦鄰近於五個外部五邊形板片44b、44c、44d、44e、44f的第一邊。
熟習此項技術者應瞭解，板片片材37中之板片圖案40可具有各種形式。舉例而言，雖然例示性板片圖案40被描繪為具有等邊五邊形及六邊形之形狀，但板片可具有非等邊形狀。板片圖案可包括以鑲嵌類型方式組合以形成外罩的多種其他形狀(例如，三角形、正方形、矩形、五邊形、六邊形、梯形、圓形、橢圓形)，且板片圖案亦可包括不規則或非幾何形狀。
在形成板片片材37之後，板片片材37經切割以形成外罩板片坯料35。外罩板片坯料包括板片圖案40。過量外罩材料32經移除以便在外罩板片坯料之周邊周圍提供自由邊緣，同時板片圖案40由自由邊緣與內部板片邊界之組合保持。較佳藉由刀模切割來移除過量外罩材料32。
圖5說明由圖3A、圖3B及圖4之板片片材37形成之例示性外罩板片坯料35。中心五邊形板片44a藉由內部板片邊界43而與五個內部六邊形板片46a、46b、46c、46d、46e劃定界限。中心五邊形板片44a不含自由邊緣48。五個內部六邊形板片46a、46b、46c、46d、46e藉由內部板片邊界43而與中心五邊形板片44a，五個外部六邊形板片46f、46g、46h、46i、46j及五個外部五邊形板片44b、44c、44d、44e、44f劃定界限。每一內部六邊形板片46a、46b、46c、46d、46e含有三個自由邊緣48。每一外部六邊形板片46f、46g、46h、46i、46j具有五個自由邊緣48，且每一外部五邊形板片44b、44c、44d、44e、44f具有四個自由邊緣48。多邊形板片在其由單一外罩材料片材形成之範圍內經整體連接，但如上文所論述藉由內部板片邊界來劃定界限。
如下文更充分論述，在此例示性實施例中，外罩板片坯料之自由邊緣48熱結合在一起以形成半球形外罩部分50，且亦沿自由邊緣48及內部板片邊界43熱結合至加強材料坯料65。
加強材料坯料65包含加強材料60。加強材料60較佳包含大體上係耐用且耐磨之以下各項中的一或多者：合成皮革、熱塑性胺基甲酸酯、聚胺基甲酸酯、聚氯乙烯、熱塑性彈性體、橡膠、各種其他熱塑性或熱固性材料或其他合適材料，不管為合成的抑或天然的。在一些組態中，外罩材料可具有一組合兩種或兩種以上材料之層化組態，該等材料通常被共擠出。舉例而言，外罩材料之外部部分可由聚胺基甲酸酯或聚氯乙烯形成，且外罩材料之內部部分可由紡織品元件(例如，編織物或不織物)形成。亦即，充當襯底或支撐件之紡織品元件可結合至聚胺基甲酸酯或聚氯乙烯，且接近囊而定位。加強材料60可與外罩材料32相同或不同。加強材料之厚度為約0.5mm至4mm(例如，約0.5、1.0、1.5、2.0、2.5、3.0、3.5或4.0mm)。
外罩材料及加強材料以及每一者之厚度的選擇較佳地係被選擇而使得每一者以及囊之組合重量遵守適用之運動法規(例如，在足球之狀況下，國際足球聯合會)。
加強材料坯料65經組態並塑形，使得其可與外罩板片坯料35之自由邊緣48對準，且較佳亦與內部板片邊界43對準，以形成經加強之球外罩或外罩部分。通常藉由將合適材料刀模切割成所要組態來製備加強材料坯料65。
在圖6中說明例示性加強材料坯料65。加強材料坯料65包含複數個經鏈接之多邊形外形70，其中多邊形外形之每一頂點72含有一自該頂點72延伸的輻射臂74。來自每一多邊形外形之輻射臂74中的一者具有Y狀末端76，而來自每一多邊形外形之四個其他輻射臂74為大體上線性且長度為等距的。通常，加強材料坯料之寬度為約6至25mm(例如，約6、7、8、9、10、11、12、13、14、15、16、17、18、19、20、21、22、23、24或25mm寬，且較佳為約10至18mm寬，且最佳為約14mm寬)。寬度經設計以遵循習知手縫接縫的寬度。在一些實施例中，加強材料坯料之寬度稍寬於習知手縫接縫，以便改良球之總體效能。
將易於瞭解，加強材料坯料65之組態可包含複數個加強材料坯料部分而非如圖6中所說明的單一加強材料坯料。舉例而言，圖6中所說明之五個五邊形外形中的每一者可為分離之加強材料坯料部分。另外，每一五邊形之數個區段可經分離地製造(例如，加強材料坯料部分可為五邊形的兩個邊)。包含單件加強材料(與數個區段相對)之加強材料坯料65為較佳的，此係因為此情形減少了與運動球之製備相關聯的時間。
另外，應瞭解，加強材料坯料65之組態將視外罩板片坯料35中之板片圖案40而變化。因此，視外罩板片坯料中之板片圖案40的性質而定，加強材料坯料可包括三角形、正方形、矩形、五邊形、六邊形、梯形、圓形或甚至橢圓形外形。
在形成外罩板片坯料35及加強材料坯料65之後，接著將兩者熱結合在一起以形成遊戲球之外罩或外罩部分。在較佳實施例中，使用流動模製裝置(例如，使用介電加熱)將材料熱結合在一起。在圖7至圖8中說明例示性流動模製裝置200。一般而言，流動模製裝置包括一頂部電極212及一底部電極214，其兩者連接至一可操作以在電極之間產生交流射頻電場的電磁能量源(未圖示)。如大體上在以引用之方式併入之Marc的美國專利第4,268,238號中所論述，電極212、214形狀較佳為球形，使得球之半球將被均勻加熱。
第一模具及第二模具亦包括於裝置內。如圖7B中所展示，第一模具包含一母球外罩模具216且第二模具涵蓋公球外罩模具218，母球外罩模具216及公球外罩模具218一起在其之間界定模穴220。母球外罩模具216形狀為半球形，且含有用於容納外罩板片坯料35中之板片圖案40中之相應板片的複數個圖案化之板片凹座217a，及待與內部板片邊界43及自由邊緣48對準的突起217b。同樣，公球外罩模具218含有待與外罩板片坯料35之板片圖案40中之相應板片對準的複數個板片突起219a，及用於容納加強材料坯料65之凹座219b，加強材料坯料65與外罩板片坯料35之內部板片邊界43及自由邊緣48對準。母球外罩模具216及公球外罩模具218經對準，使得加強材料坯料65與外罩板片坯料35之自由邊緣48對準，且較佳亦與內部板片邊界43對準。
對於熱結合而言，交流電場可以在1 MHz至500 MHz的範圍中之頻率產生，較佳以在10 MHz至200 MHz的範圍中之頻率產生，且最佳以27.12 MHz或40.68 MHz產生。通常施加能量歷時約10至80秒(例如，約10、20、30、40、50、60、70或80秒)。加強材料坯料65因此熱結合至外罩板片坯料35，使得加強材料沿外罩板片坯料35之自由邊緣之全部或部分定位(該等自由邊緣經熱結合且因此在熱結合之後不再為「自由的」)，且較佳沿內部板片邊界48定位。因此形成球外罩之第一半球形外罩部分50，其大體上展示於圖8A及圖8B中。可以類似樣式製成球外罩之第二半球形外罩部分52(因此將圖8A及圖8B標記為半球形外罩部分50、52)。
為了組裝運動球，將經加強之球外罩30的第一半球形外罩部分50及第二半球形外罩部分52熱結合在一起。在一較佳態樣中，球外罩之第一半球形外罩部分50及第二半球形外罩部分52僅在半球形外罩部分中之每一者的重疊區域處熱結合在一起。兩個半球形外罩部分50、52中之一者在板片中之一者中(例如，在中心五邊形板片44a中)亦具有一刀模切割孔洞55從而定位囊閥25。
圖9A至圖9D說明用於將球外罩之半球形外罩部分50、52熱結合在一起的第一例示性模製裝置300。模製裝置含有第一屏蔽罩312及第二屏蔽罩314，其兩者屏蔽來自一可操作以產生微波熱量之源的電磁能量且用以將微波能量捕集於裝置內。通常，施加能量歷時約1至3分鐘。微波能量較佳經由波導305產生，該波導305居中在兩個半球形外罩部分50、52之重疊區段之間且具有約為重疊區段之大小的寬度。重疊區段較佳定位於微波能量之正弦波之波峰處，使得微波能量之大部分侷限於兩個半球形外罩部分的重疊區段上。第一模具316及第二模具318亦包括於裝置內，第一模具316及第二模具318一起在其之間界定模穴。第一模具316及第二模具318各自容納經加強之球外罩30的半球形外罩部分50、52中之一者。因此，模具較佳含有用於容納外罩中之板片的板片凹座及用於容納內部板片邊界的突起。圖9A、圖9B及圖9C說明囊20，其具有一連接至配管27的氣閥25。配管27插入至半球形外罩部分中之一者中的孔洞55中，且亦穿過第一模具316及屏蔽罩312中的孔洞310(圖9C)。配管27連接至一能夠按需要將囊20充氣或放氣之壓力調節器(未圖示)。使模具閉合，且接著較佳經由位於配管27之末端處的針使囊20充氣(通常在0.6巴(bar)至0.8巴(bar)之間)。使用微波能量將經加強之球外罩30的第一半球形外罩部分50及第二半球形外罩部分52熱結合在一起，同時使球外罩旋轉較佳至少360度，以便在兩個半球形部分50、52之重疊區域中沿球外罩之整個圓周施加均勻加熱。可使用諸如鏈條、齒輪及其類似者之旋轉構件317或甚至手動地旋轉球外罩。在一起加熱半球形外罩部分50、52並按需要將囊20充氣之後，形成運動球10。經加強之外罩30因此包含具有複數個板片之外罩材料，其中沿外罩材料之內部板片邊界以及以前的「自由」邊緣(在熱結合之後不再為自由的)熱結合加強材料。插入至球外罩之半球形外罩部分中之一者中的孔洞55中之氣閥25允許按需要對囊20充氣或放氣。
圖10A及圖10B說明用於將球外罩之半球形外罩部分50、52中之每一者熱結合在一起的第二例示性模製裝置400。模製裝置含有第一電極412及第二電極414，其兩者連接至一可操作以在電極之間產生交流電場的電磁能量源(未圖示)。電極412、414的形狀較佳為半球形，但亦可構成大體上駐留於球之兩個半球形外罩部分50、52之重疊區段51上方及下方的環。交流電場可以在1 MHz至500 MHz之範圍中的頻率產生，較佳以在10 MHz至200 MHz之範圍中的頻率產生，且最佳以在27.12 MHz或40.68 MHz產生。通常，施加能量歷時約10至40秒(例如，約10、15、25、30、35或40秒)。第一外部模具416及第二外部模具418亦包括於裝置內，第一外部模具416及第二外部模具418一起在其之間界定球模穴。如圖10A中所展示，第一模具416及第二模具418各自容納經加強之球外罩30的半球形外罩部分50、52。因此，模具416、418較佳含有用於容納外罩中之板片的板片凹座及用於容納內部板片邊界的突起。
模製裝置400亦包括一包含諸如聚乙烯或聚丙烯之介電材料的環422，該環422分離電極412、414。在圖10A中，說明當模製裝置處於閉合位置時的兩個介電材料環，鄰近於第一電極412之一環422a，及鄰近於第二電極414的另一環422b。亦應瞭解，環422可包含第一模具416及第二模具418之亦包含介電材料的部分。介電材料環422具有約為兩個半球形外罩部分50、52中之每一者的重疊區段51之大小的寬度，該兩個半球形外罩部分50、52熱結合在一起以形成最終球10。銷、螺釘、鎖、榫/溝槽或其他接合構件可用以將模具緊固在一起。
為了根據此實施例建構遊戲球，分離流動模製裝置之第一模具416與第二模具418。將經加強之球外罩30的第一半球形外罩部分50及第二半球形外罩部分52置放於模具之模穴內(連同囊20，為了清晰在圖10A中未展示)。使模具閉合，且(如上文大體上所描述，經由模具及半球形外罩部分中之一者中的孔洞)使囊充氣(通常在0.6與0.8巴之間)。囊充當內部模具以有助於使兩個半球形部分保持對準。較佳使用介電加熱將經加強之球外罩30的第一半球形外罩部分50及第二半球形外罩部分52熱結合在一起。在兩個電極之間產生交流射頻電場能量。應瞭解，半球形外罩部分50、52之介電常數大於囊20內之空氣的介電常數，且亦大於模具416、418及介電環422a、422b的介電常數。舉例而言，在典型實施例中，囊內之空氣之介電常數為約1，介電環之介電常數為約2，外部模具416、418之介電常數為約3，且半球形外罩部分的介電常數為約6。結果，電流優先穿過位於第一電極412與第二電極414之間的重疊區段51中的半球形外罩部分50、52。結果，與交流電場相關聯之能量被優先導引至兩個半球形外罩部分50、52之重疊區段之間，藉此將兩個半球形外罩部分50、52熱結合在一起。在將半球形外罩部分50、52熱結合在一起之後，形成最終運動球10。經加強之外罩因此包含複數個板片之外罩材料，其中沿外罩材料之內部板片邊界以及以前的「自由」邊緣(在熱結合之後不再為自由的)熱結合加強材料。插入至球外罩之半球形外罩部分中之一者中的孔洞55中之氣閥25允許按需對囊20充氣或放氣。
圖10C說明大體上展示於圖8A及圖8B中的球外罩之兩個半球形外罩部分50、52在熱結合製程期間的對準。在例示性實施例中，每一半球形外罩部分50、52之邊緣包含與第二多邊形板片(五邊形板片44)交替之第一多邊形板片(六邊形板片46)。六邊形板片46各自具有三個末端六邊形板片邊緣：完全無加強材料之第一末端六邊形板片邊緣45a，及一部分由來自加強材料坯料65之重疊加強材料覆蓋的第二末端六邊形板片邊緣45b及第三末端六邊形板片邊緣45c。亦即，如最佳在圖8B及圖10C中所展示，第二末端六邊形板片邊緣45b及第三末端六邊形板片邊緣45c各自具有無加強材料之第一末端六邊形板片邊緣部分47，及具有重疊加強材料的第二末端六邊形板片邊緣部分49。五邊形板片44各自具有藉由重疊加強材料覆蓋之末端五邊形板片邊緣45d(圖8B及圖10C)。
圖10C說明兩個半球形外罩部分50、52在模穴內如何對準。來自第一半球形外罩部分50之第一末端六邊形板片邊緣45a(無加強材料)中的每一者與來自第二半球形外罩部分52之具有重疊加強材料的末端五邊形板片邊緣45d中的每一者對準。另外，來自第一半球形外罩部分50之一部分藉由重疊加強材料覆蓋的第二末端六邊形板片邊緣45b及第三末端六邊形板片邊緣45c中之每一者與來自第二半球形外罩部分52之一部分藉由重疊加強材料覆蓋的第二末端六邊形板片邊緣45b及第三末端六邊形板片邊緣45c對準。亦即，來自第一半球形外罩部分50之無加強材料的第一末端六邊形板片邊緣部分47與來自第二半球形外罩部分52之具有重疊加強材料的相應第二末端六邊形板片邊緣部分49對準。結果，當兩個半球形外罩部分50、52如此對準時，加強材料上覆所有末端邊緣45a、45b、45c且與所有末端邊緣45a、45b、45c重疊。接著將熱結合應用至半球形外罩部分50、52(較佳限於重疊區域51)，使得兩個半球形外罩部分形成最終球10。應瞭解，此對準可用於在圖9或圖10中說明之例示性模製裝置中的任一者。
在另一例示性實施例中，在一經調適以在單一步驟中形成經加強之外罩30的流動模製裝置500中將外罩板片坯料35熱結合至加強材料坯料65。亦即，在單一步驟中形成整個球形經加強之外罩30，而非在第一步驟中形成兩個半球形外罩部分50、52(或複數個其他部分)接著在第二步驟中將其熱結合在一起。
在圖11中說明例示性流動模製裝置500。一般而言，流動模製裝置包括一外部電極512及一收容於囊20中的內部導電流體。內部導電流體充當內部電極514。外部電極512及內部電極514兩者連接至一可操作以在電極之間產生交流電場的電磁能量源(未圖示)。外部模具516亦包括於裝置內。囊20充當內部模具518。模穴界定於外部模具516與內部模具(囊)518之間。總體組態(外部電極512及外部模具516兩者)的形狀為球形，儘管外部電極512及外部模具516可包含複數個區段550、552以准許外罩板片坯料35、加強材料坯料65、囊20及最終球10進出該裝置之置放及移除。外部模具516含有用於容納外罩板片坯料35中之板片圖案40中之相應板片的複數個圖案化之板片凹座517a，及待與外罩板片坯料35之內部板片邊界43及自由邊緣48對準的突起517b。另外，外部電極及外部模具512具有至少一孔洞519，在該孔洞519中，導電流體514可經注入或移除，及/或射頻產生器可附接至電極。
為了建構根據此實施例的足球，分離流動模製裝置之第一區段550與流動模製裝置之第二區段552。接著在外部模具516之相應板片凹座517a內對準外罩板片坯料35的多邊形板片。對準突起517b與外罩板片坯料35之內部板片邊界43及自由邊緣48。接著將加強材料坯料65置放於外罩板片坯料35上，使得外罩板片坯料35之內部板片邊界43及自由邊緣48與加強材料坯料65對準。膠帶或其他黏著劑可用以將加強材料坯料65臨時緊固至外罩板片坯料35。接著使模製裝置之區段550、552閉合。可經由孔洞519將額外液體導電材料注入至囊20中，以確保囊填滿模穴內部並提供足夠壓力。液體導電材料推動囊20抵靠加強材料坯料65及外罩板片坯料35，且因此囊20充當內部模具418。
接著在外部電極512與內部電極514之間產生交流電場。交流電場可以在1MHz至500MHz的範圍中之頻率產生，較佳以在10MHz至200MHz的範圍中之頻率產生，且最佳以27.12MHz或40.68MHz產生。模製裝置之區段550、552接著經開啟以移除具有經加強之外罩30的球10。經加強之外罩因此包含複數個板片之外罩材料，其中沿外罩材料之內部板片邊界以及以前的「自由」邊緣(在熱結合之後不再為自由的)熱結合加強材料。可接著經由孔洞519移除液態導電流體，且可使用已插入至孔洞519中之氣閥25藉由空氣或其他氣體使囊20充氣。
雖然前述實施例利用藉由導電流體填滿之囊20作為內部電極514，但內部電極可包含其他材料。舉例而言，內部電極514可包含已塗佈有導電材料(諸如，銀)之囊20。囊20可藉由液體或氣體(諸如，水)填滿。囊20上之導電材料塗層因此在熱結合製程期間充當內部電極514。
如上文所論述，關於各種例示性實施例來描述本發明。在一實施例中，經加強之外罩30包含兩個半球形外罩部分50、52，該等半球形外罩部分50、52包含球外罩的大約50%。每一半球形外罩部分包含熱結合在一起之外罩板片坯料35及加強材料坯料65。半球形外罩部分50、52中之每一者接著熱結合在一起以形成完整球10。在第二實施例中，外罩包含外罩板片坯料35及加強材料坯料65，其在單一步驟中熱結合在一起以形成球形經加強之外罩30，使得不形成中間半球形外罩部分50、52。
根據前述內容，應瞭解，可利用一或多個外罩板片坯料35及一或多個加強材料坯料65。舉例而言，外罩板片坯料中之每一者可包含球外罩之約10%、20%、30%、40%、50%、60%、70%、80%、90%，或其某一組合。作為更特定實例，可使用四個包含兩個六邊形板片及一五邊形板片之外罩板片坯料，及第五個包含兩個五邊形板片及兩個六邊形板片的外罩板片坯料形成半球形外罩部分。亦即，第一外罩板片坯料將包含內部五邊形板片44a、內部六邊形板片46a、外部六邊形板片46f及外部五邊形板片44b。第二外罩板片坯料將包含內部六邊形板片46b、外部六邊形板片46g及外部五邊形板片44c。第三外罩板片坯料將包含內部六邊形板片46c、外部六邊形板片46h及外部五邊形板片44d。第四外罩板片坯料將包含內部六邊形板片46d、外部六邊形板片46i及外部五邊形板片44e。第五外罩板片坯料將包含內部六邊形板片46e、外部六邊形板片46j及外部五邊形板片44f。外罩板片坯料35之各種圖案及組態為基本上無限的。同樣，加強材料坯料65之多邊形外形不需要鏈接在一起，且每一多邊形之區段可被分離地製造(例如，五邊形之兩個邊)。本發明預期到外罩板片坯料35及加強材料坯料65之各種組合，只要加強材料與內部板片邊界對準便可。
可以預料，根據本發明製造之運動球具有增強球之效能的結構元件。加強材料模擬習知運動球之總體組態，在習知球中，個別板片被手縫在一起以製造內部接縫。然而，與在手縫時可能具有瑕疵之球形成對比，藉由模製外罩，運動球為完全球形的。此外，藉由消除對外罩中縫合接縫的需要，可製備不透水之球。另外，外罩之結構繼續允許球在衝擊部位處變形。結果，在足球之狀況下，例如，足球將以類似於其中將板片手縫在一起之習知足球的方式旋轉。一般而言，相較於使用手縫板片製造之習知相應運動球，具有根據本發明之外罩的球應實際上更快地回彈至其原始形狀。此情形為有利的，此係因為根據本發明製造之運動球在空中將展現較少擺動。
自前述內容將可見，本發明為十分適於達成上文中所闡述之所有目的及目標連同為顯而易見且對於本發明為固有之其他優點的發明。由於許多可能實施例可由本發明製成而不偏離本發明之範疇，因此應理解，本文中所闡述或在隨附圖式中所展示之所有事項應解譯為說明性，且非限制性含義。雖然已展示並論述了特定實施例，但當然可進行各種修改，且本發明並不限於本文中所描述之部分及步驟的特定形式或配置，除了此等限制包括於以下申請專利範圍中的情況之外。另外，應理解，某些特徵及子組合具有效用，且可使用而無需參考其他特徵及子組合。此情形由申請專利範圍預期到，且係在申請專利範圍之範疇內。
