Description
用の部品を製造することができる。例えば、スポーツ靴用の靴底は、エチレン酢酸ビニル(EVA)、熱可塑性ポリウレタン(TPU)、ゴム、ポリプロピレン(PP)、またはポリスチレン(PS)から製造することができる。これらの異なる材料の各々は、それぞれのタイプのスポーツ靴の特定の要求に応じて、特定のタイプのスポーツ靴の靴底に多かれ少なかれよく適している異なる特性の特定の組み合わせをもたらす。例えば、TPUは、大変耐摩耗性があるとともに引裂き抵抗があり、発泡EVAは、大きな緩衝性をもたらす。
に接触している場合に一部加熱および/または冷却、あるいは調整された型の移動によって成すことができる型表面の定められた領域で溶融および凝固され得るとも考えられる。したがって、厚さを局所的に変更する上述の態様は、機能化された性能特性を有するスポーツ用品を製造するためにさらなる改善がされ得る。
類の材料から作製されるスポーツ用品を提供するだけでなく、スポーツ用品のデザインを調整するオプションも与えることができる。
a.型(105;205;305;405)の中に第1の材料を堆積させるステップと、
b.型(105;205;305;405)を振動させ、型(105;205;305;405)内の第1の材料の分布を変更するステップとを含む方法。
a.型(105;205;305;405)の中に第1の材料を堆積させるステップと、
b.好ましくは型の局所的な熱源および/または冷却源を用いることによって、または型に局所的に作用を及ぼすことによって、第1の材料の選択部分を選択的に少なくとも一部溶融するおよび/または凝固させるステップとを含む方法。
d.型を振動させ、型(105;205;305;405)内の第2の材料の分布を変更するステップと、
e.第2の材料の少なくとも一部を少なくとも部分的に溶融するおよび/または凝固させるステップと
をさらに含む、[1]~[9]のいずれかに記載の方法。
。したがって、型105は、完成したスポーツ靴の雌型である。雌型105はスポーツ靴の一部、例えば靴底のためだけのものとすることができ、靴の甲革は例えば赤外線を用いた溶接によって別個の製造プロセスにおいて成形された靴底と接合されることも考えられる。
そのような保持手段130は、雌型105内の第1の材料および/または第2の材料の分布を変更するために、例えば(図1に示されていない)ロボットアームを振動させる装置と接続することができる。保持手段130は、ネジ、ナット、クランプ、磁石、または任意の他の適切な手段によってロボットアームと接続することができる。雌型105の一部分、例えば下部分120は、ロボットアームに永久的に固定することができ、またはロボットアームの一部であることさえもできるということも考えられる。保持手段130は、型105を振動させる装置の別の領域内、例えば、かかと領域内、中足領域内、雌型105の側面または中央側に配置することができるとも考えられる。さらにまたは代替として、複数の保持手段130を使用することもできる。
な技法によって繊維が機能化できるとも考えられる。さらにまたは代替として、型205は、2つ以上の部品を備えてもよく、および/または図1中の雌型105を参照して説明されるような雌型としてもよい。さらに、第1の材料は、それが堆積できるように型205の中にハンドフィルすることができる。
さらに、発泡粒子は、型の内側にランダムにまたはあるパターンで配置することができる。
