- 金型(2)及びその中に含まれている成形品(1)の変形中に、成形輪郭(4)は少なくとも特殊輪郭領域(5)の範囲で機械的破損によって破壊される、請求項1~12のいずれか一項に記載の方法。
- 金型(2)の変形は、金型(2)に圧力を加えることによって行われる、請求項13に記載の方法。
- 所定数の成形品アンダーカット領域(3)を有する弾性変形可能な成形品(1)を金型(2)を用いて製造するための装置であって、
成形品材料を金型(2)に導入するための手段であって、所定数の成形品アンダーカット領域(3)を成形品(1)に成形するように構成される所定数の特殊輪郭領域(5)を備える成形輪郭(4)を有している手段と、
成形品(1)を金型(2)から取り出すための手段とを有し、金型(2)がその中に含まれている成形品(1)と共に少なくとも部分的に変形される結果、成形品(1)が弾性的に変形して、金型(2)は少なくとも部分的に、且ついかなる場合も特殊輪郭領域(5)の範囲において破損する装置。 - 請求項1~14のいずれか一項に記載の方法によって製造された弾性変形可能な成形品(1)を含む物品、特に靴。
