- 前記潤滑相の前記添加剤が脂肪酸エステル、脂肪酸エステルエトキシレート、パラフィン油、生分解性菜種油のような植物油、またはこれらの組合せである、請求項2から5の何れかに記載の製造方法。
- 前記添加剤が、軟化剤、多価アルコール、アミン、アルコールエトキシレート等の他の成分とともに添加される、請求項1から6の何れかに記載の製造方法。
- 前記添加剤は、特に着色液を形成する添加剤は、調量手段(30)により外部から前記プラスチック材料が少なくとも部分的に可塑化されて存在する部位に位置する前記押出手段(18)へと供給される、請求項1から7の何れかに記載の製造方法。
- 前記プラスチック材料の可塑化状態及び/またはその温度(T)に対応する量の前記着色液が、前記成形エレメント(16,17)を備える前記支持ウェブ(10)の着色度が均一となるように、前記調量手段(30)によって供給される、請求項8記載の製造方法。
- 前記添加剤は、特に着色液を形成する添加剤は、ホース調量ポンプから供給されることにより前記押出手段(18)の入り口に達し、
前記ホース調量手段は、例えば、プラスチックの顆粒を供給するための投入手段(24)に設けられている、前記押出手段(18)より前段にある投入ゾーン(20)内に設けられている、または投入ゾーン(20)の前段に直接設けられている、請求項1から9の何れかに記載の製造方法。 - 前記支持ウェブ(10)及び/または前記成形エレメント(16,17)は同時に押出成形され、または同時に押出成形され得る個々の層で構成される、請求項1から10の何れかに記載の製造方法。
- 押出ノズル(1)及び色素調量手段(30)が設けられた押出手段(18)を有し、前記押出手段は個々の層を同時に押出成形する、請求項11記載の製造方法。
- 前記押出手段(18)内の着色液は、前記色素調量手段(30)によって、前記プラスチック材料が前記押出ノズル(1)へと進む均質化ゾーン(28)で前記プラスチック材料に供給される、及び/または前記プラスチック材料が前記押出手段(18)に供給されるポイントに隣接するポイントで前記プラスチック材料に供給される、請求項1から12の何れかに記載の製造方法。
