发明名称 Method and mould for manufacturing polyurethane articles.
摘要 For manufacturing a moulded article comprising at least an elastomeric polyurethane skin (9) and optionally a structural backing layer (10) and an intermediate foam layer (12) a mould is used having at least a first mould part (1) comprising at least two mutually movable mould sections (2-4). The skin (9) is moulded with its front against a surface (7) of the first mould part (1) by applying at least one reactive polyurethane mixture to this mould surface. In order to prevent the seam between the mutually movable mould sections (2-4) of the first mould part to leave traces on the front of the moulded skin (9), the first mould part (1) further comprises a removable, flexible liner (6) which is positioned onto these mould sections to cover at least partially the seam therebetween. Since the first mould part (1) comprises mutually movable mould sections (2-4), the design freedom is increased and it is not required to transfer the skin to another mould for providing relatively rigid backing layers to the back of this skin. <IMAGE>
