Abstract:
1. A method for manufacturing a moulded article comprising at least an elastomeric polyurethane skin, showing a front and a back, and a structural backing layer, which method comprises the steps of: providing a mould which has a mould surface and which comprises at least a first mould part comprising at least two mutually movable mould sections forming at least one seam and showing at least one undercut, and a removable flexible liner which is made of an elastic material; positioning the flexible liner onto said mould sections to cover at least partially said seam and to form at least a portion of said mould surface which has a generally concave shape; applying at least one reactive polyurethane mixture to said mould surface to mould said skin with its front against this mould surface; uniting the structural backing layer to the back of the skin; moving the mutually movable mould sections away from one another while leaving the flexible liner onto the moulded article; removing the moulded article from the mould and the flexible liner from the moulded article; and repositioning the flexible liner onto said mould sections and again moulding a skin against the mould surface.
