Method for manufacturing a molded article, in particular for interior linings of vehicles with the use of a substrate layer made of plastic, comprising a contact side and rear side that lies opposite to said contact side and a cover layer or decorative layer in the form of a plastic film that is edge folded at least in an edge section of the substrate layer comprising a visible side formed by a lamination foil and a rear side formed by a foam layer, the layers resting one on top of the other as an arrangement in a tool, the method comprising: ▪ inserting the substrate layer with an inner area of the cover layer or decorative layer and the substrate layer between two tool parts of a tool, wherein the cover layer or decorative layer with its visible side lies adjacent to the first tool part and the substrate layer with its rear side lies adjacent to the second tool part sot that the connecting sides of the cover layer or decorative layer and of the substrate layer lie adjacent to each other, wherein an edge piece of the cover layer or decorative layer, which edge piece extend at least along a section of an outside edge of the cover layer or decorative layer, extends beyond a section of an outside edge of the substrate layer, which section extends along said edge piece of the cover layer or decorative layer, thus forming an exposed rear area, ▪ heating a heating tool and moving of the heated heating tool towards the exposed rear area of the edge piece, provided for edge folding, of the cover layer or decorative layer that is joined to the substrate layer, for a predetermined period of time such that the surface area at the exposed rear area is melted, ▪ moving an edge-folding slider from a position in which a first side of the edge-folding slider lies adjacent to the visible side of the edge piece of the cover layer or decorative layer that extends beyond the outside edge section of the substrate layer, to a position in which a second side of the edge-folding slider presses a section of the cover layer or decorative layer against the outside edge of the substrate layer, wherein edge piece is swung in the direction of its edge-folding position, ▪ moving the edge-folding slider to a position in which an contour area of the edge-folding slider lies adjacent to the visible sided of the cover layer or decorative layer, wherein the edge-folding slider is moved to this position in such a manner that the edge piece of the cover layer or decorative layer that extends beyond the outside edge section of the substrate layer with its melted rear side lies adjacent to the rear side of the substrate layer; and ▪ pressing the edge-folding slider with the contour area to the visible side of the edge-folded edge piece against the substrate layer for bonding the cover layer or decorative layer to the substrate layer in the edge-folded area. ▪ inserting the substrate layer with an inner area of the cover layer or decorative layer and the substrate layer between two tool parts of a tool, wherein the cover layer or decorative layer with its visible side lies adjacent to the first tool part and the substrate layer with its rear side lies adjacent to the second tool part sot that the connecting sides of the cover layer or decorative layer and of the substrate layer lie adjacent to each other, wherein an edge piece of the cover layer or decorative layer, which edge piece extend at least along a section of an outside edge of the cover layer or decorative layer, extends beyond a section of an outside edge of the substrate layer, which section extends along said edge piece of the cover layer or decorative layer, thus forming an exposed rear area, ▪ heating a heating tool and moving of the heated heating tool towards the exposed rear area of the edge piece, provided for edge folding, of the cover layer or decorative layer that is joined to the substrate layer, for a predetermined period of time such that the surface area at the exposed rear area is melted, ▪ moving an edge-folding slider from a position in which a first side of the edge-folding slider lies adjacent to the visible side of the edge piece of the cover layer or decorative layer that extends beyond the outside edge section of the substrate layer, to a position in which a second side of the edge-folding slider presses a section of the cover layer or decorative layer against the outside edge of the substrate layer, wherein edge piece is swung in the direction of its edge-folding position, ▪ moving the edge-folding slider to a position in which an contour area of the edge-folding slider lies adjacent to the visible sided of the cover layer or decorative layer, wherein the edge-folding slider is moved to this position in such a manner that the edge piece of the cover layer or decorative layer that extends beyond the outside edge section of the substrate layer with its melted rear side lies adjacent to the rear side of the substrate layer; and ▪ pressing the edge-folding slider with the contour area to the visible side of the edge-folded edge piece against the substrate layer for bonding the cover layer or decorative layer to the substrate layer in the edge-folded area.
