Abstract
A method of making injection moulded plastic objects with one, two or three imbedded decorative and/or descriptive prints comprises the steps of placing the prints on relatively thin foils (4, 5) of an extent corresponding to the cross-section of the mould cavity (6), and placing the foils (4, 5) in the mould cavity (6) with respect to the runner (3) so that the foils are pressed into engagement with the bottom and/or top of the mould cavity by the moulding material injected under pressure. Thus, a plastic object with imbedded colored motifs at both the top side and the underside can be made by just one moulding operation.
Claims3

- (a) placing foils in two halves of the mould;
- (b) inserting a pin inside of said mould in such manner that said pin will go through the foil located in one half of the mould and will support the foil located in another half of the mould, whereby said foils are kept separately from each other;
