A composite product and a method of making the product, the product being a central panel of flexible sheet material having a peripheral molding of plastics bonded to the margin of the panel, the arrangement being such that the margin of the panel is deformed to define two marginal parts displaced out of the plane of the central part of the panel, the moulding extending across the junction of the two marginal parts with each other but stopping short of the junction of the inner marginal part with the central part so that the blank at that junction is free to unwind, i.e. return to the flat and any bowing of the blank, which being uniform as to direction, is substantially less than would be the case were the moulding to cover both junctions. |
