ABSTRACT Moulded bodies produced from a mixture of comminuted fibrous materials and a thermo-setting binder are provided with a protective and/or decorative coating during the mould- ing operation by placing a protective sheet or film, for example of paper over which a transparent protective synthetic resin layer is disposed. The mixture is first cold moulded without the covering layer to form a preliminary blank or so-called pre-pressing which is then hot-moulded in two stages. In the first stage the uncoated blank is compressed to a pre-determined volume greater than the desired volume of the finished body and after opening the mould and placing the covering layer over the pressing, the mould is closed and the coated blank is compressed in the second stage to its desired volume and cured, thereby bonding the protective layer to the body. A moulding apparatus is disclosed comprising upper and lower heated mould parts movable respectively toward and away from each other and removable spacer means insertable between abut- ment members on the mould parts to alter the spacing between the mould parts between a first and a second hot moulding sta?e.
