Abstract of the Disclosure A method of filling a press mould with a pourable but at most limitedly flowable substance, e.g. fibrous material and a thermosetting binder, for producing a pre- form or a finished three-dimensional article by pressing, in which a forming space of a configuration substantially corresponding to that of the preform or article to be made is defined between a perforated bottom of a container for the substance and the lower mould part and vibrating the perforated bottom or the container to introduce and compact the substance into the forming space to the required config- uration and depth. The apparatus for carrying out the method comprises a removable container for placement over the lower part of the press mould having a grating or sieve at its bottom. Conventional vibrating means are mounted on or connected to the container with the inter-position of resilient damping means for causing vibratory movements in one or more directions to cause a dosed amount of the sub- stance to be admitted to the mould bottom in the desired amounts. The method and apparatus can be used to produce a preform or pre-pressing in the cold for subsequent finish pressing in a heated mould or to produce the finished article in one and the same press mould. - 1 -
