Title: A process of manufacturing artificial masses
Filed: 1933-01-18
Abstract: Materials such as synthetic resins, rubber, casein, cellulose, and sodium silicate are brought into a sticky condition and introduced by pressure into a fibrous mass such as a card web in which the fibres are distributed uniformly in all directions so as to form a homogeneous composition which can be dried and vulcanized or otherwise treated.  The sticky material may be introduced into the web by means of pressing cylinders, or by mixing in a colour mill. The impregnated mass may be moulded into a homogeneous cylindrical block; after hardening but while still hot it is cut to a suitable thickness by a peeling machine. Adhesive or colouring materials or lacquers may be applied on one or both sides of the mass or a pattern may be impressed thereon. Webs of wool, cotton, jute, artificial silk or asbestos may be treated.  A phenol formaldehyde condensation product and the substance known by the Registered Trade Mark "Revertex" may be used as impregnating materials.
