A method of shaping a body, suitably a body for use in the building or furnishing industry, comprising engaging a surface region of the body with a tool having a predetermined profile, and effecting relative movement between the body and the tool in a direction generally parallel with a surface of the said region, the body being formed of a material which is sufficiently friable for material which is engaged by the tool during the relative movement to be removed from the body but sufficiently rigid for adjacent material to remain attached, whereby the said surface region is formed with a recess having a profile corresponding to the predetermined profile of the tool. The method is particularly suitable for the profiling of plaster materials and rigid plastics foam especially phenolic foams of kind obtained by the method of EP-A-0010353. |
