Shaping panels of microporous thermal insulation.

摘要

At least one edge of a substantially planar panel (2) of microporous thermal insulation material is shaped by first restraining the planar faces of the panel so as to resist deformation of the faces of the panel adjacent to the edge of the panel to be shaped. A forming member (14; 24) is then urged against the edge of the panel so as to shape the edge, the forming member being profiled such as to cause the edge of the panel to be recessed. The forming member is then removed from the edge of the panel so as to permit the panel to adopt a relatively square edge, and the planar faces of the panel are released. <IMAGE>
