Abstract

686,251. Fibrous board &c. OMAN. E. March 7, 1950. [March 12, 1949] No. 5726/50. Class 96. Porous boards &c. made from straw pulp, e.g. with wood fibre, or bark, &c. are dried on a perforated support and then separated therefrom by forcing a wedge-tool between the board and support. The wedge may have gaps in the thin edge corresponding to the width of openings in the support and the under-side of the support may be brushed or scraped before or during separation. Specifications 671,251, 673,767 and 686,250, [Group IV (a)], are referred to.
