Abstract

1398709 Laminates BPB INDUSTRIES Ltd 12 July 1972 [12 July 1971 22 May 1972] 32635/71 and 23991/72 Heading B5N [Also in Division E1] A building board comprising a gypsum core 10 paper or plastics facing sheets 12 and a reinforcing strip 23 along at least one edge is manufactured by cutting a groove in the edge of the core, placing the reinforcing strip against the prepared edge and bending the facing sheets over the strip and adhering them thereto. The reinforcing strip may be T-section (as shown), or U-section or Y-section or stepped U- section. The edges of the board may be tapered. The edges of the boards are cut by rotary saws and guide plates may be provided to hold back the paper sheets whilst a disc tool presses the reinforcing strip into position. A hot melt adhesive is applied and a pressure roller folds down the edges of the sheets.
