Abstract

1396288 Finishing edges of sheet material BPB INDUSTRIES Ltd 17 July 1972 [15 July 1971] 33354/71 Heading B5K [Also in Division E1] A covered edge on plasterboard 10a, comprising a gypsum core 13, a facing sheet 12 and a backing sheet 11, is characterized in that the sheet 12 is folded over the edge face of the core 13 and over the edge portion 11b of the sheet 11, the overlapping portions 11b, 12b of the sheets 11, 12 being thinner than the main portions of the sheets and the sheet 12 being adhered to the sheet 11. Preferably, the sheets 11, 12 are of paper. To cover a cut or damaged edge, the core 13 of the board 10a is rebated at 14, immediately above the sheet 12, to leave a projecting portion 12a, Fig. 1B. The unwanted portion of the core 13 and the sheet 11 is cut away and the inner surface of the sheet 12 is scored at 15 and the edges of the sheets 11, 12 are thinned at 11b, 15b, Fig. 1c (not shown). A band or bead 16 of hot melt adhesive is applied to the portion 12a, Fig. 1D, which is then folded up against the edge of the core 13 and the edges 11b, 12b overlapped, Fig. 1E (not shown). Pressure is applied to effect bonding. Apparatus for forming the finished edge, Figs. 2 and 3, comprises (a) a table 20 along which a board is positively advanced; (b) a vertical driven circular cutter 21 to cut a board to a desired working width wider than the desired finished width; (c) a horizontal drive, circular cutter 22 having an adjustable blade 23 to form the rebate 14; (d) a cutter 24 having a vertical circular blade 26 to remove the unwanted portion of the core 13 and the sheet 11 and to form the score 15, a guide 27 to remove the severed portion, auxiliary blades 28 adjustably mounted on the blade 26 to form the thinned edge 11b and a blade 29 mounted skew on the axis of the blade 26 to form the thinned edge 12b; (e) a dust collection hood 25 over the cutters 22, 24; (f) a dust collector 31; (g) an adhesive applicator 32; (h) folding guides 34 loaded by springs 35 and (i) a guide 36 to align the boards as they pass along the table 20.
