Abstract
928,462. Corrugating sheet material. J. F. SUMMERSGILL. Feb. 1, 1960 [Feb. 5, 1959], No. 4083/59. Class 42 (2). [Also in Group V] Corrugated reinforced synthetic resin sheets are produced by passing reinforcing material, e.g. glass fibre, through a bath of synthetic resin, e.g. polyester resin, so as to impregnate it with the resin, applying regenerated cellulose sheet to the surfaces of the resinimpregnated reinforcement to form a laminate, and passing the laminate sheet 1, together with a similar one 2 positioned below it, to a corrugating machine comprising upper, lower and intermediate chains 3, 4 and 5, respectively, of mould bars, the upper laminate sheet 1 being fed between the upper and intermediate mould bars 3, 4 and the lower laminate sheet 2 between the intermediate and lower mould bars 4, 5 so as to be subjected to pressure therebetween, and the two laminate sheets 1, 2 together with the chains 3, 4 and 5 are passed through a polymerizing or curing chamber 16. Where four corrugated sheets are to be produced simultaneously, each laminate sheet comprises two plies of resin-impregnated material between and on either side of which are regenerated cellulose sheets. After corrugating, the resin-impregnated sheets are separated by parting them along the centrally situated sheet. Detached lengths of the chains of mould bars are transferred from the exit to the entry end of the machine as operation proceeds by a sling 30. The reinforcing material may be glass fibre or other high or low wet strength fibres, preferably in the form of paper or chopped glass fibre mat. Where the reinforcement is of low wet strength the sheets must be moved through the machine slowly to prevent rupture of the fibres while, on the other hand, a high wet strength reinforced sheet may be moved more rapidly. In this connection, the heated chamber 16 is of adjustable length and the upper and lower chains 3, 5 may be made continuous (as shown in broken lines) while the intermediate chain 4 may have some sections removed.
