Abstract

1,273,906. Continuous form stationery. UARCO Inc. 30 April, 1970 [5 May, 1969], No. 20782/70. Headings B6A and B6P. Continuous form stationery comprising several plies and intended to be folded along weakened transverse lines into a zig-zag stack has adjacent one or both edges crimped parts 46, 48, 50, 52, Fig. 7, causing inter-engagement of the plies, each crimped part, e.g. part 48 being formed by slitting each ply transversely at lines 48a, 48b so as to be connected to the ply at the ends 48c, 48d and then pressing the part out of the plane of its ply. The arrangement prevents relative lengthwise movement of the plies and arching of the plies caused by such movement. As shown, Fig. 6, the plies have lines 40 of so-called cold glue securing the plies together, lines of glue 38 securing a narrower carbon ply 18 to the underside of each form ply, and pin-feed holes 30 between the glue lines. A set 44, Fig. 6, of four crimped parts is proprovided between alternate pairs of holes 30, but in the embodiment, Fig. 7, a transverse pair of crimped parts are provided between each pair of holes 30. The crimping may be effected after the plies have been glued together and each crimp may extend completely through the assembly. The inner crimps extend through the carbon plies.
