ABSTRACT:
A continuous business forms assembly comprising a zig-zag folded stack of a multiplicity of superimposed, elongated plies of paper, including a plurality of intermediate plies. Each of the plies is provided with a longitudinally extending, control punch margin and the plies are held in assembled relation by longitudinally extending glue lines between adjacent plies adjacent the control punch margins. Individual form lengths in the assembly are defined by cross lines of weakening in the plies and the intermediate plies are completely severed in the area of at least the ones of the cross lines on which the assembly is folded and provided with reliefs thereat so that stresses caused by folding the assemblies into the stack are relieved to prevent tenting.
