Abstract: A manifold set including index tabs to facilitate filing and indexing of the components thereof, including a plurality of superimposed sheets of paper and glue lines securing the sheets together adjacent a corresponding edge of each sheet. Image transfer material is disposed at the interface of adjacent sheets for transferring the image placed on the uppermost sheet to corresponding locations on the lower sheets and lines of weakening are located in each sheet inwardly of the edge and of the glue. Each line of weakening has a linear part and a bulbous part and extends across the set. The linear parts of each line of weakening are aligned across the set and the bulbous parts of each line of weakening are staggered across the set so that when the lines are broken, a plurality of individual sheets having individual, staggered index tabs, are provided.

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.

Abstract: Stationery printing apparatus for printing indicia at a predetermined position on each form length of continuous business forms stationery assemblies. The apparatus embodies a unique arrangement of a printing device in connection with a form feeding device and lineup indicia so that positive, accurate registration between the printing device and the predetermined position on each form length for receipt of the printing is obtained before a printing is initiated, thereby eliminating any need for registration adjustment during a printing run.

Abstract: An improved continuous envelope assembly including an elongated ply of paper having control punch margins along longitudinal edges thereof, individual envelopes in the assembly being delimited by transverse lines of weakening extending across the assembly, die cuts in the ply adjacent both longitudinal edges thereof and adjoining the lines of weakening at one side thereof to define the corners of envelope flaps, first glue lines on the ply adjacent the lines of weakening and on the sides thereof opposite the die cut, individual sheets having widths less than the ply and lengths less than the distance between the lines of weakening secured to the ply by the first glue lines, the ply longitudinal edges being folded over the longitudinal edges of the individual sheets, second glue lines securing the ply longitudinal edges to the sheet longitudinal edges, the control punch margins being reverse folded away from the sheets to extend to the sides of the respective sheets longitudinal edges.

Abstract: An improved burster for separating continuous business forms stationery assemblies into individual form lengths of the type including an infeed mechanism for driving the continuous assembly into a burster which, in turn, separates the assembly into individual form lengths which are placed on a conveyor to be conveyed to a stacking tray. The burster includes a powered mechanism whereby the burster, the conveyor, and a portion of the stacking mechanism may be simultaneously adjusted for various form lengths. Also incorporated is an automatic electrical system responsive to such adjustment for automatically adjusting the conveying rate of the conveyor to insure proper shingling of the individual form lengths thereon. The burster is in a housing having a movable cover whereby access to the various mechanisms may be obtained. A control system provides for jogging of the mechanisms with the cover open that precludes continuous operation for safety purposes.

Abstract: An improved deleaver for a continuous business forms assembly for separating the stationery plies and interleaved carbon plies from each other. The invention features a unique carbon turning bar assembly whereby the same is permanently affixed to the machine and yet may be moved between operative and inoperative positions, the latter being used when continuous business forms assemblies not having interleaved carbon are being processed. Also featured is a door in the wall of the first chute which may be selectively opened or closed. When extremely large forms are being processed such that they cannot rest generally parallel to the bottom of the first chute, the door may be opened to allow efficient processing.

Abstract: An improved deleaver for separating the plies of multiple-ply, continuous business forms stationery assemblies with or without interleaved carbon plies. The deleaver includes an input end and an output end having a plurality of ply-receiving pockets. Intermediate the output end and the input end is a first driving device for engaging the continuous business forms assembly along a path of stationery travel to drive the same from the input end to the output end. Located forwardly of the drive means is a pinfeed device for engaging the assembly and forwardly of the pinfeed assembly is an adjustable drag device. The pinfeed device includes a non-positive drive that tends to drive the stationery along the path faster than the rate at which the stationery is driven by the drive means and, due to the effect of the drag device, operates in bucking relation therewith to produce smooth deleaving at all points in a deleaving run.

Abstract: A continuous form envelope assembly, wherein a plurality of superimposed plies define mailing envelopes with inserts, including return envelopes therein. Transverse lines of weakening across the plies define the individual envelopes. The return envelope, which is an insert, is defined by two plies, one of which includes a flap formation whereby the return envelope may be closed. The other ply defining the return envelope, includes a protective portion adjacent the flap and which is secured to the outer envelope so that when the return envelope is extracted from the outer envelope, the protective portion remains with the outer envelope.
