724,823. Manifolding stationery. BURGMER, J. March 27, 1953 [March 31, 1952; April 18, 1952], No. 8580/53. Class 16. A continuous series of duplicating sets or the like in which each set consists of a plurality of alternately arranged typing and carbon sheets, has at least the top and bottom sheets 4, 1 connected to one another by detachable securing strips 9, 10 provided at the longitudinal edges so as to enclose the middle sheets, such as 5, 6, 14, and carbon sheets 7 of the sets and the top and/or bottom sheets 4, 1 form part of a continuous paper web while the remaining sheets are spaced, at 8, at their transverse edges from the corresponding sheets of the adjoining sets. Three sets of forms a, b, c are shown with the bottom sheet 1 continuous but with perforations 3 between the sets in the spaces 8. The securing strips 9, 10 are both on sheets 1 and 4 but, as shown, the strip 9 is omitted from the typing sheets and the strip 10 from the carbon sheets, and the strips 9, 10 are joined to the typing sheets with a line of perforations 11, but no perforations are provided between strips 9 and the carbon sheets 7, so that the carbons are removed with the strips 9. In alternative constructions, the strips 9, 10 may be on all sheets, the inking on the carbon sheets 7 being omitted, or on none of the inner sheets, which are then maintained in position solely by the outer sheets 1, 4. The sheets are connected together along the strips 9, 10 by gumming. The sets of forms can be rolled up or folded in zig-zag arrangement. The perforations 11 near the head of each set of forms may be small length cut-outs with longer cut-outs for the rest of the form, so that detachment of the head requires greater force and is less likely to occur inadvertently on insertion in a typewriter or like machine.
