716,127. Manifolding-webs. WILKES, J. July 28. 1952 [July 28, 1951], No. 17932/51. Class 16 Continuous stationery forming connected sets of business forms comprise copy sheets 1 divided by a line of perforations 3 or otherwise weakened line and having a second line of perforations 4 or other weakened 1 i n e arranged parallel to, and at a distance from, the perforations 3 thus leaving a transverse strip 5 between the perforations, and a carbon or other transfer sheet 2 weakened by a line of perforations opposite to those 3, in the copy sheets which is interleaved between the sheets 1, the sets of sheets being secured together by an adhesive applied to the strips 5. Round, elongated or other shaped holes 6 are formed in the carbon sheet 2 opposite to the strips 5 so that adhesive applied to one of the strips 5 secures two copy sheets 1 and the interleaving carbon sheet 2 together. The superposed webs may be folded along the line 3 into zig-zag formation and the perforations 3 form a weaker line than those 4 to enable a set of forms to be detached together. A semi-circular cut 7 in the carbon sheet 2 forms a notch at the bottom of a detached set so that by gripping the sheets 1 by the finger and thumb the individual sheets -1 are separated along the line 4 whilst the carbon sheet 2 remains attached to the strips 5. Any number of sheets 1 may be superimposed with carbon sheets 2 therebetween and the sheets 1 alone or together with the carbon sheets 2 may have sprockets engaging holes at the sides. In a modification, the carbon sheet has portions which are not treated with carbon and the carbon sheet is fixed by an adhesive on each side of those portions between copy sheets and between the lines of perforations forming the transverse connecting strip.
