Abstract
A method of printing and assembling carbonless, multi-sheet business forms from a plurality of cut sheets is disclosed which includes the steps of, for each form: a) applying a heat and/or pressure sensitive adhesive strip to a lower surface of a first sheet and an upper surface of a second sheet, the adhesive strips on the first and second sheets being in substantial vertical alignment when the first and second sheets are in overlying relationship; b) providing at least one intermediate sheet, the intermediate sheet having a plurality of apertures therein; c) passing the first, second and intermediate sheet through a non-impact printer; d) collating the first, second and intermediate sheet in overlying relationship so as to provide an individual collated form with the adhesive strips and plurality of apertures in alignment; and e) passing the collated form through a heat and/or pressure sealing device to thereby activate the heat and/or pressure sensitive adhesive strips by mutual contact through the plurality of apertures. Multi-part carbonless business form sets collated from cut sheets following the above described process are also enclosed in two, three, four and five part form assemblies.
