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 pl

Abstract: A multi-part carbonless business form includes a first upper CB sheet having a first heat and/or pressure sensitive adhesive strip or a lower surface thereof and extending along and adjacent one marginal edge thereof; a second lower CE sheet having a second heat and/or pressure sensitive adhesive strip of substantially identical adhesive composition as the first strip, on an upper surface thereof and extending along and adjacent a corresponding marginal edge in substantial vertical alignment with the first adhesive strip; and at least one intermediate CFB sheet located between the first upper sheet and the second lower sheet and having a first plurality of apertures vertically aligned with the first and second adhesive strips to thereby allow heat and/or pressure sealing engagement between the upper CB sheet and the lower CF sheet through the first plurality of apertures in the intermediate CFB sheet.

Abstract: In a method for producing composite carbonless copy business forms using non-impact printers, a CFB web having segmented glue lines across the width of both sides of the web. These glue lines adhere the CFB web to adjacent upper and lower CB and CF webs to seal together a business form. The glue lines on both sides of the CFB web are segmented such that the adhesive on the front of the web is laterally staggered from the adhesive on the back of the web. The staggering of the glue line ensures that the adhesive on the front of the web does not adhere to the adhesive on the back when the web is in a roll. Alternatively, the glue line on the CFB web is replaced with a line of holes that align with the glue lines on the CF and CB webs when the webs are registered together.

Abstract: Utilizing just five different types of sheets, multipart carbonless business forms may be printed with non-impact printers and then assembled together without using line hole punched sheets and intermediate parts. The CB sheets have an adhesive strip (continuous or discontinuous) on the CB face spaced a first distance from a sheet edge. There are first and second CF sheets, the first CF sheets having an adhesive strip (preferably linear, and continuous or discontinuous) on the CF face spaced a first distance from an edge, and the second CF sheets having an adhesive strip on the CF face thereof spaced a second distance from the edge. First and second CFB sheets are provided, the first CFB sheets having an adhesive strip on the CF face spaced the first distance, and an adhesive line on the CB face spaced the second distance; and the second CFB sheets having the adhesive strips vice-versa. The sheets are fed, in order, from trays of a non-impact (e.g.

Abstract: Record material useful for carbonless copying systems and the like and adapted to develop distinctive coloration on contact with a preferably colorless dye precursor reactive in an electron donor-acceptor color-producing mechanism, characterized by a thin, uniform surface coating containing smectite clay having its molecular structure chemically modified to impart substantially Newtonian viscosity behavior to aqueous suspensions thereof. On examination by X-ray diffraction, the chemically modified clay preferably exhibits a discernible peak at a characteristic angle of diffraction. Chemical modification is preferably achieved by contacting the clay with the acid, such as sulfuric acid, for a time sufficient to irreversibly alter the clay structure. Such clay coatings can be applied by the usual coating techniques and produce dye images of substantially improved resistance to fading by light and ordinary atmosphere.
