A web of sheet material has a plurality of longitudinal rows of indicia patterns printed on a front face thereon, with the indicia patterns all aligned on the web in common readability orientation. On its back face, the web has a plurality of longitudinally disposed patterns of repositionable pressure sensitive adhesive thereon, with the adhesive patterns being oriented in registration with the rows of indicia patterns. Longitudinal severing of the web thus results in a plurality of identical web strips. Lateral severing of the web strips results in a plurality of identical note sheets, each note sheet bearing one of the indicia patterns on its front face and a pattern of repositionable pressure sensitive adhesive on its back face. The note sheets are applied in registration to an advertising piece to create a promotional assembly. In this process, unique intermediate rolls of the web and web strips are developed. The web strips are provided in linerless form, or may be carried on a liner sheet for further processing and application to an advertising piece.

Repositionable note sheets and method of formation thereof

Sheets to be coated with water-based coating material, for example a primer and a low adhesion backsize, are supplied from a feeder (1), in end-to-end overlapping relationship, to a dual coater (3) in which the sheets are coated individually on both sides. A sheet inserter (2) is provided, upstream of the dual coater, to insert sheets from a second supply into the sheets from the feeder (1). The dual coated sheets are dried as individual sheets or as a pseudo-web of overlapped sheets, The sheets are then overlapped, unless previously overlapped, and the direction of overlap changed, if necessary, to provide the trailing edge of each sheet on top of the leading edge of each succeeding sheet. The overlapped sheets are conveyed through an adhesive transfer station (7) where stripes (236) of at least partially dried adhesive are coated onto the dual coated sheets from a transfer belt (71).
