Definitions

  • the present invention relates to methods for forming sheets or strips having coatings of repositionable pressure sensitive adhesive that releasably adhere the sheets together in the pad or the strips in a roll, which sheets or strips have indicia on one major surface; to master stacks from which pads are cut; and to methods for forming such master stacks, pads or rolls.
  • Pads of sheets are known in (e.g. EP-A-0 261 817) which the sheets have coatings of repositionable pressure sensitive adhesive on one major surface that releasably adhere the sheets together in the pad, and the sheets have indicia on their major surfaces opposite the coatings of adhesive that may include, for example, graphics, pictures, designs, or alpha numeric information including printed words or numbers.
  • One conventional method that has been used for making such pads includes the steps of (1) providing a printing press capable of printing indicia along a web or length of sheet material passed through the press utilizing printing plates mounted on the press; (2) passing a web or length of sheet material having a coating of repositionable pressure sensitive adhesive along a first side surface through the printing press to print the side surface of the length of sheet material opposite the coating of repositionable pressure sensitive adhesive with the indicia; and (3) converting the printed web or length of sheet material into a plurality of pads with portions of the coating of repositionable pressure sensitive adhesive on the sheets releasably adhering the sheets together in the pads and with the sheets in the pad having indicia on the various sheets in the pad.
  • the converting step in this method is typically performed by (1) cutting the printed length of sheet material into parts of a predetermined size; (2) stacking the parts together to form a master stack; and (3) cutting the master stack into portions to form the plurality of pads.
  • Pads have been made using the method described above in which the coating of repositionable pressure sensitive adhesive on each of the sheets is in a band on one of its major surfaces adjacent one of its edges with the sheet being free of adhesive on that major surface adjacent its opposite edge, and the sheets are stacked either (1) with the adhesive coating on each successive sheet in the pad being disposed along alternate opposite sides of the pad, or (2) with the bands of adhesive coating on the sheets in the stack disposed along the same side of the pad.

  • Such a method provides several significant advantages over prior art methods. It allows the easy manufacture of pads in which at least a portion of the indicia on some sheets in the pad is different from the indicia on other sheets in the pad which, for example, would allow certain sheets in the pads to be calendars for different months or weeks or days, and could provide different massages or blank sheets between such calendar sheets, or would allow different sheets to bear a different pictures (e.g., sequential cartoons or sequential pictures or other images that are sufficiently different to provide the illusion of motion by sequentially bending back and releasing portions of the sheets on which the pictures are printed, which cartoons, pictures or images could be all at one location or change locations on the sheet to provide, for example, the illusion of a person walking across the sheet) or different messages which may be in an infinite variety of different type sizes, styles, weights or widths, such as different sayings or religious messages (i.e., different Bible quotations or prayers), or different advertisements for different ones of a manufacturers products which may include different logos or other corporate or commercial marks such as brand names
  • a pad comprising a plurality of sheets of the types described above which have indicia on their major surfaces, or a master stack from which such pads can be cut, or rolled strips having indicia on their major surfaces, at least portions of which indicia on each master stack, pad or rolled strip varies in a non repetitive pattern on the various sheets in the pad or master stack or along the strips.
