  • Patent number: 10525687
    Abstract: A tandem system of metering and donor rolls is used to apply two different adhesives to a fully adhesive backed multilayer sheet to produce variably distributed adhesives and properties. Each of the two adhesives is unique and is cured differently to create a layer of adhesive that has differing adhesive properties on the sheet. A clear adhesive is applied to a top portion of cards before they are cut from the sheet and has a higher tackiness than the adhesive applied to the rest of the cards on the sheet in order to reduce glue buildup on blades cutting the cards from the sheet.

  • Publication number: 20040079248
    Abstract: Both Laser printers and Inkjet printers have undergone many improvements in the last 10 years—mainly becoming faster and with better resolutions, and with prices going down all he time. However, one of the biggest limitations of all these types of printers has remained the same all the time: They print just on one side of the page. Although some printers on the market have an optional additional unit for mechanically flipping pages over, these units are typically cumbersome, expensive, and require extra space. Also, with mechanical flipping there is a higher chance for various malfunctions. Being able to efficiently print on both sides of the page can have many advantages: Saving paper costs, saving trees, saving office space or home space, being able to double the printing speed, being able to easily print eBooks, and more.
