    1-5 principles of operation the hd-25 “workhorse” laminators operate by pulling film with a thermally activated adhesive over a heat source and into a set of laminating rollers. Film from the supply rolls passes over heat shoes to activate a polyethylene adhesive layer on the film. It then passes th...

    1-6 laminating film most thermal laminating film consists of two layers: a base of polyester and an adhesive layer of polyethylene. The polyester layer forms the harder outer surface of the film and does not melt at laminating temperature. It provides rigidity and protection for your laminated items...

    5-2 threading the laminator 1. Although this machine can be threaded cold, most operators feel it’s easier to thread while it is warming up or already hot. Remove the supply roll mandrels and the feed tray. The supply roll mandrels are now ready to be loaded with film. The film is usually wound with...

    3. Review the threading diagram remember, the shiny side of the film must always go against the shoe. The dull (adhesive) side must face away from the shoe. With the top roll of film centered on the mandrel and the shiny side facing down, pass the film under the lower idler, over the top idler, and ...

    Make sure the film is threaded properly. The most frequent operator error is threading the film under the bottom stabilizer bar instead of under the bottom idler bar. The threaded film should not touch the bottom stabilizer bar. When the bottom web of film is threaded around the stabilizer bar inste...

    Sometimes you may see film detach from an item along one edge (the edge that was put in first). This happens when the material is put all the way into the nip before the machine is started. The area of film between the shoes and the nip can cool off too much while the machine is idle. The adhesive m...

    To minimize squealing run the laminator with the least amount of supply roll tension that will do the job of removing wrinkles from the web of film. Make sure you are not using a higher temperature than needed and clean the heat shoes periodically (see section 6-3). If the noise gets really objectio...

    Problem: general haziness or cloudiness in the film after lamination. Solution: increase the temperature. The cloudiness is a function of incomplete adhesion. On a variable speed machine loaded with thicker film it may be that the film is being run too fast and is not getting enough time on the heat...
