  • Page 10: Principles Of Operation

    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 through rubber rollers to apply pressure and bond the film to the item being laminated.

  • Page 11: Laminating Film

    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.

    4-1 SAFETY PRECAUTION DO NOT OPERATE THIS MACHINE UNTIL YOU HAVE READ AND FULLY UNDERSTOOD THE FOLLOWING SAFETY PRECAUTIONS. 1. Never operate this machine without reminding yourself that a big laminator is a powerful and potentially dangerous tool. If misused, used carelessly, or used without observing the rules of safe operation, very serious injury can result.

  • Page 21: Threading The Laminator

    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.
  • Page 22 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 then drape it over the top heat shoe.
  • Page 23 5. With both rolls threaded and installed in their respective brackets, unwind the top and bottom supply rolls about a half-turn each. This will provide enough slack in the web to allow the feed tray to slide on easily. 6. Slide the feed tray into position. Position the safety shield forward toward the heat shoe.

    5.3 SUPPLY ROLL TENSION OTHER ADJUSTMENTS 1. Now adjust the supply roll tension. First loosen all four supply roll tension knobs, then tighten them (turn clockwise) until they just begin to press on the springs. Another ¼ to ½ turns (one turn equals 360 degree rotation of the knob) of tension on all four knobs is usually sufficient for 1.5 or 3 mil film.

    5-4 LAMINATING 1. Turn on the power and the heaters. • Set the temperature. The small green output light will come on while the machine is warming up, approximately twenty minutes. • When the two heat indicators are at the desired temperature the machine is ready to laminate.
  • Page 27 2. During warm up the actual temperature will sometimes overshoot the set temperature by more than a few degrees. Then when lamination is begun the actual temperature may initially drop below the set temperature. Unless these temperature swings are extreme there is no cause for concern. The heat controllers each contain an intelligent processor which gauges the heat requirements of any job being run on the laminator.
  • Page 28 If the film curls up as it leaves the machine, loosen the top supply roll mandrel (turn counterclockwise) and/or tighten the bottom supply roll mandrel (turn clockwise). If the film curls down after it leaves the machine, tighten the top supply roll mandrel (turn clockwise) and/or loosen the bottom supply roll mandrel (turn counter-clockwise).

    5-6 SLITTER OPERATION 1. The slitters on the HD-25 can be moved independently from the sides of the machine even while lamination is in progress. The slitter heads are mounted on a steel bar with an adjusting knob on each knife holder. The slitters must be positioned manually.

  • Page 34: Simultaneous Laminating And Mounting

    5-7 Simultaneous Laminating and Mounting There are several different ways to simultaneously mount and laminate. The one preferred by most experienced users, especially those in digital imaging, is to hot laminate while mounting with a pressure-sensitive adhesive at the same time. Cut a piece of your pre-coated substrate (mounting board) slightly larger than your image.

  • Page 36: Cold Applications

    5-8 COLD APPLICATIONS Cold Mounting The Heavy Duty 25 is designed to be a cold laminator and mounting device as well as a hot laminator/mounter. There are many different methods and sequences for laminating and mounting but the most common procedure used with digital images is to first hot laminate and then cold mount.
  • Page 37 Peel back about two inches of the release liner on one end of the board. Use this exposed adhesive to position the laminated graphic on the board. Slide the positioned end of the board into the laminator holding the graphic up with one hand.
  • Page 38 “release” paper can be run under the whole process to keep exposed adhesive out of the nip while laminating a series of pieces. For those customers who need cold lamination exclusively, Ledco manufactures the Econocraft line of pressure-sensitive machines 25 to 50 inches wide.

  • Page 39: Preventing And Solving Problems

    5-9 PREVENTING AND SOLVING PROBLEMS Please read this section before you have a problem. PROBLEM: Wrinkling of the material as it goes into the laminating rollers. This problem usually occurs when laminating an item that has been folded, rolled, bent or wrinkled. SOLUTION: Make sure the leading edge of the item being laminated is laying flat and is inserted parallel to the laminating rollers.
  • Page 40 SOLUTIONS: Make sure you have enough supply roll tension to take the wrinkles out of the film before it gets past the heat shoes.
  • Page 41 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 instead of the idler bar the film will tend to wrinkle and often will not adhere.
  • Page 42 MISE EN GARDE: Si l’on appuie trop longtemps sur l’interrupteur de marche arriére, le film risque de s’enrouler dans l’autre sens. Appuyer par á-coups sur l’interrupteur et vérifier le résultat chaque fois. ADVERTENCIA: Apretar mucho tiempo el interruptor de marcha atrás puede causar bobinado inverso.

  • Page 45 start to fall off after a few days. The solution here is to run the work at a higher temperature (320° to 340 °F will usually do the job).
  • Page 46 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.
  • Page 47 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).
