105" (2667 mm) Lamination Line
109 inch 2769 mm roll face laminating machine with a 105 inch 2667 mm working face, configured for wet bond application, and equipped with dual unwinds each with flying splice capability to ensure continuous operation, and a completed wound roll diameter of 48 inches. Tension controls are configured to handle low tension with lightweight films and high tension on foil webs. One unwind is capable of paper web handling.
The unwind web paths are equipped with variable bow spreader rolls to handle film and paper. The film web path is equipped with a corona treater to ensure optimal dyne level and bond strength. All webs are equipped with web guides. The machine is equipped with laminating nips capable of over 13,000 psi. This configuration is utilized for two-component lamination. This configuration is utilized for two-component lamination.
Drying is achieved with 3 oil heated drums with temperature capability up to 400 degrees F. The drums are each wrapped with Global Tech high velocity air caps. The ability to control temperature of dryer drums, air cap, and air velocity, provides a fine degree of control over evaporation rates as required by various products.
Machine Speed will be dependent upon product, adhesive applied and its solids, and whether or not reinforcing scrim is incorporated into the product and it may range from 200 ft/min (61 m/min) to 1000 ft/min (305 m/min).
The machine is also equipped with a reinforcing scrim weaving capability. Machine Direction and diagonal patterns are achievable with a variable angle capability. Winona is currently set up for fiberglass and polyester yarn combinations.
