FEBA manufactures and designs a wide variety of laminating systems to suit the customer specific needs and application(s). This particular laminator was built for a company producing sound dampening materials for the aerospace industries. The process involved the unwinding of a jumbo roll of a special cast silicone rubber with a paper liner. The paper liner was removed during the unwind stage. A loop tension control device was added becuase the material needed time (30 seconds) to relax prior to the application of the adhesive. This same technology is employed for companies producing soft foams or similar materials when stretch or curl is an issue. Once the proper tension was acheived, a PSA was first kiss-slit and then applied to the bottom of the rubber and an adhesive web--netting was applied to the top. The web adhesive was activated by three IR lamps (0-700 Degrees F) attached to automatic pneumatic pistons which moved up/down when cycle stop/start was actuated. After the web adhesive was activated, a roll of 1/2" foam was immediately laminated to the top of the rubber based product. The lower rewind removed a section of the kiss-slit paper liner from the PSA exposing the adhesive for the next product to be applied. The final lower unwind contained a felt material which was administered to the bottom of the rubber, completing the composite. The last upper unwind affixed an additional PSA to the 1/2" foam. After the lamination was completed a heavey duty scissor cut slitting unit slit the material to the appropriate width. The completed, slit product was then rewound to the appropriate length. This is just one example of what this system was designed to process. There were multiple applications invloved when the system was originally engineered.
Below are the main mechanical components of this custom laminating system:
