Recently the Double E Company worked with a producer of large-format digital graphics who specializes in large scale banners and billboards. The company had a situation where they needed a way to manufacture a welded pocket seam in the film material before it went to print. They were trying to unwind a 5" film strip, fold it in half and weld the edges together. The process they were using proved unsuccessful so they asked Double E to engineer a small tension controlled unwind station that could be easily mounted to the production line.

 

Double E's solution featured a narrow web device consisting of an SR-2000 strip chuck mounted on a safety chuck body and regulated with a Re Eleflex electromagnetic powder brake. This narrow web station combined with the Re CF.85 load cell, tension roller and integrated tension control system with a T.1 controller provided the solution for regulating the tension during the unwind process. The customer was now able to provide a consistent method for welding the pocket seam.

The success of the initial narrow web station prompted the customer to order four more units for each of the production lines.
