The Swedish Textile Machinery Association (TMAS), ACG Kinna and ACG Nyström collaborated with Juki Corporation, a sewing machine manufacturer, in the development of a new automated line concept to speed up the production of finished filter bags. The SFL-2000 line is a four-year development project between the companies. It is suited for a wide range of filter media and can produce quality and accurate seams to pre-defined parameters with optional modules allowing for customized constructions.
The line is available in three versions — the SFL-2000S for sewn seams, the SFL-2000-W for welded alternatives and the SFL-2000WS employing both joining technologies. The standard version has a single media roll feeder with the option to add a second, with a Juki MO-6903G overlock head joining two separate materials together in continuous production. A custom pre-folding system creates the tubular form of the filter bag and the overlap just prior to the Juki sewing and welding units. The bag is then conveyed to the cutting and printing unit.
