When premanufactoring padded upholstery parts an especially high degree of rationalization is achieved by ruffling, joining and trimming done in one operation. The engineered sewing station 550-12-24 with solid edge trimmer allows the simultaneous and accurate execution of the ruffling processes as well as the precise trimming of the overhanging fleece fabric to ensure a trouble-free further processing, even in case of voluminous filling materials and intensive ruffling. Outstanding performance parameters, programmability, appropriate additional functions and basic adjustments as well as optional equipment improving performance and quality guarantee maximum flexibility and availability for the entire range of materials and applications.
