The quiet running of the low-vibration machines is one of the outstanding fea-tures. The built-in drive unit, transmits the power directly (direct drive) to the machine and guarantees a 50% reduction of the power consumption compared to conventional drive units. The machine works with very low thread tension settings. The needle bar stroke can be changed from 30 to 36 mm, which is an absolute requirement for sew- ing an extremely wide range of materials. The 300 mm arm clearance of the 2081/2083 series is unique for a high-speed seamer.
