The machines of the subclass “SENSITIVE” have exactly been designed for these sensitive applications. Technically, these machines are different due to the PTFE-coated throat plates, hook covers, and attachment slides enabling a trouble-free material feed during the sewing process, even when working with difficult-to-feed materials like fine leather. In order to guarantee a constant hook thread tension from the full to the empty bobbin, the innovative CTB bobbins are used as standard. On the upper side, these extremely light and high-strength bobbins are equipped with an inspection window for the optical control of the bobbin thread capacity. On the underside, cylindrical braking, and lifting spring dramatically reduces the overspending of the bobbin and facilitates the bobbin change for the operator. The specially adapted sewing kinematics with reduced needle bar stroke guarantees a perfect stitch formation in fine materials. Apart from the thread trimming system also an electro-pneumatic sewing foot lift and automatic back tacking belong to the basic equipment of all subclasses.
