The bernette 48 is the top model in the Funlock series and is a combination of an overlock and a coverstitch machine. It offers a total of 23 stitches: 15 overlock stitches, 3 coverstitches, 4 combo stitches and 1 chain stitch, the overlock stitches with a stitch width of up to 7 mm. The threading is facilitated by colorcoded threading paths, and a manual threader supports the threading of the needle eye. The looper threads are threaded mechanically. The knife is operated from below and thus provides not only a clean cutting edge but also safe handling and good visibility to the stitching. The b48 Funlock sews at a speed of up to 1,300 stitches per minute.
