The bernette b42 Funlock is a dedicated 4-thread, 3-needle coverstitch machine built for professional hems, edges, and cuffs. With 3 coverstitch widths (2.8mm and 5.6mm) plus a chain stitch, the b42 delivers clean, stretchy finishes on even the most delicate knits and highly elastic fabrics. Colour-coded threading paths, a separate needle threader, and looper threading mechanism make setup straightforward, while the differential feed — adjustable while sewing — ensures smooth, even results every time.
