With the launch of the 7 Series, BERNINA presents a world’s first, the BERNINA 9 Hook (B 9 Hook). Combining the two best hook technologies, the B 9 Hook is patent pending. The new heart of the BERNINA machine features a novel, centrally-placed driver, which allows the B 9 Hook to run steady and quiet. The B 9 Hook sews high-precision stitches up to 9 mm in width with speeds up to a 1,000 stitches per minute. And the bobbin has 80 percent more thread capacity than our standard bobbins, allowing you to sew longer without interruption. Finally, the B 9 Hook is made of high-quality materials that allow the thread to run smoothly with consistent tension.
