Baby Lock

Baby Lock is a sewing machine brand specializing in sergers, sewing, embroidery, and quilting machines, known for innovations like air threading and automatic thread delivery that make traditionally difficult machines genuinely easy to use.

The Baby Lock story starts in 1956 in Japan, when engineer Koichi Sakuma built a wooden prototype of a small overlock machine. His wife worked as a seamstress, and he wanted to give home sewers the kind of edge-finishing capability that until then only existed on industrial machines. After years of refinement, the first functional prototype was completed in 1963.
In 1964, a group of engineers (working at what some sources identify as Juki) pitched the idea of a compact home overlock to their employer. When management declined to build it, the team left and formed their own company to bring the concept to market. The first production home serger, the EF-205, launched in 1968. Because it was small compared to industrial overlocks of the era, it picked up the nickname "baby" lock, and the brand name stuck. In 2023, the Japan National Museum of Nature and Science recognized the EF-205 as a historically significant product for shifting the industry's definition of what counted as a household sewing machine.
Baby Lock machines have been manufactured in Yamagata, Japan by Suzuki Manufacturing Co., Ltd. since 1968. (Some product lines outside the core overlocker family are produced by partner factories.)
Tacony and the U.S. market
In 1946, Nick Tacony invested his savings into used sewing machines and parts and started a wholesale and service business out of his basement in St. Louis. Through the 1950s and 60s, he built Tacony Corporation into a national sewing machine distribution network. In the early 1970s, Tacony picked up Baby Lock and brought the brand to North American dealers. Tacony remains family-owned and is the exclusive U.S. distributor for Baby Lock today.
Key innovations

1968: EF-205, the world's first home serger.
1993: Jet-Air threading system, which threads loopers with a puff of compressed air. It was the first sewing machine technology to win Japan's Invention Grand Prix.
1997: Automatic Thread Delivery (ATD) debuted on the Imagine, the first serger that does not require tension adjustment. The machine measures and delivers the exact amount of thread per stitch rather than relying on tension dials.
2001: First standalone cover stitch machine.
Ongoing development across sewing, embroidery, quilting, and longarm machines, including the Solaris flagship.

Why customers buy Baby Lock
Baby Lock built its reputation on solving the two things every serger owner historically hated: threading and tension. Jet-Air threading and ATD turn what used to be a 20-minute setup into a few seconds of work, which is why Baby Lock dominates the home serger category. Machines are sold only through authorized independent dealers, and the brand has roughly 600 dealer locations across North America.
