This was the birth of the Baby Lock brand, the first home overlock machine on the market.
But the innovation didn't stop there. In the decades that followed Baby Lock engineers proceeded to invent other revolutionary features, such as the unique jet-air thread system and the automatic thread delivery system.
Today, there is a generation of Baby Lock home sergers that don't require any tension adjustment and are able to be threaded effortlessly. Users of these machines can also forget all the trouble connected with setting the "perfect" tension and the confusion about which tension dial should be turned, something that was unimaginable at the genesis of the company.
