Automatic Thread Delivery (ATD) System

The patented and exclusive Baby Lock ATD System takes the hassle out of managing thread tensions during your overlocking.

All other brands of overlockers rely on a manual tension system to give you a balanced stitch. If you’ve ever used an overlocker you will know that tension adjustment is a nightmare – a complex ritual of dial adjustments is required to create a balanced stitch, and this needs to be performed every time you change fabric or thread. What a waste of time!

Baby Lock overlockers take the tension out of overlocking. The Automatic Thread Delivery (ATD) system delivers the required length of thread to form a balanced stitch, rather than putting tension on the thread itself. You simply select A, B, C or D depending on the stitch desired. No more Overlocking tensions.

Baby Lock introduced the ATD System in 1996. It was invented by Baby Lock founder Mr. Sakuma, who once again worked his magic, keeping Baby Lock at the forefront of the domestic overlocker market. The Automatic Thread Delivery System, in conjunction with cable sensors, delivers a balanced stitch on any fabric and with any type of thread. Changes can be made to fabric type without skipping stitches. 

The Automatic Thread Delivery System lays the thread on the fabric as each stitch is formed. The fabric is not responsible for pulling the threads through the tension discs as on other overlockers. Which means there’s no stress placed on the fabric, allowing it to flow under the foot without being stretched or damaged. This allows you to sew from delicate tissue or silk chiffon through to lycra and layers of denim or fleecy without having to make any adjustments to the machine settings.
