Sewing machine offers increased thread tension

How can I…Improve the stitching of heavy-weight fabrics with heavy thread tension?
Here’s how: The AMS-210EN-HL1306/7300 sewing machine with a unique active tension mechanism and a slide-type takeup system increases the maximum tension by 50 percent, compared to standard models, for improved overall seam quality and sewing performance.
Especially for: Sewing seat belts, container belts and bags.
