The KS-335A is a cylinder-bed compound feed lockstitch sewing machine that allows you to easily sew tubular items that would be more difficult to sew on flat-bed machines. You can fit cuffs, shoes, bags, hats, and more into this machine’s narrow cylindrical arm and sew stitches in challenging areas. In addition to the cylindrical arm, this machine has a walking foot that makes sewing thick items or multiple layers of fabric easier than ever. A walking foot moves in unison with the feed dogs to grip the fabric and pull it evenly through the machine. This feature makes the KS-335A perfect for sewing multiple layers because it prevents the layers from shifting and creating distorted stitches and puckering. Along with a walking foot, this machine has a presser foot height of 13 mm, which allows you to sew the bulkiest and thickest of items. When it comes to stitching, the KS-335A has an adjustable stitch length between 1 and 6 mm and a reverse stitching feature so you can sew backward. And finally, to save you time and money, the KS-335A has a semi-automatic lubrication system and a large bobbin capacity. A larger bobbin capacity means you don’t have to replace your bobbins as often.
