Intelligent fabric handling
Support where the fabric changes.
The Urus system senses changes at fabric joins and coordinates presser-foot pressure with feeding force. It helps the machine transition between thinner sections and thicker cross-seams, supporting an even finish through changing layers.
Control that suits your work
Choose manual, semi-automatic or automatic sewing modes. Adjustable sewing speed and needle-stop positioning let you balance production pace with control, while the front-mounted tension dials keep thread adjustment accessible.
For everyday garment production
A practical choice for T-shirts, knit garments, general clothing, alterations and woven-fabric edge finishing. Differential feed helps manage fabric stretch or gathering. Match the needle, thread and settings to your fabric, and test a sample before production.
