Curtain cutting and stitching entails the sequential processes of cutting and sewing curtains. For cutting, tools such as ultrasonic cutters or vibrating knives are used to ensure clean edges and accurate sizing of the curtain fabric panels. Stitching includes the use of multi-needle sewing systems that join, hem, or add decorative stitches to the fabric panels. When these processes are intergrated, there is molaerial movement and time delays, resulting in lower efficiency. Advanced machines that combine both cutting and stitching increase efficiency by automating these processes.
