With excellent performance and high output, this model is Acer's most successful and largest-selling product. The newly designed sinker creates the perfect loop shape with the concept of consistent looping force and precise ground yarn and loop turning points. In addition, there are a variety of sinkers with different ring heights to choose from. This machine is suitable for velvet, mesh velvet structure, pressed velvet, all 2-rail bead floor velvet. A shear loss of less than 15% causes the main ring to form a V-shape (sharp corner) and further reduces the loss of grip, shear, and brushing.
