STB-50 is suitable for wire harness winding after intermediate splice crimping and normal bundling of wires. Adopting a winding structure with a roll diameter of 90mm and a brush width of 57mm, it can meet the processing needs of a wide range of tape widths and wire harness diameters. With copper wheel feeding, the structure is stable and reliable and the operation is simple and convenient, which can significantly reduce the labor intensity of workers.
