Chinese manufacturers offer various "double layer wrapping machines," primarily for cable/wire taping (using mica, foil, etc., for fire resistance/strength) and for food/confectionery (like chocolates, candies, soaps, using paper/film for a layered look). These machines range from high-speed, PLC-controlled industrial models for cables (e.g., Dongguan Wirecan, Newtopp) to automatic folding machines for sweets (e.g., Shengli Machinery). Key features often include servo motors for precision, PLC control, and automation for consistent tension and output.
