ZF-330 envelope machine has both Chinese and Western usages. Paper feed parts employ the structure of bottom air-suction paper extraction, while air-suction transport avoids double-feed phenomena. Automatic four-edge indentation increases precision and reduces errors. Horizontal fold-parts use roller air suction. Paper jam decreases and paper bags can go through the fence smoothly. Traditional system employs bearing, synchronous wheel and timing belt to cut the noise.
