Description

Technical Field

[0002] A fabric stacking machine is a type of fabric stacking equipment used for folding and counting fabric. After stacking, the fabric is cut to size. Typically, 1 yard of fabric stacking machine is equal to 0.9144 meters. Some export fabric orders have requirements for the stacking length, such as requiring the fabric to be 6 yards long. After the fabric stacking machine reaches the required length, it is cut, and then manually folded from both sides to the middle once to form a piece of fabric with a width of one-third yard. Then it is packaged and shipped abroad for direct sale.
