In the midst of transferring a cord fabric transferred to a calender apparatus, weft is finely divided by passing the cord fabric through weft dividing means, thereafter, a plurality of blades arranged movably in a width direction on an upper face side of the cord fabric are reciprocally moved in the width direction over an entire width thereof to be brought into contact with the cord fabric, and the divided weft piece is wiped off to remove by respectively striking respective cords of the cord fabric by the respective blades.
