The present invention relates to a feeding and tension unit for a band to package a box, and a banding apparatus including the feeding and tension unit. The feeding and tension unit supplies a band to package the box in a forward direction or pulls the band in a reverse direction to apply tension. The feeding and tension unit comprises: a feeding roller unit which includes a fixated feeding roller and a pressing feeding roller, supplying the band into a space between the fixated feeding roller and the pressing feeding roller; a tension roller unit which includes a fixated tension roller and a pressing tension roller, pulling the band between the fixated tension roller and the pressing tension roller; a feeding driving motor, one end of which is connected to the fixated feeding roller to transfer forward a rotational force; a feeding link unit which moves the pressing feeding roller using at least one feeding link, to control feeding; and a tension link unit which moves the pressing tension roller using at least one tension link, to control tension, wherein an other feeding driving motor is connected to the fixated tension roller to transfer a reverse rotational force. |
