A blow box apparatus is disposed within a pocket defined between an upstream and a downstream dryer and a transfer roll. The blow box apparatus includes an elongate box which defines an enclosure in which the first and the second ends of the enclosure are connected to a source of pressurized air. A first end wall has a proximal and a distal end and a first and a second edge. The proximal end is secured to the first end of the enclosure and the distal end is disposed adjacent to the transfer roll. The first edge is disposed adjacent to the upstream dryer and the second edge is disposed adjacent to the downstream dryer. A baffle is disposed between the end walls such that during a threading operation, a tail of the web is guided around the upstream dryer and around a threading chamber of the transfer roll.
