In a booklet back sizing apparatus in which the glue adhered to the drum is applied to the back surface of the booklet, an air outlet for blowing air escaping upward from the upper part of the sizing drum and across the upper layer facing the opening surface of the glue container. And a suction duct for blowing air from the outlet and sucking the air traversing the upper layer, and a circulation duct for sending air to the outlet through a deodorizing filter and a circulator through the air sucked from the suction port. It is characterized by the following.

According to this feature, odor and smoke generated by heating and melting the glue formed of the hot melt type adhesive flow along the air flowing across the upper layer of the opening surface of the glue container blown out from the air outlet, It is sucked from the suction port and taken into the circulation duct. Smell and smoke taken into the circulation duct are removed by a deodorizing filter, and the air after removal is sent to an air outlet by a circulator and blown out. Therefore, the smell and smoke generated by heating and melting the glue made of hot melt adhesive are blocked by the air flowing across the upper layer, and are removed by the deodorizing filter. it can. Further, the air blown out by the circulation of air is heated by receiving the heat of the glue, keeping the upper part of the glue container warm, and applying the heat to the sheet bundle to improve the permeability of the glue.
