To form an adhesive layer at an accurate position by providing a marking unit, a marking detecting means and an adhesive coating unit between a raw fabric unwinding unit of a bookbinding backbone base material sheet and a base material winding unit after coating with the adhesive.

In the apparatus for manufacturing a bookbinding tape used for a bookbinding unit, a marking detecting means 351 is disposed at a position separate by (m) from a coating nozzle 353 of an adhesive coating unit 352, and a marking hole opened at a tape base material by a rotary die cutter 350 is detected by a sensor provided thereat. A solenoid valve of the nozzle 353 is opened after a preset delay time according to a tape size to be manufactured from when its detection signal is input, the base material is started to be coated with an adhesive, and the valve is closed after a predetermined time corresponding to the size is elapsed. After the tape intermittently coated with the adhesive is cooled by a cooler, it is divided into a plurality of tapes by a slitter 356, and contained in a winding reel 357.
