A multi-roll automatic tape splicing device includes a platen which is rotatably mounted on a support frame via a shaft. Two or more tape mandrels are rotatably disposed on the platen at a substantially equal distance from the shaft, and substantially equally spaced from each other, each mandrel being capable of receiving a respective roll of tape. An index drive is operatively coupled to the platen, for selectively rotating the platen so as to successively move each mandrel into a predetermined operating position at which a web of tape can be drawn from a respective roll of tape disposed on the mandrel, and for moving a mandrel out of the operating position when the respective roll of tape is depleted. A first sensor is operatively mounted on the support frame and capable of detecting a depleted condition of a roll of tape mounted on a respective mandrel in the operating position. A second sensor is operatively mounted on the support frame and capable of detecting rotation of a mandrel in the operating position. A cutting unit is disposed on the frame and capable of severing a web of tape being drawn from a depleted roll of tape. A control unit is responsive to the first and second sensors such that when the first sensor detects a depleted condition of a roll of tape, the control unit controls the index drive to rotate the platen and thereby move the next successive mandrel into the operation position. A tab formed on the end of a fresh roll of tape mounted on the successive mandrel adheres to the web of tape being drawn from the depleted roll, thereby causing a web of tape to be drawn from the fresh roll. Thereafter, the control unit controls the cutting unit to cut the web of tape being drawn from the depleted roll, when the second sensor detects rotation of the mandrel in the operation position.
