Currently available corrugated carton sealing machines utilize a pair of taping heads, each of which carries a roll of pressure sensitive tape. When a roll of tape is finished, it is necessary to stop the machine and replace the roll with a resulting loss in production time. A simple solution to the problem is provided by the tape splicing device described herein which includes a bracket for mounting on a sealing machine frame, a shaft rotatably mounted on the bracket, the bracket carrying a spindle on each end thereof for a roll of tape, a first handle and brake on one end of the shaft for releasably locking the arm in one position, and a second handle on the other end of the shaft for rotating the shaft and arm, a wiper roller and a separation roller mounted on the frame. A first roll of tape is dispensed from one spindle to a taping head, and a second, fresh roll of tape is placed on the other spindle. When the first roll of tape is almost completely dispensed, the brake is released and the arm is rotated to bring the second roll of tape into contact with the adhesive surface of the first roll. Continued rotation of the arm causes the first roll to wrap partially around the second roll, whereby a paper tab on the leading end of the second roll is attached to the first roll of tape to start dispensing of the second roll of tape in overlapping relationship with the trailing end of the first roll of tape. The arm is rotated until the used roll passes between the wiper and separation rollers, whereby the trailing end of the used roll engages the separation roll and the new roll engages the wiper roll. The arm is again locked in position and the trailing end of the old roll of tape is cut. The resulting flap of old roll tape is pressed against the new roll to complete the splice and dispensed with the new roll tape to the taping head.
