ABSTRACT:
A knife blade guard locking mechanism, for use in conjunction with the sealing tape application rollers of a tape cartridge assembly of a case sealing machine, is adapted to be operatively connected to a spring biasing mechanism of the sealing tape application rollers such that when the sealing tape application rollers are disposed at their inoperative positions, the knife blade guard locking mechanism is disposed at its locked position so as to effectively cover the knife blade in order to protect personnel from being accidentally cut. Conversely, when the sealing tape application rollers are disposed at their operative positions, the knife blade guard locking mechanism is automatically unlocked so as to permit the knife blade to be uncovered in order to perform its sealing tape cutting operation.
