Tape cutter protective guard means for carton sealing machine tape applying mechanism

摘要

Tape applying mechanism assembly for a carton sealing machine, which includes a movable tape cut-off means or cutter having a cutting edge and guard means protectively covering this cutting edge when the cut-off means is in a projecting idle position. A movable carrier supports tape wipe-on means in a path of advance of a carton when the assembly is mounted in the machine and it is retractable by such carton advance. Additional movable carrier means supports the cutter for motion of its cutting edge across a path of travel of the tape to the advancing carton for severance of the tape as the section of the latter of desired length is applied to the carton. Retractable guard means protectively covers the cutting edge when the cutter is in a projecting idle position intervening successive tape applying actions. Means retract the guard means for uncovering the cutting edge while the carton advances past the tape wipe-on means.
