Abstract: A tape applicator for applying tape to seal a case is disclosed wherein the pressure applied to the top of the case may be significantly reduced by activating an actuator at the appropriate time to lift the application mechanism or assembly and the cut-off mechanism away from the case being sealed.

Abstract: An improved tape applicator for apply a tape to close a case or box is provided that uses a wiper system that better seals the tape to the box, provides an improved cut-off system wherein the action of the cut-off blade which partially cuts and then tears the tape is across the tape path at an improved angle. Also included is an improved system for adjusting tab length on the lead end of the case, providing a stiffened free end portion of the tape to engage an on-coming case, for controlling the rotation of large tape rolls by applying pressure to the side of a large roll and locking the tape roll to the mounting hub on the machine by penetrating the tape roll core with locking elements.

Abstract: Tab length is controlled in a tape applicator by adjusting the position of a tension roll as the diameter or periphery of the tape supply roll is changed to increase the force pulling the tape from the supply roll as the diameter of the tape supply roll decreases without significantly changing the tension in the tape.

Abstract: A bottom tape applicator that facilitates changing of large diameter tape rolls is provided that is composed of a stationary frame mounted in the machine and through which a full roll of tape may be passed and that mounts a detachable unit that is replaced to replace the tape roll and a base unit movable between an open position and an operative position. The base unit combines with the detachable unit mounted in operative position in the stationary frame to form an operative tape applicator.

Abstract: In general, the present invention comprises of a control unit with a tape applicator with operative members to selectively actuate sensors of a multiple sensor arrangement each of which is positioned to detect movement or position caused by a carton or the dispensing tape; specifically, the signal caused by the present of the carton; the movement caused by the dispensing tape as the carton being taped, and a further signal actuated based on the size (depletion) of the dispensing tape roll. The detected signals from the sensors are sent to a control unit with a multiple timing circuit or a preprogrammed micro processor with predetermined sequences and time values to generate and emit a correspond alarm signal based on the following control logics.

Abstract: A tape applicator to apply tape onto a vertical face of a carton with the tape roll mounted for rotation on a horizontal axis and including a tape deforming device position on a tape path between the tape roll and the point of application of the tape to the carton. The tape deforming device twists the plane of the tape through 90° from horizontal when leaving the tape roll to vertical for application to the vertical face of the carton. The tape applicator can adjust the position of the tape at the point of application to the carton vertically.

Abstract: This invention relates to a tape applicator or tape head formed from a combination of two separated apparatuses namely a detachable unit containing a front portion of the tape applicator and a stationary unit containing a rear portion of the applicator with snap-on engagement there between to obtain the interactive motion of a conventional tape applicator i.e. the present invention separates a conventional tape applicator into two separate portions which results in the ability to quickly change tapes and reduces safety hazards.

Abstract: A commercial tape applicator capable of folding at least one side edge of a tape as it is fed to the applicator to provide an easily a gripped edge on the tape after it has been applied to the case. The invention provides a folding station on a dancer platform mounted on a dancer arm that has a nip roll at its free end and the arm is biased so that the nip roll is in contact with the periphery of a tape roll forming the source of tape and is usable to align the tape path through the folding station with the tape leaving the tape roll and accommodate deformation of the roll. A latch and cooperating cog wheel may be used to control the off feeding of the tape for the supply roll.

Abstract: An improved tape supply system particularly suited for use in a multifunction tape applicator for applying a front and/or back L-clips to a case wherein a dancer roll is operable to provide slack in the tape and a break is applied to facilitate cutting of the tape.

Abstract: A multifunction tape applicator for applying a section or sections of pressure sensitive adhesive tape to a carton selectively in different carton sealing configurations, namely C-clip; single L-clip, front and back L-clips and sectional skip-gap taping. The multifunction tape applicator comprises a basic tape applicator unit to apply a common C-clip tape from a tape roll with built-in design apparatus for tape applying, tape cutting, tape tension control to facilitate other functions and a mechanical or powered actuation attachment unit which is to be installed onto the modified basic tape applicator unit to actuate other functions based on the requirement of the application.
