Abstract: An ultrasonic tying tool for installation of a tape about a bundle of elongate articles. The tool includes an ultrasonic horn wherein the welding tip is moveable between a first position for welding of a tape to secure the tensioned loop about the plurality of articles and a second position wherein the welding tip is translated a distance from the first position to effect cutting of the tensioned loop from the stock of tape and to tack weld the loose cut end to the underlying tape of the loop to eliminate any protruding sharp edges. The tool additionally includes a belt drive mechanism for advancing the tape to the jaw assembly and for tensioning the tape following looping of the tape about the outside.

Abstract: An improved cable tie dispensing apparatus includes a cutting and feeding apparatus which advances and severs a cable tie from an elongate strip of cables ties for delivery to an automatic cable tie installation tool. The cutting and feeding apparatus provides an elongate platform for supporting a cable tie strip therealong and a severing location adjacent one end of the platform which is defined to support one cable tie. An alignment pilot is supported adjacent the severing location and is movable towards the severing location so as to separate the supported cable tie from the strip to which it is connected. The alignment pilot includes a punch for severing the web between adjacent cable ties upon movement of the pilot toward the severing location. A firing chamber is included which has an open face for insertion of a single cable tie therein. The open face is sealably closed by movement of the pilot toward the severing location.

Abstract: An improved orientation means for a cable tie delivering system is adapted to complement a cable tie delivery system and includes an elongated conduit for orientation of an elongated, generally planar cable tie therein. The elongated conduit orients either a symmetrical or a single-directional cable tie in a delivery hose extending between a cable tie application tool and a dispenser from which such a cable tie is ejected. The conduit achieves proper orientation of the cable tie by requiring the cable tie to bend as it travels from the dispenser to the tool. By confining the cable tie once it has achieved the desired orientation the conduit retains the cable tie therein for accurate delivery to the installation tool and proper application to a bundle of articles to be tied.

Abstract: A cable tie includes an elongate generally planar strap and a head. The head of the cable tie includes an aperture therethrough for insertably accommodating the strap. The head of the cable tie also includes a barb embedding surface adjacent the aperture through the head. A metallic locking barb is embedded in the embedding surface in a direction substantially parallel to the aperture in the head. The metallic locking barb is bent to form an obtuse angle so that the metallic locking barb extends into the aperture in the head to permit movement of the strap in an insertion direction and to prevent substantial movement of the strap in a withdrawal direction.

Abstract: A tool for crimping an elongate electrical contact to an end of an electrical wire. The tool includes a locating device supported adjacent the crimping dies of the crimping tool for supporting and locating the contact in proper position between the dies. Upon crimping, the contact is subject to deformable elongation in its longitudinal direction. The locating device is supported to the tool against the bias of the spring to be movable away from the tool to accommodate such contact elongation caused during crimping.
