Abstract: An electronic system for controlling the operation of a hand-held pull strap closure unit. The system includes a central processing unit which controls peripheral circuitry for directing commands to a motor within the hand-held unit. The system further includes a circuit for monitoring motor torque and a hand-held unit identification circuit for identifying each unit with an individualized code. The CPU may be accessed via an external communications port to store user-selected operational parameters in a memory circuit. These parameters may include time of day, calendar, and motor torque limits for each device.

Abstract: A method for drawing a bundling strap taut about the neck of a flexible container such as a bank bag, said bundling strap comprised of an elongated body portion having a plurality of serrations disposed along side edges thereof adapted to mate in locking contact with corresponding teeth members projecting into an aperture in a head-end portion connected to said strap body, the method utilizing an automatic bundling strap tensioning apparatus characterized by a reversible motor means connected to a reciprocating means for gripping moveable between an extended position and a retracted position, comprised of the steps of:looping said bundling strap about the open neck of said flexible container;inserting the tail end of the strap through the aperture defined by the head-end portion of the strap;pulling said tail-end of said strap completely through said aperture until at least the first set of serrations of the strap body are engaged by said teeth members projecting upwardly into the interior of the aperture, th

Abstract: A one-piece tamper-proof bundling strap comprised of a head-end portion defining an aperture therethrough, the head-end portion being integrally connected to an elongated narrow body portion, the aperture in the head-end portion corresponding generally to the cross-sectional configuration of the body portion. The head-end portion and the body portion have a locking means integrally associated therewith for preventing reverse movement of the body portion relative to the head-end portion when the body portion is looped upon itself and disposed within the aperture of the head-end portion. The locking means is comprised of a plurality of serrations oriented along a portion of the length of the body portion and a plurality of projecting teeth members disposed within said through-aperture adapted to lock against the serrations when the body portion is looped upon itself and drawn through the aperture in the head-end portion.

Abstract: A hand-held apparatus for tensioning a bundling strap about an item to be bundled having a motor and a rotatable output shaft coupleable to one end of an elongated external screw threaded shaft supported for rotation at its opposite end by an end cap. A guide block is adapted for linear reciprocal movement along the shaft between the hand-held unit and the end cap and has threads corresponding to screw threads on the shaft, the guide block having connected thereto means for gripping the bundling strap. A reversible power means energizes the hand-held unit and reverses or halts the direction of rotation of the output shaft upon exertion of a predetermined force upon the guide block.

Abstract: A bundling strap of the type having an apertured head portion with an embedded resilient tongue, to receive and secure a strap therein, an end of the strap being attached to the head portion, and a security cap comprising a four-sided housing surrounding the head portion, and having body segments which when moved relative to each other will fracture apart so as to expose tampering.
