Abstract: A method and apparatus in which a strap looped about an article is tensioned by applying positive pulling forces to both the leading end and feed portions of such strap loop, after which such strap positions are sealed together. In certain embodiments of the invention, a strapping mechanism is supported on a carriage which is movable toward the article which is to be strapped, after which a strap looped about such article is tensioned by applying pulling forces to the leading end and feed portions thereof.
Abstract: An improved method and apparatus, and a new metal seal for use in securing overlying portions of generally flat, non-metallic strap with little or no strap bulging under applied seal-closing forces and with a firm interlock between the applied seal and embraced strap portions.
