ABSTRACT:
An improved strap tensioning tool, which is particularly adopted for use with non-metallic strap, in which the free end portion of a strap laced about an article which is to be strapped is gripped between an anvil and a wedge-shaped clamp member while the feed portion of such strap is engaged with a tension-applying means. The clamp member is floating supported for effectively gripping the strap during the initial tensioning thereof, regardless of the strap thickness, and a single operating lever serves to actuate the tensioning-applying means, facilitate tensioning of the strap free end portion after such portion is connected to the tensioned feed portion thereof, effect severance of the applied strap from a supply, and release of the clamp member.
