A strap clamping and severing assembly which cooperates with a movable sealing head of a strapping tool and performs the multiple functions of first clamping the free end of a length of strapping in a fixed position preparatory to creating a loop of the strapping about an article; secondly, of guiding the feed end of the loop during the tensioning operation in overlapped relation to the clamped free end; thirdly, of severing the feed end of the loop from the strapping source after the tensioning operation; and fourthly, of retaining the severed end of the strapping source in an accessible position to facilitate the next succeeding strapping operation. When used with a vibratory sealing head which effects a fusion joint on the loop overlap, the assembly vibrates in unison with the head and severs the strap directly at the edge of the sealing area to eliminate a protruding tail.
