A power strapping tool having an anvil and a tensioning wheel adapted to engage with overlapping portions of a strapping looped about a package and extending to a supply. The tensioning wheel is rotatable in a direction as to tension the loop of strapping and maintain such strapping tensioned while overlying portions thereof are connected to each other and then in an opposite direction to relax and flex away from the underlying strapping portion a span of the overlying strapping extending between such wheel and the location of strapping connection to thereby position such flexed, overlying strapping portion for easy severence. In the preferred embodiment, rotation of the tensioning wheel is also relied upon to effect projection of a knife between the overlying flexed and the underlying strapping portions and to then again tension the overlying strapping portion whereby the flexed strapping is urged against the projected knife to thereby sever the applied loop of strapped from its supply.
A tool for tensioning a length of strapping about a package and preparing the same for severence from a strapping supply, said tool having a main body, an assembly including an anvil mounted on said main body, a wheel, means supporting said wheel for rotation relative to said main body, said anvil and said wheel being adapted to engage, respectively, with an end portion and an overlapping intermediate portion of strapping looped about a package and extending to a supply, and means on said main body for rotating said wheel in one direction for tensioning the loop of strapping and maintaining the same tensioned during connection of overlapping portions thereof to each other at a location removed from said wheel, and in an opposite direction for flexing away from the underlying strapping portion a span of the overlying strapping portion extending between said wheel and the location of strapping connection.
