In another aspect, first and second frame sections are pivotally attached, the first section having cylinder means mounted thereon, the second section having cylinder means mounted thereon, the second section having a pair of dies housed therein for fastening the strap. Apparatus is provided for rotating the cylinder rod to vary the length engagement of a threaded member with a threaded portion extending axially from the cylinder rod to adjust the stroke of the upper die for various strap thicknesses.
