Various embodiments of the present disclosure provide a strapping machine strap-feeding assembly that changes the speed of its drive roller from one strap-feeding cycle to the next or during a single strap-feeding cycle to reduce slippage between the drive roller and the strap.

Various embodiments of the present disclosure provide a strapping tool configured to tension metal strap around a load and, after tensioning, attach overlapping portions of the strap to one another by cutting notches into a seal element positioned around the overlapping portions of the strap and into the overlapping portions of the strap themselves.
