Abstract
A two-piece strapping tool having a manual tensioner and a battery-operated sealer is disclosed. The tensioner is a feedwheel tensioner that uses a serrated feedwheel to grip a first portion of the strap and a tension gripper to hold a second portion of the strap in a stationary position. The tensioner is configured to matingly receive the sealer between the tensioner's support legs such that the sealer may readily engage the overlapping portions of the strap to be welded. The sealer is battery-operated and uses a vibrational-type weld assembly driven by an electrical motor to weld overlapping portions of the strap. The sealer also includes a cutting assembly to sever the welded strap from a strap source.
