Abstract
A tool for sealing overlying courses of a strap that includes a gripping unit, a power supply unit detachably affixed to one end of the gripping unit, and a motor in the gripping unit. A cam is coupled to the motor and a notching unit is coupled to the cam by a plurality of linkages.
Claims16
A hand-held sealing tool for sealing a strap, comprising:
- a gripping unit having a housing with a bore extending therethrough, the housing configured to be engaged by a user's hand during operation of the sealing tool;
- a power supply unit detachably affixed to one end of the gripping unit;
- a motor positioned at least in part in the bore of the housing;
- a cam coupled to the motor;
- a notching unit attached to another end of the gripping unit and coupled to the cam by a plurality of linkages, the notching unit having a first jaw and a second jaw positioned on opposite sides of a strap feed path,
- wherein the first jaw and the second jaw are configured to rotate to create a notch in a strap.

A method of operating a sealing tool including the steps of:
- receiving an operation signal from a switch;
- receiving a strap position signal from a strap sensor indicating that a strap is positioned in a notch plate;
- providing power from a power supply unit to a motor in a gripping unit;
- driving a first jaw and a second jaw of a notching unit to rotate via a cam coupled to the motor and the power supply unit, in response to receipt of the operation signal and the strap position signal, to create a notch in the strap.
