A severing and sealing tool having a single head with electrically resistive wires passing there across. The wires are connected to an electric source which provides power selectively to the wires for severing and sealing a thermoplastic material such as a strap along an overlapping portion thereof. The electrically resistive wire is heated to a temperature sufficiently high to melt the thermoplastic material, but not high enough to decompose the material. The metallic body of the tool is formed in two parts with an insulating material disposed between the two parts with the electrically resistive wires having an end connected to each of the parts. One electrically resistive wire traverses completely across the predetermined area of the head which comes in contact with the thermoplastic material. The other electrically resistive wire meanders through a part of the predetermined area of the head which is in contact with the thermoplastic material. Electrical energy is supplied to each of the two parts of the body of the tool and the electrically resistive wires are insulated except at their ends from the metallic substance of the tool for providing the necessary electrical circuit to provide electrical power to the electrical resistive wires thereby heating the wires.

Severing and sealing tool

A strapping apparatus for applying a thermoplastic strap about an object by placing an end of the strap away from a supply thereof against the object and wrapping the portion of the strap adjacent that end about the object by rotating the object. Tensioning means is provided to pull the strap tightly about the object as the object is rotated by a platen. A clamp is located adjacent the platen to hold the object engaged with the platen as the platen is rotated in a first rotary direction. A cutting and sealing tool moves against a portion of the strap which is overlapped forming two layers of strap. The tool applies heat to the thermal plastic strap to soften the strap cutting away the portion of the strap toward the supply and sealing a segment of the overlapping portion together. The platen is then derotated in a second rotary direction opposite to the first rotary direction and the clamp means loosened so that the object which is wrapped with the strap falls from the platen. The platen is movable horizontally between two positions.
