Sealing head for modular steel strapping machine

A sealing head for a strapping machine welds steel strapping material to itself in an end-to-end weld. The sealing head includes a body, a drive, an end grip at the inlet to the body, a cutter, a grip clamp and a loop grip downstream of the end grip. The loop grip is carried on a carriage that is mo...

Zusammenfassung:	A sealing head for a strapping machine welds steel strapping material to itself in an end-to-end weld. The sealing head includes a body, a drive, an end grip at the inlet to the body, a cutter, a grip clamp and a loop grip downstream of the end grip. The loop grip is carried on a carriage that is movable in a direction along the strap path. A leading end of strap is secured by the end grip and a loop portion of the strap is gripped by the loop grip and severed by the cutter to form a loop end. The loop end is secured by the grip clamp. The loop grip carriage moves the loop end toward the leading end as current is passed though the loop end and the leading end to weld the ends to one another in an end-to-end weld.
