Abstract

A modular strapping machine feeds steel strapping material around a load, tensions the strapping material and welds the strapping material to itself in an end-to-end weld. The modular strapping machine includes a frame, a feed head removably mounted to the frame, a tension head removably mounted to the frame, a sealing head removably mounted to the frame and a strap chute. A strap straightener is mounted between the tension head and the sealing head. A leading end of the steel strapping material is conveyed from the feed head, through the tension head and the sealing head, through the strap chute and back to the sealing head. The sealing head is configured to grip the leading end, grip and sever a trailing end of the strapping material to form a loop end and weld the leading end to the loop end in an end-to-end weld.
