MODULAR FEED HEAD FOR A STRAPPING MACHINE WITH REVERSING MOTOR

摘要

A feed head ( 10 ) for a strapping machine ( 12 ) includes a frame ( 14 ), a feed wheel ( 20 ), a tension wheel ( 22 ), and a feed and take-up motor ( 18 ) mounted to the frame and operably connected to the feed wheel. The feed and take-up motor operates in forward and reverse directions to feed strapping material through the strapping machine, and to take up strapping material from the strapping machine. A tension motor ( 16 ) is operably connected to the tension wheel and operates in a reverse direction to tension the strapping material around the load. The tension wheel is movable toward and away from the feed wheel and engages the feed wheel during strap tension and disengages from the feed wheel during strap feed. A pivot assembly operably mounts the tension motor and tension wheel to the frame to move the tension wheel toward and into engagement with, and out of engagement with the feed wheel.
