Abstract
A self-actuating tension head for a strapping machine for feeding a steel strapping material around a load, tensioning the strapping material and sealing the strapping material to itself has a tension wheel biasing element. The tension head includes a body defining a strap path therethrough, a drive wheel, a tension wheel and a pinch wheel. The strap path extends between the tension wheel and the pinch wheel. The drive wheel is a fixed distance from the tension wheel. The drive and tension wheels are operably engaged with one another. A pivoting link operably connects the drive and tension wheels. The link pivots about the drive wheel axis of rotation. A cam is operably mounted to the tension wheel, and engages a cam follower to pivot the link to move the tension wheel into and out of engagement with the pinch wheel. The tension wheel biasing element cooperates with the cam to maintain the cam in a position relative to the cam follower.
