ABSTRACT:
The endless belt of a gravimetric feeder is provided with a tracking and tensioning assembly which is mounted for rotation about a vertical axis. The assembly is also mounted for movement along said axis between operative and inoperative positions. In the operative position of the assembly, it tensions the belt and instantly corrects any tendency of the belt to move sideways. The assembly also maintains the inner surface of the belt clean by scraping the same when the assembly is in its operative position.
