AUTOMATIC TENSION SENSING APPARATUS FOR BELT CONVEYOR

摘要

A sensitive measurement of tension in a belt is provided by movement of a belt carrying pulley mounted on a pivoted arm extending from the pivot to a position beyond the pulley where a calibrated spring permits limited movement of the arm in opposition to belt forces on the pulley. The movement of the arm actuates limit switches which are operatively connected to a take-up pulley mechanism for maintaining the desired tension in the belt.
