Abstract
A strapping machine automatically adjusting the strap tension includes a sensor to interact with two sense members fixed on a subordinate wheel of an advance and retreat device, which consists of a main wheel and the subordinate wheel. The sensor and the sense members sense the advanced and the retreated rounds of the subordinate wheel when a strap is moved through a gap between the main wheel and the subordinate wheel. Then sensor sends a signal of the length practically needed to bind the strap around an object to a signal processor, which calculates and records and sends the difference cardinality to a controller. Then the controller controls operation and stopping of the motor of a strap tension device according to the signal so that the strap machine can automatically adjust the strap tension for binding the strap.
