Abstract
This invention provides a method of removing an idle strapping band in which a band restored and retracted by a reverse rotation roller is wound around the end of a slide table forms a ring of the band in case of no article to be strapped and engaged with the band on a strapping machine body, a rotation reduction detection signal of the reverse rotation roller is not generated before the setting time of a timer is completely elapsed before the band is tightened, a band tightening step is then omitted, shifted to next cutting and fusing steps of the band supplying end, the ring of the band is then recoiled upward by means of elastic force for restoring the ring of the band to a true circle when the end of the slide table is retracted along guide rails and the band is automatically removed out of a band fusing mechanism. A band tightening is executed by a tension arm, a cam shaft is normally rotated to be stopped before the band is fused after the band supplying end is cut, the cam shaft is then reversely rotated to its original position, the holding of the end and supplying end of the band wound around the end of the slide table and tightened is relieved, and the band is recoiled above the slide table by means of the elastic force of the band itself and the tightened tension force to be removed.
