In a straps machine comprising strap-advancing rollers, a sensor for sensing whether a leading end of an advancing strap has reached a predetermined location within a predetermined time, and strap-retracting rollers, a severing and ejecting mechanism comprises a die and an anvil for severing the strap into a leading portion including the leading end and a trailing portion if the sensor has not sensed that the leading end has reached the predetermined location within the predetermined time. The mechanism also comprises a drivable roller, a motor for driving it, and two idle rollers on a pivotable yoke. The drivable roller and one of the idle rollers are operative for ejecting the leading portion after the strap has been severed. The drivable roller and the other idle roller are operative for feeding the trailing portion through the mechanism after the leading portion has been ejected.
For use with a strapping machine of a type having a strapping head, which includes means for advancing a strap fed into the strapping head, means for sensing whether a leading end of the strap being advanced by the advancing means has reached a predetermined location within a predetermined time, and means for retracting the strap, a mechanism comprising means coacting with the sensing means for severing the strap being fed into the strapping head into a leading portion including the leading end and a trailing portion if the sensing means has not sensed that the leading end has reached the predetermined location within the predetermined time and means coacting with the retracting means for ejecting the leading portion after the strap has been severed.
