ABSTRACT:
A number of elongate articles such as slide fasteners are discharged from a discharging mechanism and placed on a length of a band web which has been supplied from a reel on a bundle tray by means of a feed mechanism. The length of the band web has a free end and an opposite end gripped by a gripper mechanism. End portions of the length of the band web are ultrasonically fused to each other by a fusing mechanism constituted by an ultrasonic horn and an anvil. The opposite end of the length as it is gripped by the gripper mechanism is cut off by a cutter mechanism to form a band bundling the elongate articles, which are then discharged by the bundle tray.
