Abstract
A strapping machine for applying a band around an object includes a pool box in which slackened band is accumulated prior to be fed around an object by a main feed mechanism. The pool box contains a feed device which draws-in the band from a reel, and a passage-forming structure for guiding the band toward the main feed mechanism. The passage-forming structure contains a balance bar and an opposing guide arm. The balance bar is displaced by the band as the band accumulates in the passage. When the balance bar is displaced by a predetermined amount, a sensor shuts off the feed device. Thereafter, the guide arm is moved to a passage-enlarging position, whereupon the balance bar is permitted to return to its original position, enabling the feed device to resume its feeding of the band. The band thus accumulates within the enlarged passage.
