ABSTRACT:
A strapping machine includes a pair of motor-driven feed rollers for feeding a band from a pool box and into encompassing relation to an object to be strapped. A pre-feeding roller pair is disposed between the pool box and the feed rollers for pre-feeding the band to the feed rollers. The pre-feeding roller pair is normally in a rest position which permits the band to travel therepast. When manually rotated, the prefeeding roller pair positively advances the band to deliver a leading end thereof to the feed rollers. A sensor detects rotation of the pre-feeding roller pair to energize the feed rollers for a predetermined time period to advance the band.
