An expand-and-constrict type band-guiding device for a strapping machine includes an expand-and-constrict unit, an elastic coiled rod, a receiving member, a roller unit, a motor and a clamp device. The clamp device clamps the end of a strap band, and the motor drives the roller unit for moving the elastic coiled rod to push outward an elongate shift member. Then the strap band with its end pushed to extend by the shift member and then released by the clamp device in due time, with the end of the strap band pushed to the other side from under a storage board for an operator of the strapping machine to catch the strap band.
