Abstract
A strapping machine is disclosed which is adapted to be capable of constantly attaining a stable secondary tightening force and thereby capable of preventing a band from coming off the object under strapping, which enables a reduced power consumption cost to be realized, and which can be constructed simply and inexpensively as a whole. The strapping machine comprises a feed/backfeed stepping motor M2 as a source of driving force for a mechanism F including a feed/backfeed roller 8 for conducting feed and backfeed of a band B to be looped around a periphery of an object to be strapped and the like operation; the strapping machine being provided with a reverse rotation preventive means 87, S for timely locking rotation of the feed/backfeed roller 8 in the feed direction D.sub.F of the band B while always permitting rotation of the feed/backfeed roller 8 in the backfeed direction D.sub.B of the band B.
