ABSTRACT:
The present invention relates to a package strapping machine suitable for tying a package or bundle into a circular shape. A concave base supports the package in the circular shape. A synthetic resin tape is looped around the package and the base, and a leading end of the tape is held against a lower surface of the base by a clamping mechanism. The tape is then tightened, and the leading end of the tape is clamped together with a trailing end of the tape. These tape portions are then heated and pressed to weld them together, and thus the packae is tied in a circular shape. The concave base is then pivoted out from between the package and the tape. As the base pivots, stoppers adjacent the base contact portions of the tape to hold the tape and package in place and allow the base to be removed.
