Abstract
A continuously driven endless belt trains about deflection rolls within a frame which surrounds a tunnel for the reception of the package which is to be strapped or tied with a ligature in the form of a plastic strap or band. Connectable with the revolting belt is a carriage which guides the plastic strap or band withdrawn from a supply roll along a prescribed path of travel about the tunnel. After each revolving motion of the plastic strapping band the carriage is again uncoupled from the endless belt at the region of a strap wrapping and connection unit, in order to transfer the starting portion of the strapping band which has been guided around the package to a strap or band closure device and, following the tensioning and cutting of such band, to engage a new starting band portion to accomplish the next strapping of the band about a new package. With such construction of the package strapping machine it is only necessary to again accelerate and brake the carriage which possesses low mass during each operating cycle of the machine, so that there is no need for any control device for the belt drive and there is possible an extremely high acceleration of the carriage for carrying …
