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 Connectable with the revolting beltis a carriage which guides the plastic strap or band withdrawn from a supply roll along aprescribed path of travel about the tunnel.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