Abstract
Apparatus for tensioning a plastic strapping band positioned around a package and for connecting the overlapping ends of the band by hot bonding consisting of a fastening mechanism for hot bonding the overlapping ends of the band and including a backing plate, between the band and the package, against which three plungers aligned along the longitudinal axis of the band can be applied, the first plunger securing the free front end of the band, the second plunger securing the rear end of the band, and the third, middle, plunger forcing the overlapping ends of the band against a hot-bonding mechanism in the form of a heated cutter and compressing the molten ends together. The three plungers (27, 28, 29) aligned along the longitudinal axis of the band (20) are activated with a single cammed disk (31) on a shaft (67) perpendicular to the longitudinal axis of the band.
