摘要

The packaging machine has two transverse heat-sealing jaws for sealing a packaging. The former transverse heat-sealing jaw is supported against the other transverse heat-sealing jaw with an adjustable and predetermined force generated by a force generating unit. Another force generating unit is provided for generating a pressure required for sealing. The force generated by the former force generating unit is smaller than the force generated by the latter force generating unit.
