Abstract
A vertical form, fill and seal packaging machine having plows for forming an advancing web of thermoplastic material into a depending upwardly opening tubular configuration. A heat sealing belt located below the forming plows, seals overlapping marginal portions of the web together to form a long seam. A sealing jaw mechanism located below the plows in vertically stationary relation thereto includes a pair of coupled rotary actuators which move links in opposite directions to open and close sealing jaws which form transverse seals at spaced intervals along the formed tube to complete the packages.
