ABSTRACT:
A machine and method for forming, filling and sealing closed individual pinch pouches includes a support for holding a continuous supply of material having a solid bleached sulfate board or paper board surface and a heat sealable plastic coating on one side. A folding apparatus folds the web material onto itself with the heat sealable surface facing itself with a gusset at the fold. Drive rollers pull the material from the source through the folding apparatus. Heating bars form a seal between selected portions of the material by sealing the heat sealable surfaces at intermittent portions. A cutter cuts the material through the seal and forms a blank having opposed sealed edges extending to the gusset and an open edge opposite the gusset. A hammer pushes the gusset of the blank inward to spread apart opposed surfaces of the blank. An injector forces a flowable substance into the blank through the open edge. A sealer engages the open edge opposite the gusset to force a selected area of the edge together to form a sealed closed pinch pouch.
