Abstract
A machine for making sealed liquid pouches with a free-floating straw inside the pouch is described. The machine comprises a vertical pouch former which forms a continuous plastic film tube from a film sheet with the plastic film tube disposed about a liquid dispensing spout. A straw convecting tube also extends to one side of the liquid dispensing spout inside the tube. A straw is released through the convecting tube at predetermined intervals in synchronism with a transverse sealer which forms a bottom and top edge seal of pouches as liquid is continuously dispensed through the liquid dispensing tube. The plastic film tube is maintained in a transversely expanded condition during the filling of the pouch and is advanced by an engagement mechanism between the sealing cycles.
