ABSTRACT:
A heat sealing and cutting mechanism to form a heat seal and a cut across a tube of flexible packaging material includes a carrier to contact the tube. A pair of closely spaced heat sealing bands are disposed on the carrier and are energizable to form closely spaced heat seals across the tube when the carrier is in contact with the tube. The heat sealing bands are configured to define temperature gradients along the heat sealing bands. A cutting wire is also disposed on the carrier and is positioned between the heat sealing bands. The cutting wire is energizable to cut the tube when the carrier is in contact with the tube.
