Abstract
A heat sealing machine and method form blister packages. A backing material web extends between a nesting tray assembly and a seal and cut tooling assembly and a blister tray is resident within a blister nest of the nesting tray assembly. The backing material web is clamped between a clamping gasket support shoulder of the nesting tray assembly and a clamping shoulder of the seal and cut tooling assembly, and between a sealing gasket support shoulder of the nesting tray assembly and a heat seal shoulder of a heater assembly. A knife of the seal and cut tooling assembly extends between the clamping gasket support shoulder and the sealing gasket support shoulder to cut a backing sheet from the backing material web that is heat sealed to an attachment surface of the blister tray to form the blister package.
Claims7
A method for heat sealing a blister package comprising:
- extending a backing material web between a nesting tray assembly and a seal and cut tooling assembly of a heat sealing machine, wherein a blister tray of the blister package is resident within a blister nest of the nesting tray assembly, wherein the seal and cut tooling assembly is mounted below a heater assembly of the heat sealing machine with a heat seal block of the heater assembly extending downward through a heat seal block opening of the seal and cut tooling assembly;
- clamping the backing material web between a clamping gasket support shoulder of the nesting tray assembly and a clamping shoulder of the seal and cut tooling assembly;
- clamping the backing material web between a sealing gasket support shoulder of the nesting tray assembly and a heat seal shoulder of the heat seal block, wherein the clamping gasket support shoulder and the sealing gasket support shoulder define a knife slicing groove therebetween;
- and
- extending a knife of the seal and cut tooling assembly between the clamping gasket support shoulder and the sealing gasket support shoulder and into the knife slicing groove to cut a backing sheet of the blister package from the backing material web.
