Abstract
A pouch machine vertical sealer capable of fusing a pouch film web to form a plurality of spaced vertical seals along a length of the film web to form pouches. The pouch machine vertical sealer includes a sealer wheel rotatable about a vertical axis of rotation and defines a film web path about a periphery of the sealer wheel. The vertical sealer further includes a plurality of vertical sealer land assemblies spaced apart about the periphery of the sealer wheel. Each vertical sealer land assembly includes an impulse heater such that contact between the film web and each impulse heater of the plurality of vertical sealer land assemblies forms the spaced apart vertical seals along the length of the film web.
Claims22
A pouch machine vertical sealer capable of fusing a pouch film web to form a plurality of spaced vertical seals along a length of the film web, comprising:
- a sealer wheel rotatable about a vertical axis of rotation and defining a film web path about a periphery of the sealer wheel;
- and
- a plurality of vertical sealer land assemblies spaced apart about the periphery of the sealer wheel and each comprising an impulse heater;
- wherein contact between the film web and the impulse heater of each of the plurality of vertical sealer land assemblies forms the spaced apart vertical seals along a length of the film web.
A method of fusing pouch film web to form a plurality of vertical seals along a length of the film web to form pouches, comprising:
- providing a pouch machine vertical sealer having a sealer wheel rotatable about a vertical axis of rotation and defining a film web path about a periphery of the sealer wheel, and a plurality of vertical sealer land assemblies spaced apart about the periphery of the sealer wheel and each comprising an impulse heater;
- rotating the vertical sealer to entrain the film web around the sealer wheel;
- engaging the film web with the impulse heater of the plurality of vertical sealer land assemblies and sealing the film web to form a vertical seal at the impulse heater of the plurality of vertical sealer land assemblies;
- and
- reciprocating one of the plurality of vertical sealer land assemblies or the plurality of rollers radially outwardly and inwardly with respect to the other one of the plurality of vertical sealer land assemblies or the plurality of rollers to selectively create a space between the film web and the impulse heater of the plurality of vertical sealer land assemblies.
A vertical sealer land assembly for use in a pouch machine vertical sealer and capable of fusing a pouch film web, comprising:
- an impulse heater located on the vertical sealer land assembly for generating heat to thermally seal the film web in contact with the impulse heater to form a vertical seal;
- and
- a cooling medium passageway that extends through the vertical sealer land assembly for cooling of the impulse heater.
