Abstract
An inkjet printer prints variable image identifying information on a substrate with a first side having a release agent thereon and a second side having an activated chemical adhesive thereon. The inkjet printer includes at least one inkjet head for transferring an ink to the first side of the substrate and a pair of opposed guide rollers, a nip roller assembly and a driven platen roller opposite the inkjet head for advancing the substrate past the inkjet head. The inkjet printer further includes a fuser for drying the ink immediately after the variable identifying information is printed on the substrate. Preferably, the variable identifying information is printed on the substrate at a rate that is compatible with the operating speed of a tape applicator on a conventional high-speed production line.
Claims16
An apparatus for printing variable identifying information on a substrate, the substrate comprising a first side having a release agent thereon and a second side having an activated chemical adhesive thereon without a liner, said apparatus comprising
- at least one inkjet head for transferring an ink onto the first side of the substrate;
- means for advancing the substrate past said at least one inkjet head;
- and
- a fuser for drying the ink transferred onto the first side of the substrate, said fuser comprising
- a pneumatic chamber;
- a blower unit for generating a stream of ambient air, said blower unit in fluid communication with said pneumatic chamber;
- a nozzle having an entrance port for receiving the stream of ambient air and an exit port for directing the stream of ambient air onto the first side of the substrate;
- a heating coil positioned within said pneumatic chamber for heating the ambient air in said pneumatic chamber;
- and
- a thermocouple positioned within said pneumatic chamber for monitoring the temperature of the heated air in said pneumatic chamber.
An apparatus for printing variable identifying information on a substrate, the substrate comprising a first side having a release agent thereon and a second side having an activated chemical adhesive thereon without a liner, said apparatus comprising
- at least one inkjet head for transferring an ink onto the first side of the substrate;
- means for advancing the substrate past said at least one inkjet head;
- and
- a fuser for drying the ink transferred onto the first side of the substrate, said fuser comprising
- a pneumatic chamber;
- a blower unit for generating a stream of ambient air, said blower unit in fluid communication with said pneumatic chamber;
- an ultraviolet light bulb positioned within said pneumatic chamber;
- and
- a nozzle having an entrance port for receiving the stream of ambient air and an exit port for directing the stream of ambient air onto the first side of the substrate.
An apparatus for printing variable identifying information on a substrate, the substrate comprising a first side having a release agent thereon and a second side having an activated chemical adhesive thereon without a liner, said apparatus comprising
- at least one inkjet head for transferring an ink onto the first side of the substrate;
- means for advancing the substrate past said at least one inkjet head;
- and
- a fuser for drying the ink transferred onto the first side of the substrate, said fuser comprising
- a pneumatic chamber;
- a blower unit for generating a stream of ambient air, said blower unit in fluid communication with said pneumatic chamber;
- a nozzle having an entrance port for receiving the stream of ambient air and an exit port for directing the stream of ambient air onto the first side of the substrate;
- and
- a butterfly valve positioned between said pneumatic chamber and said entrance port of said nozzle, said butterfly valve comprising a plate that is movable relative to said entrance port of said nozzle to vary the amount of ambient air that is permitted to enter and subsequently exit said nozzle.
An apparatus for printing variable identifying information on a substrate, the substrate comprising a first side having a release agent thereon and a second side having an activated chemical adhesive thereon without a liner, said apparatus comprising
- at least one inkjet head for transferring an ink onto the first side of the substrate;
- means for advancing the substrate past said at least one inkjet head;
- and
- a fuser for drying the ink transferred onto the first side of the substrate, said fuser comprising
- a pneumatic chamber;
- a blower unit for generating a stream of ambient air, said blower unit in fluid communication with said pneumatic chamber;
- a nozzle having an entrance port for receiving the stream of ambient air and an exit port for directing the stream of ambient air onto the first side of the substrate;
- a melt tank for receiving the ink in a solid form;
- a beating coil positioned within said melt tank for melting the ink;
- and
- means in fluid communication with said melt tank for delivering the melted ink to said at least one inkjet head.
