APPENDIX
13. A system for marking a continuous substrate,
comprising:
a) an elongate housing, having an inlet end and an outlet
end, for housing the continuous substrate as the continuous
substrate is directed through the housing from the inlet end to
the outlet end;
b) an elongate heater disposed within the elongate housing
and extending from the inlet end to the outlet end of the
elongate housing;
c) an outlet tube disposed proximate to the elongate
heater and substantially parallel to the elongate heater within
the elongate housing, the outlet tube having a gas inlet at a
first end and defining a plurality of gas outlets disposed along
a substantial portion of the length of the outlet tube, whereby a
significant portion of gas directed through the gas inlet into
the outlet tube is heated by the elongate heater, while being
conducted through the outlet tube, and is then discharged from
the outlet tube through the gas outlets toward the continuous
substrate in the housing, thereby passing across the continuous
substrate and heating the aqueous-based ink in an amount
sufficient to cause a pigment of the aqueous-based ink to bond to
the continuous substrate and thereby mark the continuous
substrate.
