Abstract
A device (10) for heating ink on a printed web (12) from a printing press (14) having a tunnel (16) defining a chamber (18) which has an inlet (20) for introducing the web (12) into the chamber (18), and an outlet (22) for removing the web (12) from the chamber (18). The device (10) has a microwave power source (24) for introducing microwave energy in the chamber (18) in order to heat the web (12) and heat set inks on tile web (12).
Claims15
A device for heating a printed web associated with a printing press, comprising:
- means defining a chamber having an inlet for introducing the web into the chamber, and an outlet for removing the web from the chamber;
- and
- means for introducing a source of microwaves into the chamber to heat the web and heat set an ink on the web, including a layer of microwave energy absorbing means covering opposed sides of the web.
A device for heating associated with a printing press, comprising:
- a web having a printed ink on at least one surface of the web;
- means defining a chamber;
- means for passing the web through the chamber;
- a source of microwave energy;
- means for passing the source into the chamber to heat the ink on the web;
- means for passing air through the chamber to remove solvent from the chamber;
- means for absorbing a portion of the microwave energy adjacent opposed surface of the web;
- and
- means for defining a reflective surface to the microwave energy in the chamber, with the reflective surface being located approximately 1/4wavelength of the microwaves from the web or any odd multiple of quarter wavelengths of the microwaves from the web.
