Patent ID: 8028623

Claim:
A contact-pressure adjusting method for a liquid application machine including: a first rotor to which liquid is supplied; a second rotor to which the liquid is supplied from the first rotor; a third rotor to which the liquid is supplied from the second rotor; first contact-pressure adjusting means for adjusting a first contact pressure between the first rotor and the second rotor; and second contact pressure adjusting means for adjusting a second contact pressure between the second rotor and the third rotor, the contact-pressure adjusting method comprising: measuring, by using temperature measuring means, at least one of: a temperature of at least one of a surface of the first rotor, a surface of the second rotor, and a surface of the third rotor, a temperature of at least one of liquid on the surface of the first rotor, the liquid on the surface of the second rotor, and the liquid on the surface of the third rotor, and a temperature of at least one of a vicinity of the first rotor, a vicinity of the second rotor, and a vicinity of the third rotor; and adjusting the first contact-pressure by the first contact-pressure adjusting means in accordance with the measured temperature by using a first conversion table indicative of a relationship between temperature and contact pressure between the first rotor and the second rotor, as well as adjusting the second contact-pressure by the second contact-pressure adjusting means in accordance with the measured temperature by using a second conversion table indicative of a relationship between temperature and contact pressure between the second rotor and the third rotor.
