humidifies the atmosphere in the housing 32, this humidity can also be transferred into
chamber 22.
Van Haag teaches (column 6, lines 33-55) that the apparatus 1 works in the
following manner:
A roll 2 of sheet material is deposited, for example, with the help of a
crane or a lifting vehicle, on the first storage space 16 of the roll magazine 15.
Whenever a roll 2 has been unwound in the unwinding station 11, this taking a
time ranging from 1 to 2 hours, a roll 2 in the roll magazine 15 moves one
storage space further to the right and finally reaches chamber 22. The roll is
acted upon here by means of an elevated temperature and/or elevated humidity,
so that the temperature distribution, which may have become nonuniform during
storage in the roll magazine 15, becomes uniform once again. Thus, during the
unwinding in the unwinding station 11, a roll of material conditioned to a relatively
uniform temperature over its length and width, is unwound and supplied to the
treatment station. In the treatment station 5, the sheet material 3 is exposed not
only to high pressure and an elevated temperature in the roller gap of the stack
of rollers 6, 7, 13 but also to elevated humidity which has been produced by the
steam generator 40. The humidity is controlled by the measuring instrument 44,
for example, to a value corresponding to the ambient humidity in a printing shop,
in which the sheet of paper is to be processed.
Palmatier
Palmatier's invention relates to a printing unit for using water based inks in high
speed rotary printing presses. Figure 1 shows a printing unit 1 in accordance with one
embodiment of Palmatier's invention. The printing unit 1 includes side walls 2
supporting upper and lower inking units 55.1, 55.2, blanket cylinders 4, 6 and print
cylinders 3, 5. The printing unit 1 is designed to maintain acceptable printing conditions
