IMPROVEMENTS IN APPARATUS FOR COOLING AND MOISTENING PAPER
Year: 1882

page_text: LETTERS PATENT to Friedrich Carl Glaser, of Berlin, in the Kingdom of
Prussia, and Empire of Germany, Engineer and Patent Solicitor, for an
Invention of" IMPROVEMENTS IN APPARATUS FOR COOLING AND MOISTENING
PAPER." A communication by Heinrich Felix Schöller, residing at Düren, in
the German Empire.
PROVISIONAL SPECIFICATION left by the said Friedrich Carl Glaser at
the Office of the Commissioners of Patents on the 26th January 1882.
FRIEDRICH CARL GLASER of Berlin in the Kingdom of Prussia and Empire of
Germany, Engineer and Patent Solicitor. "IMPROVEMENTS IN APPARATUS FOR
COOLING AND MOISTENING PAPER." [A communication by Heinrich Felix Schöller,
a person residing at Düren, in the German Empire.]
This invention relates to apparatus whereby the paper issuing from the paper
making machine in a heated and perfectly dry condition, may either be only cooled
in order to discharge any accumulation of electricity therefrom, and to render it
less stiff, or be both cooled and moistened, for improving the sizing and to enable
the paper to undergo the subsequent calendering process better.
The said apparatus is shewn on the accompanying drawing, in which Fig 1 shews
a side elevation, Fig 2 a front view and Fig 3 a plan. It consists of a revolving
hollow cooling cylinder A of cast iron coated with copper, through the axis of
which pipes are led for the introduction of cold water, which is made to circulate
continuously through the same to prevent its becoming heated.
The heated paper
coming from the machine as indicated by dotted lines passes round the circum-
ference of this cylinder against which it is pressed by an endless travelling
blanket E and whereby it is caused to give off its heat to the cooled cylinder
surface. Below the cylinder A is a watertrough B which when it is desired to
moisten the paper at the same time that it is cooled, is filled with water so that the
blanket E in passing over the lower rollers partly immersed in the water as shewn,
becomes more or less saturated with the water, and consequently imparts the
required moisture to the paper. An adjustable pressing roller C presses the
blanket E to the required extent against the paper whereby the amount of
moisture taken up by the latter can be regulated and the uniform moistening
thereof be insured.
On emerging from the water trough the blanket is caused to pass between two
adjustable pressing rollers D whereby the amount of water taken up by the
blanket may also be regulated.

FRIEDRICH CARL GLASER of Berlin in the Kingdom of Prussia and Empire of
Germany, Engineer and Patent Solicitor. "IMPROVEMENTS IN APPARATUS FOR E
COOLING AND MOISTENING PAPER." A communication by Heinrich Felix Schöller,
residing at Düren in the German Empire.
This invention relates to apparatus whereby the paper issuing from the paper
making machine in a heated and perfectly dry condition, may either be only cooled
in order to discharge any accumulation of electricity therefrom and to render it 1
less stiff, or be both cooled and moistened, for improving the sizing and to onable
the paper to undergo the subsequent calendering process better.
The said apparatus is shewn on the accompanying drawing, in which Fig. 1 shews
a side elevation, Fig. 2 a front view and Fig. 3 a plan. It consists of a revolving
hollow cooling cylinder A of cast iron conted with copper, through the axis of 1
which pipes are led for the introduction of cold water, which is made to circulate,
continuously through the same to prevent its becoming heated. The heated paper
coming from the machine as indicated by dotted lines passes round the circum-
ference of this cylinder against which it is pressed by an endless travelling

surface. Below the cylinder A is a water trough B which when it is desired to
moisten the paper at the same time that it is cooled, is filled with water so that the
blanket E in passing over the lower rollers partly immersed in the water as shewn,
becomes more or less saturated with the water, and consequently imparts the required
moisture to the paper. An adjustable pressing roller C presses the blanket E
to the required extent against the paper, whereby the amount of moisture
taken up by the latter can be regulated and the uniform moistening thereof be
insured.
On emerging from the water trough the blanket is caused to pass between two
adjustable pressing rollers D whereby the amount of water taken up by the blanket
may also be regulated.
Having thus described the nature of this invention and in what manner the
same is to be performed as communicated to me by my correspondent I claim :-
The construction and use of apparatus for cooling and moistening paper
consisting of a cylinder A cooled internally by water and an endless blanket E
surrounding the cylinder such blanket being supplied with water from the bath B
and subjected to regulated pressure by the rollers C and D for removing excess of
moisture therefrom,
In witness whereof I the said Friedrich Carl Glaser have hereunto set my
hand and seal this fifteenth day of July, in the year of our Lord One
thousand eight hundred and eighty two.
