An Improved Mode of Pressing Paper whilst in the Process of
Manufacture, Securing an Equal Surface on Both Sides of the
Paper, and Obtaining the Conditions Produced by Hand Pressing.
1, JAMES BALDWIN of Broad Meadow and Sherborne Paper Mills, King's Norton,
Worcestershire, Paper Manufacturer do hereby declare the nature of this invention
to be as follows:-
This improvement is accomplished by employing two felts at the first Press Rolls of the
Paper-making Machine, one felt passing round the bottom Press-roll in the ordinary
way the other felt passing round the top press-roll in a similar manner. Between
these two felts and the two rolls the paper is pressed and receives the impress of the
rough surface of the Felt on both sides. This mode of pressing makes the paper less
pervious, gives it greater tenacity than pressing with one felt only in the ordinary
way, and generally secures the conditions of hand-pressed paper in appearance and
strength.
The web of Paper after being pressed in the manner described may be dried on
steam-heated cylinders, on revolving frames, or led through heated rooms.

JAMES BALDWIN Broad Meadow King's Norton Worcestershire Manufacturer,
lo hereby declare the nature of this invention and in what manner the same
is to be performed to be particularly described and ascertained in and by the
following statement :-
:-
The improvement is accomplished by employing two Felts at the first Press-Rolls
of the Paper-making Machine. One felt passing round the bottom press-roll in the
ordinary way, the other passing round the top press-roll in a similar manner. Between
these two felis and the two rolls the paper is pressed and receives the impress of the
rough surface of the felts on each side. This mode of pressing makes the paper less
pervious, gives it greater tenacity than pressing with one felt only in the ordinary
way, and generally secures the conditions of hand pressed paper in appearance and
strength.
The web of paper after being pressed in the manner described, may be dried in the
ordinary way on steam-heated cylinders, on revolving frames, or may be led through
heated rooms.
The following description explains the accompanying drawings.
Fig. 1. represents the side elevation of the part of the paper-making machine to
which the process is adapted.
a, a, is a pair of press rolls used for pressing the paper whilst in a wet state. b. b. is
an endless felt passing between the rolls and round the bottom roll in the ordinary
way. c, c, is a felt of a similar description which also passes between the rolls and
round the top roll. d, d, is a framing supporting the rollers E, E, which carry the felt.
ff, are racks for moving the rollers to tighten the felt. g, g, is the web of paper
which enters between the rolls at the point h, and is pressed between the two rolls
and the two felts. It is then carried to the drying apparatus in any convenient
manner. i, i, are the drying cylinders or frames.
Fig. 2 is another sketch of-the side elevation-of--the-plan of pressing suited to a
paper-making machine of a different construction.
The same description will apply to this figure as to Fig. 1.

page_text: I wish it to be understood that I do not bind myself to the precise details herein
described and illustrated, as the system may be varied without departing from the
principle of my invention.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what
I claim is:
The arrangement by which two felts are worked in conjunction on the press-rolls of
the paper-making machine, and the web of paper in the process of manufacture, is
pressed between these two felts and not brought in contact with the metal rolls.
