IMPROVEMENTS IN CALENDERING MACHINES FOR GLAZING AND FINISHING PAPER AND SIMILAR MATERIAL
Year: 1884

page_text: I, OLIVER IMRAY of No 28 Southampton Buildings, Chancery Lane, in tho
county of Middlesex, Patent Agent, do hereby declare the nature of the said
invention for "IMPROVEMENTS IN CALENDERING MACHINES FOR GLAZING AND
FINISHING PAPER AND SIMILAR MATERIAL" to be as follows:-
The present improvements have for their object the better guiding of the paper
while passing between and along the rollers of the calendering machine, and consist
essentially of means for enabling the use of compressed air or steam for this
purpose.
The paper may be either in sheets or in a continuous web.
I arrange parallel to the rollers and close to the same a set of tubes having
perforations or slits opposite to the rollers. The said tubes are connected to any
suitable blower for forcing a current of air through them, or they are connected
with a steam pipe for admitting steam, or with any other suitable means for forcing
air or steam or other suitable gases through them.
The paper passing under the first (highest) roller, and having any tendency to
adhere to it, is blown off it by the blast proceeding from the uppermost perforated
tube, and is pressed against the second (lower) roller by the blasts proceeding from
other lower perforated tubes.
On the paper passing under the second roller, blasts proceeding from further
perforated tubes also first detach the paper from the second roller and then press it
against the third roller, and this action is continued until the paper has passed
through the entire set of rollers.

page_text: I, OLIVER IMRAY of No 28 Southampton Buildings Chancery Lane in the
County of Middlesex Patent Agent do hereby declare the nature of my invention
for "IMPROVEMENTS IN CALENDERING MACHINES FOR GLAZING AND FINISHING
PAPER AND SIMILAR MATERIAL and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement :-
-
The present improvements have for their object a better guiding of the paper
while passing between and along the rollers of the calendering machine; and
consist essentially in means for enabling the use of compressed air. or steam for this
purpose.
The paper may be either in sheets or in a continuous web.
I arrange parallel to the rollers and close to the same a set of tubes having
perforations or slits opposite to the rollers. The said tubes are connected to any
suitable blower for forcing a current of air through them, or they are connected
with a steam-pipe for admitting steam or with any other suitable means for forcing
air or steam or other suitable gases through them.
The paper passing from the table a under the first (highest) roller b and having
any tendency to adhere to it is blown off it by the blast proceeding from the
uppermost perforated tube, and is pressed against the second (lower) roller c by the
blasts proceeding from other lower perforated tubes 2, 3, 4.
On the paper passing under the second roller c blasts proceeding from further
perforated tubes 5, 6, 7, 8 also first detach the paper from the second roller and
then press it against the third roller, and this action is continued until the paper
has passed through the entire set of rollers.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
1. The use of compressed air or gases or steam for guiding paper or similar
material between and along the rollers of a calendering machine.
2. The combination of the calendering rollers with the perforated tubes 1, 2, 3,
4, 5 &c.
