(Cl. 91-48)
This invention. relates to improvements in
means for cleaning rolls or drums, and refers
specifically to the use of a stone, granite or arti
ficial stone roll which is adapted by making rolling
contact with another roll or drum to remove for
eign substances, such as fibre, lint, coating ma
terial, etc., from the surface of said latter roll
or drum.
In our co-pending application for United States
Letters Patent Serial No. 40,150, a machine is
described for coating paper Which is adapted to
carry out the processes of Peter J. Massey de
scribed in United States Patents Nos. 1,921,368
and 1,921,369. In the Massey coating process

bearings are mounted upon opposite standards
coating material is applied by rolls to the surface
or surfaces of a continuously passing web of
paper, the coating material carried by the rolls
being in the form of a continuous, smooth, uni
form film which, in effect, is transferred bodily
20 to one or both surfaces of the web. In view of
the fact that the coating when applied to the web
is in finished condition, in so far as its smooth
‘ness and distribution is concerned, it is essential
that the coating film on the roll surface be smooth
25 and undisturbed or unmarred by any foreign sub
stance. If foreign substances are carried by the
roll prior to the time when the coating material
is applied thereto, said substances in all prob
ability will be embedded in the coating applied
30 to the web. Therefore it is imperative that the
coating roll be maintained in an extremely clean

phenomenon which is inherent in a stone, granite
or artificial surfaceand which is characterized.

ing material and the like adhere to such surfaces

Of course,l it is to be understood that, our in
vention-although particularly adaptable for clean
45 ing coating roll surfaces such as above described,
can be used to clean surfaces of rolls or the like»
used `for other purposes wherein cleanv surfaces
are necessary.
Other objects and advantages of our invention
50 will be apparent from the accompanying drawing
" and following detail description.
The single , _drawing illustrates a diagrammatic
side elevational view of our roll cleaning device.
Re rringin detail to the drawing, I indicates

Roll I may be a coating roll or' the like and may
be adapted to carry a mobile substance upon its _
surface which is adapted to be transferred to thel
whole or a portion of the surface of a continuously
advancing iiexible web 4. Roll I may be adapted
to cooperate with a similar roll 5 which may also
carry a mobile substance upon- its surface which
is to be transferred to the opposite or upper sur
face of the web 4. The web 4 passesbetween
rolls I and 5 at their point of contact. The coat
ing material or other mobile vsubstance may be
transferred to roll I by means of osculating form
rolls 6 which in turn may be contacted by dis
tributing rolls (not shown) which transfer the
mobile substance from a »suitable source of sup
ply (not shown) to the'surfaces of the form rolls 20
6. If both faces of the web 4 are to be treated
or coatedv a similar arrangement may be utilized
with roll 5.
The peripheries of rolls I and 5 move in the
same direction, and in most cases, at the same 25
peripheral speed as web 4. In utilizing our in
vention it is necessary to apply the mobile sub
stance between the point of cleaning and the
point of transfer of the coating to the web sur
face, that is, the rolls 6 preferably contact roll I
on its advancing side taken with reference to the
point of contact with the web.
In the operation of the machine, which com
prises the subject matter of our co-pending ap
plication hereinbefore mentioned,- the ñlms of 35
coating material transferred from rolls 6 to the
surface of roll I are uniformly distributed, smooth
and of compact texture. These films are trans
ferred bodily to the web surface, it being intended 40
that the film upon thev web be as smooth and
uniformly distributed as that on the roll. Con--’
sequently it is essential that that portion of the
surface of roll I to which the films are applied
be as clean and smooth as possible, since any
irregularity such as the presence of fibres, lint
or coating material upon >the roll I over which
the films are applied will appear as an irregu
larity upon the coating applied to the web.
Manyoperations other than the specific ex 50
ample given above require clean, smooth applica
tor rolls. Therefore we do not wish to be limited
to that one specific application of our present
invention since it broadly contemplates the clean
ing of the surface of any r'oll used for analogous '

By the use of the expression “stone roll” as 25
used in .the specification and claims, is meant:
A roll constructed wholly or in part (surfaced) of
stone, granite, rock, artificial stone or rock or
the like.
lWe claim as our invention:

material to a continuously passing flexible web,
and a stone roll disposed in osculating relation

surface of the same.
2. In combination, a roll for applying coating
material to a continuously passing flexible web,
and a substantially dry stone roll disposed in os

roll to clean the surface of the same.
3. In combination, a roll for applying coating
material to a continuously passing flexible web, a
stone roll disposed in osculating relationship with

together or further apart.
Standard ‘I is pro
vided with an oversize aperture 26 so that bush

The arrangement is such that adjustment of '
surfaces of said osculating rolls in contact with

of standards 3 to 1 and hence rolls I to II. If it
is desired to separate rolls I and I I„fiuid under

I for purposes of cleaning or repair.
As a feature of our invention, roll II, or at

70 in substantially all casessaid cleaning rolls carry
a film of water or other liquid upon their surface.
Our cleaning roll may, if desired, be operated in
