1 clainis.
This invention. relates to improvements in means for cleaning rolls or drums, and refers specifically to the use of a stone, granite or artificial stone roll which is adapted by making rolling contact with another roll or drum to remove foreign substances, such as fibre, lint, coating material, 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 described in United States Patents Nos. 1,921,368 and 1,921,369. In the Massey coating process 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, uniform film which, in effect, is transferred bodily 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 smoothness and distribution is concerned, it is essential that the coating film on the roll surface be smooth and undisturbed or unmarred by any foreign substance. If foreign substances are carried by the roll prior to the time when the coating material is applied thereto, said substances in all probability will be embedded in the coating applied to the web. Therefore it is imperative that the coating roll be maintained in an extremely clean condition.
Our present invention is particularly directed to the cleaning of a roll such as above described, and the efficacy thereof is dependent upon the phenomenon which is inherent in a stone, granite or artificial surfaceand which is characterized.
in that foreign particles, such as lint, fibres, coating material and the like adhere to such surfaces even if dry, when the same are brought in osculating relation with a roll surface which is to be cleaned.
Of course,l it is to be understood that, our invention-although particularly adaptable for cleaning 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 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 a rlfoi" drum which ismounted upon bearings 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 surface of the web 4. The web 4 passesbetween rolls I and 5 at their point of contact. The coating 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 distributing rolls (not shown) which transfer the mobile substance from a suitable source of supply (not shown) to the'surfaces of the form rolls 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 peripheral speed as web 4. In utilizing our invention it is necessary to apply the mobile substance between the point of cleaning and the point of transfer of the coating to the web surface, 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 comprises the subject matter of our co-pending application hereinbefore mentioned, the lms of coating material transferred from rolls 6 to the surface of roll I are uniformly distributed, smooth and of compact texture. These films are transferred bodily to the web surface, it being intended 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 irregularity upon the coating applied to the web. y
Manyoperations other than the specific example given above require clean, smooth applicator rolls. Therefore we do not wish to be limited to that one specific application of our present invention since it broadly contemplates the cleaning of the surface of any r'oll used for analogous purposes.
Referring again to the drawing, 1 indicates .one of a pair of oppositely disposed standards,
which are pivotally supported, as at 8, to oppositely positioned lugs or bases 9. The upper` ends of the standards 1 carry bearings III which, in turn, support the opposite ends of roll I I. As will be hereinafter described, roll II is adapted to be disposed in osculating relationship with the receding surface of roll I, taken` with reference to the point of tangency of web 4.
Each of the standards 'I is provided with outwardly extending arms I2 whichv are pivotally secured to piston rods I 3. Cylinders I4 are pivotally supported,as at I5, to lugs or bases I6. f The piston rod I3 at each side of the device passes through stufng boxes II in the heads of the respective cylinders I4 and a piston I8 is secured to the end of each of said rods.
In operation, air or other fluid under pressure may be introduced into the cylinders I4 beneath the pistons I8 thereby urging the rods I3 upwardly and tending to rock standards 'I in a counterclockwise direction. Roll II -is thereby urged toward roll I and is maintained in contact therewith, preferably under pneumatic pressure.
It is to be understood, that the piston rod and cylinder, if desired, may be respectively connected to standard 3 and standard 'I whereby inward .inotion of the piston within the-cylinder will Abring the rolls I and II together.
ment of the actuating piston and cylinder mechanism is not shown, but is an obvious mechanical expedient which will be easily understood by, and may be helpful to those skilled inl the art.
A bushing I9 is pivotally secured to each standard 3, as at 20, each of said standards carrying a lug 2I to which said bushing is attached. A bushing 22, having a slot 23 at its end is adapted to be pivotally secured to each standard 1, each standard carrying a pin 24 which passes through each aperture 23. A capstan screw 25 is adapted to threadedly engage each pair of bushings I8 and 22, the threads at opposite ends of the screws being differentially pitched in the same direction or oppositely pitched so that motion of the capstan relatively moves the standards 3 and 'I closer together or further apart. Standard I is provided with an oversize aperture 26 so that bushing 22 may move angularly in a vertical plane.
The arrangement is such that adjustment of capstan screw 25 limits the degree of proximity of standards 3 to 1 and hence rolls I to II. If it is desired to separate rolls I and I Ifiuid under pressure may be introduced into cylinder I4 above piston I8 and the pressure beneath said piston roll I I may be conveniently rocked away from roll I for purposes of cleaning or repair.
As a feature of our invention, roll II, or at least the surface thereof, is constructed of granite, or other form of stone, or artificial stone such as Stonite or the like. We are aware that cleaning rolls have heretofore been used which by means of rolling contact with a second roll have acted -to clean said latter roll. However, 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 the dry state. Further, we are aware that granite, stone or artificial stone rollsvhave. heretofore been used, particularly in the paper making This arrangeindustry. However, their use has been connned to operations othenthan the cleaning of another roll. We `have found that, a stone or artificial' stone roll has the peculiar faculty for picking up loose materials such as fibres, lint, etc. This the surface of roll I may be removed from the surface oi' the first mentioned roll by a scraper blade 28 which may be adjustably mounted, as by means of bolt 29, upon arm 30. Arm 3B, in turn, may be adjustably secured to lug 3| which comprises a continuation of standard 1. Another advantage inherent in the use of a stone roll is that, a metal scraper blade will not in any way detrlmentally affect the surface of the roll, said surface remaining continuously perfect in spite of the continuous rubbing or scraping contact of the blade 28.
By the use of the expression stone roll as 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. y
lWe claim as our invention:
1. In combination, a roll for applying coating material to a continuously passing flexible web, and a stone roll disposed in osculating relationship with said flrst mentioned roll to clean the 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 osculating relationship with said flrst mentioned roll to clean the surface of the same.
