vsents a material' economical time, labor and Patented Oct. 18, 1932 PATENT OFFICE HERMAN G. WEBER, 0F SHEBOYGAN, WISCONSIN MARKING ROLL Application filed `Tuly 28,
This invention relates to a marking roll and more particularly to such a device for imparting a design or impression to the fibrousy web produced in a paper-making machine as the web passes therethrough.
It has long been proposed to impart different water marks to paper and similar fibrous webs by such rolls in order to identify the manufacturer and grade of the aper and as a result a great many forms of) marking rolls have come into commercial use.
One form for instance comprises a metal cylinder or roll having stereotypes or electrotype plates secured to this type of roll, however, it is necessary to wrap the roll marking surface with fabric in order to prevent the stereotypes from cutting into the paper web.
ln another form of roll, a rubber marking sleeve is secured to soft, endless rubber bands which are in turn roll or shaft.
Still another type of roll comprises a hard rubber sleeve rigidly secured to a supporting roll, a soft cushioning sleeve secured to the hard rubber sleeve and a rubber marking sleeve vulcanized to said soft rubber sleeve.
Many disadvantages arise from the use of these various types of marking rolls, all of which increase the cost of production of the marked paper and in this way, decrease the overall efficiency of the paper machine.
For example, as stated above, the stereotype form of marking roll must be wrapped with a plurality of layers of fabric, to prevent the type from cutting into the paper web. This wrapping wears after a short time and must be replaced by an entirely new wrapping. This in itself, involves an expense which when added to the time and labor involved in applying the new wrapping, preproblem. The other types of rolls mentioned have a rather high initial cost, and also require considerable expense in removing, renewing and replacing the' marking surfaces therecf. well as replacing theworn rolls in the machine by new or renewed rolls.
l have now constructed a marking roll which can be used to form water marks on anchored to a supporting the surface thereof. In
1930. Serial N0. 471,197.
paper or embossed designs on cardboard, and which has a comparatively low initial cost,
is easily ,and quickly constructed and dismantled and has a marking surface which can be quickly and economically renewed. My 55 marking roll in addition has a high efficiency in use with the press or drying cylinders of any type of paper-making machine and has a marking surface formed of such material as to obviatethe necessity of employing a fabric wrapping around the periphery thereof.
My marking roll, as usually constructed, comprises a metal core having a layer of cushioning material secured thereto, and a marking surface comprising a plurality of resilient marking sleeves freely but snugly mounted on said cushioning layer so as to be quickly applied thereto and removed th refrom.
It is accordingly an object of this invention 7u to provide a marking roll for forming water marks and similar designs on paper and cardboard which has a readily detachable marking surface.
It is a further important object of this invention to provide a marking roll which is relatively cheap, easy to construct and highly efficient in use.
It is a further important object of this invention to provide a'marking roll wherein the marking surface is so constructed' and mounted on the supporting roll as to impress a clear, uniform design on the paper web despite irregularities on the surface ofthe cylinder in conjunction with which it is used.
It is a further important object of this invention to provide a marking roll having a marking surface composed of a plurality of marking sleeves snugly and detachably mounted on and cushioned from a supporting 90 roll or shaft. y
It is a further important object of this invention' to construct amarking roll with a marking surface so mounted on the roll as A to give endwise when the marking surface encounters depressions and other irregularities on the surface of the cylinder over which the paper web moves while contacting the marking roll.
Other and further important objects of this invention will become apparent from the following description and appended claims.
Referring now to thev drawing, .which discloses a preferred form'of my invention:
Figure 1 is a front elevational view of a marking roll of this. invention with parts broken away and parts in section.
Figure 2 is a sectional view taken on line II-II of Figure 1. i f
Figure 3 isa longitudinal sectional View of a modified form of roll with parts thereof broken away.
On the drawing:
The form of marking roll shown in Figures y 1 and 2 is indicated generally by the reference numeral 1 and comprises a hollow cylindrical metal core or support 2 into the ends 3 of which are pressed journals 4. Said journals 4 are retained securely in place in the ends of said core 2 by means of keys or pins 5. Said ends 3 of the core 2 are of less diameter than the body of the core and are threaded as at 3a for a purpose to be later explained.
The periphery 6 of the body portion of the core 2-is surrounded by a cushioning layer 7 composed of a plurality of sleeves 8 of a resilient or cushioning material such as natural or synthetic rubber, rubber compressed cork compositions or the like, cemented or otherwise secured tothe core 2. These sleeves are spaced apart a slight distance at 9 to permit endwise expansion of the same and to thereby obtain a cushioning of the forces acting against the periphery of said sleeves.
While the thickness of this resilient or cushioning layer 7 may vary quite considerably. I have found that a layer with a wall thickness of about 1 to 2 inches produces very satisfactory results.
A second layer 10 composed of a plurality of sleeves 11 surrounds the cushioning layer 7. Said sleeves 11 are made of such diameter as to readily slip over but snugly lit about said layer 7. The layer 10 forms the marking vsurface of the roll and for this reason, each sleevel 11 has an engraving 12 therein Which forms a complete design in itself or cooperates with the engravings in the other sleeves 11 to make up the complete design 13 of the marking surface.
Said sleeves 11 may be formed of natural rubber, synthetic rubber,'compressed fiber compositions or the like. Preferably, however, said sleeves are composed of a recently discovered rubber substitute. This composition is produced yfrom a mixture of a lime compound forming about 50% by Weight of the mixture, certain metallic salts and mineral and vegetable oils and gums. The mixture which is colorless and powderlike in form, is molded under heat and pressure whereby certain chemical changes take place producin a mass physically resembling natural ru ber. -This mass is resilient, elastic, water, oil, gasoline, alkali and acid proof. Unlike natural rubber, it does not deteriorate with age. It is moreover considerably cheaper than `natural rubber.
In order to properly impart the deign or designs carried by said sleeves 11 to the paper web, it is necessary to adjust the various `sleeves with relation to each other and maintain the sleeves in their adjusted relationship. This result is attained by positioning a small pin 14in the cooperating slots 15 of adjacent sleeves 11 to thereby prevent relative movement between the sleeves.
The marking sleeves 11 are retained on the cere 2 by means of a pair of metal Washers 16 and 17 located on each end o-f said core. The washers 16 and 17 are spaced apart by a washer 18 of rubber or similar cushioning material. The nuts 19 and 2O are threaded on each end of the core 2 and bear against the washer 17, thereby placing the washer 18 under compression and forcing the washer 16 against the outermost of sleeves 11:A By use of the above described resilient fastening means, the marking sleeves 11 give when the marking surfaces of the sleeves encounter' pockets or other irregularities in the surface of the roll or cylinder o'verwhich the fibrous web to be marked moves to thus impart a uniform design to the fibrous web.
The marking rolls of this invention are quickly constructed by placing the cushioning sleeves 8 on the core or roll 2, cementlng or' otherwise securlng said sleeves to said core and then slipping the marking sleeve: 11 over said cushioning sleeves. The fastening washers and nuts are then applied and the roll is ready for use. When the marking'surface of the roll wears out or it is desired to change the marking design, it is only necessary to remove the fastening Washers and nuts, remove the marking sleeves and slip new marking sleeves on the roll. Obviously, the time, labor and expense so involved is small compared to that required in accomplishing the same end with known rolls. Furthermore, by the use of the marking sleeves of the composition disclosed, no special engraving tools are necessary in forming the required designs therein.
It will, of course, be appreciated that the marking sleeves may be mounted directly on the core 2 without the use of a cushioning layer, but this construction isfnot to be preferred.
The modified construction of Figure 3 is the same as that in Figures 1 and 2, except that the cushioning layer 7 of slightly spaced resilient sleeves 8 is replaced by a pluralityr of abutting resilient sleeves 30 cemented or otherwise firmly secured to the core 31.
In order to insure the cushioning of the marking sleeves 32 by said sleeves 30, the ends of said sleeves 3() are provided with cut away portions 32a forming when the sleeves 30 are assembled on the core 31, circumferential grooves or recesses 34 underlying the joints 33 between the marking sleeves. Accordingly, impacts transmitted from the marking sleeves to said cushioining sleeves cause the material of said cushioning sleeves betweenv grooves 34 to expand into said grooves and thereby permit said sleeves to yieldingly receive said impacts. l
It can thus be appreciated that I have constructed marking rolls which have great utility in the marking of paper and which are far more eiiicient than known rolls especially as regards the original and operating costs.
I am aware that many changes may be made and numerous details f construction may be varied through a wide range without departing from the principles of this invention, and I, therefore, do not purpose limiting the patent granted hereon otherwise than necessitated by the prior art.
