ROLLER FOR DALENDEEING MACHINES.
(Application filed Nov. 22, 1899.)
A HORNE YS UNITED STATES PATENT O FICE.
JOSEPH ECK, OF DUSSELDORF, GERMANY.
ROLLER FOR CALENDERING-MACHINES.
SPECIFICATION forming part of Letters Patent No. 682,607, dated September 17, 1901.
' Application filed November 22, 1899, Serial No. 737,923. (No model.)
To all whom it may concern.-
Be it known that I, JOSEPH EOK, a subject of the Kingof Prussia, German Emperor, and a resident .of No. 129 Oststrasse, Dusseldorf, in the Province of the Rhine, German Empire, have invented certain new and useful Improvements in Rollers for Oalendering-Machines, of which the followingis a full and exact specification.
In calendering-machines for polishing and pressing purposes there cooperate, as is known, elastic rollers with hard rollers, because hard-metal rollers cannot be manufactured in such an exactness that a uniform pressure is obtained, whereas the elastic rollers accommodate themselves easily to the smallest irregularities of the metal rollers.
The present invention relates to the elastic rollers used in polishing and pressing calendering-macnines. Said rollers have up to now been provided with a mantle-covering of paper, cotton, cocos fiber, wood-wool, and the like; but as these elastic rollers cooperate in many instances with intensely-heated metal rollers, and as, furthermore, heat is generated in consequence of the great pressure between the cooperating rollers, the paper mantles or cotton mantles or the like of the clastic rollers are strongly affected, and there is thus not only the life of the roller reduced, but there result also a number of other drawbacks that are of a bad influence upon the fabric or stuff upon which the rollers are made to operate.
My invention consists in furnishing the elastic rollers for calendering-machines for polishing or pressing or other purposes with a mantle-covering consisting of asbestos or.
an asbestos preparation, this substance being highly adapted to resist the noxious influence of the heat and there being thus done away with the drawbacks adhering to paper mantles, cotton mantles, and the like with regard to their duration and their uniform action.
Since asbestos and asbestos preparations are elastic-fiber materials, the mantle-coverings produced from these materials fit as easily and exactly to the surface or core of the metal rollers as to mantle coverings of paper, cotton, and the like. Mounting the asbestos or the asbestos preparation upon the roller-core and fixing the mantle-covering upon or to the core may be effected in the same manner as done heretofore with the paper covering or the like of the elastic calendering-roller, there being first produced disks from plates of the asbestos or asbestos preparation and these plates being then provided with a central opening corresponding in size and shape to the diameter and section of the core of the roller. Care should, however, be taken that the asbestos mantle or mantlecovering of the asbestos preparation does not slide upon the metallic core, there being, as is known, but a very slight adhesion between these two substances. An expedient means to prevent sliding is furnishing the metallic roller-core with channels or grooves producing ribs between them, the central opening of the asbestos disks or rings being of course made to correspond to the thus-shaped core.
The manufacture of suchrollers is preferably carried out as follows: Upon a rollercore the surface of which is provided with grooves running parallel to the longitudinal axis of the roller or roller-core are shoved circular disks or rings, consisting of asbestos or an asbestos preparation, and these disks or rings after having been placed side by side, so as to cover or surround the whole mantle-surface of the core, are subjected to a strong pressure acting in the direction of the longitudinal axis of the core. The mantle-coveringthus produced is then finished upon a lathe or the like and finally ground and polished, whereafter it is ready for use.
In order to make myinvention more clear, I refer to the accompanying drawings, in which similar letters denote similar parts, and in which-- Figure l is a side view of a calenderingroller constructed according to my invention, and Fig. 2 is a cross-section in line A B in Fig. 1. I
b is the metallic core of the roller, which, as shown in Fig. 2, is provided with grooves or ribs for securely preventing the asbestos mantle against sliding.
a, is the asbestos mantle or the mantle-cov ering of an asbestos preparation, and a represents disks secured to the ends of the core b, for the purpose of preventing the mantlecovering from moving along upon the core in its longitudinal direction.
Having thus fully described the nature of this invention, what I desire to secure by Letters Patent 0f the United States is In an elastic calendering-roller, the combination with a solid core having straight ribs and grooves extending parallel to the longitudinal axis of said core around the whole of the circumference of same so as to let the said core have a cog-wheel-like cross-section, of asbestos disks having each a central opening corresponding in shape to the crosssection of the core, and being all arranged tightly x5 side by side upon the latter so as to form together an immovable asbestos covering of perfectly uniform resistibility throughout the whole of its circumferential surface.
In witness whereof I have hereunto set my 20 hand in presence of two witnesses.
JOSEPH ECK.
