BEEDY, OI HAMILTON, OHIO, ASSIGNOB TO THE CHAMPION COATED PAPER COMIPANY, OF HAMILTON, OHIO, A CORPORATION 01' OHIO BAPER-WINDINQ APPARATUS Application filed March 15,: 1829. aerial No. 847,888.

the web of paper is wrinkled or cockled.

Under these conditions and also at other times the paper may wind very unevenly, with the production, of permanently creased POItiOHS'lIl spite of'the continuous attention of an operator. This trouble is particularly pronounced with light wei ht coated'papers.

. The object of the invention is to prov de a from the ri reel which reduces or eliminates these difii-.

culties in winding paper.

The invention will be described with reference to the accompanying drawings,- of which Fi 1' is a diagrammatic representation of y in use in the paper-mak- 1 a ree ing assemb in industry;

ig. 2 is a front .,eievation of the improved smoothing 'roll of "the invention;

Fig. 3 is a side elevation of the same; and

Fig. 4 is a verticalcross-section of a portion of the rimof the improved smoothing roll, showing the distinctive features of the invention. I

The invention may employ the same assembly as that shownin Fig.'1. 1 is a web of paper which may come, for examplafrom the drying festoons of a coatin" 'rna hine. It passes around the guide rol 9. to the smoothing roll 3 and then is wound into the roll of paper 4 on the core 5. Smoothing roll 3 is driven from the pulley 6 b means of the belt 7, pulley 6 being connected to a motor or other source of power not shown. The core 5 is keyed to the shaft 8. 9 is a weight which presses down on the shaft 8. 7

It is well known to provide the surface of the smoothing roll 3 with a number of parallel grooves. One series of grooves extends from the le the two series meetin in the middle of the convex surface of t e roll, forming a number of broad Vs. By rotating the roll in the direction of the apex of the V, the paper is spread out from. the cen ter toward the edges. Although this device other, 4 has prove t edge of the roll and another" helps in the production of a well wound roll, it is not always successful'in this.

-The present invention relates to certain improvements in the above described smoothing roll, more particularly shown in Figs. 2, 3 and 4.

A number of grooves 12 are cut in the convex surface of the roll, the arrangement of the grooves being substantially the same as described above.

The cross-sectional View,

Fig. 4, shows the preferred shape of these grooves. The forward face of the groove 13 slopes away from the roll surface at a lowangle. The rear face 14 of the groove forms almost a right angle with the 'roll surface. This preferred shape may be designated as sulcate or furrow shaped. The forward and rear edges of the grooves are smoothed off to prevent tearing the paper.

Each groove is perforated number of small holes 15 extending along each groove. These holes permit the direct passage of air from the roll surface to the interior. In practice, a roll 20 inches in diameter-with grooves spaced two inches apart,

and with circular holes inch in diameter and spaced in the ooves one inch from each d satisfactory.

The reel may be used for coated or uncoamd paper.-

The operation of this device has proved ve successful. The paper'is wound up wit out trouble into a firm, uniform roll, substantially free from creases and other imperfections.

It will be seen that the invention comprises a smoothing roll for reeling webs of paper, the peripheral surface of which is provided with a pluralityof V-shaped longitudinal grooves, preferably sulcate in section, ar-

ran ed in parallel spaced relation, the bed of t e grooves being pierced by a plurality of erforations.

claim:-

1. A smoothin roll for reelin webs of paper the perip eral surface 0 which is provi ed with a plurality of V-shaped longitudinal grooves arranged in parallel spaced relation, the apexes of said grooves extending in the direction of motion of the surface of the roll, and the beds of the grooves being pierced Ely a plurality of perforations, permitting e dllCt passage of air from the surface of the roll to the intenor.

5 2. A smoothin roll for reeling webs of paper, the perip eral surface of which is provided with a plurality of .V-shaped' longitudinal grooves, of sulcate cross-section,

arranged in parallel spaced relation, the

apexes of said grooves extending in the direction of motion of the surface of the roll,-

and the beds of the grooves being pierced by a plurality of perforations, permitting the 5 direct passage of air from' the surface of the roll to the interior.

- In testimony whereof I affix m si ature.
