Fig. 13 is a vertical sectional view on the plane of line 13-13 of Fig. 12.
One of the unsolved, and most mysterious, problems in the art o'f winding paper is the formation of post-winding welts. A web of forward with a solution of the paper will, apparently, have been wound into a=perfectly smooth roll devoid of any defects, but-after the Winding operation is completed` welts will frequently appear in vthe surface `of the roll. These welt'smay'appear within n l fifteen minutes after the roll V1s removed from and extend circumferentiall'y of the roll, -60
usually onl part way around. These welts must not ve confused with wrinkles that develop during the winding operation.
Fig. 8 is a longitudinal section through a portion of a roll in which 1 indicates several 65 ilayers, or convolutions, of the paper on an Fig. 3 1s a fragmentary detail view of'one operation has been completed.
So far as we are aware no one has ever come 76 problem cre-l ated by these postfwinding wel We have found that these welts seldom develop near the end of a .roll of paper, and furthermore, thatv it is only a few of the outer layers that are affected. If these outer layers are removed a smooth roll of paper is found beneath them; but this smooth roll will then, in turn, rform surface welts after'a more or lessshort interval.
We believe these welts can be accounted for in the following manner: from the time the A lpulp in a lpaper making machine is turned initial layer of pulp'is wider than the finished paper. .For instance, it is the custom to so gear each set of drying rolls that they run a little more slowly than the preceding set: but this is a mereapproximation to roughly compensate for the shortening of the web, -and the fact remains that the paper is underr great tension longitudinally and this naturally tends to narrow it slightly. VThe paper passes. from the drying rolls to the calendering rolls and then to the reels and, usually, after that to the Winder under a continued longitudinal 19 strain. If the paper, after that, is slitted and rewound it is again subjected to longitudinal tension. It is our belief that the paper is actually narrowed to a perceptible extent during all these processes and that when it is afterward released from tension it tends to regain its natural width. The outermost convolution of the roll will expand rst and will .usually do so successfully at the ends of the and a fraction inches wide when rewound in f the usual way; and that after running through the Winder, and subjected to our procvms es it will be one hundred inches and a fraction Wide. Evidently, therefore, by the process presently to-be described, we have succeeded in winding the paper in its natural width and have compensated` for the tension created by the pulling .means of the Winder, and, possibly, also for the pulling action to which the paper has been subjected during its previous manipulation in passing to the reels and so forth.
This invention consists Yin the method of subjecting the paper web, while advancing under tension exertedby the winding means, to a lateral spreading action of such amplittude as to bring the paper substantially t0 the natural width it vwould assume if free from tension and in winding, or slitting and winding, the paper while it retains substantially its natural width.
The character of the winding or slitting and winding machine employed may, lof
course, vary widely. In Figs. 1 and 2 isshown aslitting and winding machine of the score-cut surface-rewind type in which 3 indicates a web of paper passing over guide rollers 4 to backing roll 5 and score-cut slitter 6 and thence to surface Winding drums 7 and winding shaft 8.` 9 is the wound material. 1 0 indicates a spreader roll over which the paper passes before itis slitted and wound. In the present instance, this-roll is.
an idler provided with an adjustable brake 11 and having plow-shape grooves 12 in its surface, as indicated .more particularly in Fig. 3. The apex of the plow-shape slots points against the direction in which the pa-l per is traveling as indicated by the arrow in Fig. 3. It willl be understood that the paper in passing under this roller tends to rotate it but that this rotating action is opposed by the brake. In consequence, the
roller travels at a less surface speed than' the web and the plow-shape grooves tend to spread the web laterally thereby restoring it substantially to its natural width. 'lhe spreader roll is so close to the slitting and winding means that the paper does not have an opportunity to contract laterally to any substantial degree before slitting and winding. If the machine, as in the present instance, slits as well as winds, it is important that the paper be spread before slitting since otherwise overlappingl of adjacent slitted web sections will occur because the web sections are wound in alinement with and adjacent each other.
In Figs. 4 and 5, we have substantially the same elements as before, except that here the spreader roll 13-is positively driven by gearing 14 and 15 from the back winding drum. The relation of the parts is such that the roll is driven at a surface speed greater than that of the paper and the apex of the plow-shape grooves points in the same direction as that of the travel of the paper.
In Figs. 6 and 7 there is shown' a second modification in which the spreader roll 16 is rotated in a direction opposite to that of the direction of movement of the paper, this being accomplished by driving said roll from intermediate gear 17 by means of pinions 18 and 19. In this case, the apex of the plow-shape grooves points against the direction of movement of the paper. I v
In Figs. 9, V10 and 11 there is shown a spreader device of a different form from that disclosed in the other views. In Figs. 9, 10 and 1l the numeral 20 indicates a stationary shaft having non-rotating cams 21. Rotatably vmounted upon this shaft is a shell 22 having ball bearings 23. Keyed to this shell are supports 24 and slidably mounted on these supports are bars or slats 25. Each bar is provided with a cam roll 26 engaging in cams 21. It will be understood that, as shell I 22, and consequently bars 25, rotate by reason of the traction exerted by the flowing web or otherwise, the bars will be moved longitudinally by reason of engagement Yof cam rolls 26 with cams 2 1. This spreader roll will occupy the same position in the machine as the spreader roll first described and the parts will be so arrangedthat while a bar is in contact with the web it will move outwardly endwise, and during the time a bar is not in engagement with the web it willrewinding machine here shown is of the type in which the slitted ` web sections 27 ,and 28 are wound on separate winding shafts 29 and' 30. These winding shafts may be of the center wind type but in the particular form here shown two winding drums 31, 32 are associated with each winding shaft. The inlowing web is slitted by suitable means, such as the shear-cut slitters 33, after which the sections pass around separate rolls 34 and 35 whence they are directed to their respective winding mechanisms. In winding machines of this type it is impossible for the slitted web sections to interweave since the winding takes place on separate shafts out of alinement with veach other. It is therefore feasible in a machine of this character to spread the sections after slitting. Accordingly, rolls 34 and 35 may be spreader rolls similar to the spreader rolls shown in the other modifications. In the present instance these spreader rolls are of half length only, the upper roll 34 ibeing supported at one end in framework 36 and at its other end in bracket 37 carried by transverse bar 38, while vthe lower roll is supported at one end by framework 36 and at its other end in bracket 39. Each of these half-rolls is provided with plow-shaped grooves with a central apex as shown. Instead of, or in addition to, rolls 34 and 35 there may be a spreader roll for the unslitted web, and such roll is indicated at 40, the web passing over said roll before it reaches the slitting means. If desired, rolls 34, 35 and 40 may be driven by means of belts 41, 42 and 43.
We claim:
1. The method of preventing formation of post-winding welts in wound paper webs that consists in subjecting a paper web, while advancing under tension exerted by the winding means, to a lateral spreading action, in opposition to the longitudinal tension exerted by the winding means, of such amplitude as to bring the paper substantially to the natural width it would assume if free from tension, and winding said web while the paper re-A tains substantially its natural width.
2. The method of preventing formation of post-winding welts in slitted and Wound sections of paper that consists in: subjecting a paper web, while advancing under tension exerted by the winding means, to a lateral spreading action, in opposition to the longitudinal tension exerted by the winding means, of such amplitude as to bring the paper substantially to the natural width it would assume if free fromtension, and slitting said web and winding the sections thereof while the paper retains substantially its natural width.
