WINDING MACHINE Application filed July 28,
This invention relates to winding machines of the type known as surface winding machines. and the main object and feature of this invention is to counteract the tendency of the winding shaft, and its accumulated material, to roll or bounce out of the machine.

Fig. 17 is a detail view showing a modified form of the invention disclosed in Fig. 13,
In surface winding machines it is now the custom to wind, at. enormous speeds, very wide webs of flexible material into rolls of considerable diameter. The momentum acquired by the winding shaft and its accumulated material is therefore considerable and there has been found to be an increasing tendency on the part of said shaft and its 1926. Serial No. 125,849.
accumulated material to roll or bounce out of the machine in the general direction of the upper run of the winding shaft.
In Fig. 1 is illustrated diagrammatically one type of surface winding machine in which 1 and 2 indicate two surface winding drums, 3 is the winding'shaft with its accumulated material and 4 is the riding roller which may or may not be used. The direction of rotation is indicated by the arrows; the upper run above referred to being denoted by arrow 3. From this it will be seen that the heavy mass tends to rise over the crestof drum 1 and to move out of the machine. According to my analysis of the behavior of the parts, the momentum above referred to constitutes the chief factor, but there are other factors that will accentuate or in a measure counteract this chief factor. In the case of Fig. 1 web 18 passes over the upper surface of drum 1 and by its resistance, usually accentuated by braking means, to the pull of the winding means tends likewise to lift the roll of material and to pull it out of the machine over the crest of drum 1. Again, it is customary to drive drum 2 at a slightly higher surface speed than" drum 1, and theoretically there should be a certain amount of continuous slippage between said drum 2 and the wound material. This would undoubtedly take place if the material being wound were smooth but itfrequently happens that said material is rough and fibrous, as a result of which a series of bounces rather than a smooth constant slippagetakes place; that is to say: the rewound material actually rises off the surface of drum 2 to compensate for the overspeed thereof. Finally, if a riding or top pressure roll as 4 is employed the tendency, as shown by the arrow, is to increase the urge of the shaft and its accumulated material to leave the machine. Riding roller 4, if used, may be driven by friction of the accumulated material in which case it becomes active as a factor in urging shaft 3 out of the machine chiefly when the machine is slowing down, say when the end of a run is about to be reached. But, if the riding roller is driven by means other than by friction with the paper roll, it is active as a factor all the time.
I have found that the tendency above referred to may be overcome by having the crest of drum 1 at a higher level than drum 2. To distinguish between drums 1 and 2 I have arbitrarily called 1 an outer drum and 2 an inner drum, or drum 1 may be called that drum which is forward of the center of rotation, in the direction of rotation of the upper run (indicated by 3*) of shaft 3. The machine maybe a winding machine pure and simple but, if desired, slitters as 6 of any desired character, such as shear-cut or score-cut slitters, may be employed.
In Fig. 2 the threading of web 18 is somewhat different from Fig. 1 in that it passes first to drum 2 and thence between the drum to the shaft. Here the factors of momentum of shaft 3 and its accumulated material as well as the urge of the riding roll are active. Drum 1 is also active, because, being the last drum which engages the paper, it is driven at an overspeed and this tends to raise the roll of paper, but the resistance of web 18 in this instance, acts in opposition to the other factors. In this case drum 1 is likewise the outer drum and is at a slightly higher level than 2.
In Fig. 3 the arrangement is substantially the same as in Fig. 2. Here web 18 stfikes drum 2 first and then passes between the drums to the winding shaft. Drum 1 is here, preferably, driven at an overspeed; and said drum is located at a higher level than 2. The factors mentioned in Fig. 2 are present in the same manner in Fig. 3.
In Fig. 4 the arrangement is again different. In this case slitter 6 is a top slitter that may coact with the riding roller, and web 18 is led first to the riding roller and then to the winding shaft, striking first drum 1 and then drum 2. Drum 2 is the overspeed drum, and drum 1 is at a higher level than drum 2. In this form of the invention the resistance of web 18 likewise opposes the other factors.
It will be seen from the above discussion that the arrangement set out in Figs. 1 to 4 is the reverse of that shown in Patents Nos. 798,241 and 1,063,093.
Turning now to the actual construction of the machine as shown in the more detailed drawings, 1 and 2 indicate two surface winding drums spaced apart and rotating in the same direction, 3 is the winding shaft and 4 is the riding roller. If the material is to be slitted before winding, suitable cutting means may be employed. As shown in Figs. 5 and 6 these means may consist of a backing roller 5 having a glass hardened surface with which cooperates one or more score cutters 6 of known construction. In some forms of machines the backing roller constitutes one of the winding drums as indicated in Fig. 12. Power is a plied to an extension 7 of one of the win ing drums as by means of pulley 8 or otherwise, and from this eXten sion motion is imparted to the other drum and to backing roller 5 by means of sprockets 9, 10 and 11 and silent chain 12. 13 is a chain tension adjusting means. Drum 2 may be driven at an overspeed either by making it of a slightly greater diameter or by a slightly different gear ratio. Riding roller 4 is here shown as being driven by means of spiral gears 14, upright shaft 15, bevel gear 16 sliding on shaft 15 and bevel gear 17 carried by the riding roller. As in all machines of this type, the winding shaft and the riding roller are displaceable by the accumulating material and are also movable manually in a well-understood manner.
It will be observed from Figs. 5, 6, 11 and 12 that drum 1 is at a level slightly higher than the other drum and that web 18 in this instance is led to the upper surface of the drum which is located at the higher level and then directly to the upper surface of the other drum. In Figs. 5 and 6 the web passes over suitable guide rollers 19, 20 and 21 and then to backing roller 5 after which it passes to the outer and upper surface of the higher drum. In Fig. 11 the web passes over guide rollers 19 and cutters 50 and thence directly between the upper surface of drum 1 and the rewound material, while in Fig. 12 the web passes from guide roller 20 to the under surface of drum 2, then to drum 1 where it is slitted and then over the outer and upper surface of drum 1 to the winding shaft. The location of drum 1 at a higher level than drum 2 may be accomplished in many ways. For instance, it is entirely feasible to take a standard Cameron or other machine and tilt it backwards bodily by means of Wedges placed under the forward side of the framework. This would raise not only the forward drum 1 but would also tilt the guides for the slidable winding shaft and riding roller, and the effect would therefore be the same as in the construction shown in Fig. 5 where the undersurface of the framework is level with the floor and drum 1 is located in the framework at a slightly higher level than drum 2, and where, in addition, guiding members 22 are shown inclined so that both the winding shaft and the riding roller rise at an angle to the vertical or in a line inclined toward the vertical center line of drum 2 located at the lower level. In Fig. 11 the arrangement is exactly the opposite of that shown in Fig. 5 becausethe web is led in from the back instead of from the front of the machine. In Figs. 12 the ar rangement will be the same as in Fig. 6 or it may be like the arrangement shown in Fig. 6, to be presently described.
Referring again to Fig. 5 it will be seen that the paper roll rises in a line that passes from a point between the surface drums, through the center of the winding shaft and through the center of the riding roll. OW-
ing to the location of the riding roller and to the speed at which it moves whether ornot it is driven it will be seen that this roller will have a tendency to push the paper roll from the machine. If we now turn to Fig. 6 it will be seen that guide members 23 for the winding shaft are inclined as in Fig. 5 but that guide members 24 of the riding roll are substantially vertical. The effect of this construction is that as the riding roller rises it is brought increasingly beyond or forward of the vertical center line through the accumulated material. It will now be observed that it is no longer possible for the riding roller to exert any force sufficient to cause any tendency to outward movement of the paper roll. I have employed the words inclined and vertical in regard to guides 23 and 24 but it will be obvious that these are terms of description and not of limitation and that if guide 23 were vertical and guide 24 were forwardly inclined the same result would be obtained. The form shown in Fig. 6 in which several of the inventive features are combined is, with my present knowledge, the most desirable form.
In Figs. 13 to 17 inclusive are shown further modifications of the invention in that the elevation of the drum is made adjustable. As there shown, 51 is a tiltable support whose pivotal center 52 is coincident with that of one of the drums as 2. This support carries the other drum 1 and winding shaft 3 as well as guides 53 to slidably control the winding shaft. Said support also carries intermediate gear 54 for driving drum 1 from drum 2. Suitable means not carried by the support are provided to rotate drum 2, such as gear 55. Riding roller 4 is mounted independently of support 51 as by means of guides 56 on the framework. It will now be understood that if the support is rocked the driving connection of the drums will be maintained unbroken and that drum 1 can be raised more or less. As a matter of fact, when a run is completed, this device can also be used to eject the paper roll by lowering drum I below the level of drum 2. Any suitable means may be used to effect tilting of the support. In the present instance support 51 carries a gear sector 57 with which meshes a worm 58. This worm is carried by shaft 59 driven by means of screw gears 60 from shaft 61 which latter is operated by handwheel 62. The arrangement is in duplicate as shown, one train of connection going to each side of the machine. In Fig. 17 is shown a different method of adjusting the support, an eccentric 63 being employed.
InFig. 14 we have substantially the same arrangement as in Fig. 13 but here web 18 is led in from the back and consequently the drum whose center is coincident with the pivotal center of the support is drum 1.
I claim:
1. A winding machine including: a rotatable winding shaft, and two surface winding drums, spaced apart and rotating in the same direction to support said shaft therebetween and to wind a web of flexible material thereon, that drum which is forward of the center of rotation, in the direction of rotation of the upper run of the shaft, having its crest at a higher level than that of the other drum, and winding shaft guide members to admit of the winding shaft rising, at all times during the accumulation of material thereon, in a line inclined toward the vertical center line of the drum which is located at the lower level so that said other drum increasingly sustains the thrust of the wound material as it accumulates on the winding shaft.
