KARL SIEG, OF PHILADELPHIA, PENNSYLVANIA, AS SIGNOR 'I'O SAMUEL M. LANGSTON (10., 0F CAMDEN, NEW JERSEY, A CORPORATION OF NEW JERSEY mum wmnsn Application filed August as, 1931. Serial 1%. 559,445.

. This invention relates to winding machines of the type in which paper or other material in web or sheet form is wound on a roll supported by a pair of parallel driven drums and pressed down by a superposed driven roller.

l uppermost, may be wound with said surface faizling either inwardly or outwardly on the r0 In the ordinary drum win'der, it is customary to rotate the drum which brings the paper on to the roll, at a slightly lower speed than the second drum in order that the proper tension may be put on the material andthe roll will be hard and solid without maintaining high tension on the material as delivered to the machine.

Afurther object of the present invention.

is to provide simple means whereby the relative speeds of the two roll supporting drums are automatically varied in accordance with the direction of rotation thereof, whereby the second drum with which the material comes in contact will rotate faster than the first drum, irrespective of whether the material be delivered to one drum for winding the sheet with one surface outermost, or to the other drum for winding the sheet with the said surface innermost. v

' A further object of the invention is to'prov ide simple mechanism for reversing the direction of the drums without reversing'the direction of the slitting or edge trimming mechanism, or the direction of feed of the sheet through said mechanism.

In the accompanyingdrawings, there are shown for the purpose ofillustration, two forms'of the present invention, and in which Fig. 1 is a front elevation of the machine partly in section.

Fig. 2 is a section taken on line 2-'-2 of Fig. 1, certain of the parts being shown somewhat diagrammatically.

' Fig. 3 is a section taken on line 3-3 of Fig. 1. I

Fig. 4 shows one'of the gears associated with one of the winding drums, and having a unidirectional clutch for driving it.

Fig. 5 is a section taken on line 5-5 of Fig. 4, and

Fig. 6 is a view showing another form of gearing for reversing the winding drums.

Although the invention is illustrated in a type of machine particularly adapted for the winding of paper, it should be understood that it is also applicable to the winding of any suitable Web material. although for the sake of conciseness I will hereinafter refer only to paper as the material being operated on, it is to be understood that Therefore,

by the term paper I include any suitable Langston Patent 1,488,126. In this type of machine, the paper is drawn from a paper making machine'or any other suitable source,

slit into sections, and trimmed at the edges and wound. The'machine illustrated has a pair of end frames 10 connected together by a base 11 and by suitable cross-braces, one of which is shown as an I-beam 12.

The paper A is fed over an idler 13, under a second idler 14, and through a suitable slitting mechanism which, in the form shown,

includes a driven shaft 15 having shear cutters 16 mounted thereon, and a series of coacting cutters 20, each mounted on a shaft or rod 17 carried by a bracket or carrier 18 adjustable endwi'se to vary the overlap of the cutters, and mounted on a stationary shaft 19.

The cutters 16 and 20 together with the brackets or carriers 18 may be adjusted lengthwise of their respective shafts 15 and 19 to any desired position in accordance with the desired width of slitted strips, and the width of the sheet, and the cutters 20 may be swung into and out of engagement wit the paper by loosening and turning the bracklit) ets or carriers on the shaft 19. This general type of slitting mechanism may be adapted for slitting paper into sections, or it maybe used merely to trim the side edges of the paper. This particular type of slitting mechanism forms no part of the present invention, but is merely described as constituting a part of a machine in which the present 1nvention may be used to advantage.

The paper after passing through the sl1tting mechanism, passes in contact with an idler 21 and then in contact with one of a pair of positively driven winding drums 22 and 23. The paper A is threaded to follow the course indicated at A or A in accordance with the direction of rotation of the drums, and the surface of the paper which is to be outermost on the roll. The paper is then wound on a mandrel 24 to form a roll C. This mandrel 24 has a vertically guided movement in a plane between the two winding drums 22 and 23, and this movement may be facilitated by counterbalancing members more fully shown and described in the Lang ston patent above referred to.

Above the roll of paper C is a pressure or riding roller 25 which has a vertically guided movement, and which is positively rotated,

.for instance, by the mechanism also shown in the Langston patent above referred to. In a machine of this type, the rollers 22 and 23 are positively rotated, the roll which first engages the paper as it isapplied to the roll, being so geared as to have a lower peripheral speed than the second winding drum, in order that the proper tension and pressure rubbing action may be put on the material, and the roll be tightly formed without maintaining high tension on the paper as it is delivered to the machine.

So far as the main operation and relative positions of the parts so far described are concerned, these are well known in the art.

All of the positively driven elements so far described are driven by a common drive.

Therefore, if it is desired to change the direction of winding of the paper, the mere reversal of the drive in an ordinary machine would not serve to automatically vary the relative speed of the two winding drums in accordance with the change in direction of the paper. Furthermore, this reversal of the drive will cause the reversal of the slitting mechanism, which may be of a type which will only operate in one direction.

As an important feature of the present invention, means are provided whereby the direction of rotation of the drums may be reversed, and whereby the relative speeds of the two winding drums 22 and 23 are automatically varied in accordance with the direction of rotation thereof, so that the second winding drum with which the sheet of paper comes in contact will always rotate faster than the first winding member, irrespective of the direction of feed of the material to the roll. I

In the form illustrated, there are employed a pair of bearing posts 31 and 32 mounted at one side of the machine, and having journaled therebetween a drive shaft 33 which may have mounted thereon a suitable drive pulley 34. A clutch 35 is provided for starting and stoppin the machine, and has its driving member dreyed on the shaft 33, and its driven member loose thereon.

A gear 46 is provided for meshing with and driving gears connected to both drums to rotate them in the same direction, and between this gear 46 and the driven member of the clutch, there is provided driving gearing of such a character that the gear 46 may be driven in forward or reverse direction in respect to the direction of rotation of the shaft 33. In the specific form of gearing illustrated, there is provided a shaft 38 'ournaled between the frame structure 0 the machine and the bearing post 32. This shaft 38 may be connected and drive the cutter shaft 15, and may be driven by a gear 36 secured to the driven member of the clutch, and a gear 37 secured to the shaft 38.

For driving the gear 46 from the shaft 33, there is provided a shaft 30 in alinement with the shaft 33, and the gear 46, and journaled in the bearing post 32. On this shaft 30 are a gear 40 and a bevel gear 41. .The latter meshes with a bevel gear 42 mounted on a shaft 43 journalled in a pair of hearing posts 44. Aligned with the bevel gear 41 and meshing with the bevel gear 42 is a bevel gear 45 connected to the gear 46 which has the same diameter as the gear 40, and which is aligned therewith.

The shaft 38 carries a gear 47 which is splined thereon to permit said gear to be shifted from a position in which it meshes with the gear 40 to a position where it meshes with the wide gear 46. The axial position of the gear 47 thus determines the direction of rotation of the wide gear 46. With the gear 47 meshing with the gear 40, the gear 46 will be rotated in one direction, and with the gear 47 meshing with the gear 46, the latter will be driven in the opposite direction.

Various other types of forward or reverse driving gearing may be employed. For instance, the shafts 38 and 30 and gears 36, 37, 40 and 47 may be omitted, and a shaft connected to the driven member of the clutch, extended through the bevel ear 41 to support it. Between the two evel gears 41 and 45, a double acting jaw clutch might be employed to either lock the gear 41 to the clutch driven shaft, and release the gear 45 therefrom, or to lock the clutch driven shaft to the gear 45 and free the gear 41. Other means would be employed for driving the cutter Shaft if the cutters be of the driven The winding drum 22 has a shaft 48' extending-beyond one of the side frame members 10,,and having keyed thereto a sleeve 49. Loosely mounted on this sleeve'49 are a pair of. gears 50 and 51 both meshing with the wide gear 46, and having separate and op osite unidirectional clutch connections with said sleeve 49. These unidirec-. tional clutch connectlons are so arranged that one of these gears while rotating in one direction, will drive the sleeve 49, while the other gear rotating in the same direction idles around said sleeve 49. The winding drum 23 is similarly provided with a shaft 52 which is keyed to a sleeve 53 carrying a air of gears 54 and 55 transversely aligned with the gears and 51 respectively, and

having separate unidirectional clutch enagements'with said sleeve, and also meshmg with the cars 46. These gears 54 and are couple to the sleeve 53 to provide driving connections with said sleeve in opposite directions.

- One. gear of the pair 50 and 51, and one gear of. the pair 54 and 55 have one or two teeth'more than the other gear of the same pair, but this difierence does not afiect their mutual engagement with the gear 46. For

instance, one gear of each pair may have thirty teeth, and the other gear of the same pair may have twenty-nine teeth. Further.-

- more, the two gears (one of each pair) which have the same direction of drive, have different numbers of teeth. Thus, when the gear 46 is rotated in one direction, one gear of each pair will drive its corresponding winding drum, and one drum will go slightperiphery of these gears.

ly faster than the other, and whenthe gear 46 is rotated in the opposite, direction, fthe other gear of each pair will act as a drum driver, and the last mentioned drum will go the faster.

The unidirectional clutch connection for the two pairs of gears associated with the winding drums may be 'of any suitable type, and in the form shown comprise rollers mounted in slots 61 formed in the. inner These slots 61 have an enlarged portion at 62 for loosely receiving these rollers, and a smaller portion at- 63 -whcre the rollers will be jammed between the gears and the sleeve 49, so that said sleeve will be driven thereby. The rollers 60 are urged against the smaller sections of the slots 61 by springs 64 disposed in recesses 65 in the gear. A unidirectional clutch for driving'rotation in the opposite direction would be similar to that shown, but would have the slots 61 extending in the opposite direction, and the position of the springs 64 correspondingly reversed.

In the operation of the mac'hine, the gear 47 is shifted along the shaft 38 to mesh with either the gear 40 or the gear 46 according to the desired direction of feed of the paper to the drums.- When the gear 47 is in mesh with the ear 40 as shown in Fig. 1, the power is transmitted from the drive shaft 33 to the gears 36 and 37, through the shaft 38 to the gear 47, and then to the gear 40, bevel gears 41, 42 and 45, gear 46, and one gear of each of the two pairs of gears associated with the winding drums 22 and 23 to drive both drums, but one slightly faster than the other.

By shifting the gear 47 to the dotted position to mesh, with the gear 46, the direction of the gear 46 will be reversed, this reverse rotation serving to select a different pair of gears on the shafts of the winding drums for driving these drums, the selected gears automatically varying the relative speeds of the winding drums, so that the second drum with pair of winding drums adapted to support the roll of paper being formed, means for rotating said drums in the same direction at different speeds but at a fixed ratio, means for reversing the direction of rotation of the drums, and means for reversing the relative speeds of said drums upon reversal of the direction of rotation.
