WINDING-MACHINE.

and useful Improvements in Winding-Ma-' chines, of which the following is a full, clear,v

and exact description, such as will enable others skilled in the art to which it appertains to make and use'the same. This invention relates to machines for coiling or winding continuous strips of material and especially to machines for winding or ceiling a continuous web of paper, cardboard or similar material. 1

One object of the invention is .to produce a machine for eflici'ently winding a web into a compact bundle or roll;

Another object of the'lnvent'ionis the production of a practical mechanism to wind OIfCOil a'web in accordance with the rate of delivery of the web to the mechanism. p Another. object ofthe invention is the production of a simple device to guide the web asjit is coiledsoasto produce a coil in which the edges of the convolutions aline with. each other avoiding projecting portions.

Another object :oftheinvention is the efiicient. production of a tightly-coiled roll.

Another object of the invention is to pro- 1 duce a mechanism of the character described which may be readily manipulatedand'controlled. r

Still another object of the invention is to produce an efiicaciousmachine capable of rewindin' the web into its original form.

Still'ot er objects will be in part obvious or support having a smooth upper surface.

and in part pointed out hereinafter. The invention accordingly consists in the features of, construction, combinations of elements and arrangements of parts which will be exemplified 1n the construction hereinafter set forth, and the sco 'e of the application of which will be in icated in the 7 following claims.

' to Y. the accompanying Referring now art of this specidrawings which form a ficationand in which similar reference characters refer to similar parts throughout the several views, Figure 1 is a side view showing the machine; Fig. 2 is a plan view thereof; Fig. 3 is a detail plan view showing' the gulding and tension device en- Specification of Letters Patent. Patented Nov, 19, 1912 Application filed December 22, 1910. Serial No. 588,701.

larged; Fig- 4 is a side view of the guiding and tension device shownin Fig. 3; Fig. 5 1s a transverse section through the tension' plate showing the shape of the guide bars and the manner-of securing them in position on the tension plate; and Fig. 6 1s a vi ew of the controller roller and its sustaining connections. 7 Although the present embodiment of the unvent-ion is adapted to wind or c'oil'a web delivered from any suitablesource it isespecially useful in connection with a slow and variable delivery such as when a web is delivered from a machine which produces continuous scores thereinl At 1 is indicated diagrammatically a mach1ne' for scoring a web. Said machine comprises feed rollers 22 between which the web is gripped and fed past rotary scor- "ing'rollers 3-3, these latter producing parallel continuousScores 4-4 1n the web. It IS evident that the web may be fed 'to the scoring machine from any. suitable source of supply and in the resent embodiment it is preferred to provi ea roll of web 5 centrally supported upon a shaft journaled in bearings 6 on a suitable frame work 7. As iv the scoring machineocrates the feed rollers 2 draw the web rom the supply roll {rand the web is delivered from the scoring machine to the' winding or coiling mechanlsm.

The frame 7 may he of any suitable con-.

struction but is preferably composed of metallic bars arranged as shown and providing elevated supports for the parts ofthe folding, coiling or winding mechanism as well as for the roll 5. o I

8 represents a preferably horizontal table A bracket 9 secured to the frame supports a comparatively large guide roller 10 near. one end of the table. The web after leaving the feed rollers 2 passes around guide rollers 12 and 13, over a controlling roller 14 hereinafter more particularly described,

thence around the guide roller 10 from which it passes over the smooth surface of the table, thence to the winding mechanism hereinafter described.

As will hereinafter appear the winding mechanism for the web comprises in its preferred form a rotary'drum or roller u n which the web is continuously coiled, an in order that the coil shall be tight and the 20 ries of parallel lugs or rds'20 is formed on es of the-roll free fro P Z-ojecti g per;

tions of the web, a device comprising 'a plate 15 is provided to guide and tension the web prior to its delivery to the winding roll. The .weight of'this plate is determined by the tension desired and it rests upon the web as it passes across the table 8, being removably retained in position by pins or projections 16. extending hpwardly. from the frames 7, and engaging guiding openings in cars 17, projecting laterally from the plate 15. Projecting from either end of the table 8 are arms 18 supporting Web guiding rollers 19 a short distance from the respective ends of the table. The tension device is so constructed and positioned as to serve to some eiztent as a guide for the web inasmuch as the pins 16 will prevent any extreme lateral movement of the web, but in order to provide an accurate guide forthe web, a seor secured to th e' bottom of the plate 15, the bottom edges of said lugs or rods being shaped or beveled to engage the scores of the web as the latter passes over the plate 8, the ends of the bottom edges being curved to readily receive the web. In order to secure the rods 20 to the plate, the latter is transversely slotted preferably near each end and screw threaded pins 21 secured to each rod project upwardly through the slots and are engaged by nuts 22 whereby the rods 20 may be securely clamped to the bottom of the plate and adjusted so as to be transversely disposed corresponding to, the disposition of the scores in the web.

After being operated upon by the tension device the Web passes to the coiling or winding mechanism. In the present embodiment the winding device comprises a horizontal shaft or roller 23 journaledin the frame 7. The shaft or roller- 23 is adapted to be driven in such a manner as to take up the web as it is delivered from the machine which has previously operated thereon. The movement ofthe roller 23 is effected by a gripping mechanism, preferably frictional, which at a proper time is operated to couple the shaft 23 with a motor or driving mechanism. Secured to the roller 23 is a belt pulley 24 adapted to be driven by a friction belt 25. The belt is continuously moved, or driven from a suitable source such as an overhead pulley 26 and under certain conditions passes loosely around the pulley 24 without suflicient frictional contact with the latter to effect any movementthereof. 27 represents a contact roller journaled in a movable frame pivotally mounted at 28 on a standard 29 projecting upwardly from the frame 7. The movable frame for the roller 27 preferably comprises parallel connected bars 30 and 31, at the outer ends of which the roller 27 is journaled, their opposite ends being pivotally connected to the standard 29 as explained. Thebelt- 25 extends between the arms 30 and 31 and the construction is such that the roller 27 is adapted to lie or rest against a ply of the belt 25 and regulate the pressure and the arc of contact between the beltand the pulley 24, this being permitted by the movable framepivoted as aforesaid. The tractive effect of the belt 25 on the pulley 24 is thus governed by the position of the pulley 27, as it increases the arc of contact between the belt and pulley in its inner position or that toward the pulley, and decreases said are of contact in its outer position.

In order to control the contact between the driving belt and the pulley means are provided to move the roller 27 to vary the arc of contact above referred to. Depending from a suitable point located preferably above the table 8 is a vertical frame comprising parallel pairs of spaced guide rods 32 forming slots or guide ways in which the gudgeons 33 of the roller 14 are adapted to freely move. up and down. Eye-pieces 34 loosely surround each gudgeon and are connected by cords 35 and 36' passing over suitably supported guide rollers 37 and 38 to the movable frame carrying the roller, 27 preferably at the outer end of said frame.

up and down in'its guide ways the roller '27 is moved from and toward the periphery of the pulley 24 changing the arc of contactbetween said pulley and the belt 25. A spring 39 is connected at one end to the movable frame of the roller 27 and at the other end to a portion of the frame 7 to positively effect the inward movement of the roller and assist in setting the gripping mechanism 27. i

In operation the supply roller 5 is loosely journaled on: its support 6 and the end of It will be observed that as the roller 14 moves the .web threaded, in this instance, through the scoring machine between the feed rollers 2, thence around the guide rollers 12 and 13, thence over the roller 14 and around the guide roller 10, over one roller 19, and

between the plate 15 and the table 8 from which it passes over the other roller 19 to the shaft or drum 23 on which it iS to be wound and to which the end of the web is.

suitably secured; The main driving pulley 26 being new set in motion, and the scoring attached to; said pulley will also be rotated until the tractive force between the two is .insuflicient' to drive the pulley against the driven, the Web being unwound therefrom to coil the web thereon. The coiling of the web on the drum will result in taking up the slack of the web and in drawing down the roller 14, which latter movement results in a movement of the roller 27 away from i the pulley 24, thus decreasing the tractive effect between said pulley 'and the belt 25 resistance oifered by the tension of the web. Thus the rotation of the drum 23 and the folding or coiling of the web thereon is governed by the. rate of delivery of the web and continuous and automatic operation of the severalv parts of the apparatus is permitted" to deliver and wind up the web. notwithstanding any variations which may occur in the delivery.

It will be observed that the flexible connect-ion" between the controller and the operating mechanism" permits the movements of said parts and eliminates compression strain therebetween, whereby the rise of the controller is resisted practically'by only its own weight, thus doing away with intermediate connections, the inertia of which might interfere with the accuracy of the control of the web.

In the present embodiment it will be noted that the delivered web is threaded around several guide rollers and around the movable controlling roller 14 before it. engages the tension and guiding device. It is obvious, however, that the invent-ion is not limited to the particular construction described and that the'web may be extended directly from the delivery mechanism to the tension device if desired.

It may be desirable to rewind the web into the relative arrangement it had on the supply roll, and the shafts of the spaced reels or rollers 5 and 23 are provided with pulleys 40 and 41, respectively, adapted to be connected by suitable driving belt. \Vhen the web has been wound on the roller 23, its trailing end may be secured to the roller 5, and said roller rotated in the proper direction to rewind the web thereon in its ori 'nal relation thereto. When so operate the controlling roller is maintained in its upper posit-ion by the weight of the roller 27 and its supporting frame, assisted by the s ring 39. Thus the belt 25 is held against t e pulley 24, and the roller 23 continuously and wound on the roller 5 in a manner which will be apparent from the foregoing ex lanation.

Ihus by means of the above described apparatus the several objects of the invention are accomplished in a practical and efiicient manner.

As many changes could be made in the above construction and many apparently widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted asillustrative and not in a limiting sense.

v It is also to be understood that'the language used in the following claims is intended to cover all of the generic and specific features of the invention herein described and all statements of the scope of the invention, which, as a matter of language, might be said to fall therebetween.
