UNITED STATES PATE-Nr- EDXVARD T. STREET, OF BOUND BROOK,'NEWJERSEY,' ASSIGNOR T0 THE RUER-OID OF NEW YORK, N. Y., ACO'RPDRATGN OF NEVI JERSEY orties AUTOMATIC vROLL VJINDIN'GT- MACHINE Application led February 21,1928. Serial No. 256,653.

This invention relates to amachine tor cutting a web or continuous sheet of flexible fabric, particularlyprepared rooting material, into pieces of measured length, and

` f winding said pieces into rolls.`

Prepared rooting materials, ascommonly made, are composed of a layer of rooting telt saturated with bituminous compositions, and surfaced on one or both sides with a harder bituminous composition. In some kcases either one or both of the surface coatings are faced with particles of mineral matter. The material is generally marketed in roll form, each roll containing approximately 108sq. ft. of material being suicient to cover one square, or 100 sq. ft., of roof surface, allowing for the proper amount of lap at the joints. rlhe material is made vin various weights, usually ranging from about 35 lbs. toabout 65 lbs., or even. heavier, per square. The sheet is generally formed of -a standard width of 36 in., although other widths are sometimes employed. In the case of material of 36 in. width, the unwound length of the roll is about 36 feet.

By vreason of the size, weight, and nature of the material lconsiderable difficulty has been experienced in devising a machine that would successfully handle the product and i?? wind it automatically into rolls.

My invention provides a machine that is adapted to operate upon a web of prepared roolinfr material, and at each cycle of Yits operation, to measure a length of the material, cut the measured length, wind .said length into a roll, and deliver the roll.

ther and further objects of the invention will appear from the following description thereof. It is to be understood, of course, 'that modiiications in the details of construction and arrangement of parts may be made without departing from the scope of my invention. Y

A preferred embodiment of the machine is shown in the drawings in Vwhich VFigure l is a conventionalized side elevation of the machine showing the driving snat and driving-mechanism.

"The frameworkl of the machine comprises two

sidepieces

1 and 2 joined together byal crosspiece 3. At one end ot the frame is mounted a roll 4 that guides the web A into the machine.

Referringnow particularlyto Fig. 2', itl will be Aseen that two pairs 'of :teedor draw rolls and 7 8 are supported 'transversely 0n the framework. These feed rolls are'driven ing-a fixed member A11-12, and a vertically Y I movable -member lSf-li. Said clamps serve n to hold the-web fast during the period when the feed is inoperative. Adjacent the clamp 12-14 is a cutting mechanism which includes a fixed transverse blade 15 and a vertically reciprocating blade 16 by which the web is severed transversely so as to cut od the measured length. The cutting mechanism is timed to operate at about the moment when the feed rolls are released from contact with the web and the clamps are fastenedthereon.

The releasing of the feed rolls, fastening of the clamps, and downward movement of the cut-ting knife are controlled by certain devices whose actuation is effected by the rotation of the measuring roll 9. "These devices, which are hereinafter more fully described, include the double-acting spring trip illustrated in detail in Figs. 8 and 9 of the drawings.

The machine is so designed that the linear rate of feed of the material, caused by the feed rolls 5 6 and 7 8 is somewhatV faster than the rate at which said material is rolled up by the roll forming wheels, thus producing slack C. VTo accommodate the slack the machine is provided with two'series of alternately disposed swingable arms 17 and 18, which arms, when swung into horizontal position, form a skeleton platform over which the advancing edge of the material'is fed into the roll forming mechanism. Any suitable means may be provided for swinging said arms in properly timed relation to the cycle of operation of the machine. One form of such means is shown in the drawings and is described hereinafter.

rlhe mechanism for forming the rollsl B comprises a plurality of series of alternately disposed

wheels

19, 20, 21, and 22 by and between which eachlength of material is rolled up into ase/parate roll. I These wheels are driven to'rotate continuously but at a 'slower rate of peripheral speed than the peripheral speed of the feed rolls 5 6 and 7 8. The

wheels

19 and 20 are mounted on

transverse shafts

23, 24 which are journaled in bearings in the

sidepieces

1, 2, of the frame, while the wheels 21 and A22 are mounted on shafts 25, 26 journaled in bearings in the side-pieces of a carriage 27. rEhe carriage 27, which is provided with a counter weight 28, is mounted on rollers 29 that are connected together by straps 30 and ride on the side frame members so lthat carriage may be moved freely endwise. y

In forming the rolls B, the advancingedge of thematerial is led into the roll forming space between pairs of liked guides 31 and 32. The outer ends of the upper guide members 32 are curved upward and their inner ends are enlarged and'formed with concave faces 33. The guides 32 are positioned above certain of the wheels 19`and between the two adjacent wheels 2O.4 Suiiicient space is allowed between the peripheries of said-wheels 19 and the bottoms: of the guides' 32 to perat the same peripheral speed as the

roll forming Wheels

19, 20, 21, and 22.

AAs the roll B increases in diameter the carriage 27 is gradually pushed back by the increased bnlk of the roll. The two sides of the carriage are cross connected, to assure of their uniform movement, by a crossrod 37 carrying a pinion 38 at each end, which pinions engage with racks 39 fastened to the frame sidepieces and with racks 40 secured to they sides of the carriage. l/Jhen the roll n B has been completely formed, the carriage 27 is positively moved back a further distance, by means of mechanism hereinafter described, so as to provide an openingthrough which the completed roll will be delivered or drop out of the machine, after which the carriage is returned to its initial position ready to form a new roll on the succeeding cycle of operation. If desired, any suitable form of conveyor may be provided to receive the rolls as they are discharged from the machine.-l

The continuouslyrotating parts of the machine, comprising the feed rolls 5 6, 7 8, and the roll forming wheels 19, 2O,` 21, 22, are driven by a shaft 41 vwhich extends lengthwise of the machine and is provided with a driving pulley 42 as seen in Fig. 1. The drivingvrshaft is journaled in fixed

bearings

43, 44 secured to the frame side piece 1, and in a sliding bearing 45 fixed to the movable carriage 27. Fixed to said shaft are two

bevel gears

46, 47, and splined thereto is a third bevel gear 48. Gear V46 meshes'with a bevel gear 49 carried on a stub shaft journaled in the frame piece 1, as shown in Fig. 7. This stub shaft also carries a gear 50 that meshes with the gears 51 and 52 which rotate the lower feed rolls 5 yand 7, respectively. The latter gears engage with

gears

53, 54 that turn the upper feed rolls 6 and 8. Gear 47 engages-with a bevel gear 55 which, through an intermediate gear 56, turns the

gears

57, 58 that rotate the

shafts

23, 24 upon which the series of

roll forming wheels

19 and 20 are mounted. In the embodiment illustrated, the intermediate gear 56 also drives a pinion 59 by which the feed rolls 34--34'are rotated. The third bevel gear 48 similarly engages a gear60, and through the train of gears 61, 62, and 63, continuously rotates the

wheels

21 and 22 throughout the in F ig. 1.0. rIhe stub shaft 66 also carries a smaller gear 67 which, through the gear pair 68 and69 turnsthe'gear 70. The gear ratio .and relationship of the parts is such that the gear 70 makes one complete revolution in each cycle of operation of the ma-y chine. Y

71 is a link chain carrying Va lug-72, which chain is driven by Vva sprocket 73 secured 'to the end of the rotating shaft 66. VThe opposite `end of the chain is carriedon a sprocket 74 which is adjustably mounted in a bearing 75 so as to take up any slack. Below the chain, and disposed in the path of the lug 72, isa member or abutment 76 which pro jects from the side of the carriage 27. If desired this member may be adjustable lengthwise of the carriage. The lower portion of said member is formed with ra sleeve 77 that slides longitudinally on a horizontal rod 78 supported on theY frame sidepiece 2. The lug 72 is so positioned and the rotation of the chain is so timed that said lug will engage the abutment 76 when the roll B is completely formed, thereby positively moving the carriage 27 rearwardly a sufficient distance to permit the roll B to drop through the enlarged space which is thus formed betweenthe series of

wheels

19 and 21. When, in its movement with the chain, the lug becomes disengaged from the abutment, the

carriage 27 is quickly'returned to its initial position by means of the spring 79 and the counterweight 28. Nuts 80 are provided to afford adjustment of the tension of the spring.

I shall now proceed Vto describe the mechanism Vfor swinging-the arms'17 and 18, a detailed view of part of which mechanism is shown in Fig. 12. This mechanism is timed to` swing the arms into horizontal position after the measured length has been completely wound up, and to remain in such position a sufficient length of time to permit the fresh,- ly cut edge of the succeeding length to be fed into the roll forming mechanism over the level surface thusform-ed. During the formation of the roll B, said arms 17 and 18 are swung downwardly to accommodate the slack C, as hereinbefore stated. yOperation of this mechanism is controlled by a cam 81 fixed to a -shaft 82 which rotates continuously with the'gear 70. Bearing on the cam is a follower 83 which is carried on an arm 84 having one end pivoted to a iixedsupport 85 and its -oppositeend pivoted to a'slottedV yoke 86. The yoke has a downward extension 87 formed with a tapered lower end 88, whichtaper is forcedagainstthe face of a roll 89 by a spring 90,'as seen in Fig. 10. This construction provides a frictional shock absorber that'takes up the jar when the follower rides off the high point of the cam and the arms 17, 18 are accordingly lowered. Extending upward from the yoke is a rod 91, and extending outward from the rod is a slide 92 in which the upper end of a exible strap93 is adjustably secured. The lower end of said exible strap is fastened to, and wrapped around, a'wheel 94.-. rll`he wheel 94 is xed to an end of the shaft 95 carrying the arms .17, which shaft extends'through the slot in the yoke 86. It will be apparent that rotation of thecam 81 will raise the yoke 86, thus causing the flexible strap 93 to become partially unwound.

from the wheel 94 and thereby turning the wheel contra-clockwise. This turning motion of the wheel raises the arms 17 to horizontal position. Upon downward mov-ement of said arms, the flexible strap 93 is again wound around the wheel 94. Fixed to the shaft 95'is a pulley 96 which is connected by a crossed belt 97 with a companion pulley 98 on the shaft 99 that carries the arms 18. Attached to shaft 99 is a pulley 100 carrying a counterpoise 101. described, any movements of the arms 17 will produce corresponding .movements ofV the arms 18. Y

The mechanism for reciprocating the vknife 16 includes a rock-shaft 102 having fixed thereto two parallel arms 103, one at each side of the machine, to which the knife supportv104 is pivotally fastened by ylinks 105. The knife blade 16 is detachably secured to the support 104, Awhich support is guided for vertical movements in slides106.l The. arm 103 at the left `hand side of the machine, see Fig. 3, has an extended end 107 that engages with the spring det-ent or catch 108 to hold th-e knife in its raised position. When this detent is released, by mechanismV hereafter described, the knife will descend upon and out vthe web. At one end of the rock-shaft 102 is a rocker-arm 109, and hanging loosely on said shaft is a swingable lever-arm 110. Said lever-arm is formed intermediate its ends with a sleeve 111, and is pivotally connected at its lower end, by a connecting rod 112, with By the arrangement justV the continuously rotating gear 70. Supportf ed to slide lengthwise in the sleeve 111 is a rod 113 having one end pivotally connected tothe lower end of the rocker-arm 109. A spring 114 is coiled around the opposite end of rod 113, the endsv of which springl bear against the face of thev sleeve 111 and the adjusting nuts 115, respectively. Obviously,as the hanging lever arm 110 is connected with the gear 70, it will swing toward said wear during halfof each revolution and away from the gear during the Vother half. Now :as the f detent 108 holds the knife 16, and with it the rocker-arm 109, stationary until released, the

forward swingingmovement ofthe -leverl arm will tend to compress the spring 114 against the nuts 115 so that When the detent is released said spring will expand against its opposite abutment 111, thereby assisting in causing the blade 16 to descend quickly. During the return swinging movement of the lever-arm 110, the sleeve 111 bears against the rocker-arm 109 thus positively raising the knife 16 to its initial position. n the meantime, the detent 108 has been returned to position to engage the end 107 of arm 103 so as to again hold the knife 16 stationary until the succeeding cycle of operation.

Movement of the knife detent 108, as Well as release and engagement of the feed rolls and clamps, are effected by the double acting spring device shown in detail in Figs. 8 and 9. This device comprises a bar 116, preferably circular in cross-section, having its middle portion 117 of reduced diameter thus forming

shoulders

118 and 119 at the ends of said portion. he bar is pivotally supported at its ends by two rocker-

arms

120 and 121 so that it may move bodily endwise in either direction. Endwise movement in one direction is controlled by a catch 122 which is adapted to engage an end of the rocker-arm 120 and is limited by an adjustable stop 123. Similarly, endwise movement in the opposite direction is controlled by the catch 124 and is limited by the stop 125. Mountedto slide freely lengthwise on the reduced portion of the bar are two

collars

126 and 127 between which is located a coiled spring 128. Surrounding the collars and spring is a casing comprising a tubey 129 having

heads

130 and 131 threaded. therein at both ends, which casing independently movable lengthwise relative to 'the bar 116. The casing is connected with the gear 70, as seen in Fig. 3, by a connecting rod 132, acting through the lever 110 and connecting rod 112, se asto move to and fro once for each revolutionof said gear. In other words, movementof the casing is continuous throughout the operation of the machine, While movement of the bar 116 is periodic.

Referring now to Fig. 8 it Will appear that as the casing moves from right to left,the casing head presses against the collar 126 and slides said cellar, Vtogether with the spring 128 and collar 127, to the left thus compressing the spring against the collar 127, which collar is held immovable by engagement with the shoulder 119.` In said figure the casing is shown in its extreme left position, and the other parts are shown in their positions just before the catch 122 is tripped or released. N ow the moment said catchis released, the spring 128 will expand thereby driving the bar 116 tothe left against the stop 123 and thus rocking the two

arms

120 and 121 from right to left. On the return movement of the casing the 'operation of the vparts is reversed so that When the catch '124 is released the

arms

120 and 121 Will rock from left to right.

Rocker arm 120 is secured to a'transversely extending rock shaft 133, and arm 121 tofa transverse rock shaft 134. Fixed to shaft 134 is an upright arm 135 vWhich. carries at its end the knife blade detent 108. Vhen said shaft is rocked, the detent is `moved away, permitting the knife to descend. Y. Referring particularly-to Figs. 2, 4 and 5, the rock shaft 134 carries two arms 136 which are attached by links 137 to the movable clamps member 14. The links 137 are preferablyv forked at their upper ends and formed with slots 138 in their sides at the point of attachment to the arms, as seenin Fig. 2, so as to permit a certain amount of vertical free play between the links and the arms. The member 14 is guided for vertical .movementby two rods'139, one fixed to each end of said member, which rods slide in sleeves formed onthe fixed clamp member 12. Coiled around the Vlower end ofeach rod is a spring 140 wl ich may be adjusted by an adjusting nut 141. ber 13 is similarly attached to arms 142 on rock shaft 133. During progression of the web said clamp members are held out of con;

tact with the web, but when the feed is intermitted the clamps are closed down `upon thev web.

To provide for intermediate feed of the web the feed rolls are so mounted that therolls of each pair canbe moved toward and away from each other. Referring to Figs. 6 and 11, for this purpose the ends of the shafts 143 of the lower feed rolls 5l and 7 and of theshafts 144 of'thevupper rolls 6 and 8, are journaled eccentrically in movable

cylindrical bearings

145, 146, respectively, Vwhich bearings are mounted in the

frame side Vpieces

1 and 2. Fastened to each bearing 145 is a strap 147, and to each bearing 146 a: strap 148. The straps are connected by a linkage 149 to the

arms

150 and 151 fixed to the

rock shafts

133 and 134, respectively. On references to Fig. 11, which shows the parts in feeding position, it Will be seen that swinging movement of vthe rocker arms 150, 151', from right to left will turn the

bearings

146, 147 so as to sepaf rate the two feed rolls of each pair and thus intermit the feed. It should further be observed that the

arms

136 and 142, carried on said rock shafts, are simultaneously depressed to lfasten the clamp,

members

13, 14 on the we At one end of the shaft ,152 of the measuring roll 9 is a worm 153 which engages with a worm Wheely 154, asiseen in Fig. 7. The relationship of the measuring'roll and Worm Wheel is such that'said Wheel Will make one complete revolution for each given length of material fed over the measuringroll. The Worm wheel carries a pin 155 thatis arranged The movable clamp memto enga-ge the free end of the bent lever 156, at the completion of each revolution, so as to slide the colla-r '157 outwardly on "the shaft 152. The collar 157 carries a finger 158 which, on the outward movement of the collar, operatively engages the dog 159 soas to trip t .e latter and release the catch 122.v rlhis releases the double acting spring devices, shown in i5` ig. S, for movement in one direction and causes operation of the mechanisms that separate the feed rolls, fasten the clamps, and drops the cutting knife.

The reverse action of these mechanisms is effected by releasing the catch 124 when the spring device is in the position shown in Fig. 9. The release of said catch is controlled by a cam 160, shown in detail inFig. 18, which cam is fixed to the shaft 82 of the gear 70. A cam follower 161 bears on said cam and is connected by

links

162 and 163 with a bell crank 164 that carries the catch 124.

In threading the web through the machine it is necessary to temporarily lift the pressure roll 10, separate the feed rolls and raise the

movable clamp members

13 and 14, so as to permit passage of the web. The pressure roll 10 is supported at its ends on swingable arms 165, which arms are each pivotally attached at one end to a support 166 extending inward from the

frame side pieces

1 and 2. The other ends of said arms are connected by links 167 to a spindle 16S provided with a lever or handle 169 by which said spindle may be turned so as to raise the roll 10. A second lever or handle 170 is provided to separate the feed rolls. rl`his handle is attached to a spindle 171 to which are fixed two arms 172 each operatively connected at its lower end to one of the linkages 149. On pressing down the handle 170, the arms 17 2 are swung from right to left thereby separating the feed rolls. As this motion also automatically closes down the

clamps

13 and 14, means are provided whereby said clamps may be raised independently. These means comprise cams 173 mounted on spindles 174 provided with handles 175. On turning the handles the cams operate to lifL the rods 139, thus raising sain clamp members.
