making machine onto a winding-roll. Or-. dinarily two or more winding-rolls are employed, and the web is wound first on "one roll and then on another. When one roll has become filled, the web is severed and the newly-formed end-portion is carried over by hand onto another roll. On slow moving machines this means operates satisfactorily,

but on highspeed machines, which run at say 1,000 ft. per minute,'it is impossible to sever the Web and carry the newly-formed end-portion by hand onto another .roll

- quickly enough to avoid a large amount of waste, or the stopping of the machine.

This invention has for its object the provision of means for starting the winding of newly-formed end-portion of the web on an empty winding-roll while the web is being severed usually in a slanting direction, and while the other end-portion, formed by severing the web, is being Wound on a substantially filled winding-roll, so that the winding operation may be continued with out interruption and the usual hand method of carrying-over avoided. r

In carrying out this feature of my invention a winding-roll is supported in a position herein termed its waitingmposition, in

such manner as to admit of a dily movement into cooperative relation with an un der-roll, over which the web of paper is passing at the moment the web is severed, this second position being termed its starting position. The newly-formed end-pontion of the web begins to wind on said roll and as soon as the web has become firmly.

fixed to said roll by-the winding action, the roll 1s moved into another ositionwith respect to said under-roll, this position being termed its running position, where it remalns until the roll has become filled, such movement into running position enabling an empty winding-roll to be brought into waiting position, preparatory, to being upecification of Letters Patent.

being Wound on said roll in its starting position, the filledv roll is removed to enable the next roll to be moved from its. starting to its running position, thus providing for a continuous winding operationlof the web.

To support the winding-rolls in their start- 1 ing and running positions, two separatesupporting frames are prov ded, whlch are moveable with respect to each other, which frames are also constructed and arranged to admit of transference of .a roll from one to the other frame, from its starting to run ning position, and herein said frames are termed, respectively, the starting and running frames. Y

In View of the vfact.that the web occasionally breaks at some part of the machine, means are herein provided to deflect a newly formed end-portion of the web onto and along suitable guiding-means by which it is delivered to the winding-means, said deflecting means preferably including a. for cibly delivered jet or sheet of air or steam. To avoid the necessity of deflecting the newly-formed end-portion at the exact moment it. arrives. in front of the forcibly delivered jet or sheet of air, a chute is pro-' vided down which said end-portion passes, and a cutter-bar is associated with said chute, and the deflecting-means. is arranged at the top of the chute to deliver the jet or sheet of air against the web, to deflect it and cause it to engage-the cutter-bar. by which it is severed and a newly formed endportion produced, and simultaneously deflected onto and along the guidin -means.

Figure 1 is a side elevation o a portion of a papermaking machine having windingmeans for the paper, embodying my invention.

Fig. 2 is a plan view of the same.

Figs. 3 4 and 5 are transverse sectional details of the winding-means in difierent positions.

Fig.6 is a detail of one of the carriers for the winding-roll to be referred to. r Fig. 7 is'a detail illustrating the act of severing of the web of paper.

Fig. 8 is a modification of my invention wherein theweb is taken from a calender instead of from the machine itself.

Referring to the drawings, Figs. 1 to 7, 10 represents a drying-roll or press-roll of an ordinary papermaking machine, which may be the last drying-roll or press-roll of a Fourdrinier machine; .12 a belt associated .therewith; 13 a blade pivoted at 14:, and

held in engagement with said roll 10 by a 'weight 15, said blade serving to direct the web of paper 16 downward into a chute 17,

under certain conditions of the operation of the machine. 18 is a stationarily supported cylindrical or. other-shaped bar extended transversely from side to side of the machine and arranged between the roll 10 and the chute 17,.in front of the blade'14. The web engages-and is drawn forward beneathsaid bar in its progress to the winding-means and passes'through the space between said bar and, blade when passing to the chute.

Another stationarily supported Cylindrical bar 20, like the bar 18, is arranged in front of and in parallel relation with said bar 18, and preferably at a lower elevation. A series of bars 21 are attached at their ends to the

bars

18 and 20, respectively, said bars 21 being extended longitudinally of the ma chine and arranged in parallel relation with narrow spaces between them. As the bar 20 is arranged below the plane of the bar 18,

is passing downward into the chute, it may be deflected, in a direction toward said guide,

. as represented by dotted line, Fig. 1, and

- chute, said pipe having a plurality of.per-

held in engagement therewith and moved along thereon'to the-winding-means.

As a means to deflect the web at the top of the chute,'I may employ air-forcing; or

steam-forcing means of any suitable kind by which numerous jets of air or steam or a sheet of air or steam, or its equivalent, may be projected against the web, and, as here shown, a pipe 25, which maybe. 'con- .nected with any suitableforein -device, is

arranged'at the side of themachlne, having a horizontal pipe 26 extended transversely of the machine at or above the top of the .forations or one or more'slits, for the issuance of air or steam, wh ch passes over and or otherwise projected roll in running position.

in starting across the top of the chute, beneath the blade 14, and forcibly engages the web and'defiected, and by pressure against the toothed ed e of said ar it is severed, thus to form a ee end-portion which is blown against the guide and moved along thereon. This means of severing the .web to form a new end-portion and to convey it to the Windingmeans is provided purposely in case of a break happening to the web at some part of the machine, and as such happenings are of frequent occurrence, provision of some means becomes necessary, particularly in high-speed machines. It will be observed that this means is automatic in action and does not require any great amount of skill on the part of the operator, it only being necessary to turn on the air, although it is drical roll extended transversely of the machine, and arranged in front of the bar 20 of the guiding-means to receive the web therefrom, and serves as the under-roll. Two rolls are employedupon which the web is to be wound, which are represented at 31 and 32, and said rolls are designed to be successively brought into cooperative relation with said under-roll 30. The

rolls

31 and 32 each have journals 34 arranged in boxes 33, the journals extending through the boxes and projecting therefrom a short distance. These boxes are held against longitudinal movement on the journals. In addition to these rolls, any number of spare rolls, SlIIlllarly constructed, may be employed.

Two separate supporting frames are provided for the winding-rolls, one arranged to receive the boxes and hold a winding-roll in starting position, and the other arranged to receive the journals and hold a winding- Said frames are so constructed and arranged relative to each other that the winding-roll which is arranged in the starting-frame and held by 1t position may be automatically transferre whichthe starting-frame may be returned by hand and an empty-roll placed therein, in readiness to be moved into engagement with the under-roll 30.

The'starting-frame for holding a winding-roll in starting position, as here shown,

consists of a pair of like sectors 40, arrangedat'opposite sides of the machine and pivover which the web is drawn when thus deto the runningeframe, after oted at 41 to side-frames 42'of the main frame-work, said pivots being eccentric I- to the axis of the under-roll 30, and ar- ,ranged above said am. Said sectors have ran I naaaeaa toothed edges 43, concentric totheir pivots 41, arranged for engagement with plnions 4:41, on a shaft45, extended transverselyin sectors on their pivots, and thereby move the winding-roll supported by them into a wait ing-position, see-Fi 1, where it is freefrom contact with the r0 1 30, and then into starting position, see Fig. 3, wherein it engages the roll or the'web thereon; and turning of the shaft in a direction toward the right, 0p crates to move the winding-roll into running position, see Figs. 4 and 5.

The running-frame consists of a pair of upright arms 50, secured to a transverse shaft 51, extended from side to side of the ma chine and having a hand-wheel 52 for turning it. The extremities of said arms have open boxes 53, adapted to receive the journals of a winding-roll. Turning of the shaftin a direction toward the right, operates to move said arms into a position to receive a winding-roll, see Fig. 3, and said arms are moved in the opposite direction by the accumulating paper on the roll, see Figs. 5 and t.

In beginning the winding operation an empty winding-roll 31, will be moved into cooperative engagement with the underroll, and the free end-portion of the web from the delivering means will be passed into the bite of said rolls. Said free end portion may be deflected against the guiding-means by a blast, and thus guided into the bite'of said rolls, or it may be otherwise brought into such position. In any event the rolls will engage the free end-portion and draw it along, and when said free endthrough a short are.

portion emerges from the other side-0f the rolls, it will bedeflected or reversed by a blast or other means, back onto the surtace of the empty winding roll, and preferably held thereon while said roll rotates a few turns. As soon as the web has been wound several turns on the winding-roll so as to become firmly fastened thereto, said starting-frame is moved counter-clockwise to bring the journals of said winding-roll into the recesses 53 at the ends of the arms 50 of the running-frame, as represented in Fig. 4, the boxes 33 being caused to slide outward and the winding roll being moved bodily The web continues to be wound on said winding-roll, and as it'accumulates thereon and the roll increases in diameter, the boxes bearing said roll are caused to slide farther outward, and such sliding movement continues until the boxes leave their recesses. The journals of said roll are then supported solely in the recesses at the extremities of the arms of the run- -winding-roll with said roll in running posi- 'ning-frame, asrepresented in Fig. 5. The

paper then continues to be wound on said roll until the roll isfilledorthereabout. While the paper is being wound on the tion, the starting-frame is returned to its -waiting position, and an empty windingroll is placed therein, preparatory to being moved into starting position. When the rolllon which the paper is being wound be- "comes filled, an empty roll, which is at such time supported by the starting-frame in waiting position, see Fig. 1, will be moved into starting positon, into engagement with the moving web on the under roll, and will be rotated thereby, and temporarily the moving web will passbeneath the rotating empty roll while it is being wound upon the -other roll. -With the two winding rolls in these positions, the web is severed, at a place between them, by any suitable. means, such as a nozzle 60, arranged to forcibly deliver a jet of air, steam, or water beneath the web on the under roll, at a point between said rolls, see Fig. 7. the line of severance being in a slanting direction owing to the move ment of the web. While the web is being thus severed, the newly-formed end-portion is deflected by the jet onto the empty roll, and is wound upon said roll, and the other end-portion is wound upon the filled roll. By this construction and arrangement, the operation is continuous. Then the filled roll will be removed from the running-frame by any suitable ineaus, such as a block and Mitt tackle, and said running-frame will be returned tothc position shown in Fig. 3, preparatory to a repetition of the operation.

To limit the movement of the runningframe it may have an arm 65, secured to its shaft which extends downward, and the lower end-portion of said arm arranged for movement between limiting-stops 66, 67.

; In lieu of taking the web of paper from a paper-making machine it may be taken Ht) from a calender, as represented in Fig. 8, wherein 70 represents the lower roll of a calender.

It will be observed that the windingmeans is essentially automatic. and is especially adapted for high-speed machines wherein it is very difficult to sever the web, and cause a newly-formed end-portion to engage another winding-rollquickly enough to prevent interruptions of the travel of the web.
