' 3 Claims. (01. 242-65) 1 This invention relates-to web reels or winders, particularly those employed in winding a web of paper being formed on a paper making machine I These reels usually consist of a winder drum, a pair of arms for supporting a winder roll in contact with the winder drum until the web has beenattached to the winder roll and the winding operation commenced. Thereupon, the arms aremoved about the axis of the winder drum to effect transfer of the winder roll while the web is being wound thereon by action of the drum to a second pair of arms. The secondv pair of arms serve to support and guide the winder roll until the roll has been completely wound. Inasmuch as the roll issupported and driven bythe winder drum during the Winding operation, the second pair of arms are mounted to permit movement of the axis of the roll away from the winder drum as the diameter of the rollincreases.

When the roll has been completely wound, the web is severed and connected tova new roll then characters designate corresponding parts in all the views.

Figure ,1 is a top plan view of a winder V bodying my invention.

chine shown in Figure l. v

Figure 3 is a View taken on line 3--3, Figure 2. The reel consists of a. suitable framework in- Figure 2 is an end elevational view of the maeluding side members secured tobase plates II, as by screws 12. The side' members H] are mounted in spaced apart relation and a winder drum I3 is arranged intermediate the'side members on a shaft l4 -journalled in bearings I5 mounted on the side members l0 adjacent one positioned in the first pair of arms and the wound I roll is removed from the second pair" of arms' during the initial winding of the second roll. With this arrangement, the reel is operable continuously without necessitating stopping vor slowing down the paper making machine.

It is necessary to quickly remove the wound roll from the second pair of supporting arms in order that they may. be available to receive the succeeding roll on which the web is being wound end thereof. A powerdrive is connected .to the shaft l4 through a coupling l 6. 1 1- Thewinder roll l'l-is provided'with journals l8 which are recessed in the upper forked ends [9 of a pair of .su'pporting-arms-ill. The arms 20 are mounted for rotation on the shaft I4 and are formed with gear quadrants 2| arranged in mesh with pinions 22 mounted on a shaft'123 journalled in bearings 24 on the side members It). A gear I '25Iis secured to one end-of the shaft 23 and immediately after being severed from'the completely wound r011.

The completely wound rolls are relatively large in diameter and run in weight from 1000 pounds to several thousand pounds. Accordingly, when the web is severed from the wound roll and the roll is moved out of engagement with the winding drum, there is considerable momentum to the roll and it continues to rotate in the second pair of supporting arms for a considerable period of time which tends to delay the removal' of the wound roll.

This invention has as an object a web winder reel apparatus including a braking structure which functions to quickly apply a braking force to the completely wound rolls, whereby rotation of the wound roll can be stopped immediately upon severing the web therefrom, and the roll removed from the supporting arms.

The invention consists in the novel features and in the combinations and constructions herev dle30.

meshes with, a pinion 26 mounted on a stub shaft to which is secured a hand wheel 21. 'With this arrangement, the arms 20 are: movable about the axis of the shaft I4 by rotation'ofthe handwheel 21. The arms 20 are locked against movement by lock members 28 mounted on a shaft 29 journalled in the side members] 0 and provided at the front side of the machine with an operating han- A shaft 34 opposite end of the frame. This shaft has affixed to it a second pair of arms 36 also provided at'their upper ends with yoke members 31 pivotally mounted to the arms 36, as at 38, and being adjusted about the pivot by screws 39.

The arms .36 are likewise provided with gear quadrants '40 arranged in mesh with pinions 4| secured to a shaft 43 also journalled in the frame. Rotation is imparted to the shaft 43 by a hand wheel 44 through a gear reduction 45, whereby the arms 36'are moved toward and from the winder drum I3. I

It will be understood that the winder roll IT is placed in the arms 20 when the same are in vertical position shown in Figure 2. The Web 46 is I secured to the roll which is driven by contact with the winder drum l3. During this initial winding period, the rolls l1 rotate in their journals l8 positioned in the forked ends [9 of the arms 20. The arms 36 are moved clockwise to the position shown in Figure 2 and as soon as is journalled in'bearings 35 at the a'linem'ent with the roll ll.

the web, has started to wind on the roll H, the arms 29 are moved counter-clockwise Figure 2, whereby the inner bearing members 48 on roll 11 are positioned in the forks 31 of arms'sfi. ,As the diameter of the roll being wound increases, the arms 36 move counter-clockwise away from the winder drum 13, whereby the journals it of the roll are -moved out of engagement with the forks H? of thearms'29, permittingthese arms to be returned to vertical position for the receptio of the next empty winder roll. 7 I When the roll is completely wound, the arms 36 have been moved to, or toward, vertical position asindicated in dotted outlina'Figure 2. ,Atthis time, the web is severed and started' on. the

is necessary to stop the rotation of the roll. In-

asmuch as these rolls run into several thousand poundsofweight, there is. considerable momenturn and the operators arethus delayedin the removal of the woundrolls 1 a This invention has to doparticularly with a What I claim is: r v
