PAPEB-UNWINDING STAND WITH WATER-COOKED DRUM.

Application filed 'April 18, 1924. Serial 707,403.

In paper making machines, after the paper leaves the calenders at the d end of the machine, it must be gotten into a form that can be readily handled. To accomplish this result, it is generally necessary to trim the edges and slit the. sheet into several strips; and the first step in this process is to wind the paper on a reel after leaving the calenders. The roll of paper is taken and placed in an unwinding or reeling-off stand, preparatory to being run through slitters-and onto a rewinder positioned adj ac'ent the reelin -ofi stand. I

heretofore a great deal of trouble has been '1 experienced with reeling-off stands on account of the excessive friction which has a tendency to burn u the brake friction bands,

thereby causing de ays and repair expenses.

Reeling-off stands have also been provided with means for cooling off the brake mechanisms but such stands have all been of the back gear typemaking a very expensive for a paper making machine. said stand being provided with a water-cooled brake drum and furthermore being of a gearless type ml wherein areel of paper maybe quickly and simply inserted in place and connected with the drum by a-n improved shiftable driving coupler or connector.

It is an object of this invention to provide H5 a. gearless type of a water-cooled unwinding stand for a paper making machine.

It is also an object of the invention to provide a reeling-01f stand wherein a shiftable coupler engaged in the .drum journal is 4-0 adapmd to be readily connected with a reel of paper which is mounted on the stand for rewinding. I

It is a further object of this invention to provide a reeling-off stand wherein the reel of paper may be adjusted on the stand together with the coupler without requiring movement of the brake drum or uncoupling of the friction bands.

It is furthermore an object ofthe invention to provide a paper making machine with an unwinding or reeling-oil stand wherein the reel of paperto be rewound may be set at different angles with respect to the commercial rewinding machine.

It is an important object of this invention pins adapted to be removably engaged .in a

notched end of the spool shaft.

Other and further important objects of this invention will be apparent from the disclosures in the specification and accompanying drawings.

The invention (in a preferred form) is illustrated on the drawings and hereinafter 7 more fully described.

' Figure -5 is a detail view taken on line 5- 5 of Figure 2 with the coupler omitted.

Figure 6 is an end elevation of the reelingofi' stand taken on line 6-6 of Figure 2.

As shown on the drawings: v The reference numeral 1, Flgure 1, ndicates a rewinding machine provided with I trimming and slitting mechanisms 2 adapted to trim the edges and slit the sheet of paper before rewinding of the same on commercial reels. The slitting and rewinding units form a partvof a paper making machine and are located beyond the dryer end of a Fourdrinier. At the dryer end of the Fourdrinier unit, the paper which has been made and after leaving the calender, is 'woundfon a spool or reel. I r

Positioned between the dryer end. of the' Fourdrinier (not shown) and-the rewlnding unit 1 is a reeling-ofi' stand embodying the principles of this invention. The reelingofi stand comprises a pair of pedestals or brackets 3 and 4 having mounted on the tops thereof bearing frames-5 and 6 respectively. Supported in the bearing frames 5 and 6 are bearing'blocks'Z having eyebolts there-v on for engagement by lifting chains to permit removal of a spool or reelfrom the pedestals 3 and 4. A spool or reel cylinder 9 having a roll of paper 10 thereon is removed from the calender winding machine and after having the bearing bloc s 7' engaged on the ournals 11 thereof, the reel cylinder with the aerated by a bell-crank 15 supported on a block 16 slidable in a vertical slot 17 in the pedestal 4. The lower end of the bell-crank 15 is pivoted through an elongated slot 56 to a crank arm '18 mounted on one end of a shaft 19 journalled in bearings on the lower portions of the pedestals 3 and 4. A crank arm 20 is mounted on the Opposite end of the shaft 19 and has an adjustlng screw 21 connected therewith operable by means of a hand wheel 22.

Formed on one end of theyreel cylinder shaft or journal 11 to the outside of the bearin frame 5 is a coupler '23 having a pair of ra ial notches 24 which communicate with are-shaped slots 25. A-connecting bar'or rod 26 is provided having coupling pins 27 radially mounted near one end thereof adapted to be projected through the coupler notches 24 and seated in the slots 25. The connecting rod 26 has a squared head 28 integrally formed n one end thereof and is slidably disposed within-a squared recess 29 formed -within 'a journal 30 integral with a brake drum 31. The innerend of the brake drum journal 30 is closed as illustrated in Figure 3.

Integrally formed on the opposite end" of the brake drum 31 is a journal 32 open at both ends. The journal 32 is supported within a bearing 33 mounted upon the top of a stand or pedestal 34. Rigidly supported on the pedestals 3 and 34 is a frame section 35 havmg a bearing 36 mounted on the top thereof for supporting the brake drum journal 30.

Secured to the outer end of the brake drum 31 is a hand wheel 37 for the purpose of turning the drum and the connector 26 to permit the coupling pins 27 to be removed from the coupler slots 25 through the notches 24.

Engaged around the brake drum 31 is a lined brake band 38, one end of. which is connected to one arm of abell-crank 39. The other end of the brake band 38- is connected to a bolt 40 pivoted on the other. arm of the bell-crank 39. The bell-crank 39 is secured on one'end of a shaft 41 journalled in a bearlng sleeve 42 formed on the frame section 35.

' jects.

Connected to the other end of the shaft 41 is a lever or bar 43, the lower end of which is connected to be operated by a connecting rod 44. The connecting rod 44 extends from the reeling-off stand to the rewinding unit 1 and is connected to one arm of a bell-crank 45 pivoted on the frame of the rewinding unit. The bell-crank 45 has the other arm thereof connected to a control screw 46 which is operable by means of a handwheel 47 engaged on the upper end thereof.

Supported by means of a bracket 48 on the pedestal 34 is a water discharge housing or globe 49 into which the drum journal 32 pro- Projecting into the outer end of a sleeve 50sformed on the housing 49 is an elbow 51 to which a water supply pipe 52 is attached. Connected in the inner end. of the housing sleeve 50 is one end of a water pipe- 53 which projects through the drum journal 32 into the interior of the drum to supply cooling water thereto. A water discharge or return pipe 54 is connected in an outlet sleeve 55 formed on the bottom of the housing 49.

The operation is as follows:

From the breast roll to the ealenders, the manufacture of paper is a continuous process, and afterleavin-g the calenders, the paper is wound upon a reel or spool from which it. is removed and rewound in a form that can be readily handled. A roll of paper from the calender is transferred with the spool 9 to the reeling-off stand with the spool journals 11 engaged in the bearing blocks 7 on the pedestals 3 and '4. The brake drum 31 is now manually turned b means of the hand wheel 37 until the coup erpins register with the coupler notches 24. The connecting rod 26 is then pulled out from the drum journal 30 and projected into the end of the coupler 23' to ermit the coupler pins 27" to be engaged 1n the coupler slots 25 as illustrated in Figure 3. The spool 9 with the roll of paper 1O thereon is thus easily and quickly connected with the brake mechanism through the' flexible joint afforded by the coupler 23 and the slidable connectingrod 26 which carries the coupler pins 27.

The reeling-off stand holds the roll of paper as it comes from the pa er makin machlne. and is adapted to give e paper the proper tension when it is being rewound in commercial size rolls on the rewinder unit 1. The brake mechanism is used to cont rolthe paper tension and the brake band 38 is sub ected to severe service and the speedof the drum. acting within. the brakeband will soon heat up the brake mechanism. To cool the brake drum, water from the pipe 52 passes through the pipe 53 into the drum 31 and serves to The water is permitted to cool the same. pass out of the drum journal 32 into the housmg 49 and is discharged through the outlet pipe 54.

Since the paper from the paper machine does not always wind up the same, it is sometimes necessary to offset or adjust the spool 9 longitudinally. This is done by means. of the vise handle 14 and the screw 13 causing the connector 26 to slide in the drum journal 30 without necessitating any longitudinal movement of the brake drum or ever requiring uncoupling of the brake band.

It sometimes becomes necessary to set the spool 9 at different angles with respect to the rewinding unit. This is done by operating the hand wheel 22 which actuates the shaft 19 and the bell-crank 15, whereby the bearing frame 6 maybe set as desired.

The brake band 38 is adjusted by means of the bell-crank 39 and the lever 43 through the shaft 44 and bell-crank 45. The bell-crank 45 is actuated by the screw 46 operable by nected with the brake mechanism by means of the slidable connector 26, one end of which has the squared head 28 movable in the drum journal 30, while the other end of said connector carries the coupler pins 27 for engagement with the notched and slotted end of the coupler 23 formed on one of the spool journals 11. With the improved coupler mechanism for the reeling-off stand, a paper roll spool may be engaged in place on the stand pedestals or removed therefrom without requiring any uncoupling of the brake band or the like. Breakage and Wear of back gearing is entirely done away with making a reeling-ofl' stand of materially less cost and much simpler in construction and operation. The various controls for adjusting the spool on the pedestals are all conveniently located at or near the front side of the machine.

I am aware that numerous details of construction may be varied through a Wide range without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted, otherwise than necessitated by the prior art.
