30 Claiml.

This invention relates to apparatus for winding web or sheet material into. a roll and more specifically relates to machines for winding paper into rolls.

5 It has been customary heretofore to wind paper onto a winder shaft revolved by surface contact through the paper-with a driven under drum.

It has also been proposed to swing the winder shaft and roll, being found thereon circumfer- 10 entially around the winder drum from a vertical position to an almost horizontal position. Such moving of the windet shaft and roll circumferentially around the winder drum relieves some of the weight from the drum lso that, as the Y 16 weight of the roll increasesfthe paper will not lbe wound too tight. Y

i u While these known machines provide for relieving of pressure between the winder drum and the roll, they do not provide for an increase of .lvpressure between the roll and drum above that equal to. or less than that produced by the -dead weight of the winder shaft and roll on the widder drum. According 4to this invention the winder. shaft can be pneumatically or hydraulically forced against the winder drum or moved away 30 from the drum to create any desired pressures and thus make possible the winding of a roll with any desired degree of hardness.

The machines of this invention also provide for individual control -of pressures on opposite ends of the roll to compensate for variations in paper thickness and the like so that a uniformly hard roll can be obtained. Y

The machines of this invention further provide for the transfer of the roll being wound to ini uned tracks without topping :ne winding pperation and without interfering with the pressure between the roll and .the windingV drum. This vtransfer permits the initial holding means to be moved back tostarting position for receiving a new winder shaft therein. Then when the lroll is completely wound this new winder shaft is put into operation without delay to Ireceive the end of the paper cut from. the wound roll.

It is then an object of this invention to prf- A further object of this invention is to provide a paper Winder that can be set to maintain a fixed pressure between the roll being wound and the Winder drum.Y

Another object of this invention isftmprovide 5 a paper making machine having fluid pressure operated jacks controlling the hardness of the roll being wound on the machine. i

Another object of this invention is to provide a paper winder with an individuallyoperated pres- 1o sure control for opposite ends of the roll being wound.-

Another object of this invention is to provide a paper'winder providing for the quick transfer of a paper web from one windet shaft to another 15 winder shaft.

-A further object of this invention is to provide a paper winder capable of winding paper on Winder shafts while regulating the hardness of' the roll being wound independentlyof the weight zo of the roll or winder shaft.

Y A further object of this invention is to provide a paper winder utilizing the bottomn roll of a calender stack as a winder drum and having means holding the roll being'wound against the 25 -bottom roll of the calender stack with any desired amount of pressure.

Other and further objects of this invention will become apparent to those .nues in me art from the following detailed description of the annexed so sheets of drawings.

On the drawings: Figurelisaperspectiveviewofapaper winder machine according to this invention.

paper discharged from the calender relation.

Each frame member I0 has a vhoriaontal top portion iI at one end thereof and an inclined top portion I2 at the other end thereof and above the horizontal portion II. The inclined portion I2 slopes toward the horizontal portion I'I.

The horizontal portions II of the frames Il! have boltedthereon bearing housings I3. As best shown in Figure 4, these bearing housings I3 have a central portion I3e of greater diameter than the end portions thereof.

A supporting member I4 having strap portions I5 and I6 is mounted on each bearing housing I3 with the strap portions I5 and I6 thereof extending around the top half of the bearing housing. These strap members abut the enlarged central portion |311 of the bearing housing and are thus held against ain'al movement.

Complementary strap members I5a and IEa are secured to the strap members I5 and I6 and extend around the other half of the bearing housmgS.

The strap members I5a carry a sector gear I1 Vformed integral therewith. below the bearing housings between the .trame members. y

Each"member I4 provides open ended beai'mgY vyokes I8 and I9 for a purpose to be hereinafter Amore fully described.

' provided by these members can be swung around means of clamping bolts such as 2|.

the bearing housingsfby operation of the sector gears as will be hereinafter described.

The outer ends of each bearing housing I3 A to receive a roll of paper on the spool portion 5I have ring members 20 xedly clamped thereon by Each ring member 20 has an arm 22 extending vertically upward from the topl of the ring members. Logs 23 are bolted to the tops of the arm 22'and are adjustable vertically on said arms by means of adjusting bolts 24.

'I'he bearing h'ousings I3 contain bearings (not shown) for rotatably supporting the trunnions 25 and 26 of a Winder drum 21 disposed between the frame members I0. Y

The Winder -drum 21 has a large diameter grooved wheel 28 seemed to one end thereof for receiving a Sheahan-carrier rope (not shown) bar 32 bolted'to the ngers. The iingers 3| of therearoundto guide or feed the web of paper t0 the Winder drum. The Sheahan carrier is disclosed in the Sheahan U. S. Patent 1,504,727. A

the other side. The longer lingers 3| of each member Il are connected at the top by means of a cross The sector gears are y The bearing yokes I3 and I3 provided by each vmember Il comprise short arms orilngers3l on one side thereof vand longer arms or iingers 3| on armies each member Il provide tracks for a carriage 33 slidable between the fingers 3i. The carriages 33 have bearing housing engaging portions 34 adapted to t between the bearing yokes i@ and I9 for acting on the bearings mounted in said yokes as will be hereinafter described.

Each carriage 33 is secured to the uid pressure cylinder 35 of a double acting hydraulic or pneumatic jack'35.

The jack cylinders 35 are thus slidably supported adjacent the track fingers 3|. A

Each jack 36 has a piston rod 31`extending through the bottom thereot` and pivotally connected by means of a pin 38 to ears 39 formed on the straps I5 and I6 of the member I4 as best shown in Figure 3.

A piston III (Figure '1) is secured to the other` end of the piston rod 31 in each cylinder 35.

As isV customary in double-acting fluid pressure jacks, both ends of each cylinder 35 may be supplied With uid under pressure through exible tubes or hoses 4I and 42. Thus both sides of the piston 40 in the jacks 36 can be subjected to huid pressure for sliding the cylinders 35 relative to the piston since the piston rods 31'are anchored.

Since the( jacks 35 are slidably carried by the fingers 3| of the members I4 and since the piston rods of the jacks are pivotally anchored on the strap portions I5 and I6 of the member Il, the jacks are movable circumferentially around the bearing housings I3 with the, members I4. ,AsbestshowninFigures 1to4awindershaft 50 is mounted above the Winder drum 21. The shaft 50 has a central hub or spool portion 5I of larger diameter than the shaft. The ends of the shaft receive bearing housings 52 in free rotatable relation to the shaft so that the same can freely revolve Within the bearing housings on bearings contained in the housings.

Each bearing housing 52 has two large diameter annular portions 53 separated by a smaller diameter annular portion 54.7 Thebearing housings also have annular collars 55 on the outer ends thereof.

In mounting a Winder shaft 50 in the machine thereof, the members Il are swung about the bearing housings I3 by rotaion'of a hand wheel 56 (Figures 1 and 4) to position the bearing yokes I8 an'd I9 in alignment with the lugs 23. The hydraulic jacks 36 are operated to move the carriages 33 and bearing engagement portions 34 thereof to the top of the lingers 3|. The Winder shaft 50 is then lowered by' means of an overhead crane (not shown) so that the bearing housings 52 thereon are mounted in the bearing yokes I8 and I3. The large diameter annular portions 53 of the bearing housings are adapted to slide in the yokes I8 and I9 along the inner edges of the ngers 3II and 3|. The collar portions 55 ofthe bearings 52 rest on the lugs 23 and the position of these lugs is adjusted to hold the spool 5I in spaced relation above the Winder drum 21.

AsbestshowninFigure 1,abracket51isse cured to the front frame member I I and extends outwardly therefrom: The bracket 51 rotatably supports a shaft 58. The hanwheel 55 is secured to the end of the shaft il.

As best shownin Figure 4,the carries in xed relation thereon a small gear 59 and a. brake drum GII. The gear 53 meshes with a large gear 6I secured on the end of a shaft 52 projecting through the front frame member Il.

drum 21 and has a large diameter hollow portion 62a to obtain high torsional strength for the least amount of weight of the shaft. For assembly purposes, the end of the shaft 62 is joined through a 5 coupler 63 with a short shaft illrotatably mounted in the rear frame member i8. The shafts 62 and 64 have small gears 65 keyed thereon meshing vwith the sector gears I1 as shown in Figures 3 and 4. It is thus obvious that a rotation of the hand Wheel 56 will swing the members I4 around the bearing housings I3.

As shown in Figures 1, 2 and 4, the brake drum 68 on the shaft 58 has a brake band 66 wrapped therearound and secured to frame I0 at one end thereof. The other end of the brake band 66 is connected through a link 61V as shown in Figure 1 to afoot pedal 68 pivotally mounted on a bracket 69 secured to the oor in front of the front frame member I8. Obviously the bracket can be integral with the frame member I8 if desired.

The bracket 69 pivotally 'carries a threaded rod 10 extending through an eye 1I formed on the drum 68 against rotation; However, when the foot pedal 68 is-depressed the eye end 1| of .the

pedal is raised to release the brake band 66 and permit rotation of the brake drum 60. This brake arrangement is desirable to control manual operation of the'hand wheel 56. s

When 'it is desired to start that Winder shaft 59 rotating to .receive paper therearound the iootpedal 68 is depressed and the hand wheel 56 is rotated to swing the bearing yokes |8 and I9 40 for carryingthe bearing housings 52 01T ofthe V lugsv 23. The spool 5| is then in contact with the Winder drum 21. The portions 34 of the .carriages 33 engage the small diameter annular v portions 54 ofthe bearing housings 52 to hold spool portion 5| of the Winder shaft 50 can be urged' against the Winder drum 21 with any de`- sired amount of force by operation of the jacks 36 to move the carriages 33 toward the drum.

"lI'heI Winder drum is then rotated and the end of a Web of paper threadedbetween the spool 5| and the Winder drum and started around the spool. From then on the spool 5I is rotated by surface contact through the paper With the .Winder drum.

f A roll of paper R (Figures 3 and 4) is thus built up on the spool 5|' and this roll R canbe Wound to any desired hardness by manipulation-of the r`jacks 36` tovapply the desired pressure between o .thewmder drum nana the rou. As the m11 R l fr. -builds up on the y Winder shaft it may reach a weightexerting agreateramount of pressure on A:the/wincling drumvvthan isndesiredy.

As shown in v .v Figure 1,the bearing yokesi|8l and I9 receive 70. th'ejenlarged portions 53. of thebearing lhousings 52.` A.,rotationoffthe-hand Wheel 56 toswing ings 52 are adapted to t on the tracks 14 and thev larger diameter portions 53 of the bearing housings provide flanges to hold the bearing housings on the tracks 14. Y

The members I4 have cross bars such as 15 bolted thereon adapted to contact stop members such as 16 shown in Figure 1 for aligning the portions 54 of the bearing housings 52 with the tracks 14. During this lowering operation the jacks 36 hold the roll R against the Winder drum 21 with the desired amount of pressure. The lowering operation is illustrated indotted lines in Figure 3.

As shown in Figures 1 and 5, the tracks 14 have carriages 11 slidably mounted thereon. The carriages 11 support the iluid pressure cylinders 18 of another pair of double-acting hydraulic or pneumatic jacks 19.

Brackets are secured to the ends of the tracks 14 as shown in Figures 1 and 2 for anchoring the projecting ends of piston rods 8| extending from the jacks 19. As shown in Figure '1, the other ends of the piston rods 8| are secured to pistons 8|a in the cylinders 18. Fluid under pressure is supplied to either end of the cylinders 18, so as to act on either side of the pistons 8Ia therein, through flexible tubes or

hoses

82 and 83. The cylinders 18 of the jacks 19 can thus be moved toward or away from the Winder drum 21 depending upon, which end of the cylinder is subjected1 to fluidpressure.

The ends of the jacks 19 facing the Winder drum 21 have brackets' 84v secured thereon. Wheels 85 are rotatablymounted on the brackets 84 in spaced relation and are adapted to contact the portions 53 of the bearing housings 52 fora purpose to be hereinafter more fully described.

The carriages` 11 for the hydraulic jacks 18 have arms 86 bolted thereon and extending toward the Winder drum 21. Asbest shown in Figure 5, the arms 86 are provided with eye ends 81. Link members 88 are pivotally carried on the ends of the arms 86 by means of pins 89 extending through the mid-portions of the` links and the eye ends 81 of the arms. The lower ends of the links are Weighted as vat 90 vto hold the links in vertical position. The top. ends of the links rotatably carry rollers 9| adapted to contact the collars 55 of the bearing housings 52 as Willbe more fully hereinafter described.

As shown in Figures 1 and 3, the eye ends 81 of the arms 86 have abutment members 92 on the under sides thereof cooperating with -stop members 93 on the'links 88 to prevent a tilting of the upper half of the links 'towardthe'winder drum 21. However the links are free to tilt in I the-other direction'sol that when the arms 85 are advanced under the bearing housings onV under'the collars 55 ofv thev bearing housings;

It should be noted that the wheels 85 straddle the bearing housing engaging portions 34 of l thev carriages 33 so that the pressure between the roll and the Winder drum is not released when switching from the jacks 36 tothe jacks 19. The jacks 36 can then be released from the bearing housings on the Winder shaft and when the roll builds up to move the bearing housings out of the bearing yokes I8 and I9, the members I4 can be rotated back to vertical position. 'A new Winder shaft is then mounted on the lugs 23 with its bearing housings 52 seated in the bearing yokes I8 and I9. In the meantime the first roll continues to build up while supported on the tracks 14 and anydesired amount of pressure of the roll on the Winder shaft can be maintained by operation of the jacks 19. If the roll, dueto its own Weight, and the incline of the tracks 14 exerts more pressure against the Winder drum 21 than is desired, this pressure can be relieved by the reverse operation of the jacks 19 as will be more fully hereinafter described.

Since the roll mounted in the bearing yokes I8 and I9 may attain an appreciable weight and may be hard to handle during the lowering operation t0 the tracks 14 a counterbaian'cing device is provided to resist this downward movement of the roll and to make it possible, with the aid of the brake device previously described, to stop the roll at any desired position on the periphery of the `winding drum between the top of the drum and the tracks 14. This counterbalancing device is villustrated in Figures 4 and 6 of the drawings.

- The lower end oi the toggle member |0| :is pivotally coupled by means of a coupler |04 to one end of a cable |05 trained under a pulley 06 at the base of the machine and over a second pulley |01 spaced laterally and above the pulley |06. The other end of the cable is. attached to counterbearing yokes VI8 and I9 for carrying the Winder shaft'and roll thereon to the tracks 14 the countcrweight |08will be eii'ective to resist this movement witha force proportional to the distance of the yokes from the vertical. l v

"When the members I4 are rotated in the opposite' direction to bring the empty bearing yokes Il 'and I9 back above the Winder drum the counterbalance willbe effective to aid such movement only until the toggle reaches a vertical position. A further rotation of the members I4 to bring the yokes .into alignment with the lugs 23 will cause the toggle member |0| to pivot about the pin |02 and the oilset portion |03 will merely move away from the strap |6a.

The pairs of uid pressure jacks 36 and 19 are I operated through'valves as shown in Figure '1.

'Ihe jacks will be described as'being actuated with compressed air although it should bef'understood that other uid means under pressure, suchas oil, can be used in place of air.

Asshown in Figure 7, numeral I0 designates 'a main supply pipe for compressed air. A branch pipe communicating with the pipe ||0 supplies air to the air inlet. ||2 of a. four-way valve I I3 controlling the operation of the jacks 36. A

.spring pressed valve I I4 is interposed in the pipe line I| I between the air inlet M2 and the main 1 supplyline i I0. Ifhis valve ||4 is normally closed but is adapted to be manually opened by manipu- 53 lation of a handle I|5 thereof.

A by-pass pipe line ||6 is provided around the valve II4. This by-pass pipe line |I6 contains' f a pressure reducing 'valve ||1 and an indicating gauge H8.' The pressure reducer-H1 is adjust- 1o two pressure outlets H9 and$|20 vand a bleeder 15 vent |2I open tothe atmosphere. The pressure outlet ||9 of the valve ||3 receives a pipe line |22 communicating through branch pipes |23 and |24 with the exible hoses 4| in communication with thetop ends of the jacks 36.

' The pressure outlet |20 receives a pipeline |25 communicating through branch pipes |26 and |21 with the flexible hoses 42 entering the lower Y ends of the jacks 36.

The valve ||3 has a core or rotor |28 (Figure 8) adapted to be manually rotated by means of an external lever |29 (Figure 7). The core |28 of the valve I I3 has two passageways |30-and |3| therethrough for communicating with the various 30 v inlet and outlet ports of the valve as shown in Figure 8.

When it is desired to lower the cylinders 35 of the-Jacks 36 the valve ||3 is rotated'to position the passageways therein as shown in Figure 8. 35

pressed air to the lower ends of thejack's forces 45 the cylinders 35 downwardly since the pistons 40 are anchored through the piston rods 31 against movement. 'I'his downward movement of the cylinders brings the engaging portions 35 of the` carriages 33 into contact with the bearing housings 52 for forcing the spool 5| against the Winder drum 21. f

When-it is desired to raise theA cylinders the valve 3 is manipulated to vent the lower ends yof the cylinders with the atmosphere and to sup- 55 plyv compressed air to inders. l

With the pressure reducing vvalve I|1 set to supply the desired pressure to the valve II3, itis the upper ends of the cylobvious that the jacks will maintain this uniform Y pressure against the Winder shaft. The reducing valve ||1 can be varied to increase or lessen the pressure as desired during the winding operation-i When lit is desired to quickly move'the -jack cylinders 35 such as when disengaging the same 65 from the bearing housings on the Winder shaft after-the bearing housings have been deposited on the tracks, the full pressureof the supply line |.I0 can be conveyed to the jacks without changing the setting ofthe reducing valve by merely 70 opening the. spring pressed valve ||4. The valve is readily opened by manually depressing the hand Il5 to overcome the spring pressure of the v ve.

A second branch pipe m also communicates At the same time the 40 A navales with the main supply une no. The pipe m has a four-way coupling 131- thereon which coupling 'receives by-pass pipe lines 130e and 130b as well as a pipe |32. The pipe 132 is connected to a normallyaciosed spring retained valve |33 that can be opened by manual manipulation of a handle |334. 'I'he other aide of the valve receives 'a pipe 134 connected to a T 135.

The by-pass pipe lines |30a and 1301 have variable pressure reducing valves |36 and |31 respectively therein and are connected to four-Way coua four-way valve 141.

plings |38 andv|39 respectively. Pipe lines 140 and |41 respectively join the-T |35 with the

couplings

138 and 139. Check valves 142 and |43 are mounted in the pipe lines |40 and 14| respectively.

These check valves open to permit air passage 'I'hc four-way coupling |39 receives a pipe line 148 having a pressure indicating gauge |49 at the end thereof. The coupling 139 also receives a pipe |50 connected to the inlet side of a four-way valve 15|. The valves |41 and 151 are similar to the valve 1 13 described in Figure 8 and include two pressure outletsand a bleeder vent.

One of the pressure outlets of thevalve |41 receives a pipe line 152 connectedA through the ilexible hose 82 to the lower end of the jack 19 at the rear side of the machine. This end of the jack faces the Winder drum 21. The other pressure outlet of the valvev receives a pipe line .153 connected through the hose 83 to the other end of said jack at the rear side of the machine.

The valve 15| receives a'pipe |54 in one of the pressurel outlets thereof. The pipe |54 is connec'ted through the hose 82 to the lower end of the jack 19on the frontside of the machine. This end of the jack 19 faces the Winder drum 21.

'I'he other pressure outlet of the valve |51 receives a pipe |55 connected through the flexible hose 83 to the. other end of said jack 19 on the front side of the machine.

In operation of the 'jacks 19 the pressure reducing valves 136 and 131 are set to maintain a desired amount oi pressure supply to the valves |41 and 15| as indicated by the gauges |45 and 149. Air will thu's flow from vthe supplyline 110 throughthe by-pass lines 130a and 13017 into the valves |41 and 15|. Since the valve 133 is normally closed vand since the check valves |42 and |43 do not permit passage from the by-pass lines to the valve 133, the .valves 141and |51 will receive air pressure inV an amount determined by the. setting v "of the reducing valves. The valves 141 and 151 can then bemanipulated to supply this air pressure to either end of the Jacks .19 for sliding the jack cylinders toward or away from the Winder drum. Since each jack 19 has `a separate control valve |41 or 15.1 the jacks can be separately operated and permit the forcing of oneend of the roll on the tracks 1'4 against the Winder drum to exert more pressure on the drum than the |10 through the valves' |41 and 15| to the Jacks.

This spring valve 13 3 thus permits a rapid operation of the jacks without disturbing the setting ot the pressure reducing valves. Such rapid operation may be desirableto bring the wheels 85 of the jacks from spaced relation to the bearing housings 52 into voperative contact with the bear# ing housings and alsoto bring the rollersl from spaced relation to the bearing housings into contact with the collars 55 of the housings.

In the modified form of the machine accordingto this invention shown in Figure 9v the Winder drum 21 is the last roll of a stack of calender rolls 100, 18|,v |82. In Figure 9, parts identical with the parts of the vmachine described in Figures 1 to 8 have been marked with the same reference numerals.

In the machine shown in FlgurevQ, the side frame members suchas 10 have horizontal tops for receiving the tracks such as 14' on which the hydraulic jacks 19 are slidably mounted. The

sure between the rolls. The web after leaving the roll 162 passes around the Winder/ drum 21 and is Wound into a roll R. on a- Winder) shaft 50 having the bearing housings 52 described in Figures 1 to 8 rotatably secured to the endsthereof.

The roll R is held against the Winder drum 21 by the hydraulic jacks such as 36 acting on the bear--V ing housings 52 which are slidably mounted in the bearing yokes such as 18.

As the roll R,builds up, the bearing yokes are swung downward by rotation of the'members 14 as described in Figures 1 to' 8 and the bearing housings 52 of the Winder drum 50 are deposited on the horizontal tracks such as 14. The hy- -draulic jacks such as 36 hold the roll against the wlnder drum during this lowering operation.

The jacks such as 19 are then brought into operative engagement with the bearing housings 52 in the same manner described in Figures 1 to 8 to hold the roll R against the Winder d rum.

The jacks 36 are then released from the bearing housings 52 and the bearing yokes such as 18 can be swung upward for receiving a new Winder shaft therein. The roll R continues to build up while supported on the tracks such las 14' and when it reaches a desired size the new Winder shaft is placed into contact with the Winder drum 21 in the same manner described inFigures 1 to 8.

In this modification of the machine, therefore,

the wi'nder drum is utilized as the last roll of a calender stack and the paper is Wound into a roll as it issues from the calender stack. :The

paper roll being wound can be held against the Winder drum with any desired, amount of pressure and this pressure can be maintained during the transferring of the roll from the bearing yokes to the horizontal tracks. i

From the above descriptions it'should be understood that the Winder drums 21 of machines according to this invention receive paper webs W (Figures 3 and 9) therearound. The paper lwebs are then Wound around Winder shafts held in pressure relation to the Winder drums by means of fluid pressure operated jacks. As the rolls are built upon the Winder drums the samev are lowered, While being held against the drums with any desired amount of pressure,-and are deposited on tracks .or Ways. additional set of rol jacks is then brought into operation to hold the rolls deposited on the ways or tracks against the Winder drums. These jacks do not interfere with the operation of the rst used jacks and the maintenance of the desired pressure between the roll and the Winder drums can be transferred fromone set of jacks to the other set without releasing the pressure. This is accomplished by specially designed bearing housings on the ends of the Winder shafts which have .a small diameter portion engageable with the rst sets of jacks and-large diameter portions engageable with the second set of jacks. The second set of jacks straddle the bearing housing engaging portions of the first set of jacks.

When the rolls, on the tracks, build up to a size sumcient to move the bearing housings of the Winder shaft out of the bearing yokes I8 and I9, these yokes can be rotated back to their initial positions abovethe Winder drums for receiving a new Winder shaft therein. This Winder shaft is held in spaced relation from the Winder drum on supporting' lugs 23 until it is desired to place the new Winder shaft into operation. At

this moment the web being Wound is cut as by means of an air slice, directed around the new Winder shaft and the new Winder shaft moved .into contacting position with the Winder drum by swinging the members I4 so as to move the bearing yokes I8 and I9 away from the supporting lugs 23. A

Any desired amount of pressure can be maintained between the roll being wound .and the Winder drum during all operations of the machine. If it is desired to relieve the pressure between the roll being wound and the Winder drum,

.the jacks 19 can be operated as described above to pull the roll on the tracks 1I away from the Winder drum.

The swinging of the roll from its initial starting position on top of the winding drum to a position alongside of or below the winding drum can be readily edected by a single operator by manipulation of the hand wheel 56 and the foot pedal 68. The counterbalancing device described in Figure 6 prevents the roll from dropping too drum and operable on the ends of theawinnder fast or getting away from the operator during the lowering operation. The brake arrangement described in Figures 1 and 4 permits the stopping of theroll at any point on the Winder drum during the lowering operation. Y
