SENIOR, OI PHILADELPHIA, PENNSYLVANIA, ASSIGNORS TO PROUIOB & SCHWARTZ, INCORPORATED, OF PHILADELPHIA, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA PROCESS AND APPARATUS FOR MAKING BATTING AND FEMS Application filed April 18,

This invention relates to a continuous process for making finished batting, or felts, from raw material such as cotton, hair, jute, or other natural or synthetic fibers.

The invention also relates to certain improvements in Garnett machines used in the manufacture of batting and felts, and articularly to a machine capable of hand ing short staple fibers, such as cotton linters derived from the second or third ginnings, which are commonly used in the making of batting of the class em loyed for stuffing mattresses and other upho stored furniture.

Prior to this invention the Garnett machines employed in producing bats from the class of stock above described, owing to several conditions, have had an extremely limited hour production, for example, the maximum output of a single machine has been approximately 150 pounds per hour.

One of the conditions which limited the hour production of this type of machine was the rate of speed at which the conveyor. of the lapping machine, which carries the batting awa from the Garnett machine, could be sa ely operated. This maximum speed has been found to be about 80 feet per minute, which if increased causes the betting to be blown into lumps or to be entirely blown ofi' the lapping machine apron, therefore, the speed of the lapping apron must not exceed the safety point above noted;

The prior art machines for handling cotton and similar fibers of the finer grades, usually consist of two sets of co-operating rollers known to the trade as the preliminary set and the finishing set, while the machines employed in the handling of hair, jute and other fibers of the coarser grades usually comprise but a single set of co-operating rollers.

In the handling of the finer grade fibers the stock is fed to the preliminary set, by a conventional type of weighing feeder de signed to place a given amount of stock, in a more or less rough, tangled, and lumpy state, upon a conveyor which carries the stock from the weighing machine to the preliminary set of the Garnett machine.

Around the periphery of the cylinder, which for ordinary purposes is usually ap- 1929. Serial No. 356,118.

proximately 20 inches in diameter and operated at about 250 R. P. M., is arranged a series of relatively small workers, for example, each worker roll is about four inches in diameter and the number of workers in a preliminary set is usually five. These workers are usually operated at about 4 R. P. M.

The workers are usually so arranged with respect to each other that the successive workers strip the fibers from each other and lay them back on the cylinder. Co-operating with the last worker of the series is a stripper roll provided with the usual form of teeth and adapted to strip the fibers from the last worker and lay them back upon the surface of the cylinder.

Following in succession, after the workor stri per, is a fancy roll which is provided with t e usual form of teeth and rotated at a relatively high speed, about 950 R. P. M., being of a diameter substantially twice that of the relatively small workers.

A stripper roll, usually about the same size as the relatively small workers, is provided adjacent the fancy roll for the purpose of stripping the fibers, which may have been picked up by the fancy roll, from the said fancy roll and laying the fibers back on the bodv of the stock carried by the cylinder.

The partially formed bat is then transferred from the preliminary set to the finishing set by a single dofiing roll operating at about 23 R. P. M., which picks the stock from the teeth of the cylinderof the preliminary set and carries the same to, and deposits it upon, the'surface of the cylinder of the finishing set, a stripper roll'being provided in the angle formed between the periphery of the transfer doifer and the pe riphery of the cylinder of the finishing set, which strips the fibers from the teeth of the transfer dofl'er and lays them on the cylinder of the finishing set.

The finishing set is usually composed of a cylinder of substantially the same diameter and operated at about the same rate. of speed as that of the preliminary set: and a series of workers of the same diameter as those of the preliminary set is provided around the periphery of the cylinder, however, in

the finishing set there are usually four of these relatively small workers. operating at about 1; R. l )L. which are followed by the usual worker stripper. of the same relatively small diameter. a fancy roll. and a fancy stripper of the character and relationship previously described with respect to the preliminary set.

The stock is removed from the finishing cylinder by a single dotling roll of the same general character as that previously described for picking the tibers from the cylinder of the pre iminary set.

The single dotl'er of the finishing set operates at about 15 to 20 R. P. \L. and picks the fibers from the cylinder of the finishing set and deposits them upon a single eonvcyer. which carries the bat thus formed from the Garnett machine and transfers it to the apron of the lapping machine.

Attempts have been made to increase the production of the machines by providing weighing feeders of larger capacity and by speeding up the feeder apron so that a greater amount of stock would he forced or crowded into the feed rolls of the tiarnett machine, thereby packing a g:":iter amount of stock upon the cylinder of the machines. The result has been that the increased stock could not be properly iandled by the relatively small workers operated at the relatively slow speeds above noted. and consequently the stock accumulated between the worke 's and the cylinder and was rolled into small balls which in the trade is known as pilling' in order to overcome the pilling of the stock the arrangement of the workers was changed. in both of the above noted types of ma hines. by increasing the diameters of the workers. to increase the relative surface speeds between the workers and the cylinders, and the workers were spaced apart and a separate stripper provided for each worker.

This improved combination of relatively large workers and an imlependent stripper for each of the relatively large workers operated at the greatly increased speeds above noted was successful in handling the increa ed volume of stock and successfully overcame the pilling of the stock at the workers; however. the in reased volume of stock being delivered to the single dotfer of the linishing set caused a pillinp of the stock at and between the said doffer of the finishing set and the cylinder of the finishing set.

The surface speed of the dott'er of the tinishing set. in order to obtain the best results should not be any greater than the maximum surface speed of the conveyer which receives the finishing set bat from the said dotting roll of the finishing set.

\Ve have found. after considerable experiment. that we can successfully handle the increased amount of stock, and to still produce a high-grade hat, by providing, in the finishing set, a single relatively large work er. for example. a worker of appro\iniate|y six inches in diameter operated at the aid .30 ll. P. l\I.. followed by a single t'aney roll of approximately the same diameter a thi single worker and operated at fh'itl ll. l. .\I and a relatively small fancy stripper. a r proximately four inches in diameter and op crated at lit) it. P. .\l.; and by further pro viding the tinishing set with a pair of llllt' tively spaced dotfers operating respectively at about 3.3 It. I. M.. the tirst of which is spaced apart from the fancy stripper bnt fol lows the said fancy stripper in the sequence of operations.

This first dotfer is spaced slightly from the surface of the cylinder of the finishing et and thereby picks up approximately hat i of the thickness of the layer of stock on the finishing cylinder. it being understood that the layer of stock has been previously raised out of the gullets of the cylinder teeth by the preceding single fancy roll. This tirst half of the total thickness of the layer of stock i carried around the bottom of the first doti'er and is removed therefrom by an oscillating comb. which clears the dotl'er and lays the half portion bat or web on a". inclin d conveyer. for reasons hereinafter set forth.

The remaining half portion of the total thickness of the layer of stock which still remains on the finishing cylinder is carried around and removed from the said cylinder by a second dotting roll which is set close to the periphery of the cylinder and thereby removes the said remaining half portion of the stock in the form of a second web. it being understood that this remaining half per tion is raised out of the gullets of the teeth of the finishing cylinder by a second fancy roll positioned intermediate the two dotting rolls.

As is generally known in the art. the fancy rolls are rotated at a relatively high speed. as above noted. which causes current of air to be thrown out front the said rapidly rotat ing roll. Tn order to prevent these current of air from blowing the first, half portion of the layer of stock from the first dotting roll. we provide a pair of wind rolls which are positioned side by side. their centers lying in a plane extending substantially radially of the cylinder of the finishing set and intermediate the first dofi'er and the fancy roll preceding the second dofler. a suitable shield being provided around this fancy roll for preventing the currents of air. created thereby. from blowing the stock oil the conveyer which carries the stock away from the first dotting roll.

Intermediate the second dotting roll and the said second fancy roll a relatively small fancy stripper is provided which clears the aid second fancy roll of any fibers that may he Cat ill)

picked up thereby, and places them back on the cylinder of the finishing set.

The said second portion of the layer of slol'li' when picked up from the cylinder by the second dotting roll is carried around said dotting roll and removed therefrom by a vi- Inviting comb which lays the said second half portion of the layer of stock in the form of a web on a conveyer. which carries the said stock a way from the said second dotting roll.

The two convovers which respectively carry the separate webs formed of the half portions of the total layer of stock are convergent with respect to each other. the delivery end of the conveyer which carries the web from the first dotl'er being positioned above the carrying run of the conveyer which carries the web away from the second dollar. The carrying runs of the respective conveyers travel the same general direction away from the Garnett machine and due to the convergingrelationship of these conveyers, the conrvver carrying: the web formed by the first half portion of the stock lays this said web upon the web formed by the other half por tion of the. stock. which is carried by the see:

This second or underlying ond conveyer. conveyer then carries the re-unitcd webs, which together form the total layer of stock to the apron of an ordinary type of camelhack lapping machine.

The single set machines which handle the coarser grades of fibers are likewise provided with double doifers which function in the same general manner as noted above.

Fig. 2E diagrammatically illustrates a mal'lllllQ of a single set type. showing the double doll'ers and conveyors for separating and reuniting the webs of stock taken off the dollars.

In Fig. 2 of the drawings. the preliminary set of co-o crating rollers is generally illustrated at while the finishing set of co-operating roller's is generally indicated at B. The feeder apron is illustrated at C.

The drawings illustrate the feeder apron C as carrying a batch of raw uncarded stock X and delivering the said stock to and between the feed rolls indicated at 1 and 2 re spectively. These feed rolls 1 and 2 deliver the stock to the lickerin roll 3. A feed roll clearer is illustrated at l which is adapted to clear the feed roll 2 of any of the stock which ma become lodged in the ,lllllL'lh of the teeth of said .l'ccd roll. dcposilin; such stock on the surface of the layer being carried around the lower part of the lickcrin roll 1;.

The lickerin roll 23 carries the layer of stock to the cylinder 5 of the plklllllllull y t-tl A. a lump roll 0' being located in the angle formed between the periphery of the lickerin roll 3 and the periphery of the cylinder 5 of the ireliniinary set A.

The. function of the lump roll 6 is: generally known to the art. its purpose being to catch. break up. and tear apart any large lumps of stock which may be carried by the lickerin roll 3, in order that the saidlickerin roll may deposit the stock on the surface of the cylinder 5 in a fairly even layer.

The cylinder 5. rotating in the direction of the arrows thereon. carries the layer oi stock upwardly. the stock being engaged first by the before mentioned relatively small worker T, which causes a further disintegration of the lumps and starts the carding of the stock carried by the cylinder.

The stock is next engaged by the above mentioned relativel large worker roll 8 which further assists in the straightening out and paralleling of the fibers of which the stock is composed. This relatively large worker 8 also acts to strip the stock from the relatively small worker T returning the stock to the cylinder 5.

C o-operating with the relatively large worker 8 is a relatively small stripper 9 which functions to remove the stock from the worker roll 8' and to deposit it again on.

the cylinder 5.

The stock then passes' to a second rclatirely large worker 10 which further assists in straightening the fibers of the stocl; and completes the ilreliininary treatment of the stock by the preliminary set A.

it relatively small stripper 11 is'provirled V for stripping the stock from the second worker roll 10 and for depositing the same upon the cylinder 5.

Continued rotation of the cylinder 5 carries the stock past a fancy roll 12 which. as above noted. is rotated at a relatively high rate of speed and functions to raise the stock, or to loosen the stock. from the gullets of the teeth of the cylinder In a relatively small fancy stripper 13 being provided for clearing the fancy roll 12 and returning the fibers to the body of the stock carried on the'cylin' der 5. 7

As the cylinder 5 is rotated the stock is eng'aged by the teeth of a single relatively large dotting roll 14 which picks up the entire layer of partially carded stock from the suriace of the cylinder 5 and transfers the same to the cylinder 15 of the'tinishing set l3.-'a relatively small stripper 3-l being located in the angle formed between the periphery of the dofi'er 14 and the cylinder 15 for the purpose of clearing the dofi'er 11 and returning the stock to the surface of the cylinder 15. To successfully carry off the increased amount of stock carried by til. oreliininary cylinder the speed of this transfer dolfer is increased.

In the finishing set B, the stock is acted upon by a single relatively large worker 16 which finishes the straightening and paralleling of the fibers of the stock, the layer of stock bein then in condition to be removed from the irarnett machine.

Continued rotation of the cylinder 15, of the finishing set B, carries the stock past the first fancy roll 17 of the finishing set. This fancy roll raises the layer of finished stock out of the gullets of the teeth of the cylinder 15 and thereby prepares the stock to be subsequently acted upon by the first dofi'er 18 of the finishing set B. a relatively small fancy stripper 19 being located intermediate the fancy roll 17 and the dofler 18 for the purpose of clearin the stock from the fancy and returning the fibers to the cylinder 15.

The doft'er 18 is set a little distance away from the periphery of the cylinder 15, consequently this dotfer 18 picks up but about one-half of the total thickness of the layer of stock carried on the cylinder 15. This half portion of the stock, of web. which is indicated at 00 is carried around the underside of the dotfer 18 and is removed from the teeth' of the dofl'er 18 by a vibrating comb 20 of ordinary construction. This half bat or web .1. is deposited on an inclined conve er 22 of ordinary construction common to arnett machines.

The remaining half bat or web indicated at 1' remains on the surface of the cylinder 15 and is further drawn out of the gullets of the teeth of said cylinder by a second fancy roll for subsequent removal from the said cylinder by a second dotting roll 25, a relatively small fancy stripper 24 being positioned intermediate the second doffer 25 and the second fancy 23. This second dofi'er 25 is set in close contact with the periphery of the cylinder 15 and removes all of the remaining fibers from the cylinder 15.

The web or half bat m is carried around the lower side of the second dofl'er 25 and is removed therefrom by a vibrating comb 26, also of ordinary construction. Upon being combed from the doffer 25 by the vibrating comb 26 the half bat m passes onto an inclined conveyer 27.

The inclined conveyer 27 carries the half but or web 11 under the lower end of the conveyer 22 which is carrying the half bat or web a" from the first dofier 18.

The web 00 passes from the conveyer 27 onto the inclined apron D of an ordinary lapping machine and the web m passes from the conveyer 22 onto the top of the web as, the two webs w and :0 thereby uniting to form the full compit bat X or. the apron l) of the lapping inachln;

The construction just descrillcll successfully eliminates the. pilling of the increased volume of stock at the dotfers by splitting the finished bat into two layers on the finishing cylinder and carrying these two layers away from said cylinder independently of each other, the two layers, half hats, or webs, being re-united at a distant point which is comnton to the planes of travel of the two discharge conveyers 22 and 27.

By this construction the previous maximum output of a single Garnett machine handling the class of stock above referred to is increased from the above noted 150 pounds per hour to approximately 400 pounds per hour without necessitating a movement of the delivery conveyers at a greater speed than the above mentioned rate of speed which is considered safe in the handling of such ma- .terial.

As shown in Fig. 2 of the drawings, a pair of wind rolls 31 and 32 are positioned side by side with their centers lying in a plane extending substantially radially of the cylinder 15 intermediate the first doffer 18 and the second fancy 23, for the purpose of preventing the currents of air created by the fancy roll 23 from blowing the stock forming the half bat m from the dofi'er roll 18 and a casing or bafile 33 is placed around the fancy roll 23 to prevent the said currents of air created thereby from blowing the stock forming the half bat m from the conveyer 22.

Fig. 1 of the drawings diagrammatically illustrates a weighing feeder F; a Garnett machine G; and a lapping machine L arranged in line one behind the other in a manner to carry out our improved process for making battings or felts.

The weighing feeder F is of the type shown and described in the U. S. patent to \Villiam F. Bokum, one of the inventors named in the present application, No. 1,660,219, dated February 21, 1928; and the lapping machine L is either of the type shown and described in the U. S. patent to the present applicants \Villiam F. Bokum and John H. Senior, No. 1,554,838, dated September 22, 1925, or of the type shown and described in U. S. Patent No. 1,517,945 to the same W. F. Bokum and J. H. Senior, dated December 2, 1921.

The improved process primarily consists of continuously and uniformly feeding raw stock to a Garnett machine, splitting the layer of stock on the cylinder of the Garnett machine into a plurality of independent webs, removing the independent webs from the cylinder independently of each other, reuniting the webs at a point removed from the Garnett machine and running the re-united webs through a lapping machine, to complete the formation of a nlulti-layer bat.

\Vhile the process as described above successfully takes care of the increased amount of stock fed to the Barnett machine, the increased rate of speed at which the relatively 7 stock does not have an opportunity to become packed in the gullets of the teeth of the workers.

As shown in Fig. l, theraw stock is de-' livcred by the weighing feeder F to the Garnett machine G uniformly and continuously,

quantities of the stock being weighed and dumped at intervals in the feeder apron C.

The feeder apron C delivers the stock X to the Garnet-t machine which cards the stock in' the manner above noted, the layer of carded stock being split while on the cylinder 15 and removed from the cylinder as a plurality of independent webs m and m by the dofi'ers l8 and 25 respectively;

The independent webs as and as are reunited at the point as which is spac'ed'apart from the Gz rnett machine properx T he united webs then pass onto the apron l) of the lapping machine L, bein' passed from the upwardly inclinedjpion' I to the downwardly inclined apron Eof the lapping machine.

As shown and described in the above mentioned lapping machine patent, the lower end of the apron E moves back and forth across a platform or otherconveyer H, laying or lapping the united web :2 in a series of superposed layers 2?, to form a complete bat.

If desired, especially in the batting of the coarser fibers, the double set Garnett machine G may be replaced by a sin 'le set machine G" shown in Fig. 3, which inc udesa'single cyl-j' inder 35, a series of relatively'large workers as, 39, 40, 41, with their attendant strippers 42, $3,4 5: and 45,3 pair of doffers 18a and 25a, a pair of fancy rolls 17a and 23a. f 7' Conveyers'22a' and'27acarry the separate ebs away from the dofl'ers 18 a and 25a in the manner above noted, 7 r

In the construction shown in Fig. 3, the cylinder 35 is of a greater diameter than the cylinders 5 and 15 of the tandem set machine shownin Fi. 2, for the purposeofaccommodating the increased names cf 'large'workers around its periphery In the single 'set sesissehsea in Fig. 3, the rigid 'feeth er the several rollers and the cylinder-are of a relativelyfcoairser pitch'than those of the tandem machine shown in Fig. 2, the latter being' us'ed with the liner fibers, while the former is used for the coarser fibers.

Obviously the layer of stock on the cylinder of the Garnett machine may be split into more than two, or into a plurality of independent Webs which are respectively removed by independent doli'ers and rc-nnited after being drawn away from the cylinder, Withoutdeparting from the essential features of the invention.

. fancy rol in said finishing set adjacent said relatively large worker, a fancy str'i per in said finishingset co-o crating with; t e said fancy roll thereof, a rigid toothed doifer-following said fancy stripper in said finishing set and adapted to remove a layer of combed fibers from t e cylinder of the finishing set inthe form of a web, a second rigid toothed dqfler s aced apart from the first said doifer in said finishing set and adapted to remove the remaining fibers from the cylinder of the finishing set in the form of a second web; a fancy roll intermediate said doffersin said finishing set, a pair of converging conveyrs for receiving the Webs from said doffers respectively and uniting the webs at a point remotely situated with respect to the said doffers, a pair of wind rollspositioned side by sidein a plane extending substantiall radially fromthe main cylinder of the finishing set intermediate the first dcifer and the fancy roll located between the doiiers, a fancy stripper co-operating with the last said fancy and located betweensaid fancy and the last said dofl'er, and a wind shield extending around the last saidfancy' roll from a point adjacent the said wind rolls to a point adjacent the last said stripper.

10. In a Garnett machine, the combination of a cylinder providedlw-ith rigid teethon its peripheral surface for combing fibers, a plurality of doffer rolls spaced apart around the gylinder and respectively provided with rigid teeth on their peripheral surfaces, said doffers bein ada ted t9 remove successively portions of t e unitary web of said fibers from said cylinder as independent webs, a plurality of conveyers adapted to receive the independent we 5 from said dofl'ers respectively, said conveyers converging and being adapted thereby to unite said webs at a point remotely situated with respect to said cylinder, a fancy roll recedin each of said doffers for raising t e fibers from the gullets of the teeth of said cylinder for subsequent engagement with the teeth of the dofi'ers, and a wind roll positioned intermediate one of said doifers and the fancy roll preceding the 11. In a Garnet-t machine, the combination of a cylinder provided with rigid teeth on its peripheral surface for combing fibers, a plurality of dofi'er rolls spaced apart around the cylinder and respectively provided with rigid teeth on theirperipheral surfaces, said dofl'ers being adapted to remove successively portions of the unitary web of said fibers portion of the from said cylinder as independent webs, a plurality of eonveyers adapted to reeeire the independent webs from said dotl'ers respeetively, said eonveyers converging and being adapted thereby to unite said webs at a point remotely situated with respect to said cylinder, a fanex' r011 preceding each f said doll (rs for raising the fibers from the gullets til. the teeth of said cylinder for subsequent engagement with the teeth of the dollers, and a predetermined number of wind rolls positiuned side by side intermediate one of said dull'el's and the fancy rolls preeeding the next. dotfer.
