METHOD OF AND APPARATUS EGR TRANSFERRING CARDED MATERIAL.

Application filed 9,

My invention relates generally to the art of carding and for its object to provide an improved method of. and apparatus for. transferring carded materiahsuch as wool, cotton, or other staple from one carding machine to another.

In Patent No. 1,610,209. issued to me on December 7, 1926. there is shown and described a method of, and apparatus for. transferring carded material, which is characterized by the distribution of the cardings from the doifer cylinder of the first machine to oppositely moving receiving aprons which blend the cardings into web for transferal to the feed table of the second carding machine. As set forth in my above mentioned patent the cardings a-re'distributed obliquely with re spect to the oppositely moving receiving aprons, whereby the cardings are gatheredinto a web. the edges of which are thinner than at the middle thereof. so that when the web is laid on the receiving table of the second carding machine adjacent folds are in nesting relation. In operation, the apparatus of-my aforesaid patent is adapted to form a loose web without substantial. disturbance of the parallel relation of the fibres. so th atquality of the staple is preserved when the web is acted on bv the second card. and means are also provided for varying both the width and thickness of the web to meet varying condi-. tions of operation and quality of staple.

According to the presentinvention. 1 provide a carding apparatus that operates on.

somewhat the same general principle as the apparatus shown in my aforesaid Patent No. 1,610,209. the apparatus of the present invention being particularly characterized by its compactness and adaptability to meet conditions where the space bet-ween the ends of adjacent carding machines is limited. In the apparatus of the present invention. the cardings are take directly from the doffer cylinder and distributed uniformly upon oppo-. sitely moving aprons which build the cardings into a web of uniform cross-section through their cooperation with gatherin rolls located opposite the center of the doifor cylinder and below theaprons; The web i s then conveyed, without twisting. to apoint immediately above the receiving table of the second carding machine.

By my invention, width and thickness of 1953?. Serial No. 182.408.

the web is adapted tobe controlled through very simple adjustments of the receiving aprons and their. associated gathering rolls, and the entire apparatus is characterized by the fact that the distance which the cardings have to travel in being transferred from the doifer cylinder of the first machine to the feed table i1 I of tnesecond machine, 1s reduced to a minimum, all as will hereinafter more fully appear with reference to the accompanying lmilding them intoa web.

' Referring first to Figs. 1 and 5, a portion P I e or the first carding machine lsshown at A and comprises a main card cylinder land a doffer cylinder 2 which is adapted to strip the carded fibres from the main cylinder 1. One end frame of the carding machine is indicated at 3 and a shaft 4 is rotatably supported by the frame 1 with its axis parallel to the axis of the doffer cylinder 2. The shaft t provides number of fingers 5 for carrying a dofiing knife 6' and the shaft 4 is adapted to have an oscillatory movement imparted thereto which will cause the knife 6 to remove the cardings in sheet form-from the cylinder 2 as the latter rotates in the chrecti'on of the'arro-w and deliver them to thegathermg and transferring device which will nowbe described.

As-best shown-in'F1gs.:3 and 5 each frameof the carding machine provides a bracket which extendsall the way'ac'rossthe front ro'risupportingthe end portions 8 of a beam' vides a'number of slots 9 and 10 at different levels in which are received bearings 11 for supporting parallel shafts 12 and 13 in different horizontal planes. The shafts 12 and 13 carry rolls 14 and 15 respectively, and

der 2 will. slide down the shield 17 and fall on' the aprons .16. The lower shaft 13 of each apron 16 carries a sprocket wheel 13 around which passes a chain 18 adapted to be driven from a sprocket 19 on a shaft 20 located below the shaft 13. The shaft 20 is journalled in a bearing supported by the beam 8. and is connected by bevelled gearing 21 to a shaft 22 supported in front of the aprons 16 by brackets 23. The shaft 22 extends laterally in front of the member Sand is adapted to be rotatably driven by gearing. 24 from a countershaft 25. The shaft 25 is driven from a source of power, preferably derived from the carding machine, by means of a pulley 26, and it is obvious from Fig. 4, that when the shaft 22 is" so driven, the upper surfaces of the aprons 16 will move toward each other, as indicated by the arrows.

The shaft 22 also carries a roll 27 between the brackets 23,: and as best shown in Fig. 5, the roll 27 carries a belt 28 which extends rearwardly underneath the aprons 16, where it passes around a roll 29. "The. roll 29 is supported by extensions 30 of the brackets 23, and an idler roll 31 is also supported by the bracket extensions 30 with its periphery spaced fromthe belt 28 as it passes over the roll 29 back to the front roll 27. The rolls 29 and 31 are driven in unison and at the same speed as the roll 27 by means of a chain 32, see Fig. 2, passing around sprocket wheels 33 mounted on the shaft 22 and on the roll shaft 29., respectively. The roll shaft 31* also car ries a sprocket wheel 34, the lower periphery of which isengaged by the chain 32,50 that the roll 31 will be driven: in a direction of rotation oppositeto that of the roll 29.

From a consideration of Figs. 1 and 6, it

is evident that when the carding machine is operating to drive the shaft 22, the sheet of cardings from thedofl'er cylinder 2 will be removed by the vibrating knife 6; and will fall upon the oppositely moving surfaces of the aprons 16. The movement ofthe aprons 16 will tend to gather the cardings in the space at B between the ends of the aprons 16,

fromwhence the gathered cardings will pass downwardly between the oppositely moving rolls 29 and 31. As this occurs the cardings will be transformed from an arrangement in sheet form into a continuous web, the width of which is determined by the distance between the aprons 16 at Band the thickness of which is determined by the space between the rolls 29 and 31, or between the belt 28 and roll 31. The fact that the rolls 29 and 31 are positively driven in opposite directions, as

indicated by the arrows, insures that the web will be delivered easily to the apron 28 which will in turn convey it to the front roll 27, which is turning in the same direction of rotation as the rear roll 29. 7

As indicated in Fig. 5, the belt 28 is very loose, the underside of the belt being supported substantially tangentially to the rolls 27 and 29 by means of a guard 35.v By thus supporting the lower side of the belt 28 the upper surface thereof is relatively slack, so that the web is not closely pressed against the underside of the roll 31. In other. words, the belt 28 "is not necessarily driven at the same speed as the rolls 27 and 29, and in cases where very long staple is being handled the belt 28 may be even omitted. In this latter event. theguard 35 prevents the web from saggingtoo much as it passes from the roll 29 to the roll 27. -The web is held to the upper surface of the roll 27 or belt 28 by means of a roll 36 supported between upwardly extending arms 37 of the brackets 23. An apron 38 passes around the roll 36.

and extends upwardly around a ro1l39 supported by a bracket 40 extending from a. ver-.

tical post 41 carried by the beam 8. A second apron 42 extends parallel to the apron 38 and is supported at its top and bottom by rolls 43 and 44 respectively, while a third apron 45, supported on rolls 46 and 47, extends substaitially at right angles to the aprons 38 an 42.

One end of the shaft 22 carries a pulley 48 which is connected by a belt to a correspond- .ing pulley 49 on, the shaft 50 of the roll 46.

Consequently the apron 45 is driven in the same direct-ion as the apron. 38, that is, away from the carding machine, while the aprons 38 and 42 are driven in opposite directions from the shaft 50 to cause their opposed surfaces to move upwardly and confine the web therebetween. 1

The apron 45 is adapted to deliver the web to the receiving table 51' ofa second carding inachine, the Web being distributed laterally on the table 51 by means of a reciprocating head 52 operated by mechanism which forms no port of the present invention above mentioned Patent No. 1,610,209.

From a consideration of Fig. 1, which inbut is fully shownand described in my dicates diagrammaticall the entire course of the carded material, it -1S obvious that when 3 my apparatus is in operation the cardings "are gathered into a fiat web by the operation of the aprons 16 in conjunction with the rolls 29 and 31, the web being formed without substantial alteration of the parallel relation of the fibres of the ca-rdings.

forward and upwardly without any of the twisting which has characterized the transfer of cardings in previous machines, this result being accomplished by the arrangement of all the conveying rolls on parallel axes. Furthermore, the fact that the web is at sub stantially the center of the doffer cylinder 2 permits the web to be conveyed to a point substantially above the center of the feeding table of the second machine without changing direction, in other words, in the shortest possible line of movement.

As previously pointed out, the width of the web is determined by the width of the space B between the aprons 16, and in order to adjust this width, means are provided for shifting the pairs of rolls 1% and 15. To this end each bearing 11 is adjustable in its slot 9 or 10 by means of a. stud 53 threaded into a lug 54 provided on the beam 8. By turning a stud 53 the entire bearing and shaft may be shifted laterally within the slot 9 or 10, so that the space B between the aprons 16 can be very accurately adjusted to control the width of the web being formed.
