in fig1 a textile processing system is illustrated at 10 as including , proceeding right to left , a chute feed 12 , supported upon a pedestal or base 14 , a card 16 and a coiler 18 ( for instance a dual coiler , of which only the near - side coiler unit is visible in this view , the far - side coiler being identical to it and obscured by it in this view ). all of these may be generally conventional or well - known , commercially available items of equipment . for example , the chute feed may be a model ml - 5 chute feed manufactured by fiber controls corporation , of gastonia , n . c . 28052 , and the card / coiler arrangement may be a hollingsworth americard dual coiler . an exempliary adjustment feature provided in accordance with the principles of the present invention is shown illustrated generally at 20 in fig1 and on a larger scale in fig2 . the system 10 is shown schematically in fig3 . the ideal spatial relationship of the card 16 to the chute feed 12 is the one which causes the output of the card to have minimized side - to - side variation , so that as divided and furnished to the coilers , should there be two as shown , the left side and right side products as are indistinguishable from one another as possible , and each is a consistent product . nominally , the ideal spatial relationship is the one wherein the longitudinal center line 22 of the card 16 is co - planar with the longitudinal center line 24 of the chute feed 12 . however , the present inventor has found that an adjustment feature is needed in order to achieve the actual ideal spatial relationship , whether the effect of adjustment is to produce or to cause more or less variation from the co - planarity just referred to . in a preferred embodiment , the adjustment feature 20 is physically located so as to act between the chute feed 12 and whatever it is that the chute feed is supported upon in order to pivot , swivel , skew , turn or similarly to move the chute feed slightly in a generally angular sense about a generally vertical axis without causing any significant lateral translation of the chute feed , i . e . such as would disturb connections of fiber feed ducting to the chute feed , or of drive connections extending between the chute feed and the card . as illustrated in fig3 an exemplary way that this can be accomplished is to provide the adjustment feature 20 at one lateral end of the chute feed , which , upon adjustment moves that end of the chute feed towards and away from the card along an arc generally indicated by the double - headed arrow 26 . the axis of this arcuate movement in this instance may be located in the vicinity of the opposite lateral end of the chute feed , e . g . at 28 . however , if considered necessary or desirable a similar adjustment feature may be provided at 28 , so that when only the adjustment feature at 20 is adjusted , pivotal movement is about an axis at 28 , and when only the adjustment feature at 28 is adjusted , pivotal movement is about an axis at 20 , whereas if both are adjusted , e . g . to lengthen one and shorten the other , the effective axis of the pivotal movement lies somewhere between the two lateral ends of the chute feed . as indicated , each adjustment feature , e . g . the adjustment feature 20 is mounted to act between the chute feed and whatever it is that the chute feed is supported - upon . in the embodiment shown in fig1 and 2 , the chute feed 12 is supported upon a stationary pedestal , stand or base 14 and it is between these two members that the adjustment feature 20 is mounted to act in the illustrated embodiment . however , because as hereinbefore stated the chute feed in utterly equivalent instances may rest directly on the floor , or upon the card , the adjustment feature in those instances would be mounted to act between the chute feed and the floor , and between the chute feed and the card , respectively . now , to describe the illustrated preferred embodiment of the adjustment feature 20 in more detail , reference will be made to fig2 . in fig2 one is looking at structure located adjacent the near side of the system 10 . the horizontal bottom wall of the chute feed 12 is illustrated at 30 and the horizontal top wall of the chute feed support stand 14 is illustrated at 32 . the chute feed 12 is seen to forwardly overhang the stand 14 so as to be desirably adjacent the card 16 . the vertical front wall of the stand 14 is indicated at 34 . an l - shaped angle bracket 36 is shown secured by a nut and bolt assembly 38 to the underside of the bottom wall 30 of the chute feed , forwardly of the stand 14 . the bracket 36 is disposed in an inverted condition , so that its horizontal flange 40 is uppermost . this flange is provided with a slot 42 vertically therethrough , which slot is elongated transversally of the system 10 . the nut and bolt assembly 38 is fastened through this slot 42 and through a hole 44 provided in the bottom wall 30 of the chute feed . the vertical flange 46 of the angle bracket 36 , which is shown extending transversally at the rear is provided with a horizontal opening 48 through the thickness of the flange . on line with the opening 48 , a horizontal opening 50 is formed through the front wall 34 of the stand 14 . a threaded rod 52 , e . g . five inches long is shown received through the aligned openings 48 and 50 , its disposition being adjustably fixed by respective nut / lock nut pairs 54 and 56 . in each instance a washer 58 is shown intervened between the respective nut or lock nut and what it bears against . in order to move the near end of the feed chute rearwardly away from the card ( i . e . relatively to the right in fig2 ), the lock nut of the pair 54 may be loosened a few turns and the nut of that pair tightened a few turns until the connection is tight again . this pulls the flange 46 towards the wall 34 , just jacking the near end of the feed chute 12 backwards ( i . e . to the right ) on the stand 14 , with the far end of the feed chute 12 ( not shown in this view ), remaining where it was . the slot 42 accommodates the slight arc to this movement . similarly , if nut and bolt assemblies or the like are provided vertically between the top of the stand and the bottom of the feed chute , e . g . as illustrated at 59 , one or the other or both of the respective openings may be slotted , e . g . as illustrated at 60 to accommodate the necessary movement . like the nut and bolt assembly 38 , the nut and bolt assembly or assemblies 58 are normally kept tight but are slightly loosened when an adjustment is to be made of the chute feed , and after the adjustment is made , these nut and bolt assemblies may be retightened to the extent considered necessary . the near end of the chute feed is moved towards the card , i . e . towards the left in fig2 by a comparable manipulation of the elements just described . in order to permit the principles and operation of the preferred embodiment and the invention to be even better understood , a practical example is now given . using the system of fig1 - 3 , in which the chute feed 12 was a fiber controls ml - 5 chute feed ( thirty - six inch wide output ) and the card / coiler was a hollingsworth americard ii dual coiler ( forty inch wide card capacity ) having a right side coiler and a left side coiler , a series of tests were run using as a test fiber 431 fortrel polyester 1 . 5 × 1 . 5 at a card production rate of 120 pounds per hour . for the first test run , the chute feed was nominally aligned with the card . the sliver obtained by the right side collar was compared with that obtained by the left side coiler for uniformity of weight per standard unit length ( grains per ten yards ) to obain the highest and lowest values , and , for each side , the coefficient of variation ( cv ), using the industry - standard uster method . from the first test run , the following results were obtained : ______________________________________ right side coiler left side coiler______________________________________highest 55 . 8 59 . 8lowest 55 . 0 59 . 4uster cv 4 . 3 % 5 . 4 % ______________________________________ the results of the first test run are interpreted as indicating that too much fiber is being fed to the left . accordingly , for the second test run , the left side of the chute feed was moved about one - sixteenth inch closer to the card by respective manipulation of the adjustment feature 20 , and the following results were obtained : ______________________________________ right side coiler left side coiler______________________________________highest 56 . 6 57 . 1lowest 55 . 4 58 . 6uster cv 4 . 4 % 5 . 4 % ______________________________________ the results of the second test run indicate that some improvement in side - to - side card output uniformity has been achieved by the adjustment although the coefficient of variability on each side desirably would be lower . for the third test run , two changes were made . first , the left side of the chute feed was brought another sixteenth of an inch closer to the card by corresponding manipulation of the adjustment feature 20 , seeking to further even out the weight difference between coilers and to lower the coefficients of variability . second , in order to eliminate batt fast drafting due to cock , the sprocket on the card feed roll conventionally used with an endless chain for driving the card feed roll from the feed roll of the feed chute was changed from a fourteen tooth sprocket to a fifteen tooth sprocket , thus reducing draft by slightly reducing the rate at which the card feed roll was driven . then , from the third test run , the following results were obtained : ______________________________________ right side coiler left side coiler______________________________________highest 56 . 8 57 . 9lowest 56 . 7 57 . 2uster cv 3 . 4 % 3 . 6 % ______________________________________ the target weight being 57 grains , and these coefficients of variability being acceptably low , the system 10 is considered from the results of the third test run to be properly adjusted for continued use . it should now be apparent that the chute feed adjustment for card evenness as described hereinabove , possesses each of the attributes set forth in the specification under the heading &# 34 ; summary of the invention &# 34 ; hereinbefore . because it can be modified to some extent without departing from the principles thereof as they have been outlined and explained in this specification , the present invention should be understood as encompassing all such modifications as are within the spirit and scope of the following claims .
