Definitions

  • a row of side-by-side primary drafting units are arranged to deliver respective textile webs of different types of fibers to a common conveyor means where they are superimposed and directed to a common processing machine or secondary drafting unit, and wherein all the drafting units and the conveyor means are driven by a common prime mover, with means interconnecting the primary drafting units and the prime mover in such a manner as to permit correlating the speed of delivery rolls of different primary drafting units relative to each other to obtain substantially the same rate of delivery of the webs therefrom to compensate for inherent differences in the delivery rate of different types of fibers.
  • This invention relates to the art of blending masses of textile fibers by drafting the same wherein the masses may differ from one another by having fibers of different lengths and/or kinds or, in the case of cotton fibers, they may come from different bales or from different areas of the world.

  • Many drafting units which may be termed as cushion roll type drafting units, are equipped with a smooth-faced or cushion top delivery roll and a fluted bottom delivery roll.
  • At least the No. 2 top roll; i.e., the top roll immediately rearward of the delivery rolls, of a cushion roll type drafting unit is also a cushion roll resting upon a fluted roll, and the remaining top rolls preferably are metallic, but may be either metallic or cushion type rolls.

Fibers from the primary drafting units are directed to a common processing machine or secondary drafting unit V.
  • each primary drafting unit may be self-contained to the extent that (a) each unit may draft a different type of fibrous material than the others, (b) each unit may impart a different amount of draft to the fibrous material than the others, and (c) the weight per unit length of the material being received by and delivered from each primary drafting unit may be different from that of the other primary drafting units.
  • each primary drafting unit I-IV in the form of a plurality of slivers S, such as card slivers, drawn from a suitable creel including supply cans C.
  • Primary drafting units I-IV deliver the textile material, in the form of respective thin, veil-like, broad, flat, fibrous primary webs W1, W2, W3, W4 onto respective curled guide plates 11 which curve downwardly and beneath themselves to invert the respective webs and change their direction of movement by about 90 as they are deposited upon a supporting means in the form of a primary endless belt conveyor 12.
  • Endless belt conveyor 12 is driven, in a manner to be later described, to direct the webs W1-W4 along the row of primary drafting units and to direct the composite web W5 onto the upper run of a secondary belt conveyor 14 which extends upwardly and forwardly at an angle to direct the composite web W5 into secondary drafting unit V.
  • a calendering and crimping device 15 is provided above primary conveyor 12 and adjacent the discharge end of each curved plate 11 to aid in preserving the relationship of the fibers in each respective primary web W1-W4 while effectively pulling and advancing the respective primary web toward conveyor 12. Additionally, following the crimping and subsequent superimposing of the primary webs Wl-W4, and before the resultant composite web W5 enters the secondary drafting unit V, the composite web is compacted by means of a secondary calendering device 16.
  • the secondary drafting unit V is arranged to blend and draft the composite web and deliver the same in the form of a web which may be taken up on a suitable roll, not shown, or which may be condensed into a blended sliver S (FIGURE 3A) and coiled into a can 20 for further processing.
  • Each drafting unit IV may comprise a plurality of sets of top and bottom drafting rolls, there being four sets of such rolls provided for each drafting unit in this instance, indicated at 31-34 and 31'34', respectively.
  • Rolls 31-34 are generally known as No. 4, No. 3, No. 2 and No. 1 top rolls, respectively.
  • the drafting rolls of all drafting units I-V may be arranged as shown in FIG- URES 4, 5 and 6, wherein portions of drafting unit IV are shown.
  • the blending system is capable of accommodating either or both metallic roll type and cushion roll" type drafting units.
  • the drafting units I-V may be of either or both types and, as shown in FIGURES 3 and 3A, for example, primary drafting units I, II and secondary unit V are each of the metallic roll type in which all the top rolls 31-34 are fluted and mesh with the respective bottom fluted rolls.
  • primary units III, IV are shown as being of the cushion roll type in which all the top rolls may be of the cushion type or, as shown and is more generally the case, in which the delivery or No. 1 top roll 34 and the No. 2 top roll 33 are of the cushion type resting upon fluted bottom rolls; and the No. 3 and No. 4 top rolls 32, 31, respectively, are fluted metallic rolls meshing with the respective fluted bottom rolls 32', 31' (see FIGURE 5).
  • a metallic roll type drafting unit is desirable for drafting and producing standard weight and heavy weight fibrous material of from 50 to 600 grains per yard or heavier whose fibers are of standard or greater coarseness (8 denier and more) because, even though the pressure applied to fluted top rolls may be as little as 16 pounds (which is about 5 percent of the pressure applied to cushion top rolls), the intermeshing flutes of metallic rolls, due to the bulk of the mass, grip such material very firmly so there is very little if any slippage of fibers between a pair of intermeshing fluted rolls.
  • Metallic No. 3 and No. 4 top and bottom rolls are desirable in a cushion roll drafting unit because of the greater weight of the stock, the relatively small amount of draft being imparted thereto, and the relatively slow linear speed of the stock passing through these particular rolls as compared to the stock passing through the front drafting zone and between the delivery or No. 1 and the No. 2 drafting rolls.
  • the earlierdescribed advantages of metallic roll drafting are applicable in the rear drafting zones of a cushion roll drafting unit.
  • each primary drafting unit I-IV is arranged for independent operation to the extent that the fibers being drafted by each primary drafting unit may differ in one or more respects relative to the fibers being drafted by another or other primary drafting units.
  • the delivery speed of separately drafted different kinds of fibers varied from about 100 f.p.m. (feet per minute) to about 110 f.p.m.

  • a web formed only of Dacron fibers (polyester staple) issued from delivery rolls at about 104 f.p.m.
  • a web formed only of cotton fibers issued from delivery rolls at about 110 f.p.m.
  • Further variation in delivery speed of the webs has also been experienced in changing from one denier and/ or staple length to another.
  • reference to various types of fibers shall mean that the fibers in one or more masses differ from those fibers in another or other masses with regard to average staple length, relative slipperiness of adjacent fibers, and/ or slippage of the fibers relative to the corresponding drafting rolls, such that the roll spacing, the amount of draft effected in the drafting zone between adjacent sets of drafting rolls, and/or the speed of the delivery rolls 34, 34' required to effect a given delivery speed of the web at any one or more of the primary drafting units I-IV must differ with respect to another or others of the primary drafting units.
  • each roll stand 40 may be provided with a longitudinal slot 43 in its upper bridging portion through which a screw 44 for each bearing block 37 extends for securing the bearing blocks in the desired adjusted positions in accordance with the staple length of the fibers in the particular mass being drafted by the particulardrafting unit.
  • a common jack shaft 50 extends along the row of primary drafting units I-IV and is drivingly connected to the front drafting rolls of each primary drafting unit by an individual transmission means or gear train including a drive gear 51 fixed on shaft 50 and meshing with one of a pair of change gears 53 (FIGURE 6).
  • the other of the change gears 53 engages a gear 54 fixed on one reduced end of the corresponding bottom delivery drafting roll 34'.
  • the change gears 53 provide means for adjustably controlling the speed of each pair of delivery rolls 34, 34' independently of the other pairs of delivery rolls, as well as adjustably controlling the speed of all the rolls of each respective primary drafting unit, even though all the primary drafting units are driven by jack shaft 50.
  • the change gears 53 associated with each primary drafting unit are fixedly interconnected in axial relationship and are mounted on a stub shaft 58 adjustably secured to a pivoted bracket 59 whose lower portion is pivotally supported on jack shaft 50.
  • Each pivoted bracket 59 is provided with an arcuate slot 60 therein (FIGURE 7) penetrated by an adjustment screw 61 for adjustably securing the same to a standard 62.
  • Each standard 62 is fixed upon the frame 41 of the corresponding primary drafting unit.
  • Jack shaft 50 is journaled in standards 62 and may extend through the roll stands 40 of primary drafting units I-IV so that it may be positioned beneath and adjacent bottom delivery rolls 34', as is preferred. If so desired, jack shaft 50 may be manufactured in short sections with suitable couplings 64 (FIGURES 3 and 3A) interconnecting adjacent sections thereof at the junctures of adjacent primary drafting units.
  • the end of jack shaft 50 adjacent secondary drafting unit V is connected to the output side of a gear box 66 whose input side has a sprocket wheel 67 fixed thereon engaged by an endless sprocket chain 70.
  • Sprocket chain 70 is also mounted on a sprocket wheel 71 fixed on a shaft 72 connected by a train of gears 73 to the drafting rolls of secondary drafting unit V.
  • the drafting rolls of secondary drafting unit V are interconnected, in a conventional manner, by the usual draft gearing and the front bottom drafting roll 34 of secondary drafting unit V is connected to electric motor or prime mover 10, preferably by means of an electromagnetic clutch 76 which may be energized and deenergized in a well-known manner for starting and stopping secondary drafting unit V and thus for starting and stopping the entire drafting and blending system of the present invention.
  • each gear 54 is connected to one of the intermediate drafting rolls through a gear train including change gears 80, and the other end of the latter intermediate bottom drafting roll is connected by a gear train 81 to the other intermediate bottom drafting roll and to the bottom feed roll 31' of the corresponding drafting unit.
  • Any suitable means may be employed for applying yieldable downward pressure to each end of each top drafting roll 31-34, such as is shown in United States Patents Nos. 2,412,357 and 3,143,772, for example.
  • Such pressure-applying means may include a separate springloaded plunger 90 bearing against each bearing 36.
  • the spring-loaded plungers at each side of each drafting unit may be carried by supports 91 overlying the corresponding bearings 36.
  • conveyor pulley 101 is connected to one of the output sides of gear box 66 by means of a pair of sprocket wheels 110, 111 and an interconnecting endless sprocket chain 112, thus operatively connecting the conveyors 12, '14 to prime mover 10.
  • suitable support plates or platforms 115, 116 may be provided therefor.
  • Platform may be supported by cantilever arms 117 secured to and projecting outwardly from the frames of adjacent primary drafting unils.
  • Platform 116 may be similarly supported by the frame of secondary drafting unit V.
  • the primary calendering devices 15 are provided to ensure the desired degree of adjustment of the rate of travel of the primary webs W1- W4, under the desired tension, from the respective primary drafting units to the belt conveyor 12, especially when cushion-type top delivery drafting rolls are used.
  • the gears 5254 (FIGURE 6) should be relatively small.
  • the range of change gears, such as gears 53, which may be used does not always permit the fine adjustment of tension draft needed for best results.
  • each primary calendering device comprises a pair of top and bottom fluted intermeshing calendering rolls 120, 121 which may be of the same type as illustrated feed rolls 31, 31' of each drafting unit.
  • each curved plate 11 terminates closely adjacent the nip of the respective pair of primary calender rolls 120, 121, and, additionally, the calender rolls 120, 121 are arranged in angular positions; i.e., an imaginary line extending through and perpendicular to the axes of the calender rolls 120, 121 extends at an acute angle with respect to the forward direction of movement of the upper run of belt conveyor 12.
  • Bearing stands 123 may be suitably secured to corresponding cantilever arms 117 heretofore described (FIG- URES 3, 3A, 4 and 5).
  • the bottom calender rolls 121 of the primary calendering devices 15 are drivingly connected to a calender drive shaft by suitable gearing, not shown, in respective gear boxes 131 suitably secured to the respective cantilever arms 117.
  • Calender drive shaft 130 is common to all the primary calendering units 15, is rotatably supported in gear boxes 131, and is driven by suitable driving connections with jack shaft 50, such as are shown in FIGURE 2. Accordingly, the end of shaft 130 adjacent the first primary drafting unit I has a gear 133 fixed thereon which meshes with an idler gear 134 suitably supported by the frame of drafting unit I and fixed in a axial relation to a pulley 135.
  • Pulley 135 is engaged by an endless belt 136 which also engages a pulley 137 fixed on the corresponding end of jack shaft 50. It is thus seen that prime mover 10 is drivingly connected to the bottom rolls 121 of the primary calcndering devices 15.
  • Prime mover 10 is also drivingly connected to a pair of smooth-faced calender rolls 140 of secondary calendering device 16 by means of a pair of sprocket wheels 141, 142 and an interconnecting endless sprocket chain 143.
  • Sprocket wheel 141 is fixed on one reduced end of the bottommost of the smooth-faced calender rolls 140, and sprocket wheel 142 is arranged in fixed axial relation to sprocket wheel 111.
  • the calender rolls 140 of secondary calendering device 16 may be mounted in the same manner as rolls 120, 121 of the primary calendering devices 15 and, therefore, a further description of the calendering device 16 is deemed unnecessary.
  • any drafted fiber web is thicker longitudinally of its central portion than it is at its outer edges. This results in the web gradually increasing in width when it is being pulled from delivery rolls 34, 34 between the primary calender rolls 120, 121 (FIGURE 4) and while the webs are being advanced by the conveyor means 12, 14.
  • synthetic fibers have slicker or smoother and more slippery surfaces than natural fibers, such as cotton fibers, synthetic fiber webs spread laterally when being pulled, to a greater extent than cotton webs.
  • the slivers S may be so arranged upon entering the respective primary drafting units I-1V that any synthetic fiber web or webs emerging therefrom are compensatively narrower than any cotton web or webs emerging therefrom so that, by the time that the composite web W formed therefrom reaches the secondary drafting unit V, the synthetic fiber web or webs will have increased in width to a greater extent that the natural fiber web or webs so that all the webs of the composite web W5 will be of substantially the same width, thus further contributing to uniformity of the blend.
  • each primary drafting unit (1) is capable of drafting textile fibers of a different type (different kind and/or average staple length) than that of the fibers being drafted by the other primary drafting units, (2) is capable of applying a different amount of draft to corresponding fibers than that applied by the other primary drafting units, and (3) may deliver the corresponding primary web therefrom at substantially the same speed as that at which the primary webs are delivered from the other primary drafting units and in accordance with the speed at which the webs are to be drawn into the secondary unit V.
  • the change gears 53 provide means for adjusting the speed of each pair of delivery rolls so the delivery speed of all the primary webs may be substantially the same, thus providing a basis for determining the rate of travel of each primary web in its course to belt conveyor 12. Such changes in the speed of the delivery rolls are automatically reflected in the speed of all the rolls of the respective primary drafting units without changing change gears 80.
  • the primary calender rolls 120, 121 serve the function of imparting added crimp to each primary web when fluted delivery rolls are used or impart initial crimp when composition top delivery rolls are used at the drafting units LIV. More importantly, the primary calender rolls 120, 121 provide means for facilitating proper tension draft for each one of the different types of webs emerging from the primary drafting units, while providing for the proper rate of feed of each one of the webs onto primary conveyor 12. The latter function of fluted calender rolls 120, 121 may be appreciated by comparison of the action of the fluted calender rolls upon two different types of webs; namely, a synthetic web and a cotton web, both of the same weight and emerging at about the same linear speed from delivery rolls 34, 34 of different primary drafting units.
  • the rolls 120, 121 for the synthetic web would have to be in deeper intermeshing relationship than the fluted calender rolls for the cotton web so as to advance the synthetic web faster than the cotton web.
  • the crimping effect of the fluted calender rolls causes both types of webs to emerge from the respective pairs of calender rolls in somewhat corrugated or undulated form, and the linear speed of the upper reach of conveyor 12 is such as to impart a small amount of tension to the webs as they are deposited and/or superimposed thereon.
  • Elasticity is imparted to the primary webs by virtue of the crimp imparted thereto by the fluted calender rolls 120, 121.
  • the pull of the conveyor acting on the corrugated synthetic and cotton webs removes only a relatively small amount of the undulations or crimp from the faster moving synthetic web as compared to the amount removed from the slower moving cotton web to avoid excessive accumulation or pile-up of the faster moving web on conveyor 12 and to ensure proper successive superimposing or stacking of the different types of webs on conveyor 12.
  • the delivery speed of the synthetic web at corresponding delivery rolls 34, 34' may be reduced by use of appropriate gears 53. or preferablv bv increasing the draft of the corresponding rimary drafting unit, so the weight of the synthetic web approaching corresponding calender rolls 120, 121 will have been reduced compensatively.
  • a secondary sliver S weighing 60 grains per yard having 20% 20% combed cotton fibers of about one one-eighth inch combed cotton fibers of about one and one-eighth inch average staple length, 30% Orlon fibers of about one and nine-sixteenths inches average staple length, and 40% Acrilan fibers having three inches average staple length therein.
  • the slivers S fed into the primary units each weigh 60 grains per yard, with all the slivers S except the combed cotton slivers being card slivers.
  • thirteen ends of card slivers of Acrilan fibers having three inches average staple length may be directed from separate cans C into metallic roll primary drafting unit I; ten ends of Orlon fibers having an average staple length of two inches may be directed from separate cans into metallic roll primary drafting unit II; five ends of Dacron fibers having two inches average staple length may be directed into cushion roll primary drafting unit III; and eight ends of combed cotton fibers having one and one-eighth inches average staple length may be directed into cushion roll primary drafting unit IV.
  • the total draft imparted to the fibers at the primary drafting units I-V would be 4.07; 4.16; 6.25 and 5, respectively.
  • the primary webs Wl-W4 is suing from the drafting units I-IV would weigh about 192, 144, 48 and 96 grains per yard, respectively, and the composite web W5 formed thereform thus would weigh about 480 grains per yard.
  • the 480 grain-per yard composite web W5 would then be subjected to a draft of 8 as it is passed through secondary drafting unit V to form the blended sliver S weighing 60 grains per yard.
  • primary units I, II of this example are of the metallic roll type, as is desirable in producing the heavier webs of synthetic fibers.
  • primary units II, III of this example are of the cushion roll type, as is desirable in producing the very light (48 grains per yard) Dacron web and the highly parallelized combed cotton web.
  • the delivery speed of and amount of draft imparted to the fibers by the secondary drafting unit V are substantially greater than that of each primary drafting unit.
  • the secondary unit preferably is of the metallic roll type.
  • the primary webs Wl-W4 are compacted and crimped individually by the fluted calender rolls 120, 121 associated with the primary drafting units to lend tensile strength thereto to assist in preventing rupture of the thin primary webs as they are superimposed, and to effect an efficient transition of the webs to the conveyor means.
  • a further compacting of the webs occurs at the secondary calendering device 16 which not only lends tensile strength to composite web W5, but also intermixes the fibers of adjacent superimposed webs in the composite web W5, thus further assisting in the homogenous distribution of the various types of fibers throughout the blend.
