  • Step I In order to reduce down time and increase productivity in succeeding steps and thus effect considerable savings, each yarn of a web thereof is first stressed in a testing apparatus, shown schematically in FIG. 3, by passing it around a weighted floating or movable roller which momentarily applies sufficient tension to the yarn to break it if a place occurs in the yarn which does not have a desired tensile strength.
  • the testing device When an end of yarn breaks, the testing device is automatically stopped by control means such as a drop wire mechanism.
  • a yarn which does not break then passes around a second floating roller of lower weight in order to reduce the yarn tension to a desirable level for succeeding steps.
  • Step 2 From the testing station, the yarn ends may be fed directly to a printing apparatus indicated generally by numeral 6 or may preferably be taken up on one or more warp beams indicated generally by numeral 4, before succeeding steps. If taken up on warp beams, then later, yarns from the desired beam 4 are led into the printing apparatus 6. If this practice is followed, the following method is used to reduce beam changing time.
  • Each beam station feeding into the printing apparatus accommodates two beams positioned with their axes parallel. Yarn from one of the beams of each pair is first used, and when the particular beam is empty, the yarn from the second beam is immediately tied in. The empty beam is then removed, and a filled spare beam is put in its place. This alternating use of the beams eliminates most of the down time caused by changing beams when beams run out of yarn.
  • the beams are also arranged so that as many are in use are simultaneously accessible for tieing or splicing yarn during beam changes.
  • Step 3 Next the yarn is moved from the beam let-off and through suitable guides by means of a driven infeed drum 5 of sufficient diameter and friction to deliver yarns at a constant and equal rate of travel to a floating or dancer roller 7.
  • This roller is of appropriate weight for delivering yarn at consistent tension desired to the printing apparatus 6. This consistent tension is necessary for consistent dye pick up.
  • the floating roll also actuates switches which start and stop the infeed drum.
  • Step 4 A suitable dye liquor or low viscosity paste is then applied by apparatus 6 to the yarn. This is done in a series of roller stations within the apparatus by pressing the yarn by means of a movable top roller against a bottom felt covered roller which is partially immersed in a trough containing the dye material, and which is driven at approximately the same surface speed as the yarn. While only one set of top and bottom rollers may be used, the use of a plurality of sets is preferred (as shown) for greater facility and speed of coloring the yarn in preselected patterns and colors.
  • the dye material level in the trough is maintained by a liquid level control system.
  • the amount of dye material in the cover material of the bottom roller when it contacts the yarn, is determined by a weighted doctor roller that rides against the bottom roller.
  • the duration of contact between the yarn and the covered roller is controlled by a mechanical programmer that actuates switches which in turn actuate air valves.
  • the latter supply air to air cylinders at the ends of the pistons of which are mounted the bearings for the top rollers. Actuation of the air valves for each set of rollers causes the top roller to move downwardly and press all of the yarn ends passing through the particular set of print rollers down against the dye-laden covered bottom roller for a predetermined length of time.
  • a plane containing the axes of the bottom and top rollers of a given set is related to the direction of the path of the sheet between the rollers so that the sheet makes an angle with respect to the plane of
  • the puddle of dye paste formed behind the nip of the rollers while the rollers are in contact and printing the yarn ends will fall away from the yarn ends when the top roller is lifted by the force of gravity, as well as the capillary action of the bottom roller cover.
  • the yarn path is controlled by yarn guides (not shown) on either side of the print rollers.
  • the length of stroke of the air cylinder pistons. the overall length of the air cylinders and the air pressure in both ends of the cylinder at all times are controlled to insure clean sharp points.
  • the mechanical controller is best described as a plurality of discs having holes in their perimeters in which may be inserted rubber flat-topped pegs.
  • the holes are so spaced that the tops touch and thus form a switch operating cam surface of a pre-set length.
  • the length is adjusted by changing the number of adjacent pegs.
  • a further feature is the use of an electric brake/- clutch to disengage the programmer and hold its position while yarn is jogged through the printer. This is done to correct for wet yarn length growth which occurs during printing, if the passage of yarn through the printer should be stopped for a period of time. if not corrected, the yarn growth results in the prints made on start-up to be out of sequence and causes errors in the final fabric.
  • a plurality of finned rollers pull the yarn through the printer.
  • Each of these rollers has four fins attached longitudinally to the roller along the length thereof and extending radially outwardly.
  • the fins are necessary for reducing surface contact of the wet printed yarn with the roller surface. If a plain roller is used, an excessive amount of dye paste is transferred to the roller and redeposited on yarn. This causes an unwanted second printing.
  • the fins also reduce the amount of cohesion between the wet yarn and the roller permitting easier release from the latter. Also, if a yarn end does not release from the roller, it will wrap around the latter and cause a shut down. After the yarn has passed through the finned rollers.
  • the web or sheet width of the yarns leading into and out of the printer 6 is controlled by guide bars or reeds which have as many holes as there are yarns to be processed.
  • the spacing between the holes determines the length of the guide bar and the width of the web.
  • the web is made narrow during printing so as to minimize side to side printing variations, and is made wide for dye fixation, washing and drying so as to increase surface exposure of the yarn to these subsequent operations.
  • Step 5 The yarn is then passed into the dye setting or fixation chamber indicated generally by numeral 8.
  • a horizontal conveyor belt 116 which is of open mesh construction to permit air or steam to pass easily through it, has its upper reach enclosed by the steam chamber 8.
  • This chamber has means for admitting live steam beneath the upper reach of the belt and means for heating the roof of the chamber, which is over the upper reach.
  • the heated roof prevents steam condensation and makes possible a temperature in the chamber of 2l0 to 230F.
  • An air lock 198 is provided at both ends of the steam chamber. The air locks are fitted with suitable exhaust means which are used to purge air from the steam chamber, carry off excess steam from the chamber, and also cool the yarn before it exits from the steam chamber.
  • the yarn ends are deposited on the conveyor belt at the inlet end of the steam chamber and pass thru the latter in a relaxed state. Live steam passes upward through the conveyor belt and through the yarns while heat is radiated downward thereon from the chamber roof.
  • Step 6 The yarn progresses to the exit end of chamber 8, and does not leave the conveyor belt until it has passed through the nip of the exit rollers of the belt.
  • the yarn then passes through a washer indicated generally by numeral 10, and which consists of a plurality of vertical adjacent rollers.
  • the odd-numbered rollers are non-porous, fixed and driven; while the even numbered rollers are covered with a porous material. and are free turning and movable toward or away from the fixed rollers. Water is applied along the entire length of the second roller from the top, and since the rollers are vertical the water cascades downward over all of the rollers.
  • the yarn from steam chamber 8 enters the wash roller stack at the bottom and follows a serpentine path around the rollers to the top.
  • the cascading water and the squeezing action in the roller nips effectively wash out any unfixed material from the yarn ends.
  • the uppermost nip since water is supplied below it extracts water from the yarn ends and prepares them for drying.
  • the quantity of water needed with this method and apparatus is reduced greatly since the water is used several times during its path down the rollers.
  • each covered roller is squeezed at two opposite sides rather than one as is normally the case with a series of two roller wringers. This doubles the number of wringings for any given number of wrapped rollers or halves the number of wrapped rollers needed for any given nunmber of wringings.
  • a pan is provided under the stack of rollers to collect the spent water.
  • the yarn then passes to another set of finned rollers and to an inclined chute as described in Step 4, and thence onto a conveyor belt leading into drying chamber indicated generally by numeral 12.
  • Step 7 After leaving the chute in Step 6, the yarn is deposited as plaits on the upper reach of a horizontal open mesh conveyor belt 234 which is enclosed by the hot air chamber.
  • This chamber has means for moving air from under the upper reach of the belt, exhausting part of this air, adding fresh replacement air, heating the air and forcing heated air downwardly from above the top level of the belt, through the yarn and through the upper reach of the belt.
  • Hot air chamber 12 is provided with pairs of nip rollers immediately adjacent the inlet and exit of the chamber, through which pass the belt and the yarn.
  • the entrance pair of nip rollers prevent hot air from blowing out of the chamber and also compact the yarn for more efficient drying.
  • the exit nip rollers of the hot air chamber serve the same function as described in Step 5, that is, the yarn ends are pulled from the conveyor belt only after passing through the exit roller nip.
  • the configuration of the hot air chamber is such that after a thermoplastic yarn is dryed, its temperature may be effectively and uniformly raised to stress relieving or setting temperatures for the particular yarn.
  • the introduction of the hot air into the hot air chamber is done by a plurality of blowers l3, l5, l7 and 19.
  • blowers l3, l and 17 will provide air at a temperature below the heat setting temper ature of the yarn being processed, and blower 19 will provide air which is of high enough temperature to raise the yarn to the setting temperature.
  • this raising of the yarn temperature occurs preferably during approximately the last (prior to exit) quarter of the passage of the yarn through the chamber. It is thus possible to stress relieve or heat set a thermoplastic yarn in the hot air chamber either in conjunction with or separately from the drying operation.
  • Step 8 The yarn then passes from the restraining nip of the exit nip rollers beyond the dryer belt exit and round two or more fixed bars which further restrict movement of the yarn on the belt. Sufficient tension for carrying out Step 8 and the following Step 9 is applied at this point by another weighted floating roller 258. Between the restraining bars and the floating rollers each end of yarn is passed through a separate guide. The guides are spaced so that all the ends of yarn are restored to approximately the same longitudinal and lateral alignment that they were in when printed.
  • Step 9 Each end of yarn then passes through the ad ditional guides of the shuffler" 14 which are so positioned that each end of yarn (or the ends of a group of yarns) is shifted from the lateral position in relation to all other yarns that the yarns had when leaving the printing apparatus 6, to a new lateral position in relation to all other yarns.
  • the new lateral position will eliminate any side to side color variations which may be present in the printed web of yarn, preferably each yarn is shifted to the maximum mathematical position away from the original printed lateral position.
  • Such a shuffler is shown and described in the aforesaid US. Pat. Nos. 3,447,215 and 3,62 l ,780, the teachings of which are incorporated herein by reference.
  • an accumulator 16 which is used to accumulate and store yarn during interruptions in any subsequent steps and thereby permitting preceding steps to continue without interruption.
  • Step I l Each end of yarn then passes through a separate movable guide.
  • Each guide can be moved so that the longitudinal relation of each yarn to all other yarns can be changed. Differences in the lengths of the paths of different ends of yarn causes them to be displaced from the longitudinal alignment existing when the yarns were printed; or, if already displaced, by moving the above movable guides the longitudinal printing alignment can be restored.
  • the movable guides can be either the first set of rollers of accumulator 16, or can be the first set of rollers of the de-aligner 18.
  • the yarn inspection device indicated generally by FIG. 3 is a means for taking yarns from a supply package such as cones 0r beams, and passing them through an apparatus which will test for weakness in the individual yarn ends by applying tension to each yarn end, and thereafter relaxing that tension before the individual ends exit from the inspection device.
  • a supply package 30 is shown, in this case being a cone of yarn, one for each yarn end. From the cone 30, a yarn 32 passes through suitable tension bars 34 and around the fixed roller or bar 36.
  • the yarn then passes around a drum 38 which comprises a cylinder (preferably hollow) approximately I foot in diameter, the surface of the cylinder being covered with a friction material such as waterproof emery cloth 8() l 00 grit, the latter being cemented on the drum in any conventional manner.
  • Drum 38 is supported by its shaft 39 in bearings 41 supported in framework 43 of the apparatus.
  • the yarn thereafter passes (by suitable guide means 40 ofconventional nature) through a drop wire or warp thread shut-down device indicated generally by numeral 42. (Each yarn has such a device).
  • Such devices are conventional, and are used in looms, and consist of, for example, wires or plates having a hole at one end thereof through which the yarn passes. lfa yarn breaks, then the particular wire will drop and actuate a suitable stop mechanism for the drum (Since there will be a plurality of yarns passing around the rolls, there will be a plurality of drop wires.)
  • each yarn 32 passes through its respective drop wire or other breakage indicating device, it is passed around a roller 46 which is mounted in suitable bearings at its ends, and is adapted to move horizontally. Attached to the bearing of the roller by suitable means such as a bridle is a wire 48 passing over pulley 50. A weight 52 is suspended from wire 48.
  • Weight 52 is of such size that a pulling force of 2 to 10 pounds (depending upon the yarn material and yarn size being tested) will be exerted on each yarn end. That is, if there are, for example, 50 yarn ends encircling the horizontally movable tension roller 46, the weight 52 will weigh 100 to 500 pounds, so that each yarn will be pulled with a force of 2 to 10 pounds.
  • roller 54 After the yarn 32 encircles the tension roller 46, it proceeds to roller 54, is trained around the latter and then encircles a drum 56 like drum 38.
  • Drum 56 is also mounted on its own shaft in suitable bearings 41 supported by framework 43.
  • Drum 56 is covered, as is roller 38, with a non-slip covering, such as a water-proof to lOO grit emery cloth.
  • yarn end 32 After partially encircling the roller 56, yarn end 32 is lead downwardly and supports the relatively lightweight dancer roller 58 which is used as a tension relaxing roller as will be explained below.
  • the yarn end passes upwardly and over roller 60 and thence leftward (as viewed in FIGv 3) through a suitable guide 62, the latter being used to laterally align the yarn ends prior to either winding the yarns on a beam 4, or conveying the yarns directly to the printing device.
  • drums 38 and 56 Separate drives and speed controls indicated by numerals 64 and 66 are provided for drums 38 and 56 respectively. Each of the drums, therefore, can have its speed adjusted to be at a different rate than the other one.
  • the purpose of having the drum speeds at least initially variable, is to be able to transport yarn by drum 58 in order to apply the weight 52 to roller 46. Also, to adjust for stretch in the yarn.
  • the dancer roller 58 which is a floating roller enabled to move vertically up and down
  • a tensioning force less than the testing force may be applied to the yarn ends.
  • approximately 0.6 to 0.8 pounds tension force may be applied to the yarn end. This is a constant tension applied to all the yarns for the next step in the sequence, which may be either winding on a beam, or feeding directly to the printing apparatus.
  • the drive and speed controls 64, 66 can be controlled manually, or can be controlled automatically through the use of certain of indicators associated with each of the weight 52 and the floating roller 58, in order to automatically maintain the proper speeds for testing the yarn end, and for relaxing the yarn end prior to entering the alignment guide 62.
  • the testing system will test for matters such as a poorly made splice, improperly tied knots, and physical flaws in the fiber bundle which forms the yarn end.
  • an additional advance is obtained, in that almost immediately after tension is placed upon a yarn end or all of the yarn ends in a sheet extending across the transport drums, the tension is relaxed by means of the grip of transport yarn drum 56 on the yarn end as it traverses the drum, and then passes down and around the relatively lightweight floating or dancer roller 58. In this manner, destruction of crimp configuration in the yarn is avoided.
  • a set of threading guide bars 68 are shown for each of the yarn transport drums 38 and 56.
  • the threading bars constitute elongated stainless steel polished rods having their ends cantilever mounted on the rear plate or framework 41 on which the bearings for the drums are mounted, these bars extending over and under the drums but displaced therefrom and with their axes parallel to the axes of the drums. They are spaced from the drums a matter of a few inches.
  • each yarn end can first be threaded around the threading bars without contacting drum 38.
  • the individual yarn end is then trained on the tension roller 46, the roller 54, and then around the threading bar 68 associated with the transport drum 56. Thence, the yarn is trained around the floating dancer roller 58, over the pulley 60, and through the guide 62 to the take up device.
  • the printing or coloring apparatus is indicated generally by numeral 6, and comprises an angle iron framwork 70 adapted by suitable longitudinal and vertical members to support bearings at the end of a plurality of print rollers. as well as other associated apparatus.

  • FIG. 5 which will now be referred to for details of the construction, only three top print rollers are shown, that is, the print rollers 78, 80 and 82, with bottom rollers 72, 74 and 76.
  • the reason for illustrating the additional set of rollers 84, 86 in FIG. 1 is to illustrate that as many sets of rollers may be added to the print dyeing apparatus as needed or desired.
  • FIG. 5 indicates beam 4 as mounted in front of the printing apparatus.
  • individual yarn ends 32 are passed through an aligning device or reed 90 in order to set them in a definite aligned parallel relationship as they leave beam 4. They then pass over a roll 92. From roll 92, they pass, through suitable aligning devices, to a non-slip driven transport beam 5 which is covered with a non-slip material such as rubber. From drum 5 the yarns 32 pass downwardly over a floating dancer roller 7 to again establish the proper yarn tension during passage through the printing device, and then up over a stationary roller 96. In order to be sure that the rotation of the yarn transport drum 5 accurately feeds yarn from the beam 4, the yarn encircles approximately 270 of the periphery thereof, and to this end, an additional stationary roller 98 is provided.

  • the yarn is allowed to fall naturally by gravity onto a Tefloncoated stainless steel yarn restraining slide or chute 114 and onto the conveyor belt 116 which leads into the hot box or steamer 8. In so falling, it will be noted that as the yarn ends of the web reach the conveyor belt, they fold gently one over the other to form what will be called hereinafter plaits. At this point, the yarns are in a completely relaxed condition.
  • one of the advantages of this invention is that prior to the drying mecha nism, the yarn is maintained in an untangled condition, and is kept in a controlled tension condition during the printing operation. Uniformity of the final dyed color of the yarn by this sequence of operations is much higher, as well as uniformity of printing being greater, than has been experienced in the prior art systems.
  • the chute enhances the above: As has been indicated, the yarn after dyeing by gravity from the last (exit) finned roller 112 onto the Teflon coated stainless steel chute 114. This chute is at an angle to the vertical of about 20, and as a result, since the yarn is still wet, the chute restains movement of the yarn and thus minimizes twisting. The chute also maintains under control the lateral alignment of the yarns.
  • the chute therefore prevents the yarn from tangling when it is deposited on the conveyor belt 116, and instead of haphazardly dropping downwardly and thus haphazardly folding on the conveyor belt, each individual yarn end tends to fold gently on top of itself and adjacent yarn ends, so that when the yarn ends are eventually withdrawn from the conveyor belt, little or no entanglement occurs.

  • the needle punched covering material is generally about l/32 inch thick, and three turns wrapped around the stationary roll 76, so that the total thickness is about 3/32 inch.
  • Below the stationary roll 76 is a dye pan 122 containing the requisite colored dye 124.
  • the dye pan extends the full length of the bottom roll, and the bottom roll can be, for example, about 4 feet.
  • a small tube 126 connects the dye pan to a dye control unit 128 which has mounted at the top thereof (but insulated therefrom) a dye level probe 130.
  • the probe 130 is adjusted at that point.
  • the dye probe is connected electrically by suitable connections 132 to dye pump control 134 which in turn is connected to dye pump 136 into which feeds the lower end of a dye supply tank 138.
  • dye pump control 134 which in turn is connected to dye pump 136 into which feeds the lower end of a dye supply tank 138.
  • the level in the dye control probe member 128 also drops the same amount, and the probe 130 leaves the surface of the dye. This breaks the connection to the dye pump control, which in turn starts the dye pump 136.
  • Dye then flows via the tube 140 to an infeed pipe 142 which lies over the dye pan 122.
  • Dye then flows into the pan until the level thereof, and thus the level of the dye in the probe pan 128, rises to the point that contact is again made with the dye probe 130. This will actuate the dye pump control and stop the feed of dye to pan 122.
  • a doctor roll or mechanism Mounted adjacent to the stationary roll 76 is a doctor roll or mechanism, the mounting being shown schematically, and comprising a lever 146 mounted by a pivot at one end 148 and carrying an adjustable slidable weight 150 thereon.
  • the end of the lever adjacent the roll 76 has a rotating roller 152 thereon which presses against the material-wrapped surface of the roll 76.
  • the weight By adjusting the weight, the amount of dye picked up by the material can be made greater or less, in order to adjust the amount of dye deposited on the yarn ends as they pass through the rolls.
  • Upper roll 82 is made of smooth, polished stainless steel.
  • the bearings 154 at each end of the upper print rolls 82 are adjustably mounted so that they may move upwardly, and vertically, and dowardly with respect to the print roll 76.
  • Each of these bearings is attached to the piston rod 156 of an air cylinder 158, an air cylinder being used for each end of a given upper roll.
  • a solenoid air supply control valve is provided, whose control will be described below. Air from the solenoid control valve, when the latter is actuated in one direction, will flow through a check valve 162 and into the top of the air cylinder 158, and piston 156 will begin to move downwardly. Air from the solenoid valve will flow through the check valve 166 when the solenoid valve is operated in the other direction, and will therefore pass into the bottom of the cylinder 158 to move piston 156 upwardly.
  • check valves 162 and 166 are of the kind in which air will pass rapidly therethrough and into the respective end of the cylinder, but air will pass therethrough in the opposite direction only slowly.
  • Solenoid valve 160 is provided with a suitable air supply 168, and an exhaust for the air which is forced out of the cylinder by actuation of the piston.
  • the solenoid valve, and the air cylinder together control the up and down motion of the upper print roller 82.
  • the air cylinder were designed both in length and operation so that the roller 82 would be moved rapidly down against the lower roll 76, the result would be either to damage the covering of the roll, damage the yarn passing therethrough, or would spatter dye over adjacent portions of yarn on which no dye is desired.
  • the function of the check valves 162 and 166 is to cushion the downward and upward motions of the piston 164, respectively. The operation is therefore as follows: When air is supplied by the solenoid valve to the cylinder 158 through check valve 162, it flows freely therethrough, and as a result the piston 164 moves very rapidly down toward the bottom end of the cylinder.
  • the distance A between the bottom of the piston 164 and the bottom end of the cylinder is made greater than the distance B between the nearest points of the perimeters of upper roll 82 and bottom roll 76.
  • the function of the check valve 162 permits this.
  • the solenoid control valve 160 is actuated so as to feed air through the check valve 166 rapidly to move piston 156 upwardly, and thus the roll 82 is moved rapidly and forcefully in an upward direction.
  • the air which previously has been at the top of the pis ton can now flow only slowly back through the check valve 162, with the result that while the initial motion of the roll 82 is rapid in an upward direction, yet as it approaches the upper end of its motion, the air within the cylinder becomes compressed and slows this motion so that the piston comes to a gentle stop at its uppermost position.
  • the operation of the solenoid valve is controlled by a control drum 174, that is, a drum type timer or other sequencing timer.
  • the drum is illustrated schematically in Flg. 6, and is shown and described in greater detail in reference to FIGS. 8 and 9.
  • the drum is equipped with projecting studs 176, 178, and 180. (These studs are numbered only by way of example).
  • Mounted in connection with the drum is a snap-acting switch 182 having a lever 184 for actuation thereof. When lever 184 is in a downward direction as illustrated, the solenoid valve is operated in one direction and when it is in an upward position (moved thereto by means of studs) the solenoid valve is actuated in the other direction.
  • the drum rotates clockwise, as illustrated by the arrow, and looking at the switch actuating stud 176 as an example, it is of intermediate length, and upon rotation of the drum the arm 184 will be moved upwardly to actuate the solenoid valve in a direction to move the piston 164 downwardly and bring the roller 82 into contact with the roller 76.
  • the lever arm 184 is in the upper position engaged by the stud 176, the yarn is printed with the color of the dye of pan 122.
  • valves 160 are shown, each one controlling the motion of a respective upper print roller 78, and 82. (ln dotted lines is shown a fourth valve which would control a fourth print roll 86 if used.)
  • control drums 174 are mounted in a common drive shaft 175 and are driven thereby. Shaft 175 is driven, as described above, by the outermost finned roll 112. Each drum controls a respective single solenoid valve 160.
  • each drum Positioned below each drum is mounted a snap switch 182 which is to be actuated by the projecting studs 174, 178, 180 et al., as described above.
  • the electrical circuitry indicated by wires 177, 179 and 181 for the connecting and operation of the valves 160 by a suitable line voltage 183 are shown schematically, and being conventional, are not further described herein, except to note that upon actuation of the drums, the engagement of a given snap switch follower by the studs of its respective drums, will cause only the one respective upper print roller to go through a printing cycle, irrespective of the operation of the other print rollers by their own snap-switches and valves.
  • a portion 174 of a drum is shown. It may be made of metal or suitable synthetic resin, and holes 186 radially extend inwardly from its periphery. the plugs or studs 176, 178, 180 and others as needed, are inserted in the holes.
  • the studs preferably have square heads, the edges of the heads of adjacent plugs touching so that a relatively smooth nondiscontinuous surface will be presented for engagement by the feeler arm or actuating button of the respective snap switch.
  • the studs may be made of a resilient synthetic plastic material, or soft rubber, with shanks that fit snugly into the holes 186.
  • the cylinder 158 can be a Wabco 3% by 3 inch air cylinder, Type No. PC601880030, made by WABCO Fluid Power Division, 1953 Mercer Road, Lexington, Ky.
  • the check valves 162 and 166 are each made by Skinner Electric Uniflow Valve Division, Edgewood Ave., New England, Conn. and are their flow control valves Fl3l-200.
  • the solenoid valves may be, for example, a Versa Type USG4522 made by Versa Products Company, Inc., 144 Coolidge Ave., Englewood, NJ.
  • the covering on the roller 76 can be a primary carpet backing such as a non-woven polypropylene, and the roller dips about one-half inch in the dye in the dye pan.
  • Doctor roller 152 is approximately 2% inches in diameter, is the full length of the roller 76, and is loaded so as to bear against the latter with a force of about 50 to 75 pounds.
  • Another feature of the invention is that all of the rollers at the output end of the printer to pull the web of yarns therethrough, are finned and the purpose of the finned construction is two-fold: the first is to obtain a much greater control of the yarn ends as they are pulled out of the printing apparatus, and the passing of the yarn ends over the outwardly projecting fins gives this kind of control as compared to what the lack of control due to slippage if no fins were used. ln addition, because the dye stutf on the yarns is still wet, it is de sired to keep the yarns out of contact with the surface of the output rollers. The fins do this by spacing the yarns from the surface of the rollers. The r llers themselves are approximately 4 inches in diameter.
  • each roller has four fins.
  • the fins extend approximately 1% inches from the peripheries of the rollers. are approximately one-eighth inch in thickness, extend the full length of each roller. and are made of stainless steel.
  • the fins are fitted into slots in the rollers, and welded therein.
  • control drum 174 is driven by the last exit finned roller 112.
  • the purpose of doing this is to maintain accurate control of the particular portion of the lengths of the yarn ends which are being dyed.
  • a chain drive mechanically connects the last finned roller 112 with the input shaft of an electrically actuated brake-clutch mechanism 190.
  • the output shaft of mechanism 190 is connected by a chain drive to the control drum 174.
  • Each of the rollers 110, 112 is driven by a single motor. and each roller is conventionally connected by drive means such as conventional sprocket wheels and chain linkages to each other.
  • any stopping of the printing apparatus takes place just as the top print roll 82 is about to lift from the bottom print roll 76.
  • the stopping of the printing mechanism is done. of course. by stopping the motor which drives the finned rollers 110 and 112. In some cases. such stopping for any length of time. will permit the wet yarn to elongate. and thus throw the printed sections (across a web of such yarns) out of their proper longitudinal sequence with respect to the position of the plugs l76l80 on the control drum. It is necessary to correct for this prior to starting up the printing apparatus again.
  • the brake-clutch mechanism 190 is a conventional one. and is controlled electrically by means of a manually operated push-button switch (not shown) which is connected to a suitable source of voltage such as l 15 to l2O volts AC.
  • a manually operated push-button switch not shown
  • Such brake-clutch devices are made by a number of people and are common on the market. Therefore. little description is necessary therefor except to say that when no control voltage is applied to the brake portion of mechanism 190, the clutch is normally in engagement and the brake is disengaged. so that as the roller 112 turns, it is enabled to turn the drum 174 as explained above.
  • the brakeclutch mechanism 190 is actuated by connecting it to the above voltage source through said manually operated switch. then the clutch becomes disengaged.
  • the mechanism is mechanically connected to the roller 112 and the timer drum 174, so that when the brake is applied. it holds the timer drum 174 motionless. Simultaneously, the clutch is disengaged, with the result that the rollers and 112 can be turned independently of the drum 174.
  • the push-button is operated to operate the brake-clutch control to apply its brake and thus hold the drum 174 motionless, and at the same time to disengage the clutch and permit freedom of rotation of the rollers 110 and 112.
  • the motor that runs the rollers 110, 112 is jogged by a manually operated switch (not shown) so that the yarn web is moved through the printing apparatus until the correct positioning of the rear end of a printed section is properly aligned with the selected pair of print rollers.
  • the brake is disengaged so that the timing drum is again driven by the roller 112.
  • FIG. 6 A further important feature of the invention is illustrated in FIG. 6, in that the yarns 32 pass the print rollers 76 and 82 in a slanting direction, the yarn ends passing over an upper guide roller 106 before each set of print rollers. and over a guide roller 108 (or under a guide roller 104) at the down stream side of each set of print rollers.
  • This slanting relationship of the yarn end 32 as it passes between the rolls is a special feature of the invention and its purpose is as follows:
  • the capillary action of the covering on the bottom roller 76 is then enabled to quickly flatten out the dye stuff puddle which remains on the roller 76 instead of adhering to the yarn ends and passing therewith to the next set of printing rollers. As a result. printing accuracy is greatly enhanced by this angular relationship.
  • the dye fixation apparatus consists of an elongated chamber adapted to receive the upper reach of the conveyor belt 116, the chamber having an entrance roll 194 and exit roll 196 over which the conveyor belt is trained. Suitable rollers may be used, if desired, on the underside of the box to support bottom reach of the conveyor belt.
  • the conveyor belt itself is of open mesh construction to permit air or stream to pass easily through it, and on the inside of the chamber slides along a support which is preferably perforated for transmission therethrough of steam. Steam pipes lead into the box itself, beneath said support, and thus beneath the upper level or reach of the belt and is thus enabled to pass upwardly through the yarn on the belt.
  • Means are provided for heating the roof of the chamber, which prevents steam condensation and makes possible temperatures in the chamber of the order of 210 to 230F.
  • Air locks 198 are provided at each end of the steam chamber (a portion only thereof being indicated at the left-hand end as drawn of FIGS. 1 and 2), these locks being fitted with suitable exhaust means that are used to purge air from the steam chamber, carry off excess steam from the latter, and cool the yarn before it exits from the chamber.
  • steam passes upward through the belt and through the yarn while heat is radiated down the yarn from the chamber roof. Fixation of the dye stuff onto the fiber is brought about by a yarn dwell time of l to 5 minutes in the steam chamber at said temperatures.
  • belt 116 After belt 116 exits from the chamber, it passes through the nip of two rolls, one of these being the exit roll 196 on which the conveyor belt is trained, and the other being a top nip roll 200. It is important to note that the tensionless yarn on the belt is not withdrawn from the latter until the yarn has passed through the nip of rolls 196 and 200. In this manner, it will be found that the individual yarn ends will be withdrawn from the conveyor belt without entanglement.
  • the yarn ends pass over curved slide member 202 which because of its curvature will tend to restrain the yarn and keep it in alignment, and then the yarn ends pass around a floating tensioning roller 204 which is enabled to move horizontally, and which exerts a constant tension on the yarn and tends to equalize any unevenness in yarn length up to this point.
  • the roller 204 may be actuated by suitable weights, similarly to the roll 46 of the testing device, or can be actuated by other means. Switches, not shown, operated by roller 204 operate the drive motors for the succeeding steps.
  • the embodiment comprises a plurality of rollers 210, 212, 214, 216, 218, 220 and 222.
  • Rollers 210, 214, 218 and 222 are of stainless steel with smooth surfaces. These rollers are long enough to accommodate the entire sheet of yarn ends.
  • the rollers 212, 216, and 220 are of stainless steel and are covered with the same kind of covering material used to cover the bottom print rollers 72, 74, 76 and 78, and can be several turns of a non-woven polypropylene carpet backing material.
  • the rollers 212, 216 and 220 are movable horizontally by manually operable controls illustrated schematically by numeral 224 so that the bite or nip between the rollers 212, 216 and 220 and their adjacent rollers 210, 214, 218 and 222 may be adjusted for the particular yarns being washed.
  • Each of the rollers is driven by conventional means (not shown). Water is fed by means of manifolds 223 onto roller 214 at the nip between it and roller 212.
  • the rinse water for the washing apparatus feeds by gravity downwardly, with the result that the cleanest water (incoming) is applied to yarn material which has progressed upwardly through the apparatus and has been previously washed lower in the ladder of wash rollers.
  • a drain pad 226 is used to collect and carry off the drain water. It will also be noted that the yarn travels in a serpentine path around the rollers in such direction that the yarn encircles a major portion of the periphery of each roller as it moves upwardly.
  • a guide 225 may be used if desired.
  • the material which covers the rollers 212, 216 and 220 has a capillary action which assists in withdrawing moisture from the yarn, and particularly in respect to roller 212 which is the uppermost roller.
  • the direction of rotation of the rollers is such that the yarn passes through the nip between rollers 210 and 212 after the introduction of rinse water from the infeed manifolds 223.
  • the capillary action of the covering material acting on the final passage of the yarn through the last nip assures a low and uniform moisture content in the yarn.
  • the yarn enters the roll stack at the bottom and follows a serpentine path around the rollers to the top.
  • the cascading water and the squeezing action of the rollers effectively wash out any unfixed dye material from the yarn.
  • the quantity of water needed with this method is greatly reduced since the water is used several times during its passage down the rollers.
  • each covered roller is squeezed at two opposite sides rather than one as is normally the case for the series of two roller wringers. This doubles the number of wrings for any given number of wrapped rollers. or half the number of wrapped or covered rollers is needed for any given number of wringings.
  • rollers 212, 216 and 220 are covered with water absorbing material.
  • rollers 210. 214, 218 and 222 could be covered, and rollers 212, 216 and 220 be bare.

  • Chamber 12 is shown schematically and comprises an elongated chamber having four hot air inlets at l3. l5, l7 and 19 leading into the chamber at the top so that the chamber basically is divided into four zones through which air passes downwardly and through the yarn.
  • the yarn ends are then led to a set of finned rollers 230, and from the latter the yarn is deposited on a chute 232 made of stainless steel.
  • Chute 232 restrains the yarn ends as they come from the finned rollers so that the yarn ends fall by gravitational force gently in overlapping plaits on the end of an open mesh conveyor belt 234.
  • the conveyor belt is trained on entrance rollers 236 and exit rollers 238. Because of the open mesh of the belt, air can pass freely through it and yarn deposited thereon.
  • the chamber has conventional means (not shown) for removing air from under the top reach of the belt, ex hausting part of this air, adding fresh replacement air, heating the incoming air, and forcing the latter from above the upper reach of the belt and downwardly through the upper reach of the belt.
  • the yarn as described above, is in plaits in a relaxed state on the belt, and passes through the hot air chamber in this condition so that the exposure of the yarn to the hot air moving through it makes for fast efficient drying and stress relieving.
  • the nip roller 240 At the exit end of the chamber, there is provided the nip roller 240 and just as has been described above for the exit rollers from the steam chamber, the yarn is not withdrawn from conveyor belt 234 until the yarn plaits have passed between the nip of rollers 238 and 240.
  • Configuration of the drying chamber is such that after the yarn is dried, its temperature may be effectively and uniformly raised to the heat setting temperature for the thermoplastic yarn. It is thus possible to stress relieve or heat set a thermoplastic yarn in the same hot air chamber. It has been found that in order to do this, and assuming that functionally the chamber is divided along its length into four zones, the temperature of drying can be applied during the first three zones moving from left to right as drawn in FIGS. 1 and 2, and then in the last zone which would be approximately onefourth of the lengnth of the chamber, the
