  • the novel dyeing machine of the present invention indicated generally at 10 is adapted to receive a plurality of elongated strands of textile material, as for example yarn, 12 from a creel or a similar supply unit not shown. It is advantageous to supply the strands 12 from a creel which may include attachments, known to the art, for tying in new strands, the strands being fed through the machine so that a neverending input supply of material is provided.
  • the dyeing machine 10 includes an input station 14 which operates to receive and arrange the incoming strands 12 before such strands are fed to subsequent stations of the dyeing machine. It should be noted that the operation performed by the dyeing machine 10 is a continuous operation and the strands 12 are threaded through the complete machine so that diverse steps are being simultaneously performed by the various stations of the dyeing machine upon different portions of the strands.
  • the components of the input station 14 include a stationary split rod 18, a separator comb or reed 20, and feed rolls 22 and 24 which are mounted upon the framework 16 of the machine 10.
  • the yarn or other textile strands which are fed into the dyeing machine pass on either side of the split rod 18 which separates the incoming strands into two substantially flat sheets of yarn. These sheets may then be easily arranged and combed back into a single sheet by the reed or comb 20.
  • additional split rods 18 may be employed if the volume of the strands being fed into the machine is particularly large, and in such cases, it may be necessary to divide the strands into more than two horizontal sheets before they are fed to the comb 20.
  • the comb 20 is conventional in construction and includes a large number of detents for separating and arranging the strands 12.
  • the strands are passed from the comb 20 over the rollers 22 and 24 and beneath a walkthrough 26 which also forms a part of the input station 14.
  • Walkthrough 26 extends transversely across the width of the dyeing machine 10, and is strategically positioned between the remainder of the input station 14 and the subsequent dyeing station 28. This location of the walkthrough 26 is of utmost importance if the dyeing machine 10 is to operate efficiently, for from the walkthrough 26, an operator may control the dyeing machine while inspecting the incoming strands 12 before they pass through the dyeing station 28.
  • the operator may remove any broken or frayed strands and is afforded easy access to the remaining strands passing through the dyeing station 28. Therefore, the operator may remove or repair broken or tangled strands before such strands are passed through the dyeing station 28 and on to cause further complications in subsequent stations of the machine 10.
  • the strands 12 pass from the roller 24 across a roller 30 which is supported beneath the walkthrough 26 to a roller 32 and a split bar 3 4 which are also supported by the walkthrough 26.
  • the split bar 34 operates as does the split bar 18 to divide the strands 12 into a plurality of sheets, each of which contains a number of individual strands arranged in substantially the same horizontal plane.
  • the strands 12 pass into the dyeing section 28.
  • the strands are first fed to an oscillating comb or reed 36 in the dyeing section which arranges the strands in substantially the same horizontal plane while imparting a lateral reciprocating motion to the strands.
  • oscillating comb or reed 36 in the dyeing section which arranges the strands in substantially the same horizontal plane while imparting a lateral reciprocating motion to the strands.
  • the reciprocating comb 36 includes a comb support block 38, the upper surface of which supports a plurality of spaced, vertically extending comb teeth 40.
  • the portion of the oscillating comb 36 which is formed by the comb support 38 and the comb teeth 40 is substantially identical in construction to the other stationary combs employed in the dyeing machine 10 such, as for example, the comb 18.
  • the comb teeth 40 may be of any construction suitable to provide detents which receive and guide strands of material passing therethrough, and the number of teeth 40 may be determined by the number of strands which the comb is designed to receive.
  • the comb support 38 is mounted for reciprocating lateral movement in a stationary guide 42 which forms a box-like structure having a bottom wall 44, side walls 46, end walls 48, and a top wall 50.
  • the top wall is provided with a transverse slot extending completely across the top wall between the end walls 38 to permit the comb teeth 40 to project outwardly beyond the surface of the top wall 50.
  • the guide 42 is mounted upon suitable sup- 4 ports 52 which are connected to the dyeing machine frame 16.
  • the comb support 38 has a projecting lug 54 which extends downwardly from the bottom portion of the comb support through a slot 56 formed in the bottom wall 44 of the guide 42.
  • the slot 56 permits the lug 54 to move laterally across the guide 42.
  • the lug 54 is connected to a motor 56 by means of a linkage 58. It is obvious that reciprocating movement of the comb support 38 can be achieved by using various cam arrangements or other known mechanical linkages, and the linkage 58 is illustrative of only one such arrangement.
  • the linkage 58 in FIGURE 3 is connected to a drive eccentric 60 which in turn is rotated by the motor 56. Upon rotation of the drive eccentric 60, the linkage 58 is caused to reciprocate the comb support 38 laterally with respect to the guide 42, therefore resulting in reciprocal movement of the comb 40.
  • the comb 40 in turn causes the strands 12 of textile material which are passing through the comb to reciprocate laterally.
  • Blanket 64 can be formed from a belt of resilient rubber or plastic material, and it is this resilient belt which forms a backing for the strands 12 during the actual dyeing process occurring in the dyeing section 28.
  • the blanket 64 passes over a large motor driven drive cylinder 66 and a plurality of guide rollers 68.
  • the guide rollers 68 and the drive cylinder 66 are mounted upon the frame 16 of the dyeing machine 10, and the drive cylinder is driven by an electric motor 70.
  • the resilient blanket 64 constitutes an important component in the dyeing section 28 and is therefore worthy of specific consideration.
  • the blanket 64 travels about the drive cylinder 66 and the guide rollers 68 and, at a point subsequent to the drive cylinder 66, passes through a washing solution maintained in a reservoir 72.
  • the brush 74 catches and removes broken strands of material from the blanket 64, while the scraper 78 and the brush 76 operate to remove excess dye stuff from the surface of the blanket.
  • the brush 74 prevents stray strands from clogging the remainder of the washing apparatus, while the scraper 78 and brush 76 remove all excess dye stuff and apply washing and lubricating liquid from the reservoir 72 to the surface of the blanket.
  • the blanket 64 As the blanket 64 receives the laterally moving strands 12 from the oscillating comb 36 and guides the strands about the drive cylinder 66, the blanket also oscillates laterally in a random manner, thereby imparting an additional random oscillation to the strands 12.
  • This random oscillation of the blanket may be perpetuated by one of the guide rollers 68, as for example guide roller 68a in FIGURE 1, which is illustrated in detail in FIGURE 4.
  • the guide roller 68a is mounted upon a pivoted support 80 which in turn is mounted for movement about a pivot point 82 on a stationary support 84.
  • Stationary support 84 may be secured to the side frame of the dyeing machine 10 in any suitable manner.
  • the width of the blanket 64 is less than the length of the guide roller 68a, so that as the support 80 is rocked or tilted about the pivot point 82, the blanket 64 moves laterally of the roller 68a.
  • micro switches 86 and 88 which are secured to either side of the support 80 adjacent the outer ends of the roller 68a.
  • the micro switches 86 and 88 are 'opertively connected to solenoids 90 and 92, which are mechanically linked by linkages 94 and 96 to opposite corners of the support 80. It should be noted that micro switch 86 on the left side of the support 84 in FIGURE 4 is electrically connected to operate solenoid 90 on the right side of the support, while micro switch 88 is connected in the same manner to operate solenoid 92.
  • solenoid 92 is activated and causes the support 80 to pivot about the pivot point 82 to reverse the lateral movement of the blanket 64, the blanket moves toward the micro switch 86.
  • the micro switch 88 is released and the circuit to the solenoid 92 is opened. Therefore, subsequent contact between the blanket 64 and the micro switch 96 results in the energization of the solenoid 90 and movement of the blanket 64 back toward the micro switch 88.
  • This oscillatory movement of the strands 12 is employed to achieve the dyeing of single strands of material with a multiplicity of colors.
  • the oscillatory lateral movement of the strands 12 is a random non-repetitive movement, the pattern of colors applied to each strand of material will be correspondingly random and non-repetitive.
  • This movement is achieved through the random movement of the blanket 64, and may be further enhanced by causing random oscillation of the oscillating reed 36 by means of cams or other well known mechanical linkages. Such linkages transform and transmit the rotary movement of the motor 56 to the comb support 38 as a random oscillatory movement.
  • guards may be positioned at either end of the roller 68a adjacent the edges of the blanket 64 to prevent the blanket from moving into contact with either of the micro switches 86 or 88.
  • a repetitive oscillatory movement of the elongated strands 12 may be achieved by instituting a controlled lateral oscillation of the comb or reed 36.
  • the oscillation of the reed 36 in a repetitive pattern can be obtained by causing the comb support 38 to follow a single cam connected to the motor 56, or by other known mechanical linkages which transform a rotary motion into a repetitive oscillatory motion.
  • this dyeing operation may be easily achieved by locking the blanket 64 against lateral movement and also de-energizing the motor 56 so that no oscillatory movement is imparted to the strands 12 by the oscillatory comb 36. In this case, the strands are then guided by the blanket 64 and no relative lateral movement occurs.
  • FIGURES 5 and 6 illustrate in detail the novel dyeing mechanism employed with the dyeing machine 10.
  • the blanket 64 passes between the drive cylinder 66 and a plurality of dye distributor rollers 98.
  • the distributor rollers 98 are driven in synchronism by a motor 99.
  • any suitable number of distributor rollers 98 may be positioned in contact with the blanket 64.
  • the rollers 98 as may be noted from FIGURE 5, are mounted upon a transverse support 100 which is in turn mounted upon the side frame 16 of the dyeing machine 10.
  • the distributor rollers may be moved either into or away from contact with the blanket 64 by rotating the support 100.
  • Each individual distributor roller 98 is mounted for rotation upon the support by means of depending mounts 102 which connect with a roller axle 104.
  • the mount 102 may be a spring mount including springs 106 which operate to press the distributor cylinder 98 into contact with the resilient blanket 64.
  • the supports 100 for each individual distributor roller 98 are positioned in the side frames 16 of the dyeing machine 10 so that the distributor rollers are sequentially disposed about the surface of the drive cylinder 66 as illustrated in FIG- URE 1.
  • the dye distributor rollers 98 of the dyeing machine 10 are not only of equal diameter, but additionally the roller synchronization problems which often prevailed with previous dyeing units have been further eliminated by providing the distributor rollers 98 with a dyeing surface which extends about the complete circumference of the distributor rollers.
  • the dye distributor rollers 98 produce a continuous rather than an intermittent dyeing operation, and the maintenance of accurate synchronization between distributor rollers becomes less critical.
  • Each of the dye distributor rollers 9-8 is provided with an engraved dye applying section 108 which extends circumferentially about the roller for a portion of its width.
  • the engraved dye applying sections 108 of succeeding rollers 98 are offset laterally from the dye applying sections of all proceeding rollers.
  • the dye applying section of any individual dye distributor roller is misaligned laterally with respect to the dye applying sections on each proceeding and succeeding roller.
  • the dye applying section 108 on any distributor roller should be positioned to commence at a point which is in line with the termination point of the dye applying section on the preceding roller.
  • the dye distributor rollers 98 do not operate in the same manner as the conventional printing rollers which have previously been used for the dyeing of elongated textile strands.
  • these printing rollers have employed roughened or engraved surfaces which contact dye or other coloring material maintained in fluid state within a reservoir, positioned below the roller. These roughened surfaces of the roller receive and lift a portion of this coloring material from the reservoir and subsequently transfer it to the surface of a strand.
  • Such printing techniques do not achieve strand saturation, but only result in surface printing of a strand, and therefore a printing technique is not acceptable for the effective printing of multifilament strands which should be saturated with coloring matter for complete filament dyeing.
  • each dye distributor roller 98 of the present invention achieves this strand saturation by employing deeply etched dye distributor sections which constantly receive a large supply of dye or other coloring material from a novel supply structure.
  • This supply structure is well illustrated by FIGURES and 6, where it will be noted that each dye distributor roller 98 is provided with a doctor blade 110.
  • the doctor blade 110 is supported upon a support arm 112 which may be mounted upon the shaft 104 of the distributor roller or which may extend independently from the roller support 100.
  • the doctor blade 110 contacts the engraved surface of the dye applying section 108' and operates to evenly distribute a pool of dye or other coloring material over the surface of the dye applying section.
  • the doctor blade 110 is provided with side walls 114 so that the doctor blade, in combination with the side walls and the surface of the distributor roller forms a reservoir for a pool of dye or coloring material.
  • This coloring material is furnished to the reservoir by a supply tube 116 which extends from dye containers 118 suspended over the distributor rollers 98 by a support 120.
  • the flow of dye or coloring material from the containers 118 may be con trolled by a manual valve, but ideally, this supply is controlled by an electric valve 122 positioned on the lower portion of the dye container 118.
  • the electric valve 122 may be any one of a number of conventional electric valves which is adapted to operate in response to a level-sensing mechanism so that the valve 122 will be actuated in accordance with the level of the liquid dye present on the doctor blades 110.
  • a liquid level senser 124 is mounted on the side wall 114 and is electrically connected by a connection 126 to control the valve 122 in response to the level of dye on the doctor blade.
  • the dyeing station 28 is particularly adapted to achieve the effective dyeing of elongated strands composed of a plurality of individual filaments, and therefore the dyeing machine can be employed efiiciently to process yarns or similar multifilament strands of textile material.
  • the dye distributor rollers 98 saturate these strands with dye or coloring material while pressing each strand into the resilient blanket 64 to insure thorough dyeing of each strand. Additionally, the combined action of the reciprocating comb 36 and the blanket 64 minimize strand separation and filament abrasion.
  • the blanket 64 is continuously lubricated in the wash reservoir 72 so that the strands 12 slide easily over the surface of the blanket as they are reciprocated by the comb 36, and the reciprocation of the comb 36 combined with the lateral movement of the blanket 64 causes the strands 12 to roll across the surface of the blanket, thereby tightening the individual filaments within each strand to preclude strand separation.
  • the continuous washing of the blanket 64 in addition to providing a lubricant for the blanket, also removes all dye stuffs from the blanket to prevent smudging of the incoming strands by residual material on the face of the blanket.

  • the front wall of the fixing unit 128 is provided with an opening 130 through which the strands 12 pass when entering and leaving the unit. As the strands 12 are saturated with unset dye or coloring material when they enter the fixing unit 128, it is important that such strands no not contact the surface of the unit surrounding the opening 130.
  • the fixing unit is mounted upon the dyeing machine 10 in such a manner that the strands are fed from the belt 64 into the fixing unit without contacting the surfaces surrounding the opening 130.
  • Mounted for rotation within the fixing unit 128 are a plurality of guide rollers 132 which propel and guide the strands 12 through the fixing unit.
