Definitions

  • Two or more yarns are often twisted or “cabled” together to form plied yarns having various properties useful in the construction of soft floor coverings (i.e., tufted rugs and carpets).
  • a standard cabling process involves physically rotating one yarn, fed from a creel, around a second yarn fed from a “bucket”, both yarns being under carefully controlled tension, and then winding up the combined yarns in the form of a single, cabled (plied) yarn package.
  • Machines to perform this operation are sold by various manufacturers, including: Oerlikon (Volkmann), Rieter (ICBT), China Textile Machinery Corporation (CTMC), Belmont, and the like. These machines typically include a creel to hold one or more feed yarns; a tension frame to control creel yarn tension; a tube to convey the creel yarn to a spindle; a “bucket”, located above the spindle, containing the second feed yarn; tension devices; a bucket lid; and an extension arm (located no more than about 7 inches from the top of the bucket) to combine the bucket yarn with the creel yarn traveling around the bucket yarn at specified speed).

  • Belmont Belmont, and the like.
  • These machines typically include a creel to hold one or more feed yarns; a tension frame to control creel yarn tension; a tube to convey the creel yarn to a spindle; a “bucket
  • Twisting technology is one of the limitations of the carpet industry because although twisting is important to achieve the density and resilience required of tufted carpet, cabled yarns are processed relatively slowly compared to the preceding and subsequent processes. As a result of this industry “bottleneck”, a relatively large investment in twisters and process inventory is required.
  • Yarns are twisted together at frequencies ranging from about one turn to more than eight turns per inch, depending on yarn thickness and the intended effect. The higher the number of turns per inch the slower the operation becomes as the spindle carrying the creel yarn must complete a revolution for each “turn”. For example, if two yarns are twisted at about 6000 rpm, at a frequency of two turns per inch, the winding speed of the product will be approximately 3000 inches (83 yards) per minute, neglecting other factors. Doubling turn frequency to four turns per inch would approximately halve the production rate (assuming the yarns are thin enough to permit the higher level of twist). Winding speed for a commercial twisting operation is usually about 50 yards per minute up to about 100 yards per minute achieving rotational speeds of 6000 up to claims of about 9000 rpm for lighter deniers.
  • embodiments of this disclosure include yarn twisting or cabling apparatus, and the like.
  • One exemplary yarn twisting or cabling apparatus includes: a multi-package bucket having a bucket top and a bucket bottom, a reserve disc, and an adjustable extension arm with a balloon thread guide, wherein the multi-bucket is adapted to include at least two full size 11 inch tubes, wherein the reserve disc is disposed at the bucket bottom, wherein the adjustable extension arm is positioned so that the balloon thread guide is positioned above the bucket top along the center line of the bucket.
  • Another exemplary method of twisting or cabling yarn includes: providing an apparatus yarn twisting or cabling apparatus as described herein that includes a multi-package bucket; and twisting a bucket yarn with a creel yarn to form a piled yarn.
  • FIG. 1 illustrates an embodiment of a yarn twisting or cabling apparatus including an embodiment of a double-bucket.
  • Embodiments of the present disclosure will employ, unless otherwise indicated, techniques of fibers, yarns, textiles, processes with making yarn, and the like, which are within the skill of the art. Such techniques are explained fully in the literature.
  • fiber refers to filamentous material that can be used in fabric and yarn as well as textile fabrication. One or more fibers can be used to produce a fabric or yarn. The yarn can be fully drawn or textured according to methods described herein.
  • the term “cable” or “cabling” refers to twisting together two or more yarns.
  • the term “cabled yarn” refers to two or more yarns twisted together.
  • conventional twister refers to a system of producing a yarn by twisting together two or more single yarns simultaneously.
  • folded yarn or “plied yarn” is a yarn in which two or more single yarns are twisted together in one operation (e.g., two-folded yarn (two-ply yarn), three-fold yarn (three ply yarn), and the like).
  • Embodiments of the present disclosure provide for multi-package buckets (e.g., double bucket), systems and methods of forming yarn, apparatus for twisting or cabling yarn (also referred to as “yarn twisting or cabling apparatus”), and the like. Embodiments of the present disclosure reduce how often bucket doffing is performed. The standard industrial doffing procedure is to remove the bucket package and replace it when it is depleted to one half.
  • the time between each doff cycle triples if a double-bucket (e.g., sized to include two full size tubes and the tube yarns are tied to one another) is used instead of a single tube bucket (sized to include a single tube).
  • a double-bucket e.g., sized to include two full size tubes and the tube yarns are tied to one another
  • the time between doff cycles increase five fold if a triple-bucket is used. Increasing the time between doff cycles may result in limiting downtime thereby increasing the efficiency. Also the less doffing required per pound of yarn, the fewer employees required for processing that yarn, thereby decreasing labor costs.
  • Embodiments of the present disclosure include multi-package buckets that can be used on a conventional yarn twisting or cabling apparatus or on high-speed yarn twisting or cabling apparatus.
  • embodiments of the present disclosure use two or more bulk continuous fibers or synthetic yarns (e.g., nylon or other polyamides) to create a plied yarn (two-ply, three-ply, or more) that can be used in textiles such as rugs, carpets, and the like.
  • An embodiment of the present disclosure includes a multi-package bucket that can include 2, 3, 4, or more full sized (11 inches) tubes (e.g., yarn tube or yarn package). Each additional tube can increase the time between each doff cycle by a factor relative to a bucket including a single full size tube, where the factor can be determined using the following formula: ((A ⁇ 2) ⁇ 1), where A is the number of tubes.
  • the factor is 3, so that the time between doff cycles increases by a factor of three relative to a bucket including a single full size tube doffed when half depleted.
  • the yarns of each of the tubes are tied to one another to form a continuous yarn.
  • the end of the yarn of the first tube or top tube is tied to the start of the yarn of the second tube or bottom tube so that once the first tube is completely unwound, the yarn of the second tube is taken up.
  • the end of the yarn of the first tube or top tube is tied to the start of the yarn of the second tube or middle tube, and the end of the second tube is tied to the start of the yarn of the bottom or third tube. Initially, the first tube will unwind, and then the second tube will unwind since the end of the first tube is tied to the start of the second tube.
  • top tube refers to the tube located at the top of the multi-bucket.
  • bottom tube refers to the tube located at the bottom of the multi-bucket.
  • middle tube refers to one or more of the tubes located between the top tube and the bottom tube.
  • the tubes (2 or more) are disposed on a device (e.g., a tube transfer spindle housing).
  • the tubes can be tied together before or after being disposed onto the device.
  • the device can be disposed into the multi-bucket and connected to a yarn twisting or cabling apparatus.
  • Embodiments of the device may limit the amount of time during bucket doffing.
  • the height of the bucket and the distance from the balloon thread guide to the reserve disc can be increased according to the increase associated with adding each tube.
  • the bucket height may increase by about 11-13 inches per addition of each tube. The exact height increase depends upon the design of the apparatus for twisting or cabling yarn, the type of yarn, and the like.
  • the diameter of the multi-package bucket may increase so that the tube package can (tubes loaded on the tube transfer spindle housing) be inserted and removed from the multi-package bucket. In an embodiment, the diameter of the multi-package bucket is greater than the diameter of the yarn package.
  • the multi-package bucket can be used in embodiments of the yarn twisting or cabling apparatus.
  • the multi-package bucket can be used in a standard yarn twisting or cabling apparatus.
  • the yarn twisting or cabling apparatus is a high speed yarn twisting or cabling apparatus, such as that described in Attachment A.
  • FIG. 1 An embodiment of a yarn twisting or cabling apparatus 10 including a double-bucket 12 is shown in FIG. 1 .
  • FIG. 1 is not intended to limit the yarn twisting or cabling apparatus to a double-bucket system; rather FIG. 1 illustrates an implementation of the multi-package bucket system, and this implementation can be extended to multi-package bucket systems having 3 or more tubes.
  • the yarn twisting or cabling apparatus 10 includes a creel peg (not shown), a tension frame (not shown) (controls creel tension), tube transfer to spindle housing (not shown), spindle (not shown), “bucket” 12 , bucket tension devices 14 , bucket top 16 , reserve disc 18 , and an adjustable extension arm 22 with balloon thread guide 24 .
  • the dimensions (e.g., the height) of a double bucket 12 increased to include two full length tubes (first tube 42 a and second tube 42 b ), in contrast to some systems including two half tubes or a system including a single tube. This is advantageous because the tubes are doffed less often than current systems since the tubes are doffed when the tube is half full.
  • embodiments of the present disclosure are doffed once one and a half tubes are used as opposed to only a half tube being used.
  • the doff cycle triples compared to using a single tube bucket.
  • the double-bucket 12 can have a height of about 30 to 36 inches.
  • the size of the double-bucket 12 can be increased because the balloon thread guide 24 can be moved to a larger distance from the reserve disc 18 (e.g., about 27.5 to 68, about 30 to 50, or about 30 to 42 inches from the reserve disc 18 to the balloon thread guide 24 ), or from the top of the double bucket 12 to the balloon thread guide 24 .
  • the balloon thread guide 24 could be moved in less than about 1 inch increments within the ranges noted above (e.g., the lower range could be about 28, 29, 30, 31, 32, 33, 34, 35, and so on, while the upper limit could be 68, 67, 66, 65, 64, 63, 62, 61, and so on, and combination of these lower and upper levels).

  • the reserve disc 18 can have a diameter of about 7 inches, and the distance 42 from the reserve disc to the balloon thread guide 24 can be about 28 to 68 inches, about 30 to 58 inches, or about 30 to 48 inches.
  • a creel yarn (first yarn) 32 is disposed on the creel peg.
  • the creel yarn 32 is guided through the tension frame and to the reserve disc 18 .
  • the tension applied to the creel yarn 32 is about 100 g to 1000 g or about 200 g to 300 g.
  • the creel yarn 32 is wrapped around the reserve disc 18 about 0.75 to 2.5 wraps.
  • the creel yarn 32 is guided to the balloon thread guide 24 (forms the balloon 36 ), where it is cabled with the bucket yarn 34 .
  • the bucket yarn 34 is disposed in the double-bucket 12 .
  • the end of the bucket yarn 34 of the top tube 42 a is tied to the start of the bucket yarn of the bottom tube 42 b to from a continuous bucket yarn 34 .
  • the bucket yarn 34 is guided through the bucket tension devices 14 to the balloon thread guide 24 , where it is cabled with the creel yarn 32 .
  • the balloon formed during operation is large enough to pass around the bucket.
  • the bucket tension is about 100 g to 1000 g or about 200 g to 300 g. It should be noted that not all of the features of the apparatus are described for reasons of clarity and one skilled in the art would know how to properly set up the apparatus to run the twisting or cabling process.
