Definitions

  • the present invention relates to a feeding system for a "Core Spun” yarn ring-spinning machine, a “Core Spun” yarn ring-spinning machine which comprises said system and a method for spinning "Core Spun” yarn using said system.
  • the present invention relates to a feeding system adapted to continuously spin "Core Spun” yarn combining one, two or more continuous filaments of a given elasticity with coating fibres.
  • the continuous filaments of the core of the "Duo Core spun” yarn have different modulus of elasticity, so that those with lower elasticity retain those with greater elasticity, facilitating recovery of the fabric made with this yarn.
  • "Duo Core” yarn allows the production of fabric with high recovery and high dimensional stability (garments do not lose their shape with use) which are highly appreciated by consumers.
  • the fabric made with "Duo Core” yarn has a finishing of cotton fibres or the like which allows for more aggressive finishings (holes, special rinsing) than those tolerated by traditional elastic articles.
  • the elastomeric filament of Lycra ® elastane fibre is combined with a semi-elastic continuous filament of bi-component polyester T-400 ® brand by INVISTA to obtain high quality "Duo Core Spun" yarn.
  • This continuous T-400 ® filament by INVISTA is a filament of the generic elastomultiester fibre that is obtained by extrusion from the combination of different polymers ( Directive 2006/3/CE, OJ L 5, 10.1.2006 , p.14 , added this new elastomultiester fibre to the list of generic names of fibres).
  • Elastomultiester fibre filaments have the advantage that they can be used directly after the extrusion without being subjected to a texturing process, but the disadvantage is that the winding process subsequent to extrusion determines and limits the supply of these filaments to a very specific bobbin format.
  • the elastomultiester fibre filament is replaced by an elasticized continuous filament of textured polyester.
  • This filament can be used to manufacture "Duo Core Spun" yarn, but has the disadvantage of being supplied in bobbins whose format differs from that for elastomultiester fibre filament.
  • This different format bobbin requires the installation of a creel at the top of the machine ("overhead creel") from which the filament must be unwound "in defilé”.
  • This overhead creel enables a distance between spinning positions (spindles) of less than 80 mm to prevent the machine from losing yarn production output, but it requires the presence of a specific feeder device configured to positively feed, with controlled drafting, the filaments unwound "inenginelé". This device is not suitable for the "déroulé" unwinding of filaments from elastomultiester fibre bobbins.
  • the object of the present invention is to provide a feeding system for a "Core spun" yarn ring-spinning machine, which has the advantages described below.
  • the present invention provides a feeding system for a "Core Spun" yarn ring-spinning machine, comprising;
  • the feeding system claimed has the advantage of adapting to different continuous filaments, supplied on different format bobbins, so that a single machine can be used without being modified to produce "Core Spun” yarn with continuous elastomultiester fibre filament, or alternatively, to produce "Core Spun” yarn using elasticized continuous filament of textured polyester.
  • continuous filaments of textured polyester and elastomultiester fibre are supplied in a different bobbin format that requires a different unwinding system.
  • continuous filament of textured polyester is supplied with a bobbin format whose tube length exceeds 150 mm requiring the bobbins to be placed on a creel ("overhead creel") of the machine from which the filament must be unwound "inenginelé”.
  • elastomultiester fibre bobbins have a tube length which allows them to be unwound "inraité” using devices which actuate the rotary motion of the bobbins.
  • the system incorporates an accessory tool configured to actuate the dragging of the textured polyester filament from the creel when a bobbin of elastomultiester fibre is not present.
  • an accessory tool configured to actuate the dragging of the textured polyester filament from the creel when a bobbin of elastomultiester fibre is not present.
  • the tool claimed has the advantage of being configured to actuate the simultaneous dragging of two continuous filaments which may be individually fed to two adjacent spinning positions.
  • the other actuator another pair of rotating cylinders of the machine located at the upper position is left free.
  • this device can be used to actuate the unwinding of a third filament "Core Spun" yarn.
  • a versatile machine is obtained that adapts to different bobbin formats and is able to produce different types of "Core spun” yarn with a single feed system.
  • the machine claimed is suitable for manufacturing "Core Spun” yarn with a core that can combine up to three continuous filaments.
  • said accessory tool comprises at least two bodies to drag two continuous filaments coming from bobbins located on a creel on the machine frame, one of the system devices being capable of actuating the movement of both dragging bodies when a bobbin is not present in order to feed both filaments to two adjacent spinning positions.
  • said devices each comprise rotating cylinders arranged extending in parallel on the machine frame to actuate the motion of an accessory body or of a bobbin when the body or bobbin rests on these cylinders.
  • said cylinders have a rolling surface provided with grooves or ridges to facilitate gripping the non-elastomeric filament and again advantageously the cylinders are dimensioned to actuate the motion of a bobbin of more than 250 mm in diameter, such as for example, a bobbin of continuous filament of elastomultiester fibre T-400 ® Brand by INVISTA.
  • said system comprises a processing and control unit programmed to change the speed of the rotating cylinders of the devices depending on the type of continuous filament being unwound.
  • the processing and control unit programs itself to change the speed of the rotating cylinders depending on the type of filament, adapting it to the speed of the drafting system output roller to provide adequate drafting ratio.
  • said accessory dragging bodies are cylindrical bodies dimensioned to drag the continuous filament over the rotating cylinders by such rotating cylinders actuating the movement of said cylindrical bodies.
  • Each of the accessory cylindrical bodies drags the continuous filament from a spinning position over the cylinders allowing the filament coming from the creel to smoothly unwind with a suitable output tension.
  • the system comprises a bobbin support creel provided with a plurality of tubes to deliver the continuous filament coming from the bobbins to the device which actuates the movement of the accessory filament-dragging bodies.
  • creel is an overhead creel dimensioned to support bobbins of up to 290 mm in length, said creel including a plurality of individual tubes through which the filament of each of the bobbins runs from an inlet to an outlet.
  • each of these individual tubes is arranged in correspondence with the rotating cylinders of the device that actuates the accessory filament-dragging bodies when the bobbins are not present.
  • the system claimed has the advantage of greatly facilitating production operations related to the handling of continuous filament from the bobbins located in the creel. Indeed, the system claimed can instantaneously stop or interrupt the filament feeding in order to perform a replacement or repair, by simply raising the dragging bodies on the cylinders, preventing the filament from unthreading inside the creel tubes, or from momentarily accumulating. Moreover, this lifting support makes it possible to easily start up the bobbins one by one, when starting on a production lot.
  • each one of said supports comprises a grip handle which is configured as a guide for the unwinding filaments.
  • each of said supports is dimensioned to hold two cylindrical dragging bodies arranged adjacent on the rotary cylinders, while the same support grip handle acts as guide for the filaments unwound by both dragging bodies.

  • These rotating cylinders are dimensioned to actuate the motion of a bobbin of 180 mm in diameter, such as a bobbin of elastomer filament of elastane or spandex fibre, Lycra ® brand.
  • said system comprises separate sensors integrated in a single circuit to detect breakage of one of the filaments when the filaments are fed to the same drafting system of the machine, said sensors being arranged in a support of the machine frame located below the first means which continuously feed the elastomeric filament (elastane or spandex fibre, Lycra ® . Brand).

  • some independent sensors integrated in a single circuit control the feeding of continuous filaments that make up the core of the "Core Spun" yarn, since these filaments converge in a part that acts as a guide and is arranged in the same support on which the sensors are located. Furthermore, this support also has a part that acts as a guide for the roving fibre bundle.
  • the present invention provides a ring-spinning machine which spins "Core spun" yarn combining one, two or three continuous filaments with coating roving fibres, characterized by the fact that it incorporates the claimed feeding system.
