The original 'finish' or the lubricating softener applied by the manufacturer to monofilament fishing line to modify its surface frictional properties can be replaced by the application to the line and/or the guide surfaces of the rod and reel of a small amount of an aqueous solution of a compound used heretofore to modify the frictional properties and hand of fibers prior to forming textiles, fabrics and carpeting therefrom.

Method for lubricating and conditioning monofilament fishing lines

Two or more single strands are formed and false twisted to provide sections of S-twist and Z-twist which are longitudinally spaced apart and separated by nodes which have no twist. The strands while moving longitudinally are held against rotation at points between which the adjacent strands twist in a same direction. The twist between each pair of points becomes redistributed, and the strands are released to enable them to twist together to form a self twist plural strand yarn. The strands are held against rotation during twist redistribution by apparatus which includes a device for interconnecting the strands at the points, and a rotation preventer which moves with and lies between the strands adjacent to the interconnected points.

Self-twisted yarn and method and apparatus for producing it

Groups of singles yarns are false-twisted, brought together node locked and plied to form plied strands. Additional torque in the plying direction is applied beyond the equilibrium point to add twist to the plied strands. Jet devices using air or steam can be used to apply the additional torque.

Self-twist yarn and method of making same

A stable plied yarn is produced by false-twisting two or more singles yarn strands with false-twist jets and passing the strands around a yarn wheel whereon the nodes are joined. The strands leave the wheel and ply together. The plied yarn is collected and can be tufted into carpet. The pressure of the fluid (air) supplied to the false-twist jets is varied to product varying amounts of twist in the singles strands which results in a range of twist amounts in the yarn plied therefrom, thereby avoiding streak effects in products made from the yarn.

Variable twist self-twist yarn

A temporary fabric is formed by joining groups of two or more yarn strands at a time together at various longitudinally spaced points, forming generally transverse lines of joined points across an array of a plurality of parallel strands. No weft or filler yarn is used. An apparatus for joining is disclosed including a drum having a plurality of abrasive rotating joining discs in the surface thereof. A second embodiment includes joining discs moved transversely across a plurality of longitudinally traveling strands. The fabric can be separated into individual strands by pulling the strands apart.

Method for forming temporary fabrics

Self-twisted yarn is packaged on a take-up device to prevent loss or modification of the twist previously imparted to the yarn by maintaining the yarn in a substantially rotation-free state as it is guided onto the take-up device. This is accomplished by wrapping the yarn around an elongated guide rod as it is fed to the take-up device under tension or by controlling the tensioned free length of the yarn as it is guided onto the take-up device to preclude rotation of the nodes or points of twist reversal in the yarn.

Packaging of self-twist yarns

Singles yarns are formed from a synthetic material, twisted in one direction, heat-set, cooled and false-twisted in the opposite direction. Two similarly treated strands are joined at their nodes and plied, resulting in an improved ply-twist singles twist ratio. The first twisting and heat-setting can be done concurrently using jet twisting with steam, and apparatus for accomplishing this is disclosed.

Method and apparatus for controlling twist in yarn

False-twisted yarn strands are separately carried around a guide wheel and the nodes thereof are brought together and locked by applying heat to the nodes and pressing them together, after which the strands are self-twisted. Embodiments include a cam actuated clamping device which holds the yarns in an ultrasonic transducer to which energy is supplied to accomplish the welding. Devices using resistance heating and laser impulses are also disclosed.

Yarn forming apparatus with node welding

False-twisted yarn strands are separately carried around a guide wheel and the nodes thereof are brought together and locked by mechanical entanglement, after which the strands are self-twisted. Embodiments of entanglement joining devices include reciprocating friction plates which rub the fibers together and twist them, causing joining, the plates being carried on the guide wheel. A needle punching device carried by the wheel is disclosed, the needles being reciprocated by a cam structure within the wheel. In a third embodiment edges of oppositely rotating overlapping discs contact and twist fibers in the node area, causing entanglement.

Yarn forming apparatus with mechanical node locking

False-twisted yarns are continuously fed to a locking mechanism on a rotating guide wheel. The locking device has a clamping shoe for engaging the yarn, after which the direction of false twist is reversed. Two additional clamping shoes then engage the yarn upstream and downstream of the first clamping point. The first shoe is then retracted to permit the twist between the additional shoes to cancel, and a fluid vortex is used to entangle the yarn filaments, locking the node.

Node fixation in self-twist yarn

Self-twist plural yarn strands are produced by a system wherein at least two singles yarn strands are individually twisted to form twisted strands each having longitudinally spaced nodes. The strands are separately conveyed around a yarn wheel and brought together in a parallel relationship with the nodes of one strand substantially aligned with the nodes of each other strand. The corresponding nodes from one strand are fastened to those of each other strand by heating with an electric arc and the strands are removed from the wheel and allowed to ply. The node fastening means comprises a pair of electrodes and a circuit for supplying arc-producing voltage across the electrodes. One electrode is mounted on the wheel and extends diagonally across and under the node location. The other electrode is fixed adjacent the wheel so that the arc traverses the yarn as it passes from one end of the diagonal electrode to the other.

Self-twist yarn node fixation apparatus and method

Self-twist plural yarn strands are produced by a system wherein at least two singles yarn strands are individually twisted to form twisted strands each having longitudinally spaced nodes, and strands are brought together in a parallel relationship with the nodes of one strand substantially aligned with the nodes of each other strand. The corresponding nodes from one strand are fastened to those of each other strand, and the strands are allowed to ply. The node fastening means comprises a rotating member having a contact surface for fastening the nodes by gathering and twisting of the fibers from one strand with those of another strand at the nodes of each respective strand. Ply yarn twist uniformity is assured through the use of improved twist insertion jets, together with a means for holding singles yarns separate to allow longitudinal levelling of singles yarn torque prior to plying.

Self twist yarn strand and method

A stable plied yarn is produced by false-twisting two or more singles yarn strands with jets and passing the strands around a yarn wheel whereon the nodes are joined. The strands leave the wheel and ply together. The plied yarn passes through a reversible jet aspirator which assists the plying and propels the yarn through a coiled tube. The aspirator is supplied with air or with steam to bulk the yarn. After leaving the tube, the yarn can be caused to strike a solid surface to further enhance bulking. A press roll at the yarn wheel aids in defining a twist trap.

Fluid self-twist spinning apparatus

A dielectric heat generator in which radio frequency energy derived from a radio frequency oscillator is divided into two separate ratio frequency components which are equal but out of phase with each other. Each component is applied to a separate electrode. In one embodiment the two components are essentially 180.degree. out of phase and each component is applied to a different one of two electrodes that are positioned in tandem and facing a third electrode which is coupled to ground. In a second embodiment, the components are essentially 180.degree. out of phase and each component is applied to a different one of two electrodes that are facing each other and spaced apart from each other. In a third embodiment, the two components are essentially 90.degree. out of phase and are applied to an arrangement of finger electrodes.

Dielectric heat generator

A weave-de-weave process in which a plurality of weft loops are fluidly injected from opposite sides and normal to a plurality of warp yarns to form a composite tape. The tape is deweaved after the warp is space dyed by splitting the interior of the tape to expose the looped ends of the weft.
