A yarn false twisting apparatus is disclosed which comprises a support bracket which mounts a pair of twist imparting circular discs, and drive means including a whorl rotatably mounted to the support bracket so as to be tangentially contacted by a drive belt mounted to the central frame of a twisting machine. The support bracket is mounted to the central frame for pivotal movement through 180 degrees to thereby permit selective operation in a first position wherein S twist is imparted to the yarn, and a second position wherein Z twist is imparted to the yarn. Preferably, one of the discs is composed of a thin flexible material, and a pressure applying member is mounted on the support bracket for biasing the flexible disc toward the other disc locally at the twisting zone. In the disclosed embodiment, the discs are also adjustably movable with respect to each other, and the pressure applying member is movable in a direction perpendicular to the movement of the discs, such that the ratio of twist insertion to yarn advance speed may be varied.

Friction false twisting apparatus

A multi-spindle double twist twisting machine having a belt drive assembly, a spindle frame formed to enclose the belt drive assembly, and traversing rod reciprocating means. The machine may be a horizontal spindle machine with two rows of spindles on each side. A beam mounted independently of the spindle frame extends along each side between rows and supports a drive belt for tangential driving contact with spindle whorls. The belts are commonly driven and reversing rolls are associated with one belt so that it travels opposite the other belt, and compensating rolls are associated with the other belt so that the belts may be of the same length. The spindle frame has two spaced support plates laterally outward of the belt drive assemblies and two cover plates secured to and extending between flanges on the support plates to form an enclosure for the belt drive assembly. The traversing rod reciprocating means uses a pulley and drive belt take-off from the drive shaft of one traversing rod reciprocating cam to drive a second cam so that only one drive motor, replaceable gear assembly and modulating gear assembly are required.

Multi-spindle double twist twisting machine

A process and apparatus for conveying a plurality of parallel individual strands into a composite strand, each individual strand being conducted between a delivery means and a draw-off means in common to all strands, all of the individual strands as well as the composite strand having adjustable speeds, wherein means are provided for measuring, comparing and controlling the speeds and tensional forces in the individual strands and in the composite strand to ensure a high quality plied or composite strand.

Process and apparatus for conveying individual strands into a composite

A two-for-one twisting process for twisting two or more individual strands being taken off from separate feed spools or packages arranged in sequence along a common twisting axis at spaced intervals, the strands being doubled or plied together along the twisting axis in a forward take-off direction, wherein the completely plied strands passing the final feed package are deflected and returned backwardly in a rotating balloon pattern by means of at least one rotating twisting disc such that a single balloon envelops each feed package with the plied strands crossing and finally meeting the twisting axis behind each package. The process is useful for plying and twisting all types of filamentary or stranded materials.

Two-for-one twisting process

A high-speed wire twisting machine with feed spools in cradle-type carriers rockingly mounted between paired rotors which have hollow axial passages and are aligned at spaced intervals on the twisting axis, each spool carrier being provided with deflection means to guide the wires, as they are initially drawn off and plied through the axis of the rotors in a forward direction, around each cradled feed spool, and the last rotor at the front end of the machine being provided with a guide over which the plied wires are drawn off and deflected outwardly to be returned to a rear outlet end of the machine, especially with a two-for-one twisting with the plied wires forming individual balloons between each pair of rotors. Twist stop means are preferably mounted in the front carrier which contains a feed spool or for special purposes a wire treatment means in place of the feed spool.

High speed twisting machine

A false twist crimping apparatus having an elongated contact heater with pivotable yarn guides in operating positions at either end of the heater, one yarn guide being shiftable lengthwise of the heater on a carrier means, said apparatus also including a pivotable rocker cam engaging the shiftable yarn guide when in its operating position for the transfer of pivot movements from the cam to the guide and linking means to connect the rocker cam with the other yarn guide to synchronize the pivot movements of the cam and both yarn guides, thereby applying the yarn onto or removing the yarn from the contact heater.
