A method is provided for operating a textile machine having a plurality of identical workstations wherein, during a normal operation of the workstations, yarn is produced or rewound from a supply bobbin onto a receiving bobbin at the workstations. After a stoppage at a plurality of the work stations, the method includes starting and setting the plurality of workstation into a normal operating mode. The method includes dividing the plurality of workstations into groups of workstations, and starting up the groups of workstations at different predefined times, such as predefined waiting times between consecutive groups of the work stations.

The present invention is an automatic cut and transfer coiler and spooler apparatus, system and method for use generally comprising a rotatable turret with two independently driven spindles thereon wherein the drives for the independent spindles are attached to the turret for selectively rotating the spindles about their own axis independently.

An apparatus for the dispensing and retraction of wire or cable. The apparatus including a first and second plate, at least one shaft attached to the first plate and the second plate, a spool gear attached to the shaft, a power gear shaft attached to the first or second plate, and a power gear attached to the power gear shaft and in mesh with the spool gear, wherein when the power gear is rotated, the spool gear is rotated.

The apparatus and methods disclosed herein are directed to detecting the presence of a whipping tail when using a fiber winding system to wind a fiber onto a rotating spool. The fiber is guided onto the rotating spool through a containment region between the spool and a whip shield to create the wound fiber. The whipping tail outwardly extends from the wound fiber and periodically or quasi-periodically passes through a light beam to create a series intensity dips in the light beam, thereby forming a modulated light beam. The modulated light beam is converted into a digital electrical signal made up of electrical pulses having a timing defined by the intensity dips. The measured timing of the electrical pulses is compared to an estimated timing based on the rotating spool to ascertain the presence of a whipping tail.

The present disclosure provides composite yarn, apparatus and methods preparing thereof. The composite yarn of the present disclosure includes wrapping fibers and a central yarn that is formed by a first body yarn and a second body yarn, wherein a portion of the wrapping fibers are combined with the central yarn in at least one of the following states: a first state, a portion of the wrapping fibers wrap around the first body yarn or the second body yarn; a second state, a portion of the wrapping fibers wrap around the first body yarn and the second body yarn respectively at the same time; a third state, a portion of the wrapping fibers wrap around the central yarn. The composite yarn of the present disclosure has low twist factor and high strength, which solves the problem of severe strength loss associated with low twist factors existing in conventional low-twist techniques.

The invention relates to a winding device (16) for winding a yarn (20) onto a package tube (22) in order to form a yarn winding package (24). The winding device comprises a spindle (34) for holding and rotationally driving the package tube (22) about its longitudinal axis (30) and a support roller (40) that abuts against the peripheral surface of the yarn winding package (24) during winding of the yarn (20). The spindle (34) with the yarn winding package (24) can be swiveled relative to the support roller (40) by means of at least one pivotably mounted swivel arm (46). The winding device has a contact-force control device (54) with an actuator (56) for the swivel arm (46), with a control device (58) for controlling the actuator (56), and with a bending beam load cell (60) associated with the swivel arm (46). This is used to determine a respective actual value of the contact force F.sub.A of the yarn winding package (24) against the support roller (40) with which the contact force F.sub.A can be regulated to a predetermined target value by means of the control device (58) through appropriate controlling of the actuator (58). The invention further relates to a yarn processing machine (10) with an aforementioned winding device (16).
