Methods And Devices For Transporting Yarn
A system can comprise a plurality of containers that are coupled together as a movable unit. A plurality of container-feeding assemblies can be configured to simultaneously deliver respective yarns into respective containers of the plurality of containers. A header can be selectively attachable to a tufting machine, the header having a longitudinal axis. A retainer can be configured to extend across the header along the longitudinal axis to secure the respective yarns in respective positions relative to each other along the longitudinal axis.
FIBER BUNDLE WINDING DEVICE
A fiber bundle winding device includes: a traverse guide configured to guide a fiber bundle to a bobbin; and a controller configured to control the traverse guide according to a rotation of the bobbin. The traverse guide is movable parallel to a center axis of the bobbin. The controller can perform: first movement control that moves the traverse guide to wind the fiber bundle onto the bobbin in a predetermined first area extending in a direction of the center axis of the bobbin; and second movement control that moves the traverse guide to wind the fiber bundle onto the bobbin in a second area being smaller than the first area and having ends that are located within the first area and at different positions from respective ends of the first area. The first movement control and second movement control are performed at a ratio of N:1 (N is an integer more than 1).
Yarn tension and breakage sensor system
A yarn monitoring system for textile machine uses sensors to indicate yarn over tensioning and breakage. The sensors are contained within, or adjacent to, eyelets and monitor, sending signals to the controller, the speed of the yarn. The eyelets, each with a sensor, are within a body that also contains a circuit board which is in constant communication with the eyelets and software contained within a controller. The controller, in turn, is in constant communication with the textile machine. The software is preprogrammed by a user with an acceptable signal range for passage of the yarn past the sensors and a predetermined time period for the signal to remain outside the acceptable signal range. To prevent unnecessary shut down of the textile machine, the software averages the signal and, when the averaged signal remains out of the acceptable signal range for the preprogrammed time initiates communication to the textile machine.
Yarn feeder with rotary storage drum and yarn-unwinding sensor
A motorized rotary drum supported on a motor housing bears a plurality of yarn loops wound thereon, such loops being adapted to be unwound upon request from a downstream machine. A yarn-unwinding sensor comprises light-emitting elements and light-receiving elements both of which are integral with the motor housing. Light-guiding elements which are integral with the drum guide the light from the light-emitting elements to a window which is defined on the rotary drum in a position such that it is repeatedly engaged by the yarn during its rotary unwinding motion, and vice versa. A reflecting surface reflects the light coming out of the window back towards the window. Light-deviating elements which are integral with the motor housing deviate the light coming back from the window towards the light-receiving elements. The unwinding of a yarn loop from the drum is determined on the basis of the variation of light resulting from the yarn transiting on the window.
Seamless filling woven tape unit, yarn tank transportation equipment and filling process thereof
A seamless filling woven tape unit, a yarn tank transportation equipment and the filling process thereof. The woven tape unit utilizes a woven tape and a filler arranged in the woven tape, wherein the woven tape utilizes several woven tape units formed by integrated weaving, the woven tape unit utilizes a hollow woven tape and a solid woven tape formed by integrally weaving the two ends of the hollow tape, and a cavity of the hollow woven tape is uniformly filled with a flexible filler injected through fiber injection equipment. The flexible filler is injected into the woven tapes by fiber injection equipment so elasticity of the woven tape is guaranteed. Since the flexible filler is directly injected into the cavity of the hollow woven tape through a pin-shaped thin pipe arranged on the fiber injection equipment, the woven tapes do not need to be sewn.
POLYAMIDE MONOFILAMENT AND FIBER PACKAGE THEREOF
A polyamide monofilament is characterized in that the abrasion tension thereof when passed through a ceramic guide is 0.3 cN/dtex or less and in that the amount of static electricity generated at the exit of a chromium round bar guide, which is a frictional body, when the polyamide monofilament is passed through the chromium round bar guide, is 300 V or less. This polyamide monofilament and fiber package provide a gauze woven fabric for which tension is low when passing through a thread path guide when warping warp yarn, for which generation of static electricity is suppressed, and which has excellent weaving productivity.
Winding machine
A take-up winding machine continuously coils a plurality of threads. The take-up winding machine has a plurality of rotatably mounted winding turrets which, in each case, support two protruding winding spindles and which are held beside one another in a machine frame so as to be spaced apart by a pitch. The take-up winding machine further has a plurality of traversing units and a plurality of contact rollers which together with the winding turrets form a plurality of coiling positions. The winding turrets are assigned one common turret drive. The winding turrets are configured so as to be drivable in the same direction. The contact rollers and the traversing units are held on the machine frame along one machine longitudinal side so as to be symmetrical to the pitch of the winding turrets.
