WARPING DEVICE USING RETROREFLECTIVE YARN AND METHOD FOR WEAVING RAW FABRIC USING SAME
The present invention relates to a warping device using a retroreflective yarn and a method for weaving a raw fabric using the same and, more particularly, to a warping device using a retroreflective yarn and a method for weaving a raw fabric using the same, wherein a retroreflective yarn is applied as a warp such that a twisting phenomenon is prevented during weaving, thereby making it possible to acquire a raw fabric with excellent quality. The present invention, described above, provides, as the technical gist, a warping device using a retroreflective yarn and a method for weaving a raw fabric using the same, the warping device comprising: a creel unit having multiple bobbins, around which a yarn is wound, cradled thereon such that the yarn is unwound; an aligning unit for aligning the yarn, which has been unwound from the creel unit, at a predetermined interval; and a winding unit for winding the yarn, which has been aligned by the aligning unit, around a beam, wherein the creel unit comprises a main frame comprising horizontal bars, which are installed vertically at a predetermined interval, and vertical bars, which are installed between the horizontal bars at a predetermined interval, and a cradling frame comprising first cradling bars, which are formed to protrude from the inner side of respective vertical bars, and second cradling bars, which are formed to protrude from the outer side of respective vertical bars; first bobbins, around which a synthetic fiber yarn is wound, are cradled on respective first cradling bars; and second bobbins, around which a retroreflective yarn is wound, are cradled on respective second cradling bars to be perpendicular to the first bobbins.

SYSTEM FOR HANDLING AND PROCESSING YARN
An apparatus for servicing a twisting machine. The apparatus includes an automated guided vehicle (AGV), a robotic arm having an end effector coupled to the AGV, and a rack carried by the AGV. The rack is configured to hold a plurality of empty tubes and a plurality of yarn packages. A controller that is configured to cause the robotic arm to grip, by the end effector, a handle of a row of the twisting machine, lower a receptacle of the twisting machine to a loading position, remove an empty tube from a first receptacle of the at least one receptacle, place the empty tube on the rack, lift a yarn package from the rack, place the yarn package on the first receptacle, grip the handle of the row of the plurality of rows of the twisting machine, and raise the at least one receptacle to the operational position.
Yarn feed assembly to relieve yarn hang ups having a variable yarn pull-off angle and method of using same
A yarn feed assembly for directing yarn from a wound yarn source to a yarn feed tube having a frame member positioned adjacent to the wound yarn source and defining at least one elongate interior chamber. The yarn feed assembly has a weighted member slideably received in the elongate interior chamber such that, upon pulling one yarn off of the wound yarn source, through a bore of the weighted member and into the yarn feed tube, the weighted member is axially movable along a longitudinal axis of the frame member such that the bore of the weighted member is axially movable about and between a bottom end and a top end of the elongate slot in response to tension applied to the yarn as a result of yarn hang ups on the wound yarn source.
