A weft detection sensor is provided that detects a passage of a weft to determine a passage timing of a weft circulating around a storage drum, and a weft insertion method includes setting in advance a reference value of a set position arrival timing in association with a set arrival position, regarding the set arrival position and the set position arrival timing at which a leading edge of the weft reaches the set arrival position, and determining an actual value of the set position arrival timing from the passage timing determined in weft insertion during weaving, comparing the actual value with the reference value, and in a case where a deviation occurs between the actual value and the reference value, determining a correction amount of a set value of a weft insertion related device based on the deviation so that the deviation decreases.

The present embodiments provide a woven element having a first plurality of warp threads extending in a first direction and integrated into a first surface on a front side of the woven element. The woven element may have a second plurality of warp threads extending in the first direction, where the second plurality of warp threads is integrated into a second surface on a back side of the woven element. A first weft thread may extend in a second direction, where a first portion of the first weft thread is positioned in front of at least one warp thread of the first plurality of warp threads to form at least a portion of a graphic image on the front surface. A second portion of the first weft thread may extend between the first plurality of warp threads and the second plurality of warp threads.

This method is for weaving a fabric with warp yarns and in-woven weft yarns (34) on a weaving loom which comprises, amongst others, a weft selector (28) and a weft insertion mechanism (20), for drawing-in a weft yarn from a pick-up position into the shed, along a weft insertion axis (Y20) and in a forward direction, the weft insertion mechanism including a gripper (40) openable at the pick-up position. This method includes at least the following steps: opening the gripper; positioning a movable carriage (102) of the weft selector so that the gripper (40) is aligned with a selected weft yarn (34); clamping the weft yarn in the selected distribution channel (130), with the clamp (164) of this channel; moving the weft yarn (34) along the selected distribution channel (130) toward the gripper (40), while the gripper is opened, by moving the clamp along the selected distribution channel; catching the selected weft yarn with the gripper at the pick-up position; drawing-in the weft yarn with the weft insertion mechanism, from the pick-up position into the shed, along the weft insertion axis and in the forward direction; and cutting the weft yarn. The weft selector defines several selectable distribution channels (130) parallel to the weft insertion axis (Y20), each selectable distribution channel including a forward guiding member (126), for guiding a weft yarn toward the gripper, and a clamp (164).

A method and a system disclosed include drawing each of multiple synthetic yarns from a corresponding supply package to form an oriented yarn. Filaments within the oriented yarn are twisted and detwisted to provide texture thereto, to provide a low stability interlacing during weaving, and to intermingle the filaments, and a uniform air pressure is applied to the oriented yarn to provide a counter-twist. Also, a multi-pick yarn package is formed based on winding all formed oriented yarns, which serve as weft yarns forming adjacent substantially parallel yarns wound together, onto a spool. These weft yarns are simultaneously inserted in a single pick insertion event of a loom apparatus, and conveyed across a warp shed of the loom apparatus through a set of warp yarns. The set of warp yarns and the conveyed weft yarns are interlaced to produce an incremental length of a woven textile fabric.
