METHOD FOR MANUFACTURING A PREFORM MADE OF WOVEN REINFORCEMENT FIBERS HAVING A VARIABLE CROSS-SECTION
The present disclosure provides a method for manufacturing a preform made of reinforcement fibers woven in a longitudinal direction. The preform is impregnated with resin in order to form an elongated element having a variable transverse cross-section. In one form, the method includes the step of simultaneously including a reduction (or increase) in width and an increase (or reduction) in height. The variable cross-section includes, along the length thereof, a consistent number (c) of continuous warp threads arranged in layers. The method for reducing width includes carrying out a change in weave, adding additional weft threads, and simultaneously drawing the teeth of the longitudinal beater reed closer together so as to increase the number of layers.

Methods and systems for triggered on-loom fabric inspection
On-loom fabric inspection system (500) including an imaging device (522) configured to collect images of a weaving area (518) of a loom (502). An image-capture trigger-mechanism (529) triggers the imaging device (522) to capture images at required instants during the weaving cycle. An image processor (524) receives data from the imaging device (522) and further detects irregularities in the data.

Loom, method for producing textile, and ultrahigh-density textile
A loom capable of weaving an ultra-high density textile includes: multiple heddles which make some warps of multiple warps separated from other warps; a weft guiding portion making wefts pass through an opening; a reed pressing the wefts passing through the opening towards a fell so as to form a textile; a feeding roller which feeds the warps to the heddles at a position that deviates and staggers from an imaginary plane passing through the center of the moving range of the heddles and the fell; a delivery loom beam delivering the warps to the feeding roller; and a textile winding loom beam winding the textile, when the heddles is at the center, the tension of the warps being set as 0.32 cN/dTex or more and 0.38 cN/dTex or less.

PILE KNIT FABRIC FOR INTERIOR MATERIALS OF VEHICLES, METHOD OF MANUFACTURING THE SAME AND MANUFACTURING MACHINE OF PILE KNIT FABRIC
A pile knit fabric for internal materials of vehicles may include a knit layer prepared by weaving ground yarns, on one surface thereof, and a pile layer prepared by interweaving pile yarns with ground yarn loops of the knit layer, on the other surface thereof and, thus, has excellent physical coupling force between the ground yarns and the pile yarns and has excellent abrasion resistance, scratch resistance and formability as well as soft tactility.
