Disclosed are methods and devices for the formation of fabric preforms that may be subsequently impregnated with a resin to form a composite component. One end of the fabric is received on the form such that the axial tows of the fabric extend in a direction generally perpendicular to a central axis of the form. At least some of the plurality of axial tows are separately tensioned on an end of the fabric not attached to the form and the fabric is wrapped around the form by rotating the fabric and form relative to one another about the central axis.

An exemplary elongated elevator load bearing member of a traction elevator system includes a plurality of tension elements. A plurality of weave fibers transverse to the tension elements are woven with the tension elements. The weave fibers define at least one traction surface of the load bearing member.

Disclosed herein are a loom for weaving a fabric with two types of tissue, a shoe upper woven using the loom, and a shoe including such a shoe upper. The loom includes a first heddle stack formed by arranging a plurality of first heddles in one or more rows, and a second heddle stack formed by arranging a plurality of second heddles in one or more rows, the second heddles being different in kind from the first heddles. The first heddle stack and the second heddle stack are sequentially arranged in a warp feeding direction.

A method and apparatus for weaving a three-dimensional fabric involves inserting simultaneously a parallel weft yarns into the sheds between multiple warp yarn layers and selectively inserting at least one group of binder yarns between parallel spaced warp yarns. The group of binder yarns are moved relative to the warp yarns between weft insertions. The yarns may be moved between more than two positions relative to the warp yarns during weaving of the fabric so as to insert binder yarns. In one embodiment the binder yarns are moved such that they extend in a direction that is not orthogonal to the warp yarns.

A fiber structure for reinforcing a composite material part, the structure being woven as a single piece by multilayer weaving between a first plurality of layers of yarns extending in a first direction and a second plurality of layers of yarns extending in a second direction. The second plurality of layers of yarns includes at least one layer of variable-weight yarns, each variable-weight yarn including a separable assembly of individual yarns, each having a determined weight. The fiber structure includes at least one portion of reduced thickness in which the variable-weight yarn presents a weight that is less than the weight that it presents prior to the reduced thickness portion.

An airbag base fabric satisfying characteristics A to D: (A) the cross-sectional deformation (WR), calculated by formula (1), of multifilament warp threads constituting a textile is 4.0 to 6.0,

WR=(Major axis of warp thread cross section in textile)/(Minor axis of warp thread cross section in textile) (1) (B) the cross-sectional deformation (FR), calculated by formula (2), of multifilament weft threads constituting the textile is 2.4 to 4.0,

FR=(Major axis of weft thread cross section in textile)/(Minor axis of weft thread cross section in textile) (2) (C) the single fiber cross-sectional shape of the multifilament threads constituting the textile is substantially circular, and (D) the multifilament threads constituting the textile have total fineness of 145 to 720 dtex, single fiber fineness of 2 to 7 dtex, and tensile strength of 6.5 to 8.5 cN/dtex.

A medical balloon with a variable diameter that is reinforced with continuous fibers woven to form a fabric with a varying number of layers and fiber densities. Portions of the balloon having a relatively smaller diameter are reinforced with a fabric having a reduced fiber density and an increased number of layers to facilitate the placement of the layers. The fabric also includes a braiding pattern that facilitates the transition from a single layer fabric to a multiple layer fabric. Also described is a manufacturing method for the braiding and layering.

A heddle (10) is provided for weaving strip-shaped warp yarn. Said heddle (10) includes a heddle shaft (12) formed by two shaft parts (13). Said shaft parts (13) are placed on top of each other in a respective end section (15) of the heddle shaft (12) and interconnected. The end eyelets (16) of the heddle (10) are also in said end section (15). To form a yarn eye between both shaft parts (13), two separate warp yarn guiding bodies (20) are placed therebetween. To determine the position of the warp yarn guiding body (20) with respect to the heddle shaft (12), at least one shaft projection (22) is produced by stamping and subsequent bending or embossing each shaft part (13) for each warp yarn guiding body (20). Said shaft projection (22) engages in an associated recess (25) of the warp yarn guiding body (20), and a bonding connection is produced.
