Abstract: A process for attaching a functional flexible element on a flexible support without the use of adhesive composition. The process comprises a step of depositing a functional flexible element on a flexible support, a step of stitching along a zigzag line of at least one binding yarn on either side of the functional flexible element along the functional flexible element while retaining the functional flexible element on the flexible support. The first binding yarn(s) are stitched into the flexible support at stitching points to a depth of less than the thickness of the flexible support.

Abstract: A method of manufacturing a plurality of reinforcing element preforms, involving the steps of: positioning reinforcing elements on the external surface of a die; assembling the reinforcing elements thus positioned with one another so as to form a textile sleeve with a longitudinal axis and surrounding the die; moving the sleeve longitudinally toward a multi-cavity mandrel having an elongate overall shape, the multi-cavity mandrel having on its external surface a plurality of longitudinal cavities which are distributed, when viewed in cross section, around the periphery of the external surface; forming the sleeve on the plurality of peripheral cavities so that the sleeve conforms to the shape of the multi-cavity mandrel and thus adopts the shape of a set of reinforcing element preforms.

Abstract: Tire (10) comprises a knit (44) comprising: columns of loops, the loops of one and the same column being arranged one after the other substantially in an overall direction referred to as the main direction and rows of said loops, the loops of one and the same row being arranged one beside the other substantially in an overall direction referred to as the transverse direction. The knit (44) comprises first and second zones (451, 452), each respectively having, at least in one of the main or transverse directions, a force FT100 and FS100 at 100% elongation that satisfies FS100<FT100, each force FT100 and FS100 being determined from a force-elongation curve obtained by applying standard ISO 13934-1:2013 to the knit before it is incorporated into the tire (10).

Abstract: The tire (10) comprises at least one set (45) of at least two layers of at least one knit (441, 442), the two layers being at least partially superposed on one another. The knit (441, 442) comprises: columns of loops arranged one after the other substantially in an overall direction (X1) referred to as the main direction, rows of loops arranged one beside the other substantially in an overall direction (Z1) referred to as the transverse direction. The knit (441, 442) has a force at 100% elongation less than or equal to 40 N·row?1 and/or 40 N·column?1, the force at 100% elongation being determined from a force-elongation curve obtained by applying standard ISO 13934-1:2013 to the or each knit (441, 442) embedded in the standard elastomer matrix and the number of rows and/or columns being measured in accordance with standard NF EN 14971.

Abstract: The weaving loom of the present disclosure includes a warp thread supply system, a frame type warp thread sequencing system, a reed and a weft thread insertion system. The present disclosure also provides a weaving method using the weaving loom. The method includes: a step of designing a flat fabric which are multilayered and presenting several adjacent sections in a weft direction whose weave and layout are different; a step of designing a set of side-by-side frames for enabling a weaving of the adjacent sections in a continuity of a weft according to designed weaves and layouts; and a step of carrying out the weaving.

Abstract: A weaving process for direct manufacture of three-dimensional structures with bidimensional walls with corners, without the need for sewing or other assembly between two ridges. The weaving is made by transforming weft threads into warp threads for making at least one face. The process is particularly adapted for the weaving of reinforcing elements for composite structures of corner fitting type.

Abstract: A fiber structure that can be embedded in a matrix for obtaining a piece made of composite material, includes a first fiber element having a first support surface, at least one L-shaped fiber element having a base that is flattened against the support surface of the first fiber element at a junction zone and a wing that is not flattened against the first fiber element, and another fiber element having one part flattened against the wing of the at least one L-shaped fiber element. The elements are assembled by tapping fibers from a second surface of the first fiber element so as to form loops, at least certain fibers being oblique relative to the second surface, in a plane that is perpendicular to the junction zone, wherein certain loops of the oblique fibers protrude to the outside of the outer surface of a wing of at least one L-shaped fiber element.

Abstract: A weaving method that makes it possible to directly produce three-dimensional structures having two-dimensional walls with corners, without requiring sewing or other joining between two edges. The weave is created by turning weft threads (24) into warp threads to create at least one face. The method is particularly suitable for weaving reinforcing pieces for composite structures such as three-dimensional corner reinforcements.

Abstract: A weaving loom including a mechanism drawing-in threads, for insertion of picks, and for formation of a weaving shed, so as to render possible formation of a continuous angle or corner by a thread during weaving. The loom preferably also includes a vertical offset system, so that it is possible to weave a three-dimensional surfacic structure, the threads of which are continuous between the faces and at the level of the edges. The loom can be configured particularly for manufacture of continuous tridedral corners that are used as reinforcements for composite structures.
