Embodiment Construction

[0021] as attached figure 1 Shown schematically is a prior art knitting machine.

[0022] From left to right in the drawing, the knitting machine includes a covered yarn supply system 1 and a covered yarn sorting system 2. The covered yarn sorting system 2 includes a heald bearing hole 3, and the heddle is movably installed on the frame Placed one by one inside and driven vertically, it also includes a beating reed 9 and a weft yarn insertion system 10, such as a shuttle type weft yarn insertion system. The fabric is a braid 13 driven by a feed system 14 which applies a controllable tension to the covering yarn 8 which enters from the supply system 1 and exits from the feed system 14 .

[0023] Said beating reeds 9 extend between the covered yarns at the frame exit of the ordering system 2 and the teeth of each beating reed are used to push the weft yarn 10 against the fabric which moves back and forth 11 in reciprocating , 12 weaves.

[0024] Synchronized with the movement...

Abstract

The weaving loom of the invention is of the kind comprising a warp thread supply system (1), a frame type warp thread sequencing system (2), a reed (9) and a weft thread insertion system (10). The sequencing system (2, 25, 40) comprises means for driving side-by-side frames (27, 28; 41‑43). Application to the production of woven preforms in a single piece for a composite component, notably for aeronautical engineering.

Description

technical field [0001] The invention relates to a weaving machine with juxtaposed frames, a weaving method using the weaving machine and a preform formed by weaving thereby. Background technique [0002] In particular, the invention has application in the manufacture of composite parts in aeronautical engineering, using polymeric resins to form at least one fabric preform, which parts can be used in particular to realize the nacelle of a turbojet engine. [0003] The object of the invention is to produce textile preforms for obtaining composite parts such as sheets, beams and profiles such as guide or carrying rails. In this product, it is desirable to have different weaves in the weft direction. Thus, it is known to obtain a plurality of drapes, each drape as a defined weave, which are subsequently assembled by different weaving methods, such as stitching or lamination, before casting the resin, so that Assemble the pleats side by side. [0004] However, this is a comple...
