PROCESS FOR MAKING A MULTIDIRECTIONAL TEXTILE PREFORM, DEVICE THEREFOR AND RESULTING PREFORM

摘要

the object of the invention is a process for making a preformmultidirectional textile, which is deposited on a substrate, capable ofa first layer section (m) sections of wire, and, if necessary, aand several other water from different directions, so thatto achieve a sequence of files, then, perhaps aa number of other sequences of removal of plates, each section of the thread (3).3, 2, 3) are fixed at each end, the stitching without knottingthe substrate (w) with a needle (11), (12), characterized in that thestitchingthe two ends of each segment (3, 1, 3, 3, 3) is implemented as awith the help of two independent pins (11, 12), using a separate thread(p 1, p 2) of the ground, the end of the section of wire is inthe arrivalthe head of a height of a turning point, as determined by the threadsewing needle sewing, as the "keycouplingduring removal of the string section of the needle is thrust into theless than the deflection of the needle stitching at the other endthethe following section.application to the realization of composite parts
