THREE-DIMENSIONAL KNITTED SECTIONS OF REINFORCED MATERIALS, AND PROCESS FOR MANUFACTURING THEM |
摘要 |
This section element has a cross-sectional shape with reentrant or inside angles and/or concave parts or a hollow polygonal or other shape. A plurality of parallel threads are held taut and maintained in the longitudinal direction of the section element in a configuration which corresponds to the cross-sectional shape of the desired section element. These longitudinal threads are progressively displaced continuously in front of a group of knitting heads knitting in two dimensions which are orthogonal and perpendicular to said longitudinal threads. Each knitting head comprises a plurality of series of needles I, L1, L2, LA, A1 and A1' each of which covers a specific portion of the cross section of the section element. |
