A wire inserting device, an elongated workpiece winding apparatus having the wire inserting device, and a wire inserting method are provided to insert a wire in a bundle of an elongated workpiece at an intermediate point in the bundle. The wire inserting device includes a detector arranged at a position corresponding to the intermediate point, and a wire holder configured to releasably hold the wire. The detector is configured to move when pushed by the elongated workpiece placed at the intermediate point during a formation of the bundle of the elongated workpiece. The wire holder is configured to move in synchronization with the detector to insert the wire in the bundle at the intermediate point.

An apparatus (1) and a method for coiling a cable (2) or a wire into a coil (3) having a plurality of turns (3a) and two free ends (4, 5) formed by a leading end (4) and a trailing end (5) of said cable are disclosed. The apparatus comprises a rotatable coil former (6) around which a cable is coiled; means (9) to measure the length of the coiled cable (2) or wire; first holding means (10) positioned on said coil former (6) for holding the leading end (4) of the cable, second holding means (12), separate from said coil former (6) for receiving and holding the leading end (4) of the cable (2), which are movable. Cutting means (14) for cutting the coiled cable to provide a trailing end (5) of the cable are also provided. The apparatus further comprises means (7) to adjust the diameter (D1, D2) of the coil former (6) and control means (18) to set said adjusting means (7) of the diameter of the coil former (6), to provide the required length of the cable and the required length of the said free ends (4, 5) of the coiled cable.

摘要:
The present invention relates to a process for manufacturing pieces of revolution made of three-dimensional material, of which the generatrix has at least one concave part, said process consisting in making a support mandrel provided with rows of pins defining therebetween longitudinal corridors and circumferential corridors, in disposing superposed layers of yarns in said corridors by winding and by filling, in densifying the assembly thus obtained, and, finally, in eliminating the support mandrel, wherein the longitudinal yarns are deposited in corresponding corridors and these yarns are maintained in the corridors at the level of said concave part. The invention also relates to a machine for carrying out this process.
