    摘要: Crimping machine for chemical-fiber filaments with crimping chamber having an oscillating upper plate loaded with a closure force for imparting a pressure on the tow which passes through the crimping chamber, wherein the plates of the crimping chamber are mounted on respective supports through two or more linear guides provided with a roller or ball recirculation system. The longitudinal operating position is determined by two pairs of hydraulic cylinders, having an axis parallel to the linear guides, which maintain the plates, or a portion thereof, pushed against respective fixed abutments without the use of further mechanical or oleodynamic blocking elements. Load cells are arranged between the abutments and the plates, for detecting the variations of the tightening force during machine operation, the variations, representative of the variable longitudinal force imparted by the filaments of the tow being processed on the plates, are used for monitoring the quality of the crimp obtained.

    摘要: Process for manufacturing carbon fibres, includes a first spinning step of a fibre of PAN precursor and a second oxidation/carbonization step of the fibre and the plant thereof. The spinning and oxidation/carbonization steps are performed directly in line and continuously, and hence without any stocking buffer area of a PAN precursor between the two steps. The spinning step is performed at low speed, so that the output speed from the spinning step, downstream of the stretching operations, is a speed falling within the range of the suitable processing speeds in the subsequent oxidation/carbonization step. Moreover, the spinning step is performed in a modular way on a plurality of spinning modules aligned in one or more rows, each spinning module having a productivity not above 10% of the overall productivity of the spinning step. In any individual spinning module, the fibres downstream of the spinning area follow zig-zag, rectilinear paths.

    摘要: In a crimping process in a crimping machine therefor, a compression force on an extended length of a transiting fiber bundle is exerted by and between means for maintaining a continuous and forced contact. The means for maintaining a continuous and forced contact comprise two closed belts, each of which runs around two motorized rollers travelling at a same velocity as the fiber bundle. Pressurized air or steam is injected into the crimping machine in a same direction as an advancement direction of the fiber bundles, but in an opposite sense thereto.
