<p>The anticorrosive treatement process for braided cables and drive system comprises, starting from a braided cable with a layer of residual zinc originating from the zinc deposition or galvanisation of the wire which has subsequently been drawn and braided although this layer remaining in the threads or filaments of the cable is very thin, without deposition of metal or organic or synthetic resin, etc. in order to obtain a final product having a high grade of resistance to corrosion without alteration of the mechanical behaviour. This process comprises the following steps: degreasing, dripping, washing, neutralisation, chromatization, dripping and washing, sealing, dripping and drying; the second washing can be eliminated and, in certain cases it can be proceeded subsequently to a last lubrication step. The drive system is based on independent variable and self-controllable motors, each connected to a reel at each step of the process. The system comprises for each motor an assembly consisting of an arm, a counterweight and an analog sensor for the speed regulation of the motor when the tension of the cable varies. <IMAGE></p> |
