ABSTRACT:
The device and related process for the manufacture of vibration-damping and shockproof mountings formed of metal cable spirals comprise a generator of low speed rotational motion; a spindle formed of at least two portions, parallel longitudinally developing and adjustably matchable to each other, having outer surfaces corresponding to those of the cable spirals to be formed, and at least two planar zones along two diametrically opposite generatrices, each of such zones for the bearing thereon of one of the terminal forming bars connecting with the bar, the pairs of bars having the matching surfaces provided with semicylindrical connecting seats for accommodating and firmly tightening for a short length the cable spirals, but without any distortion to the elementary wires thereof; a braking system for holding the in-coming cable under tension, slidable on two parallel shafts, to supply the spiral winding on the spindle body; a clamp for securing the cable to be wound up at the operation start and a spacer downstream of the formed spirals on the spindle, the loosening of which allows the finished vibration-damping and shockproof mounting to be released. The present device and process are used for mechanically manufacturing vibration-damping and shockproof mountings particularly employed for the protection of delicate equipments subjected to very high shocks and vibrations during operation.
