  • Apparatus and method for laminated grinding disks employing vibration damping materials
    Patent number: 5092082
    Abstract: Laminated grinding disks are built up in layers with the interposition of at least one layer of vibration-damping materials as sound insulation, the layer of vibration-damping materials being placed in the mold in the form of fine, free-flowing powder and/or granules. The powder or granules can consist of elastomers which can withstand heating to more than 110.degree. C. The elastomer can be mixed with synthetic resin. The addition of filler improves the working qualities of the mixture and improves its granulability.
