  • Patent number: 9040139
    Abstract: The present invention relates to a process for producing a base material for disks of disk rolls, in which the disk roll contains a rotating shaft and a plurality of the disks fitted on the rotating shaft by insertion whereby the outer peripheral surface of the disks serves as a conveying surface, in which the process contains molding a slurry raw material containing inorganic fibers, an inorganic filler having an aspect ratio of from 1 to 25 and an inorganic binder into a plate shape; and drying the molded plate.

  • Patent number: 4248991
    Abstract: An elastic strapping band is essentially made of ethylene-vinyl acetate copolymer containing vinyl acetate in the range of 3 to 20 wt %. The band has molecular orientation in the lengthwise direction thereof with a double refraction rate (.DELTA.n) being in the range of 24.times.10.sup.-3 to 38.times.10.sup.-3. The band has a tensile strength higher than 3.3 kg/mm.sup.2, a stress residual rate higher than 15% after elongating the band under an initial load of 3.3 kg/mm.sup.2, and an elasticity recovering rate higher than 70%.
