  • Publication number: 20230339060
    Abstract: In a processing machine 1, an X-axis control unit 33X, in each control cycle Tc, controls the position of an X-axis table 9X in the X-direction by feedback. The Z-axis control unit 33Z, in each control cycle Tc, acquires an up-close detection value of the position of the Z-axis table 9Z in the Z-direction, computes a second deviation based on a difference between the acquired detection value and a target position, and controls a Z-axis drive source 23z so that the second deviation is reduced. The Z-axis control unit 33Z, in each control cycle Tc, acquires an up-close detection value of a first error comprised of a deviation of the X-axis table 9 in the Z-direction, and increases or reduces the second deviation based on the detection value of the first error so that at least a portion of an error in a relative position of a workpiece 103 and a tool 101 in the Z-direction originating from the first error is cancelled by movement of the Z-axis table 9Z in the Z-direction.

  • Patent number: 11781254
    Abstract: A production method for a low molecular weight polymer suitable for a melt-blown non-woven fabric and a production device for melt-blown non-woven fabric, with which a high molecular weight polymer can be reduced in molecular weight by applying a shear force to the high molecular weight polymer without adding an additive. The low molecular weight polymer and the melt-blown non-woven fabric are produced using a continuous high shearing device that applies a shear force to the high molecular weight polymer serving as a raw material by rotation of a screw body to reduce the molecular weight of the high molecular weight polymer so as to obtain a low molecular weight polymer, and cools the low molecular weight polymer by passing the low molecular weight polymer through a passage arranged in the axial direction inside the screw body.
