  • Publication number: 20120115701
    Abstract: A processing apparatus for a sheet member includes a mounting member where the sheet member is mounted, a rotating roller that rotates with a peripheral surface thereof opposing the mounting member, a processing component on the peripheral surface and movable on the peripheral surface along an axial direction of the rotating roller, and an adjustment mechanism that adjusts a relative position of the processing component with respect to the peripheral surface in the axial direction. The processing component is configured to process the sheet member by coming into contact with the sheet member with the rotating roller being rotated, while the sheet member is passing between the mounting member and the rotating roller with the sheet member being mounted on the mounting member. The adjustment mechanism is configured to adjust the relative position by moving the processing component on the peripheral surface along the axial direction.

    Abstract: A drawing apparatus to draw a sheet includes a first protrusion group aligned in rows along a drawing direction of the sheet; and a second protrusion group aligned in rows along the drawing direction and that meshes with the first protrusion group. The sheet is bitten in between the first and second protrusion groups. A space in which the sheet is bitten with the first protrusion group and the second protrusion group includes a first region, a second region adjacent to the first region, and a third region adjacent to the second region opposite to the first region. A drawing amount of the sheet in the case that the sheet is bitten with the first protrusion group and the second protrusion group in the second region is greater than the drawing amount in the first region and is smaller than the drawing amount in the third region.
