  • Non-slip material
    Patent number: 7162839
    Abstract: The invention provides a slip stopper which achieves a great slip stopping effect, and can be used for a location where a problem occurs if a through hole is opened therein. In a protruding portion that protrudes from the upper surface of a steel plate in the plate thickness direction, a concave portion and drain channels, that lead to the steel plate upper surface from the concave portion, are formed. The inner surface of the concave portion and the groove side surfaces of drain channels are formed by shear planes which extend substantially perpendicular to the steel plate upper surface, and are obtained by half blanking that does not open a through hole in the steel plate.

  • Method and apparatus for manufacturing slip stopper
    Patent number: 7021109
    Abstract: An easy manufacturing method of a slip stopper, and apparatus therefor, that has a great slip stopping effect and can be used for a location where a problem occurs if a though hole is opened therein. After a protruding portion is formed on a steel plate, by using a first punching die unit, so as to protrude from the upper surface in a plate thickness direction, a concave portion and drain channels are formed in the protruding portion by shear planes that extend substantially perpendicular to the steel plate upper surface and have been half-blanked so as not to open a through hole in the steel plate by using a second punching die unit.

  • Method and device for manufacturing slip prevention material of construction machinery
    Publication number: 20040134251
    Abstract: The present invention achieves easy manufacturing of a slip stopper that has a great slip stopping effect and can be used for a location where a problem occurs if a though hole is opened therein. After a protruding portion is formed by using a first punching die unit so as to protrude from the upper surface of a steel plate 5 in a plate thickness direction, a concave portion 8 and drain channels 9 are formed in the protruding portion by shear planes that face almost perpendicularly to the steel plate upper surface and have been half-blanked so as not to open a through hole in the steel plate by using a second punching die unit 11, whereby it becomes possible to readily manufacture an excellent slip stopper.
