    摘要: A scoring board is manufactured by modifying standard blind rivets so that the headed shafts are removed, inverted, and trimmed to provide scoring pegs. The usual tubular sleeve of the blind rivet becomes an insert in enlarged holes in the body of the board. These freely receive the pegs to provide wear-proof receptacles for pegs that are enconomically manufactured by a process relating to nail forging.

    摘要: A roller unit for use as a caster for luggage, for example, has a sturdy -piece roller housing formed of sheet metal, the housing comprising a rectangular base with raised pads at opposite ends thereof and a roller-receiving shell defined by a pair of opposed U-shaped walls bent from opposite longitudinal edge regions of the base between the pads. Roller units are manufactured seriatim by metal forming operations that do not require deep-drawing.
