  • Speed controller for the rolling cylindrical articles
    Patent number: 4243132
    Abstract: In an apparatus in which cylindrical articles violently collide with one another as they roll down on the inclined skid rails, from the inlet to the outlet thereof, a control rail covered thick with a soft and elastic foamed substance is located. The control rail is positioned side by side in parallel to the skid rails, and frequently reciprocated vertically to brake the articles as they move downwards over the skid rails so that the maximum rolling speed is sufficiently reduced for restricting the noise of collision below an allowable level.
