Abstract
An automatic shoe bottom roughing machine has tool supports mounted on movable carrier arms to permit movement of the arms widthwise across the shoe bottom, the tool support being pivotable heightwise, both the tool supports and the arms being light in weight to reduce unnecessary movement or bounce in the tools, the machine including a one-way hydraulic damping arrangement effective to resist upward movement of the tools.
