The device comprises, a knockout plate (14) having at least one vertical orifice (14a) therein for the passage of punch means (13) of the press-machine therethrough. The punch means and knockout plate are movable relative to each other by means of a cylinder and piston arrangement (19, 20, 22). A knockout actuation plunger head (23) is reciprocably movable along its central axis and is actuated by said piston which is disposed at a position eccentric to the plunger head.</p> |
