ABSTRACT:
A guard includes a housing which is mounted on the movable ram of a press brake. The housing supports a pivotally and slideably mounted guard plate and a fluorescent light bulb. The guard plate is positioned in front of the male and female dies of the press brake and prevents accidental contact with the dies. When a work piece is inserted between the dies, the guard plate is pushed upward and the motion of the guard plate actuates a switch which turns the fluorescent light bulb on. When the workpiece is removed, the guard plate returns to the original position under the influence of gravity and the fluorescent light bulb is turned off.
