摘要： A machine safety mechanism wherein the gate rotates in its own plane in about an axis extending transversely of the axis of movement of the movable die members, for example. In its ''''actuation-prevent'''' position, the gate is disposed at one end stop of a travel arc of 90*. In this position, the gate blocks access to the machine actuator console. In its ''''accessprevent'''' position, the gate has been rotated about its axis through its travel arc of 90* to an opposite end stop. In this position, the gate prevents access to an area between the closing machine parts, such as the die members, for example. The gate is constructed so the operator can see through it; i.e., in practice, it might be fabricated of heavy wire mesh in a frame or, in contrast, of a heavy plastic.
