ABSTRACT:
An apparatus and method for a precision alignment of parallel fixed and movable platens of a machine, including a laser emitter for transmitting a narrow collimated laser beam having a control surface which is orthogonal to an axis of the laser emitter; a target for receiving the laser beam and producing an output voltage which is proportional to the displacement of the laser beam from the center of the target, and a pair of adapters for rotatably mounting the laser emitter on a fixed platen and the target on a movable platen of a machine. The adapters have control surfaces which are precisely orthogonal to axes of rotation of the emitter and target and a stud for tightly pulling together the orthogonal control surfaces of the emitter and target against the control surfaces of the adapters. Voltages from the target are processed in an electronic console and displayed on a display unit in alphanumeric form.
