Abstract
A spacer plate construction for use in selective spacing between the head end and tail end of strips to be welded end-to-end by a welding machine. Sensors in the form of spring biased pivotal (or otherwise moveable) elements are mounted in longitudinally spaced cavities in the spacer plate to assure that the strip ends are held flush against the spacer plate before clamping for subsequent flash or butt welding. It is only when the sensor elements are moved inwardly to the sides of the spacer plate sufficiently to actuate a proximity switch mounted within the sensor plate that a circuit for initiating clamping of the head end and tail end of the strips can be initiated for subsequent welding.
