Abstract:
Apparatus for measuring thickness of inserts as they move along a curved path comprising:a rotating cam having a curved cam surface extending from a low point to a high point about its circumference, said high point serving as a reading position; a sensor fixedly mounted at a given position; a pivot arm swingable about a fixedly mounted shaft; a portion of said pivot arm being positioned opposite said sensor and to one side of said shaft; a bearing mounted on said pivot arm on a side of said pivot arm opposite said shaft; said pivot arm normally biased by a spring toward a first position urging said bearing toward said cam for measuring a thickness of inserts passing between and engaging said bearing and said cam over a first thickness range, said sensor generating a signal representative of an angular position of said pivot arm, said sensor signal being read when said reading position is aligned with said bearing.
