ABSTRACT:
An apparatus and method are provided for detecting a formation or change in the consistency of a moving sheet material. The apparatus includes a radiation source, a radiation receiver, a support base for the sheet material, and a signal processor for producing a signal in response to the detection of a formation in the material. The apparatus may be modified to include moving or stationary support bases, and may be further modified to include structure for automatically positioning the source and receiver to optimize the detection of formations.
