Abstract (en)

[origin: DE19747637A1] The invention relates to an error device with ultrasonic signals for continuous plastic strips, profiles or tubes. Stationary measuring heads are arranged and spread out along the width of the strip or on the circumference of the tube. Said measuring heads inject ultrasonic signals into the plastic and pick up reflected signals. The number of evaluation-relevant signals is reduced by mathematical combination of subtraction and addition steps.
