ABSTRACT:
A method and apparatus which dynamically determines the location of a fabric layer bonded within a moving calender strip of elastomeric material by passing opposed surfaces of the strip partially about a respective one of a pair of measuring rolls forming a part of a two pair over-under rolls. Sensors are connected to each of the measuring rolls and provide a signal in relationship to the rotational speed of each of the measuring rolls. The two signals are compared and provide a third signal indicating the relative position or balance of the fabric layer with respect to the two outer strip surfaces. Since the fabric layer when under the same dynamic tension and conditions will achieve a specific elongation its radial position with respect to the surfaces of the measuring rolls will control the rotational speed of the rolls when contacted by the moving surfaces of the calender strip. The radial relationship of the fabric layer within the strip will effect the speeds of the two measuring rolls as they are rotated by contact with the opposite surfaces of the strip. Each of the measuring rolls may have a plurality of freely rotating axially aligned roll sections which provide individual signals for specific transverse zones of the strip to determine the location of the fabric layer in the transverse direction across the moving strip as well as in the linear direction thereof.
