摘要： In a method and apparatus for detecting ply defects in a pneumatic tire, measurements on the tire are obtained at two levels of tire inflation, and the data obtained in the two measurements are compared. Broken reinforcement cords in the tire cause changes in the peaks of the data obtained at the two inflations that are out of proportion when compared to data changes observed in non-damaged tires. The apparatus of the invention provides means for inflating tires to predetermined pressures and has displacement sensors for measuring peaks and valleys in the sidewall of a tire. The apparatus may also include a computer for collecting data, analyzing data, and providing a signal when a defective tire is recognized.

摘要： An apparatus which uses a sensing device for measuring gauges of elastomeric or rigid articles, or runout of elastomeric articles, has a pivoting arm which holds a means for creating a signal, and is movable relative to the object being measured. The means for creating a signal provides a signal to the sensing device, and the magnitude of the signal depends on the position of the pivoting arm relative to the object being measured. Movement of the pivoting arm, caused by changes in the dimensions of the object, can be recorded and analyzed.
