  • Tire cord thermal analysis testing device and method
    Patent number: 4998825
    Abstract: Dimensional change in a tire cord (13) under thermomechanical stress is determined by a device (10) including an oven (12) for receiving and controlling the temperature of a preselected length of the cord (13), grips (14,15) for holding and selectively positioning the entire preselected length of cord (13) within the oven (12), and means (16) including an angular displacement transducer (51) for measuring changes in the preselected length of cord (13). Means (16) may also include weights (52,53) for the selective application of mechanical stress to the material. The steps employed in determining such dimensional change include inserting a length of cord (13) into grips (14,15), positioning the entire length of cord (13) (including the portion of grips (14,15) holding the cord (13)) within oven (12), controlling the temperature of the cord (13) in the oven (12), and measuring changes in the length of cord (13).
