A METHOD OF PROCESS TEMPERATURE MONITORING FOR DIELECTRIC HEAT-SEALING OF STRUCTURAL FABRICS

摘要

In dielectric heat-sealing of synthetic materials the peak temperature must be kept below some critical value, depending on the fiber composition, in order to prevent destructive overheating. Continuous seal temperature monitoring has not heretofore been possible, and trouble has been experienced with excess heat. By the use of temperature indicative coating, striped on the material, an objective and accurate seam quality assurance technique has been developed. It is described in detail and its advantages are discussed.
