Abstract (en)

[origin: WO9635109A1] A universal heat seal tester (10) and method is provided for simulating heat-sealing processes. The tester (10) includes a pair of sample holders (11, 12) each of which hold a sample (20). A heater (30) is removably placeable between the samples (20), and the invention can simulate a hot-air side-seaming section of a cup machine. The method and apparatus test heat seals between the samples (20) while simulating real manufacturing processes, specifically heat sealing process, and can simulate other types of heat-sealing processes, such as ones relating to liquid packaging machines, which include electric, gas-fired, hot-air, induction, and radiant heating. The method and apparatus can be run automatically to eliminate operator variability.
