Abstract
There is provided a method of manufacturing a combustible heat source having a barrier affixed to an end face thereof, including providing a hollow die having a first opening and an opposed second opening; covering the first opening with a laminar barrier material; punching a barrier from the laminar barrier material by inserting a first punch into the hollow die through the first opening; placing one or more particulate components in the hollow die through the second opening; compressing the one or more particulate components to form a combustible heat source and affixing the barrier to an end face of the combustible heat source by inserting a second punch into the hollow die through the second opening; and ejecting the combustible heat source having the barrier affixed to the end face thereof from the hollow die.
