Abstract
A method for forming a vented end closure in a shirred food casing stick by forming an unshirred tail on the food casing stick, inserting a rod through the tail and into the stick, plunging the tail into the stick, and tamping the tail to form a closed end with a vent defined by the shape of the rod. A tamping rod may be used to pierce a tab on the opposite end of the food casing stock. Once pierced the tab can be ripped off the stick to leave a shard-free open end.
