Abstract
A thread material cutting device is provided which is used in an extraction bag sheet manufacturing apparatus. The thread material cutting device has tension application means such as a pressing plate configured to engage with the thread material placed between adjacent tags so as to apply tension to the thread material. While the welding means is press-heating the thread material onto the tags, the tension application means applies tension to the thread material so as to cut the thread material.
