THREAD MATERIAL CUTTING DEVICE

摘要

A thread material cutting device is provided which is used in an extraction bag sheet manufacturing apparatus, the thread material cutting device having a compact apparatus configuration without the use of a cutter. An extraction bag manufacturing apparatus with the thread material cutting device incorporated therein includes welding means (first sealing device) in which tags retained on a carrying face of a carrier at prescribed intervals and a thread material arranged so as to be placed over the tags are press-heated and thereby welded on the carrier. 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.
