ABSTRACT:
Apparatus for securing a suspension thread to filter bags made of filter papers intended for infusion products, comprises means for attaching tags at regular intervals to a thread including, an intermittently rotatable member having a plurality of radial arms. Each arm carries means for gripping that thread portion with which a tag happens to be associated. The rotation of the rotatable member causes the thread to be unwound. A thread-cutting and tag-tilting station located downstream of the tag causes the tag to overlap the thread portion located upstream thereof, to form a kind of loop in the thread. Means are further provided for sealing at several points the cut thread portion, and related tag, to a web of filter paper arranged to run over the rotatable member.
