摘要

A compacting assembly (1) for an automatic cigarette filter manufacturing machine; the compacting assembly (1) having: a jet (5) through which filtering material is fed; an insertion finger (6) downstream from the jet (5); and an insertion unit (14) for inserting a thread (15) inside the filtering material, and which has a guide tube (16) defining a feed channel through which the thread (15) is run, and an adjusting device (17) for adjusting the position of an outlet opening of the guide tube (16); the guide tube (16) of the insertion unit (14) being connected to a fixed part by means of a spherical joint (18), which allows rotation of the guide tube (16) with respect to the fixed part about two perpendicular axes of rotation.
