1. A manufacturing machine (8) for the production of a tubular element (1) provided with a filter (2) at one end; the manufacturing machine (8) comprises:
an insertion conveyor (21), which moves at least one first pocket (23) along an insertion path (P3), said first pocket (23) having a tubular shape and having, on the inside, a seat (24), which reproduces in negative the shape of the tubular element (1) and is designed to receive the tubular element (1);
a first transfer station (S5), where the first pocket (23) receives the tubular element (1), which gets placed inside the seat (24);
an insertion station (S6), where a filter (2) is inserted into the tubular element (1) housed in the seat (24) of the first pocket (23);
a tubular inserting body (40) with the shape of a truncated cone, which is arranged in the area of the insertion station (S6);
a first actuator (25), which is designed to produce a relative movement between the first pocket (23) and the inserting body (40) so as to at least partially place the inserting body (40) inside the tubular element (1) housed in the first pocket (23); and
a pushing element (41), which is designed to push the filter (2) along the entire inserting body (40) until the filter comes out of the inserting body (40), so as to insert the filter (2) into the tubular element (1) surrounding the inserting body (40).
