A machine for making a continuous tubular element with filling from web material, including first and second means for feeding respective continuous webs, a forming station configured to perform a folding and/or deformation of a first continuous web in a shaped configuration, and a wrapping station wherein the second continuous web is wound in a tubular shape around the first continuous shaped web to obtain the continuous tubular element. Upstream of the wrapping station there is a first gluing device configured to apply at least one longitudinal line of glue on at least one of the continuous webs in such a way as to define at least one gluing zone, said longitudinal line of glue being positioned in such a way as to coincide with a zone of superposing and contact between the two continuous webs feeding out of the wrapping station.

A manufacturing machine and a manufacturing method for the production of a filter for a tubular element. There are provided: a folding conveyor, which moves at least one first pocket along a folding path, said first pocket being designed to house a sheet made of card stock and having an inner portion and an outer portion; a feeding station, where the first pocket receives the card stock sheet and engages the sole outer portion of the card stock sheet, leaving the inner portion of the card stock sheet free; a first folding station, where the inner portion of the card stock sheet left free by the first pocket is folded like the bellows of an accordion; and an insertion station, where the first pocket releases the card stock sheet having the inner portion folded like the bellows of an accordion.
