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.
