Abstract
A machine for producing a tubular product by helical winding of strips of web material including a mandrel and a winding member to helically wind the strips of web material around the mandrel is disclosed. To improve adhesion between the strips, at least one pressure member is provided, cooperating with the mandrel, disposed downstream or upstream of the winding member with respect to the direction of advance of the tubular product being formed on the mandrel. The pressure exerted by the pressure member promotes adhesion of the strips forming the product.
