Machine to make tubular products (A), preferably straws, using one or more strip-shaped elements (B), preferably made of paper or its derivatives or suchlike, comprising: - delivery means configured to selectively deliver on at least one surface of at least one of said strip-shaped elements (B) an adhesive substance (S) containing at least a liquid solvent; - forming means configured to form said tubular product (A) by winding said one or more strip-shaped elements (B) in a helical manner and simultaneously gluing them, by means of said adhesive substance (S); - an evaporation apparatus comprising a plurality of heating elements for each of said one or more strip-shaped elements (B); each one of said plurality of heating elements has one or more electric resistances and is configured to selectively remove, by evaporation, at least a part of said liquid solvent contained in said adhesive substance (S); wherein each heating element of said plurality of heating elements is configured to be autonomously mobile at least between an idle position, in which it is located at a determinate distance from said one or more strip-shaped elements (B), and an operating position, in which it is in contact with, or in the proximity of, said one or more strip-shaped elements (B) and wherein said evaporation apparatus also comprises adjustment means associated with said plurality of heating elements , so as to selectively adjust the quantity of thermal energy transmitted to said adhesive substance (S) by acting selectively on the distance of said heating elements from said one or more strip-shaped elements (B) in order to vary their distance from said one or more strip-shaped elements (B), between said operating position and said idle position. - delivery means configured to selectively deliver on at least one surface of at least one of said strip-shaped elements (B) an adhesive substance (S) containing at least a liquid solvent; - forming means configured to form said tubular product (A) by winding said one or more strip-shaped elements (B) in a helical manner and simultaneously gluing them, by means of said adhesive substance (S); - an evaporation apparatus comprising a plurality of heating elements for each of said one or more strip-shaped elements (B); each one of said plurality of heating elements has one or more electric resistances and is configured to selectively remove, by evaporation, at least a part of said liquid solvent contained in said adhesive substance (S); wherein each heating element of said plurality of heating elements is configured to be autonomously mobile at least between an idle position, in which it is located at a determinate distance from said one or more strip-shaped elements (B), and an operating position, in which it is in contact with, or in the proximity of, said one or more strip-shaped elements (B) and wherein said evaporation apparatus also comprises adjustment means associated with said plurality of heating elements , so as to selectively adjust the quantity of thermal energy transmitted to said adhesive substance (S) by acting selectively on the distance of said heating elements from said one or more strip-shaped elements (B) in order to vary their distance from said one or more strip-shaped elements (B), between said operating position and said idle position. <EOS>
