Machine to make tubular products, preferably straws, using one or more strip-shaped elements, 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 an adhesive substance containing at least a liquid solvent; - forming means configured to form said tubular product by winding said one or more strip-shaped elements in a helical manner and simultaneously gluing them, by means of said adhesive substance; - an evaporation apparatus comprising a plurality of heating elements for each of said one or more strip-shaped elements; 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; 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, and an operating position, in which it is in contact with, or in the proximity of, said one or more strip-shaped elements 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 by acting selectively on the distance of said heating elements from said one or more strip-shaped elements in order to vary their distance from said one or more strip-shaped elements, 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 an adhesive substance containing at least a liquid solvent; - forming means configured to form said tubular product by winding said one or more strip-shaped elements in a helical manner and simultaneously gluing them, by means of said adhesive substance; - an evaporation apparatus comprising a plurality of heating elements for each of said one or more strip-shaped elements; 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; 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, and an operating position, in which it is in contact with, or in the proximity of, said one or more strip-shaped elements 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 by acting selectively on the distance of said heating elements from said one or more strip-shaped elements in order to vary their distance from said one or more strip-shaped elements, between said operating position and said idle position.
