Abstract

Process for the manufacture of conical and cylinder-conical tubes, which is applied industrially, economically executed and which uses as a starting material, a rectangular band that is consumed entirely, characterized in that a band of variable width is prepared, which presents substantially the shape of a very long trapezoid, then this band is wound in a kind of helix of continuously variable diameter and the adjacent edges are joined by any means such as: welding, crackling, churning, stapling or the like, also being characterized by first trace the unfolded surface "ABDC" of the corner triangle cone at the vertex "α" you want to obtain, and extend the rectilinear sides "AC" and "BD" of the curvilinear trapezoid obtained until its intersection "S", then draw the circle "Γ 1" circumscribed to the triangle constituted by "S" and one of the bases of the trapezoid ABDC, as well as the circle "Γ 2" of center S passing through the two vertices of the other base of said trapezoid; on this circle Γ 2 we take a point "epsilon", which joins the two vertices of the trapezoid through which the circle Γ passes, the two lines thus obtained occupy respectively the circle Γ 2 at points "P" and "Q"; a tape is cut according to the curvilinear trapezoid limited by the straight lines ε P ε Q and the circles Γ 1 and Γ 2; this tape is wound according to a supposed helix of continuously variable diameter, forming the tape, with the axis of the supposed helix, an angle equal to: π sin (see formula) radians.
