Beschreibung
Zusammenfassung:	Top roller for drafting systems in textile machinery comprises a cylindrical body with an outer sleeve of resilient material whose length is somewhat greater than that of the body. The sleeve is affixed to the body by flanges at both ends which leave a small gap between the cylinder and the inner surface of the sleeve, the flanges being inclined at an acute angle to the extended line of the cylindrical surface. The thickness of the sleeve diminishes from the central section towards both ends, with the ratio of the flange thickness to the central sleeve section being within the range 1:2 to 1:5. This construction gives a uniform stiffness along the length of the sleeve, and uniform pressure on the material being drafted, making it suitable for use in high-speed drafting systems.
