(54)	Combing machine with variable speed circular comb

(57) A combing machine envisages, between a motor (21) and a circular comb (20), a transmission device (30) having in input a motor shaft (36) with angular input speed (Win) and in output a driven shaft (19) with angular output speed (Wout), engaged with the circular comb (20). The ratio (R) between the angular output speed (Wout) and the angular input speed (Win) being defined, said ratio is variable depending on the angular position (α) of the circular comb and is between 1.55 and 0.45. In particular the ratio (R) depending on the angular position (α) is defined by the graph shown in figure 7.
