Abstract
A device for modulating a first rotational motion of an input shaft (2) to a second, different from the first, rotational motion of an output shaft (3)in textile machines has a fixed complementary cam (1) provided with at least two cam profiles (1 a, 1b). At least one cam follower (5) is linked to the input and the output shafts (2, 3) and is provided with at least two contact rollers (6a, 6b), each following a different cam profile (1a, 1b), because of which the cam followers (5)are performing a rocking motion. The cam profiles (1a, 1b)arc internal cam profiles.
