Automatic device for detaching the cam followers in a sewing machine where a selector knob, when it is rotated, provides the detachment of the cam followers in the first portion of rotation, and positions the desired cam in correspondence of the cam follower in the second portion of rotation. On the reduction collar of the selector knob two opposite grooves are made out, which engage pins transmitting the translation movement to a shaft which operates a cam follower detaching lever.
