Apparatus for driving detaching rollers in textile combing machines

An apparatus for driving detaching rollers of a textile combing machine provided with a frame, a combing cylinder, a differential gear connected to said detaching rollers and a drive means connected to said differential gear for imparting a uniform rotary motion thereto, comprising a first link motion mechanism for creating a basic variable rotational motion cycle corresponding to a pilgrim step motion cycle of said detaching rollers in one complete rotation of said combing cylinder comprising a forward and rearward rotation thereof and a forward rotation thereof at a very slow speed and/or stopping rotation thereof, a second link motion mechanism for adjusting said basic motion cycle, said first link motion mechanism being driven by said drive means while said second link motion mechanism being driven by an output of said first link motion mechanism, an output of said second link motion mechanism being transmitted to said differential gear mechanism wherein said uniform rotary motion is superimposed with said output of said second link motion mechanism so that a predetermined pilgrim step motion cycle is imparted to said deteching rollers.
