A fiber processing system for the front end of a textile card, the system having a doffer, a crush roll pair and a calendar roll pair rotatably mounted in progression respectively from back to front on the front end of the frame of the card, a gear on the doffer, a timing pulley-gear combination or unit rotatably mounted on the frame and having its gear engaging the gear on the doffer for either driving the same or being driven thereby, a drive motor drivingly connected to either the doffer or the timing pulley-gear combination for driving the system, a driven timing pulley on each of the roll pairs, and a timing belt system connecting the timing pulley of the timing unit to each of the driven timing pulleys of the roll pairs for rotating the same at speeds proportional to the speed of rotation of the doffer, and the roll pairs including gear means on the other ends of each roll for causing the rolls to rotate in tandem.
