Drive system for carding machine doffer, crush and calendar rolls

A fiber processing system for the front end of a textile card, comprising a doffer cylinder, a crush-roll pair and a calendar-roll, pair rotatively mounted in progression respectively from back to front on the front end of frame means of the textile card, a gearing means on said doffer cylinder, a timing unit having a timing drive pulley and timing gear combination rotatably mounted on said frame means for tandem rotation, said timing gear of said timing unit engaging said gearing means on said doffer cylinder, drive means including speed reduction means for directly driving said doffer cylinder, a timing slave pulley on one end of one roll of each of said crush-roll pair and calendar-roll pair, at least one timing belt connecting said timing drive pulley to each of said timing slave pulleys of said crush-roll pair and calendar-roll pair for rotating each said pair at speeds proportional to the speed of rotation of said doffer cylinder, and meshing gear means on the opposite end of each said one roll and on the adjacent end of each other roll of each said pair for causing the two rolls of each said pair to rotate in tandem.
