Abstract:
A variable speed drive system for a carding machine employs a variable pitch pulley assembly that rotates the feed cylinder and doffer cylinder at a constant slow speed as the sliver is made up to the coiler can, and after a predetermined time lapse the speed of the feed cylinder and doffer automatically and progressively increase at a fixed speed ratio from the slow speed condition to a constant high speed condition. If the sliver is not made up properly within the time lapse, the operation of the feed cylinder and doffer cylinder is automatically terminated.
