ABSTRACT:
A high production textile card system is provided with an automatic variable speed drive system for driving the doffing cylinder from the main cylinder at a slow speed during system start-up and then progressively increasing the speed of the doffing cylinder after start-up. A variable speed belt drive system and clutch system are responsive to the sliver detector switch at the coiler can to control the rotation of the doffing cylinder after the system startup time has elapsed, to either terminate the rotation of the doffing cylinder if the sliver has not been properly threaded through the coiler head, or to increase the speed of rotation of the doffing cylinder with respect to the speed of rotation of the main cylinder.
