Abstract: A napper fabric processing machine implements a number of improvements. First, the worker rolls are aluminum, reducing their weight and attachable to the cylinder using a quick release mechanism, enabling quick replacement. The worker roll are also easily serviceable and accessible from the side of the machine. Further, carding wear is monitored electrically by detecting torque generated by the motors driving the worker rolls. Finally, a tensioning system is used for the drive belts, negating the need for cylinder disassembly to replace the belts.
