ABSTRACT:
A carding method in which the rotary flats of a carding machine are driven intermittently so that each time the flats are driven only a portion (1/6 to 1/4) of the flats opposed to the cylinder of the machine are replaced by fresh flats, thereby decreasing the amount of good fibers in the waste, particularly when carding synthetic fibers.
The carding machine is provided with a solenoid clutch in the drive mechanism for the rotary flats and the flat cleaning means, and with a timer for controlling the clutch so that the flats can be intermittently driven at desired drive and stop intervals. For carding polyester fiber, the drive interval may be enough to replace one-fifth of the flats opposed to the cylinder of the machine with fresh flats, and the stop interval may be as much as sixty minutes.
