Abstract (en)
[origin: US4373233A] A drive system for a drawframe for a rove drawing process in which the drawframe includes at least one pair of feed rollers, at least one pair of sleeves, at least one pair of drawing rollers, and at least one swinging arm on which one feed roller, one sleeve and one drawing roller of each pair is supported, the swinging arm being displaceable between an inoperative position and an operative position where the pair of feed rollers, pair of sleeves and pair of drawing rollers are engaged under pressure for rove drawing. The drive system includes a drive shaft and at least one displaceable friction clutch roller which is displaceable between an operative position to engage both the drive shaft and one of the feed rollers for transmitting drive from the drive shaft to the feed roller, and an inoperative position where it is disengaged from the feed roller, the friction clutch roller being displaceable into its operative position to allow progressive engagement of the drawframe at start up.
