Abstract
The disclosure embraces a method of and apparatus for distributing linear groups of fibers onto a moving collector which include engaging and advancing groups of fibers by rotating pull wheels, disengaging the groups of fibers from the pull wheels by oscillating and rotating members associated with the pull wheels, oscillating the members by cam-actuated systems of linkage to control disengagement of the groups of fibers from the pull wheels and effect distribution of the groups of fibers on the collector, and applying pressure on the linkage systems opposing the operation of the systems to substantially eliminate lost motion in the linkage systems and thereby promote oscillatory motion accuracy of the fiber disengaging members whereby the collected body of fibers is endowed with substantially uniform characteristics.
