Abstract
This invention relates to a device for drawing roves or slivers of fibers on a spinning machine with a view to converting this material into spun yarns, of the type incorporating pendulous arms, constituted essentially by an assembly comprising, mounted on the support frame of the machine, a series of splined shafts extending over the whole length of the machine and common to all the work positions, said shafts being driven in rotation and, on the other hand, presser elements constituted by rollers mounted on a pivoting support arm comprising means ensuring pressure of the presser rollers against the splined shafts, wherein the pendulous arm bearing the presser elements is assembled on the frame of the machine via a support comprising means for simultaneously separating the presser rollers parallel to the line of splined shafts.
