Abstract
A sliver compactor is provided between a drafting roller of a drafting frame and the delivery unit which supplies the sliver to the spinning stations of the spinning machine. The sliver compactor has a shielding element juxtaposed with the perforated moving surface to which suction is applied and which reduces the suction force required to draw the fibers of the sliver into a compact form. The shielding element extends over a plurality of slivers and the respective spinning stations and a number of such shielding elements may be aligned over the length of the machine below the stretching field plane and secured on the machine frame.
