Abstract
A web of fibers delivered from a drawing machine is assembled into a sliver which passes into a guide duct, then passes between takeup rollers into a can coiler. Downwardly inclined air-escape holes are pierced in the wall of the guide duct in order to discharge the air entrained by the sliver. There is consequently no swelling of the sliver on the delivery side of the takeup rollers and no pressure rise towards the guide duct inlet, thereby facilitating the introduction of the web into the duct.
