Abstract
A spinning preparation machine has consolidating means for producing a roving from a fiber bundle and a drafting system for drafting the fiber bundle. The drafting system is arranged upstream of the consolidating means in a transport direction of the drafting system. A guide is arranged upstream of the drafting system for guiding the fiber bundle between a container providing the fiber bundle and the drafting system. The guide has a feed segment opposite from the drafting system and a delivery segment facing the drafting system. The spinning preparation machine has a winding device for winding the roving onto a tube, and a tube transport device for providing empty tubes and/or for removing tubes loaded with roving by the winding device. The tube transport device has a conveyor for transporting empty tubes and/or tubes loaded with roving, wherein the conveyors are arranged at least in part between the feed segment of the guide and the drafting system.
