Abstract
Abstract In processing textile fibers a sliver of fibers is continuously delivered toan apparatus for receiving the sliver, cutting the sliver into predetermined lengths and storing these lengths, and providing the predetermined lengths of sliver to a next step in a process. A distribution device receives a longitudinally advancing sliver and delivers it to a first of a plurality of conveyor devices which delivers the advancing sliver to an associated storage container. After a predetermined length of the advancing sliver is stored in the container, the sliver is severed and the distribution device delivers the advancing sliver to another conveyor device for storing the advancing sliver in another storage container. The length of sliver stored in the first container is removed from the first container by the first conveyor device and is provided for delivery to a next step in the process. The length of sliver removed from a storage container is longitudinally advanced so that an end of the length of sliver at which it was severed from the advancing sliver is a leading end of the length of strand.
