PURPOSE:To obtain a sliver efficiently in one step, by charging raw cotton composed of short fibers in a hopper, drafting with a drafting device, and collecting in a can with a coiling device. CONSTITUTION:A well-opened and separated raw cotton 1 composed of short fibers is charged by the belt conveyor 2 into the hopper 8 consisting of a pair of aprons 3, and stored temporarily. The stored cotton is discharged continuously from the hopper through the bottom outlet port 9 to the drafting part 4, and drafted to form a fiber bundle 5 wherein the fibers are interlocked with each other. The fiber bundle 5 is collected in the can 7 with the coiling device 6 to obtain the objective sliver. Preferably, the outlet port of the hopper is attached to the bottom of the hopper, and is provided with a metering delivery function. |
