摘要：
A double-cylinder opener for staple fiber being pneumatically transported in an air stream, the two cylinders being parallel and mutually offset, the fibers passing firstly about the first cylinder and then about the second cylinder with spiral motion, the two cylinders forming two beaters of different action, which rotate at different velocities and are provided with different spike population densities.
