An open-end spinning device with an opening device for opening continuously supplied sliver material by means of a rapidly running opening cylinder, which opening device is arranged in front of a sliver spreading device (78) with cooperating pairs of spreading cylinders. The spreading cylinders (79, 80, 81, 82) comprise flanges that engage into recesses of the opposing spreading cylinder. The spacing between the particular cooperating spreading cylinders (79, 80, 81, 82) can be periodically varied. An unobjectionable opening process with a low speed of the opening cylinder and with a widened opening cylinder can be achieved with the sliver spreading device (78) of the invention which process is associated with a high-precision dosing and high yarn uniformity.
