Abstract
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 ( ) with cooperating pairs of spreading cylinders. The spreading cylinders ( ) comprise flanges that engage into recesses of the opposing spreading cylinder. The spacing between the particular cooperating spreading cylinders ( ) 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 ( ) of the invention which process is associated with a high-precision dosing and high yarn uniformity.
