Abstract
A process and an arrangement for re-starting a previously interrupted spinning process in a spinning arrangement is provided. The arrangement includes a drafting unit which can be shut down and also an airjet unit including a vacuum chamber. For the purpose of removing an initially inhomogeneous fiber stream, a staple fiber strand, delivered by the re-operating drafting unit, is temporarily suctioned as waste via a deflecting device after it has left the drafting unit. Only then, when a homogeneous fiber stream has formed, is the staple fiber strand joined with a thread which is transported through the airjet unit. The inhomogeneous fiber stream is removed with the aid of the low pressure in the vacuum chamber.
