Process and arrangement for restarting a previously interrupted spinning process

A process for re-starting a previously interrupted spinning process in a spinning arrangement, which spinning arrangement comprises a drafting unit including a vacuum chamber, wherein after shutting down the drafting unit, the process for restarting comprises the acts of:

• delivering a staple fiber strand upon re-operating the drafting unit;
• temporarily suctioning the staple fiber strand as waste via a deflecting device after the staple fiber strand has left the drafting unit wherein an initially inhomogeneous fiber stream is removed using a low pressure prevailing in the vacuum chamber;
• and
• joining the staple fiber strand with a thread transported through the airjet unit only when a homogeneous fiber stream has formed.

A spinning arrangement, comprising:

• a drafting unit which can be shut down when an interruption in the spinning process occurs;
• an airjet unit having a fiber feed channel, a thread withdrawal channel, and a vacuum chamber;
• a deflecting device for temporarily deflecting a staple fiber strand, delivered by the drafting unit, from a thread to be joined thereto;
• wherein the vacuum chamber is included in the deflecting device, the vacuum chamber being connectable to the drafting unit via a connecting channel.
