Method and device for cleaning yarn defects

摘要

Method for cleaning yarn defects on spinning machines, in which a yarn is spun and then wound on a bobbin (8) while monitoring the yarn for a characteristic and interrupting the production of the yarn (7 ) is carried out and the spinning machine is at least partially stopped, characterized in that when a setpoint deviation Abspullänge between the point of the first occurrence of the setpoint deviation to a yarn end produced thereafter is determined that at least two error categories are specified with associated Abspullängen and the occurring Setpoint deviations are each assigned to an error category and that individually or in combination Moire error, S-error or short-thick point error, L-error or long-thick point error or C-error or number errors are specified as a respective error category.
