Abstract (en)
[origin: EP0486896A1] In the stepped precision winding, the number of turns decreases from step to step. It can happen that it jumps into the critical range of a number at which mirror windings occur. Correcting actions disturb the winding operation, and the result of this can be that the number of turns is shifted from a critical range of low order into a critical range of higher order. The invention starts from the knowledge that the critical ranges are the narrower, the higher the ordinal number of the mirror value. According to the invention, the amount and magnitude of the correction actions are kept within narrow limits, whilst the differing width of the critical ranges is taken into account. The invention thereby makes it possible to prevent mirror windings up to higher ordinal numbers. The procedure according to the invention can be used especially for the winding of yarns made of synthetic material.
