IWF 2231 Settings SPOOL BODY CIRCUMFERENCE The required pick length is the deciding factor when calculating the spool body circumference and the number of windings for each pick. The table below indicates the pick length ranges that can be obtained from different numbers of windings. - Page 6 IWF 2231 Settings YARN STORE The number of windings in the yarn store is regulated by the position of the yarn store sensor. The number of windings needed depends on the weaving machine's speed, the pick length and the pattern. Irregular patterns require larger yarn stores. Increasing yarn store variation will also require an increased yarn store.
