Abstract
In a multicolor air jet loom, a weft color which because of its long weft yarn repeat does not require picking for a considerable period of time and whose free end is damaged by the retaining air flow in the picking nozzle, is picked with an excess length equal to the damaged yarn part in the nozzle. The damaged portion of yarn is therefore not woven in and the resulting cloth has a defect-free edge zone.
