Abstract
An apparatus and method for correcting an irregularity during the insertion of a weft yarn into a weaving rotor of a series shed weaving machine involves drawing a length of weft yarn from a supply unit and delivering the weft yarn to the weaving machine in synchronicity with the weaving cycle. The length of weft yarn is inserted into a weft yarn conveyor apparatus and wound around a conveyor roller. A sensor is positioned between the supply unit and the conveyor apparatus to detect a weft yarn interruption, e.g., as a result of a weft yarn breakage or the yarn running out of spool. When the interruption is detected, the conveyor roller continues to deliver weft yarn stored in the storage apparatus until a complete weft yarn insertion into the weaving machine has taken place (i.e., weft yarn having a single loom width). The weft yarn is then cut at the insertion side of the weaving machine and the weaving machine is stopped. The weft yarn remaining in the weft preparation unit is then pulled back by the conveyor roller and discharged into a waste container.
