Abstract
An adjustable control for weft thread delivery of an air jet weaving loom includes a system for selectively controlling the control time and the duration of master weft delivery jets in response to measurements made of weft thread delivery during the weaving process. Different types of weft threads are provided with their own master jets that are independently controllable as to duration time and/or control time. The duration and/or control time of auxiliary jets disposed along the shed of the loom are also controllable in response to detected weft motion. The system also includes a control system for the weft supply drums responsive to detected weft thread delivery during the weaving process.
