Abstract
A weft thread is inserted in a fluid jet loom by accelerating the weft thread to its insertion speed before the thread reaches the outlet of the main blower nozzle. The thread is accelerated to its insertion speed, for example, by an auxiliary nozzle upstream of the main blowing nozzle of the loom. Multiple weft threads may be inserted in a fluid jet loom by feeding each weft thread from a different supply source to individual weft thread supply channels and thereafter placing selected supply channels in communication with a through channel in a movable conduit block that selectively establishes communication between a single weft thread supply channel and the main blower nozzle. The conduit block can be mounted for various different movements to effect weft thread communication with the main blower.
