    摘要: 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.

    摘要: A method and apparatus to remove a defectively inserted weft thread includes preventing the severing of the weft thread from the ready supply of weft thread, releasing lengths of weft thread less than twice the width of the material from the ready supply of weft thread, blowing the released weft thread by pulsating blowing into the shed containing the defectively inserted weft thread, severing the newly inserted weft thread and the defectively inserted weft thread from the ready supply, and removing the weft thread from the shed by pulsating blowing of the weft thread.

    摘要: A tucking-in device for weaving machines includes a thread clamp (10) for gripping the free ends (16) of inserted weft threads (4), and a tucker arm (12) for drawing the thread ends (16) from the closed clamp (10) back into the shed (6). The tucking-in device includes a pneumatic cleaning mechanism (14) for cleaning at least the thread clamp (10) by means of an air jet (15).

    摘要: Method for repairing the thread supply in weaving machines in the event of an interruption between the weft thread supply package and the weft accumulator, with the characteristic that it consists essentially of: seizing an existing thread portion at a particular point of the thread supply on the weft accumulator drum; removing the portion of thread between this point and the point of the interruption; taking a new thread end from the same weft thread supply package or another and leading it to the old weft thread end; and joining the new end to the old end.
