[0055] Specifically, operating the ninth cylinder 1002 can cause the wire hook 1003 to be extended and retracted to perform the weft thread hooking operation; operating the tenth cylinder 1004 can cause the wire cutter 1005 to be extended and retracted to perform the weft thread cutting operation; turning on the fourth motor 1007 to cause the wire removing wheel 1008 to rotate, the excess weft thread on the weft tube can be pulled out and removed.

[0056] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
