<p>The present invention relates to a method of producing an interwoven seam interconnecting two portions of a woven structure, especially for the purpose of making an endless woven band for use, for instance, in the paper-making industry. The invention is further related to an apparatus for performing the above-mentioned method. Up to now, the production of such interwoven seams . was accomplished exclusively manually in such a manner that the ends to be interconnected were frayed, that is, the transversely extending or web weft threads were removed therefrom, to the depth of about 100 to 200 millimeters and over the entire width of the web, and then the weft threads of the one end portion were woven into the other end portion at the warp threads thereof Inasmuch as the distance between the individual threads is t in many instances, very small, many times smaller than 100 micrometers, the manual weaving of the seam threads is a very laborious and time-consuming operation. It is especially difficult for the seam weaver to make sure that the next thread gripped by him or her is indeed the thread which comes next in the order of the threads of the respective array. Thread by thread, he or she must make sure that indeed the correct thread of the respective array has been taken out of this array. Should it, for instance, happen that the thread which should have waited for its turn one more time is mistakenly taken out of the respective array and interwoven with the threads of the other array instead of the next thread of the first-mentioned array, there is obtained a so-called crossing fault which makes the entire woven structure worthless and which must he removed in a laborious repair operation. Experience with this manual seam weaving operation has shown that many manhours are lost in</p> |
