Problem to be solved: to provide a method for reducing the marking process of the position of sewing the half eye thread into the ear ligament. Further, an automatic preparation process for sewing the half thread into the ear rope is provided. Applied sewing machines for sewing automation provide an acceptable way for simple industrial sewing machines.Solution: an automatic feed out means for deploying the netting 2 in the lateral direction and drawing out the pair of ears 48A and 4B through the insertion of the autistic threads 4A and 4B through the insertion and insertion in the middle form, and a shaping means 11 for automatically sending the orbiter and the half eye thread to the sewing position 13 of the sewing machine, and a constant size feed means for sending the orbiter and the net with a prescribed dimension, the seaweed, and the seaweed It is a fixation automation means for fixing the aquaculture network to the ear rope.Diagram【課題】耳綱に半目糸を縫着する位置のマーキング工程を削減する方法を提供する。又、耳綱に半目糸を縫着する準備工程の自動化を提供する。縫着自動化するための適用ミシンは、従来の工業用ミシンに、簡単な改造で許容出来る方法を提供する。【解決手段】網地2を横方向に展開すると共に全半目糸3に耳綱4A、4Bを中挿し状で通して繰り出す自動繰り出し手段と、ミシンの縫着位置13に、耳綱と半目糸を自動的に送りこむ整姿手段11と、耳綱と網地を規定寸法で送る定寸法送り手段で、海藻養殖網を耳綱へ固着する固着自動化手段とする。【選択図】図1
