Abstract

Abstract Translated from Japanese (57)【要約】 【目的】 旧粗糸を所定の位置で確実に、しかも粗糸を 構成する繊維を切断せずに繊維を素抜く状態で切断を行 う。 【構成】 粗糸継ヘッド5をドラフトパート上方の粗糸 継作業位置に配置して、粗糸継ヘッド5の先端に設けら れた粗糸案内溝13に粗糸ボビンからドラフトパートに 連なる紡出中の旧粗糸R1を導入する。次に粗糸寄せ部 材24を待機位置から作用位置に移動し、粗糸案内溝1 3に導入された旧粗糸R1の切断すべき箇所にコーム1 8を係合させた状態に保持する。バックローラの回転に よりコーム18と係合状態で移動する旧粗糸R1の繊維 の一部をコーム18より粗糸ボビン側に保持してコーム 18よりドラフトパート側の旧粗糸R1を細くする。次 に粗糸継ヘッド5をドラフトパートから離れる方向に回 動させて旧粗糸R1を切断する。 (57) [Summary] [Purpose] The old roving yarn is cut at a predetermined position without fail, and the fibers constituting the roving yarn are cut without removing the fibers. [Structure] The roving splicing head 5 is arranged at a roving splicing operation position above the draft part, and a roving guide groove 13 provided at the tip of the roving splicing head 5 is spun from the roving bobbin to the draft part. The old roving R1 inside is introduced. Next, the roving thread shifting member 24 is moved from the standby position to the working position, and the roving thread guide groove 1 is moved. Comb 1 at the position to be cut of old roving R1 introduced in No. 3 Hold 8 engaged. A part of the fibers of the old roving R1 that moves in engagement with the comb 18 by the rotation of the back roller is held on the roving bobbin side of the comb 18 to thin the old roving R1 of the draft part side of the comb 18. Next, the roving splicing head 5 is rotated in a direction away from the draft part to cut the old roving R1.
