Description

圧縮装置２０は、さらに、吸引空気の流れを搬送するための搬送手段を備え、この搬送手段は、吸い込み開口３４の近くに圧縮される糸の輸送チャンバを画定するのに適する。 The compression device 20 further comprises transport means for transporting a flow of suction air, which transport means is suitable for defining a transport chamber for the thread to be compressed near the suction opening 34.

別の例では、第１の延伸シリンダ４ａが、軸方向に位置合わせされた別個のセクションと、同様に補助シリンダ１４ａとも備える、長い紡糸機などの別の例では、伝達グループ４００は、補助シリンダ１４ａのセクションの各々の端部に設けられる。例えば、第１の延伸シリンダ４ａが２つの軸方向に位置合わせされたセクションに分離される紡糸機では、補助シリンダ１４ａもまた、２つの軸方向に位置合わせされたセクションに分割され、４つの伝達グループ４００が提供される。 In another example, in another example, such as a long spinning machine, where the first draw cylinder 4a comprises a separate section axially aligned and also an auxiliary cylinder 14a, the transmission group 400 is an auxiliary cylinder. 14a is provided at each end of the section. For example, in a spinning machine in which the first draw cylinder 4a is separated into two axially aligned sections, the auxiliary cylinder 14a is also divided into two axially aligned sections and is divided into four transmissions. A group 400 is provided.
