    • The present invention relates to a ring spinning machine and a method for spinning yarn. The ring spinning machine comprises per spinning position a drafting unit (1) for drafting a fibre roving (2) before ring spinning the fibre roving to a yarn. The drafting unit comprises with respect to a path of the fibre roving (2) through the drafting unit a lower entry roller (3) and an upper entry roller (4), a lower middle roller (5) and an upper middle roller (6) and lower exit roller (7) and an upper exit roller (8). Thereby, the upper rollers (4, 6, 8) are arranged such that they are pressed against and driven by the respective lower roller (3, 5, 7) in an operating state. Furthermore, the drafting unit comprises a compactor roller (9) and a compacting element (11). Hereby, the compactor roller (9) is arranged downstream with respect to the upper exit roller (8) and such that in the operating state said compactor roller is pressed against and driven by the lower exit roller (7). The compacting element (11) is arranged in the operating state between the upper exit roller (8) and the compactor roller (9) and comprises at least three laterally spaced apart compactor channels (14) forming alternative lateral locations for the path of the fibre roving (2) in the operating state.

    • 环锭纺细纱机的纤维须条输送机构,包括罗拉墩(31)、铰接在罗拉墩上的摇架(9),罗拉墩(31)上沿出线方向依次活动设有后罗拉(32)、中罗拉(3)、前罗拉(1),摇架(9)上沿出线方向依次活动设有后罗拉胶辊(35)、中罗拉胶辊(4)、前罗拉胶辊(30),中罗拉(3)和前罗拉(1)之间的罗拉墩上设置下销(2),下销(2)上表面的中部设置弧形面,下销(2)上方设置上销盖板组件,上销盖板组件包括与下销(2)弧形面凹凸相配的弧形面的上销盖板(6)、环形输送带(7)、盖板支撑件(13)和涨紧件,环形输送带(7)套在上销盖板(6)和中罗拉胶辊(4)外表面上;上销盖板(6)靠近前罗拉胶辊(30)的头部上设置向下弹性加压机构,由此可以抵消环形输送带(7)回转产生的拉力和涨紧弹簧(8)、涨紧块(5)对上销盖板(6)头部的抬升力,能够使上销盖板(6)、环形输送带(7)与下销(2)之间形成稳定的间隙,从而使纱线质量稳定,减少意外牵伸。
