Apparatus for spinning line and work method for spinning line

The invention relates to an apparatus for a spinning line and a work method for the spinning line. The apparatus for the spinning line comprises a rail (22) of a roving frame (6), a secondary transport device (26) associable to at least one spinning frame (8), and an integrated device (50) to locally carry out the collection of several tubes (12, 14) originating from the spinning frame, of severalbobbins (10) originating from the roving frame (6), the exchange of the bobbins (10) with the tubes (12, 14) and the release of the bobbins (10) to the spinning frame and of the tubes (12, 14) to theroving frame (6). Rail moving means are further provided for, adapted to advance the rail (22) with a variable stroke (C1, C2) between the step of collecting the bobbins (10) from the rail and the step of releasing the tubes (12, 14) to the rail. 本申请涉及种纺纱线的设备和种纺纱线的工作方法。所述设备包括：粗纱机(6)的导轨(22)、与至少个精纱机(8)相关联的辅助输送装置(26)、以及集成装置(50)，所述集成装置用于局部地执行收集源自精纱机(6)的些管(12、14)、收集源自粗纱机(6)的若干绕线筒(10)、将绕线筒(10)与管(12、14)交换、将绕线筒(10)释放到精纱机并且将管(12、1
