    • The plant performs, even in partial temporal superimposition:
          - a cycle of pirn predisposition for carrying out the doffing of cops (S), comprising: turning the pirns right side out in the same direction; transferring the pirns; positioning the pirns in their rack support; and preloading the pirns;
          - an automatic cycle for the doffing of cops (S) comprising the steps of: partial running-in of the bench (5), carrying out the fastening of the cop (S) and the underwinding; lowering the cop doffing group (54) with the feeding bench (5) at standstill partially removing the cops from the spindle rod (19) with the breaking off of the yarns (F); lifting the winding faller sickles (22) as far as a position that does not hinder the successive removal of the cops; completing the step of the removal of the cops from the spindles until said cops are overturned onto the unloading belt; positioning the cop doffing group for the insertion of pirns on the spindles; performing the insertion of the pirns; lifting the cop doffing group (54) up to the dead top point; unloading the cops beside the machine, separating the cops from empty pirns and storing them away;
          - a step for the predisposition of packs (CN) of feeding material (bobbins) with manual positioning of the new roves within clamp means (82);
          - an automatic cycle of bobbin replacement with: cutting of the rove under work; removal of the exhausted (or partially exhausted) bobbins (C) from the feeding bench (5); possible transfer of the partially exhausted or reeled off bobbins to a loading station; positioning of the feeding bench in the predetermined position for the bobbin replacement and simultaneous winding of the yarn on the cop; stopping of the spindles; transfer of previously predisposed full bobbins (CN) to the work position in contact with the feeding drums (7); transfer of the new rove and superimposition thereof to the one under work, and junction of the roves.
    • 该工厂进行,即使在部分地在时间叠加: - 纬纱管倾向用于执行警察(S),其包括的落纱周期:在打开pirns在相同方向rightside出来; 传递环的pirns; 定位pirns在他们的机架支持; 和预加载pirns; - 在用于警察的包括以下步骤的落纱(S)自动循环:长凳的局部磨合(5),进行COP(S)和所述底卷绕的紧固; 在静止状态下部分地除去从主轴杆(19)与所述开断警察断纱(F)的与进给台架(5)降低COP落纱组(54); 提起绕组坠落镰刀(22)尽可能的位置做不妨碍连续除去警察的; 完成去除锭子警察的步骤,直到所述警察被推翻走上搬出带; 定位所述管纱落纱组用于在主轴pirns的插入; 执行pirns的插入; 抬起到上死点处的管纱落纱组(54); 卸载机旁边的警察,分离空pirns警察和将它们存储起来; - 用于供给材料的包(CN)(筒管)与夹具装置中的新罗夫手动定位(82)的易感性的步骤; - 在筒管更换用的自动循环:下工作粗纱切割; 从馈电长凳去除耗尽的(或部分耗尽)的筒管(C)的(5); 部分耗尽或一连说出筒管装载站的可能的转移; 在用于更换筒管预定位置进给工作台的定位和同时卷绕在管纱的纱线; 主轴的停止; 此前易患满管的转移(CN)的工作位置中接触与输送鼓(7); 新的粗纱和叠加的传输其到一个下工作,并结粗纱。
