Abstract
A process for replacing spent roving packages with new roving packages, with automatic splicing and reattachment of the rovings, on machines to spin carded wool is disclosed. The new roving package is removed from a conveyor and brought to a waiting position, where the end of the new roving is manually placed in a gripper. When the old roving package is almost exhausted, the spindle of the spinning machine is stopped and the roving is sheared. The end of the roving still attached to the spinning machine is retained with an aspirator. The new roving package is then brought to the working position, causing the automatic discharge of the spent roving package, and the gripper brings the new roving to the aspiration site causing the intermingling of the fibers of the two rovings. The spindles are restarted and the spliced segments of the roving receives a false twist and subsequent real twists. The process may be carried out with a device which can remove the new package from the conveyor and bring it to the waiting position and the working position, which also has a gripper to bring the new roving the aspirator site.
