The operator slowly drags the coil to the automatic splicing platform, and the operation needs to be coordinated with the rhythm of the automatic unwinding of the air shaft. During the whole process, the main problems are: wider coil pole pieces, especially wide-width pole pieces, are difficult for one person to operate; the manually dragged pole pieces have inconsistent positions and uneven splicing.
