the first roving and the second roving are respectively subjected to the drafting action of the drafting multiple of the back drafting zone in the back drafting zone, so that the fibers in the first roving and the second roving slightly slide mutually, the linear density of the first roving and the second roving is reduced, meanwhile, in the process of sliding the fibers, the fibers rotate along
