The document discusses pre-spinning processes in textile engineering. It describes three basic actions that occur between clothing of different rollers in carding: point to point action, which transfers material; carding action, which opens fibers; and back to back action, which cleans surfaces. The actions are part of preparing fibers for spinning and involve transferring, opening, and cleaning fibers between rollers.
