Description

Technical Field

During the surface treatment process, feeding and receiving operations are usually required. The material strip is fed to the production line at a certain speed through the rotation of the coil reel, and a coil reel for receiving the material strip is placed at the discharge end of the production line. The processed material strip is slowly wound on it by the rotation of the coil reel to perform the receiving work.
