A coil feed line is a machine used in the metal forming industry to feed metal coils into a press or stamping machine. It is used to automate the process of feeding metal coils into a machine, reducing operator workload and increasing production efficiency. The coil feed line consists of a decoiler, straightener, and feeder, which work together to uncoil, straighten, and feed the metal strip into the machine. The coil feed line is a critical component in the manufacturing process for industries such as automotive, aerospace, and construction.

A coil leveler is a machine used in metalworking to level and flatten coiled sheet metal. The machine is designed to unroll the coiled sheet metal and pass it through a series of rollers, which apply pressure to the metal and level it out. The coil leveler can be used to correct any distortions or imperfections in the sheet metal caused by the coiling process.
