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.
