Double Head Decoiler Machine

A double head decoiler machine is a metalworking equipment designed to improve the production speed and continuity of manufacturing processes. This decoiler aims to reduce the time required to load a new roll to a minimum by using two rolls, one of them as the driver, and the other as a backup.

Brief Profile of Double Head Decoiler Machine

The double head decoiler machine drives one of the rolls to uncoil the metal strip, while the other waits as a backup. When the driven roll is exhausted, the backup roll is readily connected to the driver within a very short period of time, minimizing production downtime. This approach allows for longer periods to load another spare roll, further reducing production time.

The double head decoiler machine is an ideal solution for production plants where speed and continuity are critical, particularly in serial manufacturing. It is commonly configured with an S-loop straightener, high-speed gear machine, and H-frame high-speed press machine, making it ideal for motor rotor and stator lamination stamping.

Overall, the double head decoiler machine efficiently and reliably uncoils metal strips while minimizing downtime and maximizing throughput, making it a valuable tool for large-scale manufacturing operations.

Application of Double Head Decoiler Machine

Usually, double head decoiler machine is equipped with the high speed press machine. This high speed coil feeding line combined double head decoiler, s-loop straightener, and cam feeder, speed can reach 60m per minute, design for motor and EI lamination stamping.
