SPIRO BETA 3 elbow machine

SPIRO BETA 3 elbow machine was built in 2018 in Switzerland by SPIRO International S.A. The machine is designed for the production of segmented elbows, duct reducers, duct end caps and other round-section fittings. It enables the forming of flanges, as well as the creation of lock seam along the edges of the segments and their permanent closing. This makes the SPIRO BETA 3 an excellent choice for manufacturing plants specialising in the production of components for the ventilation and air-conditioning industry.

The process begins with the preparation of properly cut sheet metal segments. The machine precisely forms their edges, giving them the appropriate profile to enable subsequent connection. The formed edge is then closed by a set of rollers, creating a permanent lock seam. The circumference speed of the rollers can be adjusted within a range from 0 to 40 m/min, allowing the operating parameters to be adapted to the type of machined material. The use of a lock seam increases the rigidity of the finished fitting and ensures a durable connection, while reducing the need for additional joining methods, such as welding. The BETA 3 elbow making machine therefore enables efficient, repeatable production of high-quality ventilation fittings. The total weight of the machine is 572 kg.
