Strip Coil
Strapping Machine
SMB-DC
The SMB-DC Strapping Machine features a heavy-duty design with a galvanized steel frame and stainless steel strap guides, making it ideal for the toughest environments near the downcoiler.

High-performing strapping in
the toughest environments
The machine is made to withstand the toughest conditions possible with extreme temperatures and high moisture levels.
Reliable
Durable materials and a simple yet innovative design makes this strapping machine very reliable and low maintenance.
Advanced sealing technology
Equip the machine with the strapping head of your choice. Sund Birsta offers a wide selection of strapping heads capable of creating seal-less mechanical joints or welded joints.

Operation
When a strip coil arrives at the strapping position, the SMB-DC immediately positions itself and the strap guides align through slots in the conveyor. Strap is fed through the system and into the Strapping Unit. Once the strap is clamped, the movable strap guides retract, and the Feeding Unit pulls back a portion of the surplus strap while the Strapping Unit centers itself on the coil for optimal strapping conditions. The Strapping Unit then advances towards the coil while the remaining strap is retracted by the Feeding Unit. The Strapping Unit performs the seal, cuts the strap, and retracts to its initial position. If a second strap is necessary to mitigate the spring-back force, the machine can perform a second strap in the same position by repeating the cycle. Otherwise, the coil can be further conveyed.
