Seal-Less Strapping Heads

  Seal-Less Strapping Heads

Model SL joint Model SL "Seal-Less" Strapping Heads

The Seal-Less joint is made by cutting a sealing profile into the two overlapping strap ends by the action of a die (fig.1) and a punch (fig.2).

The "SL" Strapping Head eliminates the cost of seals and the associated expense to inventory and the ordering process.

The "SL" Head is primarily suited for flat surfaces. The head is a modular design with the In-feed Guide & Strap Straightening, Gripper/Cutter and Sealing assemblies all being independent modules that can be replaced in a matter of minutes with a spare module, keeping down time to an absolute minimum.


Our Model SL Strapping Head has proven itself over the years in many 24/7 applications in the Automotive, Tobacco, Concrete Block, Lumber, and Container Industries.

Note: This Strapping Head is an economical replacement if you currently have an old, worn out or obsolete Strapping Head. We can easily retrofit your current strapping machine at a fraction of the cost of buying a new machine.
