Power Strapping Machines

Power strapping machines, the most efficient method for strap application, ensure uniform strap placement and load integrity. We manufacture the GCU SmartFlex corrugated unitizer, and the LBX-6520 and ISB corrugated bundlers.

GCU SmartFlex compression strapping machine

The GCU SmartFlex compresses and straps corrugated loads utilizing a modular head design for easy maintenance and operation. Learn more at our Smart Technology page.


GCU SmartFlex Features

Modular strapping heads

Separate, lightweight tensioning and sealing modules are easy to access and remove for maintenance, reducing downtime.

Strap placement flexibility
Innovative head spacing with five positions provides for variable strap placement options and minimizes the need for double stroking.

"Smart" dispensers
The strap feeding modules are mounted directly onto the dispenser framework, enabling simple one-step loading and feeding.


SignodeSmart data collection software

SignodeSmart, data collection software, measures unitizer performance versus capability in real-time. Easily integrated into the unitizer’s programmable logic controller (PLC), SignodeSmart provides real-time data reports allowing you to immediately identify improvement opportunities to increase production. Learn more at our Smart Technology page.



SignodeSmart Features

Real-time production data

From monitoring safety infractions to recording all attempts and errors at the unitizer, SignodeSmart captures and records crucial data to optimize productivity and minimize downtime for your operation.


MOD-GPX-6520 automatic corruated bundling machine

The new MOD-GPX 6520 automatic corrugated bundler features Signode’s modular design. The machine’s interchangeable modular components are built with productivity-enhancing features that help simplify operation and minimize service interruptions to provide unparalleled flexibility and longevity.



MOD-GPX 6520 Features

Each module can be quickly replaced by your own personnel for maintenance or desired upgrades without disrupting production. Locator plates, latches and electrical quick-disconnects ensure secure and precise alignment.

Built-in diagnostics
The MOD-GPX system has built-in diagnostics to simplify troubleshooting and minimize downtime. The Human Machine Interface (HMI) recognizes and identifies problem areas instantly to enable immediate correction.

Features that simplify operation

  • Upstream photo eye
  • Single compression
  • Variable speed reversible conveyors

Productivity-enhancing features

  • Patented automatic cut-off and refeed (ACR) automatically ejects misfed strap, rethreads itself and continues strapping
  • Work light in the accumulator area assists with visual inspections
  • Strap feeds from either direction
  • Out-of-strap feature ejects the strap at the end of the coil
  • Unique chute design provides consistent feeding
  • Quick release heat knife assembly speeds up routine maintenance
LBX-6520 corrugated bundler

The LBX-6520 plastic strapping machine increases production speed, optimizes performance and maximizes efficiency to save time and money. It is the fastest corrugated bundler in its class, automatically strapping up to 50 bundles per minute. It features our patented jam-resistant technology and automatic cut-off and refeed mechanism, making it the only truly operatorless corrugated bundler available.


LBX-6520 Features

Automatic cut-off and refeed

Signode's patented automatic cut-off and refeed feature automatically ejects misfed strap, rethreads itself and continues strapping without operator intervention.

Fewer Parts
With 40% fewer parts and more timesaving features, the LBX-6520 simplifies operation and maintenance to save you time and money.

Out-of-strap feature
The out-of-strap feature ejects the strap at the end of the coil to eliminate the downtime associated with removing the excess strap left in the machine.

ISB in-line corrugated bundle squaring and strapping machine

The ISB automatic in-line corrugated bundler improves production efficiency with reliable, high-speed, low-maintenance operation. It automatically squares and straps up to 30 bundles per minute in the flute direction as they exit the folder-gluer or other finishing equipment. The ISB is available in three basic models accommodating stack widths of 170 to 1300 mm, 1600 mm and 2,000 mm.


ISB Features

Increases productivity

At up to 30 bundles per minute, the ISB machine straps one bundle while squaring the next for maximum productivity.

Lower cost of ownership
ISB machines feature a simplified design with more durable wear parts, reducing maintenance costs and lowering the total cost of ownership.

Modular design
Available in three different models, the ISB's modular design allows for easy integration into any operation.

Modular Head Conversion

The Signode Unitizer Retrofit Program integrates our MHC modular strapping heads into CLM-8 and competitive strapping machines out in the field to simplify operation and reduce maintenance. The MHC modular strapping heads require fewer adjustments and have less moving and wearing parts, resulting in lower maintenance costs, increased productivity and a lower total cost of ownership.
